Industrial & Commercial Air Curtains – Factories, warehouses, cold rooms and retail premises are all subject to the problems caused by frequently opened doors. The open door not only causes discomfort but greatly increases energy loss and, therefore, the running costs of the building. An air curtain or sometimes referred to as an air door from Flexiheat UK offers an energy efficient, cost-effective solution to these problems by reducing heat loss by up to 80%.
In winter periods, these air curtains protect against heat loss in areas by producing an air-stream suitably directed that protects the entrance from the ingress of cold air into the heated space. In the summer period, these ambient air curtains may be used as “cooling device” by preventing the entry of warm air from outside as well as air pollutants entering your commercial or industrial building.
These industrial & commercial air curtains are ideal for use on loading bays, warehouses, hangars or factories, saving forklift drivers time as they don’t have to get out of their cabs to close and open doors , and make moving from one area to another safer and more convenient. Unlike plastic slat curtains, which quickly become opaque with use, an air curtain provides 100% visibility at all times.
Industrial Air Curtains – Our ambient air curtain uses the air of the room to create a barrier at the opening of the door. The air curtains are constructed with axial fans and have an efficient air diffuser, that ensure a strong and powerful air barrier. The range consists of 3 models a 1.5 metre, a 2 metre and a 2.5 metre long unit or module. These industrial & commercial air curtains are used to protect the doors up to 8 metres maximum in height horizontally or 10 metres in height vertically and can be installed horizontally or vertically to suit your site requirements. The Flexiheat “Elis G” range of ambient industrial air curtains protect against uncontrolled incoming airflow. They help to save energy by delivering a powerful air barrier across the entire width of the doorway or entrance.
The first part of this webpage goes through the industrial ambient air curtain range, the “Elis G ” industrial series and lower down the webpage is the commercial ambient air curtain range, called the “Elis T ” commercial series.
What is Ambient Air ?
The definition of ambient air with regards to industrial and commercial air curtains is in reality ambient temperature – In an air curtain context, ambient temperature is the air temperature of any environment where air curtains and related equipment are located. The adjective ambient means “relating to the immediate surroundings”- Thus these are not heated air curtains – they just use the ambient air within the building to cause a high pressure air curtain to prevent the interior of the building from the ingress of air from the outside, and thus losses of heat. There are additional benefits that these air curtain provides in protection against pollution, dust, fumes, undesirable odours and insects.
We have heard people refer to ambient air curtains, as unheated or non-heated or even neutral air curtains.
Commercial Air Curtain / Industrial Air Curtain for overhead doors /roller shutter doors
We now have developed a new and improved industrial air curtain designated the “Elis G” series, which uses the ambient air to produce an air curtain, that can be mounted up to 8 metres maximum in height horizontally across the door way . The units can be used in different combinations of lengths to cover roller shutter doors that are up to 10 metres wide ,which covers the majority of commercial or industrial air curtains for overhead doors requirements.

Vertical mounted ambient air curtains- industrial
As sometimes there is no installation room above the overhead industrial / commercial door, then these Elis G air curtains can be installed in a vertical orientation. When installed vertically on one side of the doorway, the maximum width of the doorway should be 8 Metres.
When installed vertically on both sides of the door, the maximum width we can cover is 14 Metres
We can cover doors up to 10 metres high in a vertical air curtains configuration.
This industrial air curtain range is intended to be used in regions or areas with a moderate to cold climate, where temperature ranges from minus 10° Degrees C to plus 40° Degrees C and a relative humidity up to 80% (at the temperature of +25°C), they should not be used in rooms containing any flammable and/or combustible substances, biological substances or in environments with corrosive air vapours.
There are three models or modules of these industrial ambient air curtains, the either a 1.5 Metre long unit, 2 Metre long unit and a 2.5 metre long unit. They are basically modules or units that can be coupled together to make up your desired width or height for your industrial or commercial overhead roller shutter type door.
To increase the effectiveness of the air curtain they have adjustable outlet nozzles for varying the air flow direction. These adjustable nozzles enables the air direction to be adjusted to plus or minus 10 Degrees, allowing more adaptability to the site conditions

