Specification facts to know about Air curtain manufacturers!

 

What makes good air curtain?

An Air curtain technically, is a fan-powered air device that automatically creates an invisible air barrier wherever it is being installed. It is mostly used over the doorway to separate efficiently two different environments and it makes this separation without limiting or interrupting the access of the people or vehicles on the premises. Air curtain manufacturers make sure that they are highly operational and progressive.

There are many Air curtain manufacturing units and their worldwide users but not all are fully aware and familiar with its usage and specifications. Thus, we have listed some characteristics and tips that all users should keep in mind to choose the right product.

  • The first and foremost important thing is the height of the door
  • Choose an air curtain according to the width of the door
  • The location of the building should be the determinant factor for the level of protection needed against weather conditions
  • Use air curtains if the focused building has several doors in the same area,
  • If the building has several stories connected by escalators/stairs
  • Air curtains are best to measure pressure differences between the inside and outside of the building
  • Door characteristics also matter to choose an air curtain, if frequently closing and opening, then go for sensor based device, or else manual.
  • Characteristics of the ventilation and air conditioning installation
  • Voltage and electrical power availability also affect the performance of air curtain
  • What type of business, location, and office equipment are there is also vital to get the appropriate product.
  • The fitting style of an air curtain is also responsible for its performance such as free hanging or recessed, horizontal or vertical installation, heated or unheated, etc.

Air curtains and their manufacturing specifications

However, there are different sorts of air curtains available as per the industry usage. So, herein we have mentioned some of them for your information and knowledge.

Air Curtains Supplier in India- Things to Consider Before Selecting a Vendor

 

Air Curtains Supplier in India

With air curtains supplier in India, Selecting a vendor is one of the most crucial tasks before selecting an air curtain. A reliable vendor will understand your needs and help you choose the air curtain that is best suited to your requirements. There are various important factors listed below that you must consider before selecting your vendor:

  1. Manufacturer: You should know the original source i.e. from where your vendor procures the machines. The manufacturer must be a reputed one in the field and enjoy great goodwill in the market.
  2. Experience: To a great extent, the experience of the vendor decides his reliability. Better experience implies a better understanding and knowledge of market conditions and customer requirements. Therefore, it becomes imperative to analyze the experience of the vendor.
  3. A number of installations: Choose the vendor who has already served for a number of years. Get to know the number of installations done by them within the country and around the world (if any). A large number of installations would imply better knowledge and a better understanding of the field.
  4. Technically Equipped: Their production unit should be technically advanced in terms of working and delivery. It will provide a better breakthrough in the competitive market. The vendor should be able to guide you on various kinds of flow patterns and workability and should be able to customize a solution whenever required.
  5. Warranty and part Availability: Many vendors commit to a warranty that is beyond their scope. As an international standard, a manufacturer should be able to provide support for all the parts and make them available for a minimum tenure of 10 years. Generally, traders overcommit and shed their responsibility when parts are needed.

What should be the Right Velocity AsPer AMCA/NSF Guidelines

Everyone in the industry struggles with the above question and many times, engineers out of their experience or some thought specify velocities at different points, either on top of the door or on the floor, etc.

The Air curtain Manual by AMCA Specifies the right velocity parameters. The same is mentioned in NSF Guidelines also.

The velocity specifications as mentioned in AMCA Publication, 222-08 Application manual for Air Curtains, are as follows:

Application Manual for Air Curtains; Section 8.6.1.2

8.6.1.2 ANSI/NSF37- Air Curtains for Entranceways in food and food service establishments. The NSF standard establishes criteria for ACU air performance, construction, design, and material type. An ACU construction that complies with this standard is considered by the food service industry to provide effective flying insect protection to an entryway by deterring flying insects from entering through the opening or nesting in the ACU. These criteria can be summarized into basic principles that are intended to create a clean and healthy environment.

  1. Laboratory Methods of Testing Air Curtain Units for Aerodynamic Performance Rating: This AMCA standard defines the test methods that can be used to generate data for the typical types of air curtains performance. This data can then be used to compare different models for aerodynamic performance. Note that the data generated from the tests described in the standard does not define an ACU’s relative effectiveness.

If the data is measured and generated from an AMCA accredited laboratory, the product can be licensed to bear the AMCA seal (if applied for) under AMCA 211, Certified Rating Program- Product Rating Manual for Fan Air Performance. The AMCA Seal represents the fact that the ACU has been independently tested by a third party, adding credibility to manufacturer ratings.

