Industrial Air Curtain Range

Industrial air curtains from Flexiheat UK

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%, and help with energy savings.

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 air curtains are ideal for use on loading bays, warehouses, hangars, retail outlet, cold stores 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.

It is important to note that air curtains work by producing an air stream, which must cover the entire door width or the entire door height to work properly, otherwise you will not get the benefits of energy savings or save energy from the installation of your commercial air curtain or industrial air curtain.

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 / air stream. 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 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 door width of the entrance of any industrial doorways such as logistic centres or any industrial premises.

This webpage goes through the industrial ambient air curtain range, the “Elis G ” industrial series , however our commercial air curtains range, called the “Elis T ” commercial series have their own webpage.

What is Ambient Air ?

The definition of ambient air with regards to an industrial or  commercial air curtain 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.

Working principle of an air curtain – industrial

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 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.

Horizontal Ambient Air Curtain – Made up of a 2 metre and a 1.5 metre module coupled together – This way doors up to 10 Metres wide can be covered (i.e. 4 x 2.5 metre Units)

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

Adjustable air distribution outlet which can be moved plus or minus 10 Degrees

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

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.