Cold Room Air Curtain – Industrial
The Flexiheat “FHIAC” models are an improved range of industrial air curtains that are temperature rated from minus 25 degrees centigrade (-25C ) to plus 60 degrees centigrade ( +60C) which makes these units the perfect solution as a cold room air curtain . They provide a powerful ambient air seal across the opening of cold rooms or refrigerated stores to prevent the cold air from escaping and warm air from entering the cold room or refrigerated area. These cold room air curtains remove the requirement fast acting shutter doors or plastic strip curtains, ensuring that forklift drivers and staff are given total visibility, and the added convenience of unhindered access and most importantly improving safety to all concerned. The other benefits of the air curtains when used in a cold room / freezer / or chiller stores application are –
- An energy saving solution- a study has shown energy savings of over 50% when compared to an open door -an ever increasing important factor for the industrial and cold users
- A constant climate in the cold room /store – also a significant reduction in the formation of icing and misting
- Faster logistics and easier access – No waiting for a door to be opened or going through plastic slat curtains, which you have to do slowly to ensure good safety standards
This range of cold room air curtains is suitable for mounting up to 7 metres in height, or can blow up to 7 metres horizontally. These air curtains for cold rooms, come in a modular format of either 1.5 metre or 2 metre lengths, just like our other industrial air curtains, except they can operate in temperatures down to minus 25 Degrees Centigrade.

Industrial Air Curtains
These industrial air curtains are fitted with axial fans that force air out through the exit slot that has directional louvres fitted. The high velocity air stream will also reduce the ingress of airborne contaminants as well as insects into the space being protected, ensuring a pleasant environment.
These ambient industrial air curtains are situated to the side or above industrial doorways and create a powerful barrier across the opening keeping heat in whilst providing total visibility and access.
Commercial Air Curtains – Ambient
We also do a range of commercial ambient air curtains that can be mounted up to 4 metres in height. This range is called the “Door Guard Ambient Range” -and are designated by having the letter “A” after the width of the air curtain. These units benefit from a modern design, having a low noise level and reduced weight. They are available in 3 widths or sizes ;1 metre – designated the “100A”, the 1.5 metre is designated the “150A” and 2 metres long heater is designated the “200A”, All of this range of commercial ambient air curtains are powered by a single phase / 240-volt electrical supply, and an electrical protection class of IP21.
These commercial ambient air curtains or over door air curtains are more aesthetically pleasing, but have a lower performance with regards to the airflow throw they can produce as opposed to our industrial range. This commercial door air curtain range can be used on commercial doors or openings that are up to 4 metres in height, and are only available in single phase electric powered versions.
This commercial door air curtain range is controlled either by a controller which can be mounted either near the air curtained door way or can be mounted wherever the person controlling the air curtain is situated (which allows a maximum of 2 of these ambient air curtains to be controlled via one controller), alternatively and more commonly they are often controlled by a magnetic door switch, which automatically operates the ambient air curtain on opening and closing of the commercial door. These commercial air curtains have a two-year warranty, and are a fully CE approved product.
This door guard range of ambient commercial air curtains can also be fitted with a BMS module, which allows the delivery of basic signals to a Building Management System, should you require this facility or option. This BMS module allows you to monitoring the operation of the commercial air curtain (Emergency/Failure signal) and switches the air curtain on or off from the master BMS system. With the use of digital signals 0/1 (potential or Volt free contact), the module can work with any BMS master protocol without the need to convert the signal.
These “Door Guard” commercial air curtains benefit from a twenty-four months parts only warranty and are suitable for installation in supermarkets, large retail outlets, warehouses, car showrooms, service stations, sports and show halls, exhibition centres to name a few of these commercial applications