The performance data generated, as defined by ANSI/AMCA 220 and simplified here, are:

  • Average Outlet Velocity- The mathematical derivation of a velocity flow rate by dividing the air volume flow rate by the air curtain discharge area. This value should be used with outlet velocity uniformity to compare different ACUs.
  • Velocity Projection- The average of the peak velocities measured along the ACU discharge nozzle at predetermined widths at specified distances away from the ACU. These values can also be used to determine velocity uniformity at said specified distance.
  • Outlet Velocity Uniformity- This is a measure of the consistency of the discharge velocities across the ACU width expressed in a percentage determined by a standard deviation method.
  • Airflow Rate- Physically measured by a recognized air volume test chamber using ANSI/AMCA 210, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating.
  • Power Rating– This is the electrical power actually consumed by the entire unit(in KW) during the Air Volume Flow Rate; not to be confused with the mechanical energy equivalent to the unit horsepower.
  1. Air Curtains Entranceways in Food and Food Service Establishments: The NSF standard establishes criteria for ACU air performance, construction, design, and material type. An ACU construction that complies with this standard is considered by the food service industry to provide effective flying insect protection to an entryway by deterring flying insects from entering through the opening or nesting in the ACU.

These criteria can be summarized into basic principles that are intended to create a clean and healthy environment. The air performance defined in this standard is geared toward protection from flying insects.

The opening types are defined by three categories:

  • Customer Entryway
  • Service Entryway
  • Drive through Window

Each type has its own minimum performance requirement.

  1. Customer Entryway: The Customer Entryway test requires a maximum mounting height declaration and a minimum air velocity of 3.05 m/s (600fpm). Velocities are measured within 200mm (8 in.) deep by ACU nozzle width wide area broken into 50mm*150 mm (2in.*6in.) grids, 0.9m (3ft) from the floor.
  2. Service Entryway: The service entryway test requires a maximum mounting height declaration and a minimum air velocity of 8.15m/s (1600 fpm). Velocities are measured within a 75mm (3in.) deep by ACU nozzle width wide area broken into 75mm*150mm(3in.* 6in.) grids, 0.9m(3ft) from the floor.
  3. Drive-through Window: The drive-through Window test requires only a minimum air velocity of 3.05 m/s (600 fpm), 1/3 the distance of the vertical opening above the service window countertop. Velocities are measured within a 200mm (8 in.) deep by ACU nozzle width wide area broken into 50mm * 150 mm (2 in.*6 in.) grids.

The design and construction requirements are intended to prevent the nesting of vermin, the accumulation of dirt, debris, and moisture; and to provide accessibility for servicing, cleaning, and inspection.

The material requirements are intended to ensure that the equipment is resistant to penetration from vermin and wear with the respect to food safety (i.e., the effect of food, heat, refrigerants, cleaning, and sanitizing compounds).

Lastly, ACU units can be tested, certified, and listed to standard ANSI/NSF 37 by nationally recognized testing laboratories and certifying bodies that have a food service program. Some of these agencies include NSF and the corresponding NSF Mark, UL.

How to Take Sizes of an Air Curtains?

 

Air Curtain Sizes

For Air Curtains Supplier, there is a Contrary to the common belief, that taking the measurement is actually a child’s play. With only a single piece of equipment, i.e. a measuring tape, this job can be done easily.

It is important to know just 3 basic pointers:

  • 1. Width of the door
  • 2. Height of the door
  • 3. Space available above the door Checklist/selection guide

You can even go to the link to watch the video https://www.youtube.com/watch?v=JcrGHe_NE04

Factors that will drastically hamper the Air Curtain’s performance

Factors that hamper the Effectiveness of Air Curtains Supplier

Typically air curtains work well in many facilities such as production and industrial buildings, stores, transport terminals, car services, garages, markets, shopping complexes, drying houses, etc. But the proper installation of air curtains is necessary to ensure their proper working.

There are a few other factors that can affect the efficient working of air curtains such as

    • Negative Pressure:If the facility has exhaust fans or gravitational ventilators and no supply air or there is a difference between the exhaust and supply air (i.e. the latter is less than the former) the negative pressure is created.
    • In these kinds of conditions the volume of air moving out from air curtains is also sucked in the facility along with the outside air and hence air curtains become ineffective.
    • High Wind Velocity:When the outside Wind Velocity is too high as in the case of storms, it will disrupt the flow pattern created by the air curtain on the doorway. So, whenever the outside wind velocity of the curtain, it will get disrupted.
    • Horizontal Gap between Wall and Machine:If the horizontal gap between the wall and the machine is too wide, the performance of air curtains will be drastically reduced. An air curtain should be installed close enough to the door so that there is no leakage from the sides of the door. The gap should be less than 50mm, for maximum effectiveness.
    • Vertical Gap between the Nozzle and the top of the Door:If the vertical gap between the nozzle and the top of the opening will be wide, the effectiveness of the air curtains supplier will be affected. Ideally, the gap should be less than 100mm machine.
    • Sizing the Air Curtain:The Air Curtain should always be equal to the Width of the Door, for it to perform optimally. If the air curtain is oversized, it will require more energy than usual and if the air curtain is undersized, it will prove insufficient to fully protect the opening it has been installed above. This will lead to an unnecessary increase in costs because of energy wastage.
    • Placement of Air Curtain:When our primary objective is to discourage the entry of mosquitoes and flies, the air curtain should be installed outside. When installed outside, it becomes 4 times more effective to stop flies, than the one which is installed inside.

How to Save Rs. 420 Every Hour and Enhance Productivity?

Air is nature’s greatest gift to mankind and the quality of the air we breathe in affects not only our productivity but the quality of our life as well. Air curtains are one of the best and most cost-effective ways to maintain the quality of air within the premises and retain a hygienic environment.

Do you know air curtains can help us save millions of hard-earned money?

A simple mathematical calculation can prove this. Let’s see how:

Energy Calculation

E = m C ∆T
m : Mass of Air
C : Specific heat of Air at given Temperature
∆T : Temperature Difference

m = Density X Volume
Density of Air at 40˚C = 1.127 Kg/cu. Meter
C = Specific Heat = 1.005 KJ / (Kg ˚C)
∆T = Temperature Difference = 15˚C
(assuming the outside temperature is 40˚C and the inside is 25˚C)

Volume = Area X Velocity of Air from Door X Time of Opening
(Say : Door Size = 8ft X 4 ft
Velocity = 1 m/s = 200 fpm
Time of Opening = 1 min
Volume = 32 X 200 X 1 = 6400 cu. ft. = 181.22 cu. meter)

m = Density X Volume
(from Above = 1.127 Kg/cu. meter X 181.22 cu. meter
= 204 Kgs)

E = m C ∆T
= 204 kgs X 1.005 KJ / (Kg ˚C) X 15˚C
= 3075.3 KJ = 0.85425 KWh
Thus –
India if Per KWH cost of Power is Rs 8.10
The cost of Opening the Door of Size 8ft X 4ft for 1 min is = Rs 6.92

Cost of Running an Air Curtain of 4 ft = 400W (Input Power) for 1 minute = 6paise
Rate per Kwh X Time X Power Input
8.10 X 1/60 X 0.4 = 5.4 paisa

Net Saving = Rs 6.92 – 0.06 = Rs 6.86

Saving per Hour= Rs.7*60min=Rs.420 per Hour

Thus, you can see how Air Curtains help us save Rs. 420/hour. Also, they create a comfortable and amiable environment by keeping mosquitoes, flies, and other pollutants away.

An air curtain helps maximize savings by reducing energy loss and improving the effectiveness of our cooling/heating systems. They provide a risk-free alternative by shielding the premises without an actual physical door and are one of the best investments for a business.

Parameters to Consider Before Buy Air Curtains

Buy Air Curtains

When buy air curtains system, consider not only the main variables such as door height and door width but also other factors such as the building and climatic conditions.

Other influencing factors are :

  • The positions of the different doors on the floor, and if there are more than one, the positions between them: aligned, facing each other.
  • The different floors are connected by stairs, escalators, or ramps.
  • The pressure difference between the exterior and interior of a building.

According to climatic conditions, air curtains with a stronger, stronger jet and stronger heating capacity should be selected to prevent cold, heatstroke, and wind.

When choosing the type of heating, it is important to consider whether there is hot water or electricity available in the building. You can buy air curtains with electric heaters or heat pumps, which are more sustainable due to their energy efficiency.

There are two primary questions that need to be answered and understood:

  • 1. Will Air Curtain works for me?
  • 2. What are the parameters required to choose the Right Model?

Basically, there is very limited information you require to decide on the requirement of the air curtain:

The Basic information required to know, whether an air curtain will be suitable for your facility or not, is as follows:

  • Width and Height of the Opening
  • Negative Pressure in the facility
  • Outside Wind Draft
  • Purpose of Installation
  • Insect Control
  • Dust Control
  • Save Conditioned Air
  • Odour Control

With this basic information, we can judge whether the air curtains will work for us or not.

Factors affecting the selection of air curtains can be classified into 2 categories:

  • Primary Parameters
  • Secondary Parameters

 

Primary Parameters Secondary Parameters

 

Type Voltage
Flow MOC Blower
Mounting MOC Chassis
Fan Operation
Placement

The Primary Parameters include a variety of options that affect the performance of an Air curtain like

Types of Air Curtains:

  • Recirculating:The recirculating air curtain collects the exhaust air and directs it back to the air curtain inlet. This process is repeated continuously with a plenum built into the door, which is reconnected to the air curtain inlet via a duct.
  • Non-recirculating:Non-recirculating air curtains capture fresh air from the environment and exhaust it out of the unit. Since the same air is not recirculated, these air curtains may be referred to as non-recirculating air curtains.

Recirculating air curtains are more efficient than similar products, but non-recirculating air curtains are still more popular. Most of today’s units are non-recirculating units due to their cost-effectiveness and ease of installation.

 

Types of Air Flow in Air Curtains:

 

  • Top to Bottom:Top-to-bottom installation is the most common and economical way to install air curtains. Here the air curtain is mounted horizontally above the opening and air is blown out the door from top to bottom.
  • Sideways (L to R, R to L):Here the curtains are installed perpendicular to the floor and the air is blown left to right and right to left. Vertical drainage often requires curtains to be installed on both sides of the door, adding to the overall cost of installation. This type of installation is usually required where doorways are very wide or high.
  • Bottom to top:This type of installation is uncommon and is dedicated to hot furnace applications. Curtain panels require a special frame and are assembled at the door level, the installation is done under expert guidance.

Mounting

  • Surface Mounted
  • Recessed

Fan

There are three types of fans to choose from:

  • Centrifugal
  • Crossflow
  • Axial

Placement Air Curtain Inside/Outside

The air curtains can be easily mounted on either side; whether inside or outside the conditioned area. Usually, it is recommended that the equipment should be installed on the warmer side for optimum results. It implies, that when installing a heated air curtain under cold conditions, it should be installed Inside. In places where the temperatures are too high and the major problem are dust, flies, and saving the cold air, it should be installed outside to get the best results.

Even secondary factors play an equally important role in the selection of an air curtain. They include:

Voltage

The voltage output plays a major role in the selection of air curtains as these machines are specially designed to operate with the mentioned amount of electric outputs. For Indian markets, air curtains are designed with respect to these three outputs:

  • 220V/1 phase/50Hz
  • 220V/1 phase/60Hz
  • 440V/3 phase/50Hz

Otherwise, for the Saudi Market, curtains that work with 220V 1P 60Hz output are demanded. Air Curtains can also be installed in buses and are specially built for 24V/DC. Thus, information on voltage is important for picking out the right buy air curtain for you.

MOC for blower

MOC or the “Material of Cover” for the blower is another specification on the basis of which air curtains are selected. The covers are made of different materials to suit different requirements, such as:

  • Galvanized Iron
  • Plastic
  • Stainless Steel
  • Aluminium

MOC for Chassis

Chassis basically refers to the main mounting and the fixing plate of an air curtain. For the chassis, the customer usually has two options of either picking one of the two materials;

  • Stainless Steel 304 or
  • CRC Powder Coated

An air curtain consultant can help you in picking between various options.

Operation

    • Switch Operated
    • Remote

Technological Edge of Air Curtains Manufacturers in India

Air Curtains Manufacturers in India

Classification of Air Curtains manufacturers in India Based on Flow and Fans Type

Air Curtains can be mainly classified into two types:

  • Recirculating and
  • Non-recirculating Air Curtains

Recirculating Air Curtain gathers and returns the discharged air in the air curtains inlet. The process is continuously repeated with a plenum built into the door that connects back to the inlet of the air curtain via the duct.

Non- recirculating Air Curtain captures fresh air from the environment and discharges it from the unit. Since the same air is not recirculated back, these air curtains can be termed non-recirculating air curtains.

Recirculating air curtains are more efficient than their counterparts but still, non -recirculating air curtains are more popular. The majority of installations today are non-recirculating due to their cost efficiency and ease of installation.

Directions of Flow:

There are 3 possible directions of blow-out air streams, both for recirculating and non-circulating curtains:

  • Horizontal Mounting from top to bottom: Horizontal mounting is the most common Installation and most economical way to mount an air curtain. Here, the air curtain is installed horizontally across the top of the opening and the air is discharged from top to bottom of the door.
  • Vertical Mounting from left to right or right to left: Here, the curtain is mounted perpendicular to the ground and the air is expelled from left to right and right to left. Vertical discharge mostly requires mounting curtains on both sides of the door which adds up the total cost of installation. Normally, this kind of installation is required in places with very wide or high door openings.
  • Horizontal discharge from bottom to top: This installation is not very common and is specially used in the case of hot oven applications. The curtain units require special frames and are mounted at the door level and the installation is carried out under specialized guidance.

Type of Fans

Air Curtains can be designed and manufactured with various types of Fans. The three most commonly used fan types are:

Centrifugal

Most air curtain units employ centrifugal fans that use a forward or backward-curved impeller. Centrifugal fans make use of blades to drag air into a circular motion. The pressure of an incoming air stream is increased by blades mounted on a circular hub and alters the direction of the outward flowing air, usually by 90 degrees. Centrifugal fans move air radically and outwards through the vortex housing. Centrifugal fans provide a stronger and more stable air flow than axial fans and therefore, need a higher power input.

Axial

As the name suggests, an axial fan causes air to flow through it in an axial direction. The fan blades rotate around an axis and draw air in parallel to that axis. In other words, the air flows axially in and axially out which forces the air out in the same direction. The fan creates a pressure difference that forces flow through the fan.

Axial fans create a large volume of airflow, but the air flows they create are of low pressure. Therefore, these fans need a low-power input for operation. There is a wide range of axial flow fans. It may vary from low or medium-pressure fans to high-pressure fans. Because of the3 cool and low-pressure high-volume air flows they create, axial fans are best suited for many general-purpose applications.

Cross Flow

Cross-flow fans are derivative fans and comprise a housing with a rear wall and a vortex wall. Within that housing, there is an impeller surrounded by forwarding curved blades. When the air moves through a cross-flow fan, it flows transversely and passes through its blades twice.

In cross-flow fans, the air enters in a perpendicular direction to the motor shaft and is detected by the fan blades and expelled. These fans have a long, rectangular shape and use either an alternating current (AC) or direct current (DC) motor. These fans are also referred to as tubular fans or tangential fans because of their long and narrow shape and airflow pattern. Unlike centrifugal fans, in cross-flow fans, the air flows through the fan itself rather than through an inlet. They provide a high-pressure coefficient and are preferred for their low noise. The most common application for them is a split air conditioner.

All the above types of fans have their own advantages and disadvantages and can be used for different kinds of applications.

Mitzvah Air Curtains: Worried about CAPEX (Capital Expenditure)? No Problem!!!

Mitzvah Air Curtains

The protective barrier provided by Mitzvah Air Curtains keep harmful chemicals away from your valuable products and machinery. This reduction in pollution reduces the wear and tear of parts and other useful machinery and maintains the quality of your product.

If you are worried about Capital expenditure, No problem Mitzvah is here:

  • Mitzvah Air Curtains payback period

The payback period is the time it takes to recoup the cost of an investment. Simply put, it is the period of time it takes for an investment to reach its limit. Air curtains construction and energy saving feature, result in a very fast payback period of up to 6 months in air conditioning systems and as little as 4 months in hot oven applications. The quantity of payback varies based on the place and context of use.

i. Payback in a less busy area

The air curtains help to maintain the barrier that separates the outside and inside environments, therefore keeping the temperature stable. And, since there is less movement in areas like offices, shops, and personal spaces, the payback period is quite short and can be easily verified before and after 4 months.

ii. Payback at a place with moderate movements

Payback assumes the above-mentioned estimate, which shows that an air curtain saves on average Rs 7/minute, so a big store or major shop on average works 8–10 hours a day and 26 days a month (Sunday closed). The monthly savings will be roughly Rs 12,000, for a total savings of Rs 60,000 in 5 months.

iii. Payback in locations where there is constant movement

Wherever there is constant movement, the air curtains have to work hard and forever to maintain a consistent air temperature. As a consequence, with continued usage, it will use more power and, as a result, the investment can be restored in less than 6 months. Mechanical components may wear and deteriorate with prolonged use, resulting in increased costs.

Effect of Air Curtains Price on CAPEX

Capital expenditures, or “CapEx,” is the sum of money spent by a company to purchase, upgrade, and maintain physical assets such as land, buildings, plants, and equipment. The main goals are to protect the company’s assets and keep the cash flow positive. So, in this case, the air curtain does the things that are needed in a more efficient manner. Air curtain has been called a “cash cow” for any business because it brings in a lot of money over time for a small initial investment. With a payback period of only four to six months, it has no effect on costs but does lower BTL by lowering operational expenses and increasing margin.

i. Air Curtain in Itself is a cash cow with low investment and high returns.
ii. With a payback period of just 4-6 months, It has no effect on costing rather it lowers the BTL, by lowering the operational cost and hence increasing the margin.
iii. Thus money invested in CAPEX will give a reduction in operational cost.

By avoiding leakage of conditioned air and keeping the mosquitoes and flies away, mitzvah air curtains help increase the comfort level of both external customers and internal employees. A comfortable environment and satisfied employees result in increasing the overall business efficiency.

3 Common Misconceptions about Air Curtains Price

Air Curtains Price

An air curtain, also known as an air cutter and air door, is a machine that blows a controlled airflow across an opening to the other side to create an airtight seal. This seal separates different environments while allowing for a smooth, uninterrupted flow of traffic and unobstructed views through openings. In this blog, we discuss misconceptions about air curtains price.

Consider the following factors when deciding on an air curtain:

  1. The height of the installation is measured from the discharge diffuser to the floor.
  2. The building’s location will determine the level of weather protection required.
  3. The pressure differential between the interior and exterior of a building.
  4. Electrical power supply availability and voltage level
  5. Business types, building styles, and interior design

The following are some common misconceptions regarding the air curtains price:

  1. There is no difference in cost between different sizes or lengths of air curtains.

There is a widespread misconception that all air curtains of the same size and length should have the same cost. This is not the case. On the other hand, the price is not so much determined by the external components as it is by the internal ones. In addition, there are two distinct varieties of air curtains: those that are heated electrically and those that are not. Additionally, the electrical one is the more expensive option.

  1. The price of the Air curtain will be significantly higher as the size is large

This is a completely false notion that has been passed down from generation to generation, as the cost of the air curtain depends entirely on its dimensions. It is not true that standard or domestic air curtains are the same sizes as commercial grade air curtains because commercial grade air curtains are larger. The construction of the self-supporting casing, which ought to be done using galvanized steel plate, is what establishes the price of the item. A filtering capability ought to be built into the inlet valve. Because of this, there is no longer a requirement for any additional maintenance or pre-filtering to be done. The use of double-inlet centrifugal fans, which are powered by an external motor and generate very little noise, drives up the cost of the product significantly. And perhaps most importantly, those air curtains with a rating of 5 stars help in reducing energy consumption, which results in them being comparably more expensive than air curtains with lower ratings.

 

  1. Even the most expensive air curtain is going to be perfect for all of your applications.

In India, there is a widespread misconception that the higher the cost of an item, the more beneficial it will be. The truth is that each curtain is made to order in accordance with the space, the customer’s requirements, and the intended purpose. In addition, the cost of installing commercial air curtains in a residential or community grocery store would be excessively excessive. Why would you spend that much money on an air curtain when you could get one that is significantly cheaper? 

There are 3 Common misconceptions about Air Curtains Price

  1. All Air Curtain works the same.

This is the most common feature that every air curtain possesses it is a device that uses a fan to force a curtain of air downward known as an air curtain. The forced air creates an invisible barrier that prevents warm or cool air from entering a doorway or building through an opening, thereby aiding in temperature regulation. Air curtains are also used to prevent insects, dust, pollen, and other contaminants from entering an interior space.

However, the original use of the Air curtain is primarily determined by the location and function of its use. And, in terms of function, air curtains are available in a variety of styles, each with its own set of capabilities.

  1. Velocity is the only parameter to measure the quality of the Air Curtain

Velocity refers to the speed of the motor and then the fan, but apart from this, the main characteristic of the Air Curtain is how much nominal Airflow it produces which is in m3/h. The low-pressure air curtain produces nominal airflow ranging from 1700-3200 m3/h and the High pressure (commercial purpose) air curtain produces the nominal airflow ranging from 1800-7200 m3/h. In order to achieve such airflow the amount of energy consumption is also important. More efficiency and less consumption are the other parameters to check the quality of the air curtains. Apart from the velocity, a good quality air curtain produces minimal noise. 

  1. The misconception is that air curtains are simple fans put on the door.

A fan is a powered machine that circulates air. A fan is a rotating arrangement of vanes or blades that act on the air and are typically made of wood, plastic, or metal. An impeller, rotor, or runner is a rotating assembly of blades and a hub.

Whereas an air curtain is a fan-powered device that creates an invisible air barrier over a doorway to effectively separate two environments while allowing people and vehicles to pass through.

Difference between a fan and an air curtain:

  1.  A fan has less velocity than the air curtain.
  2. A fan consists of a less powerful motor which makes it slower than the air curtain, thus helping to create a barrier or the two environments.
  3. Fans won’t be able to stop pathogens from coming inside while an air curtain helps a lot.
  4. A fan helps to ease the heat wave whereas an air curtain works as both a normal and heated air curtain.
  5. The air velocity of a regular fan is between 2-3 m/s whereas the velocity of an air curtain is between 15-17 m/s.
  6.  It is not possible to cover a large doorway used in commercial places while air curtain comes in varied sizes.

FIND ADVANTAGES OF BUY AIR CURTAINS FROM MITZVAH

Buying Air Curtains

The air curtain – is one of the types of innovative equipment designed to prevent heat loss of a building through the planes of door or door openings in places with high traffic: in industrial shops, public and residential buildings, shopping centers, warehouses, and restaurants. In other words, it device, also known as an air door blows a controlled stream of air across an opening to the other side to create an air seal. While air curtains are not the same as air conditioners, they are highly effective at maintaining the interior temperature. They are sometimes referred to as “invisible doors” as they create an invisible barrier between inside and outside environments. Sometimes referred to as fly fans. This seal separates different environments while allowing a smooth, uninterrupted flow of traffic and unobstructed vision through the opening. The air stream which is let out from the machine at whatever point the entryway opens causes no limitation in development. Buy Air curtains at a range in price depending on features. Air curtains are available with horizontal or vertical installation, this is determined depending on local conditions.

What does the air curtain do?

An air curtain or air door is a device that prevents air or contaminants from escaping from one location to another. A typical air curtain design is a fan located above the building entrance, pointing downwards. Well, if you’re an engineer, site manager, or architect, you probably don’t have everything you need to know about the benefits and prices of air curtain systems.

FUNCTIONING

Generally, the air in the curtain entering through the inlet grille, sometimes with filter functions, is compressed by internal fans and forced through an air outlet, which is directed at the open doorway. The filter protects the interior components (heat exchanger, fans, electronics, etc.) from dust and particles. The fans of the air curtain can be direct or belt-driven. The most frequently used types are centrifugal, axial, and cross-flow some air outlets and/or lamellas can be adjustable to increase the performance of the air curtain according to each situation. Most air curtains are installed horizontally, across the top of the opening, and the air is expelled from top to bottom of the door. Vertical air curtains can be installed on one or both sides of the door.

Horizontal installation integrated on the floor is the most effective in thermodynamic terms and at the same time the most expensive one to install and problematic where public pedestrian traffic crosses the doorway for obvious reasons. So it’s only used in some special industrial applications. Types of air curtains: non-recirculating or recirculating. A non-recirculating unit discharges the air to the environment. Otherwise recirculating collects and returns the air from the discharged air. Recirculating air curtains are more efficient but the majority of installations are non-recirculating due to lower costs

In this blog, we’ll discuss the five main benefits of air curtains.

1) Air curtain saves space: First, the owner saved a lot of electricity by installing an air curtain, an energy-saving device. But air curtains can also reduce capital costs and maximize footprint. The Coz Air Curtain is easy to install and sits elegantly on top of the doorway.

2) These devices facilitate your employees:  Air curtains use less additional heat than other heaters, help improve employee comfort, and reduce sticking by providing drier floors in entry areas during inclement weather. This helps keep traffic flowing and improves hygiene by reducing insect intrusions and keeping dust and odors out.

3) Air curtains help you save your energy: Although the air curtain consumes electrical energy during operation, it can save net energy by reducing the heat transfer between the two rooms (this heat transfer occurs by mass transfer when the air in the room mixes at the edges).

A closed and well-sealed door is the ultimate solution to reducing energy loss. However, the benefits of physical doors are lost when your business has to deliver items to passersby entering and leaving for most of the day.

The task of the air curtain is to cool and heat the space where many customers enter which actually leads to a way of saving energy in many ways. Air curtains keep doors open late, inviting your potential clients into your center from the street. These devices also allow a large amount of conditioned air inside the building so that it cannot escape to the outside.

Air curtains and physical doors can be used together. When the solid door is open, the air curtain opens and minimizes air exchange between the inside and the outside.

Additionally, by reducing heating or air conditioning costs in a building, air curtains can pay for themselves within a few years.

4) Ease of Access and Design Flexibility:  Air curtains provide an invisible barrier without compromising the building design and provide concealed protection from external elements.

Additionally, air curtains are particularly effective in areas where the door is open for extended periods of time and the door needs to remain open throughout the day. These devices can then even be used above entrances that must remain open for operational reasons. In addition, air curtains are not only useful at the main entrance of the company but also installed at the entrance of car parks and food preparation areas, etc.

5) The payback period for air curtains is very short:  The combined energy and building savings of air curtains add up to a potential payback period of one to three years compared to more permanent and expensive buildings. in conclusion: Well, we want you to know all the essentials about buy air curtains.

Air Curtains

Before purchasing air curtains, we should know about air curtain in detail, what is air curtain, how does air curtain works, where it is used, and their advantages of an air curtain. In this blog we talk about air curtains and give you all detail about air curtains, that’s why you don’t have any confusion before buying air curtains.

Here it is,

What is an Air Curtain?

An air curtain also referred to as an air door is a mechanism that creates an air shield by blowing a controlled stream of air across the opening to the opposite side. This barrier separates different environments while permitting uninterrupted traffic flow and clear visibility through the opening. They help to contain heated or stimulated air in industrial or commercial configurations, resulting in significant energy savings and increased personal comfort. In addition, they prevent the infiltration of contaminants and insect pests. Mitzvah manufactures and distributes air curtain at an affordable price.

How does the Air Curtain work?

Air curtain perform their intended function because they generate sufficient air to establish a barrier that stretches the length of the entrance. Engineers designed this invisible airflow barrier to entirely surround the entrance and shield the inside from temperature-variable, pathogen-laden, and insect-carrying outside air. Even though this is not a physical barrier, it protects the doorway sufficiently.

  • When the air curtain is engaged, the air is sucked into the device via its intake.
  • The fan then accelerates the air as it enters the container of the fan.
  • This air goes into an inlet manifold, which distributes the air evenly along the length of the discharge port.
  • The propeller vanes on the nozzle make a flow of air that is mostly smooth and even.
  • The air expelled by the nozzle generates a downward-falling air current. 80 percent of the air returns to the intake side of the air curtain, while 20 percent travels in the other direction.

Where Air curtains are used?

Pretty much every single business can potentially benefit from an air curtain in some way. Heat transfer, obstinate insects, dust or pollen, and windy air are not limited to a specific business. Instead, these problems may affect every business in every industry. This means that air curtains could be used almost anywhere.

Air curtains provide customers with comfort while saving energy and keeping critters outside. Air curtain installation in commercial and industrial settings, including

  • Food Service (Quick Serve, Restaurants, Schools, and Cafeterias)
  • Healthcare facilities
  • Warehouse and distribution
  • Office and retail
  • Convenience and groceries
  • Manufacturing, transportation, and terminals
  • Indoor Grow Facilities and Processing Plants, and Food Processing Plants.

Advantages of Using an Air Curtain:

  • Huge energy savings: Air curtain systems minimise energy usage, operational costs, carbon footprint, and environmental impact. It uses the least amount of energy to keep a temperature difference inside or outside the building.
  • Climate Control: Air Curtain contribute to the creation of air temperature barriers between two locations. This section keeps the temperature inside more stable, which makes customers, visitors, and employees feel more at ease.
  • Pest Control: Flying insects such as bees and fruit flies may be a nuisance. They may contaminate food, ruin the wine, transfer disease, or provoke allergic reactions. Flying bugs hate air curtain and can’t get through them without getting confused and losing their balance.
  • Environmentally Safe: Air curtains provide the aforementioned benefits without harming the environment. To have an effect, the devices use just air, not chemicals or anything else that is hazardous to the environment.
  • Improve indoor air quality: An air curtain’s capacity to generate a non-obstructive air stream that keeps particles, dirt, and dust out enhances indoor air quality. It functions by recirculating indoor air over an open doorway, preventing the entry of outside air.
  • Stress-free system: Air curtain minimizes heat loss via workplace doorways. Less heat loss conserves energy. This might reduce the heating system’s demand and lengthen its lifespan.
  • Stop the foul odour: There are several unpredictable odours in the outdoor world. Your structure could be located near an industrial or urban area. By keeping out the outside air, an air curtain can stop bad smells from coming into a building.

Types of Air Curtain available:

There are several varieties of air curtains on the market presently. Some kinds of air curtains are those that are heated by electricity, those that use steam coils, and those that use gas.

  1. Ambient (Unheated) Air Curtains: Ambient air curtains are often used for pest and pollution monitoring, and they may be installed at any entrance. This kind of air curtain is often installed inside the door opening. Although indoor installations may aid with environmental management (by filtering out toxins, dirt, and allergens), ambient air curtains installed outside the door can help with pest extermination as well. These curtains are especially good for the environment because they use less energy to separate the air inside and outside.
  2. Electrically Heated Air Curtains: Electrically heated air curtains are used to keep chilly gusts at bay in locations that need extra warmth, such as open entrances. Heated air curtains are utilised in restaurants, hospitals, and retail businesses to optimise interior ambiance. When customers enter a facility from the chilly or windy outdoors, these curtains keep the frigid air outside and the warm, welcoming air inside. Because the heating feature may be switched off in the summer, this air curtain could be used all year.
  3. Steam/Hot Water Coil Air Curtains: These air curtains integrate into a building’s preexisting heating system. Almost all the commercial T buildings are heated with steam and hot water throughout the winter. Heat loss via open doors is a big issue in these places, so installing hot water or steam-based air curtain is an effective strategy to heat the threshold while keeping cold air out. In the summer, just switch off the heating component to utilise these air curtains.
  1. Indirect Gas-Fired Air Curtain: Indirect gas-powered air curtains are most often seen in warehouses, industrial complexes, distribution centers, and other big structures. Propane or gas is used to heat these structures. They lose heat attributed to frequent indoor and outdoor traffic. Keeping employees comfortable in these environments is critical for engagement and productivity. Indirect gas-powered air curtains contribute to this goal by providing a soothing atmosphere. Furthermore, many businesses and warehouses need consistent temperatures for sensitive items. Even when doors are opened and closed, air curtains may help to keep temperature variations to a minimum. In this scenario, indirect gas-fired units are especially beneficial since they provide protection from freezing temperatures and gusts of up to 30 miles per hour.
