Vertical Air Curtains – Ambient Air or Heated –  Electric, Hot Water or Gas

Vertical Air Curtains – Vertical door air curtains or vertical air doors are often used where entrances or doors are required to stay open for operational purposes, such as vehicle entrances ,loading bays or building entrances. Air curtains work by preventing the external air from entering the building or area by creating a forceful turbulence over the door way or entrance – thus reducing infiltration through the opening and  are also energy saving. Cold drafts can be avoided by heating the air if so required with our heated vertical air curtain units.

Heated vertical air curtain units  are most commonly used when additional or supplemental heat is required for an area to keep out the cold air, and also to eliminate the wind chill factor in areas with a colder climate.

Another advantage of these vertical air curtains is that the “curtain of air” is at high pressure also helps keep flying insects from entering the building, which the doors or entrance is open. A recent independent UK case study showed that the number of insects and bugs entering a building was reduced by approximately 78%, when using an air curtain. This is why some people refer to a vertical air curtain or “side air curtains” as some may refer to them, as an air curtain insect barrier.

Applications for these vertically mounted air curtains include cargo doors, customer entrances for shops ,office buildings, banks or any retail business, air plane hangars, goods inwards and goods outwards /despatch doors, restaurant doors, or any commercial or industrial applications.

Our vertical door air curtain units provide an efficient and powerful air barrier, and are a great solution for the doorways or entrances that can’t be covered by over the door air curtains, due to space or installation requirements such as revolving doors etc. As they are mounted at floor level, no drop rods are required for the air curtain installation, making a floor level install easier.

We do four versions of our energy saving vertical air curtain units which are sometimes called a floor mounted air curtain, in either a commercial version or an industrial version dependant on installation height.

You must cover the entire height of the door, for our vertically mounted units to be effective and prevent heat loss.

Our “Slim” designer / stylish range

Firstly our “Slim Range” these are an elegant, attractive design or stylish air curtain, which can be located on one side of the entrance or even revolving doors.

This air curtain range uses ac motors, ideally suited to reducing energy loss in retail premises, offices, restaurants etc in a stylish manner.

The ambient (non-heated) air curtain version can be vertically mounted on one side of the door and has an effective air flow range of 4 metres whilst the heated air curtain versions, to add additional heat to the air flow have a reduced air flow range of 3.5 metres.

 

Vertical air curtain – Commercial range

The commercial versions are designated the “Air stream” range, these air curtains can actually be mounted either horizontally or vertically. When mounted vertically, they can cover a door way or entrance that is up to 8 metres wide doors when used installed on both sides of the doorway for the ambient air curtain units, or 7.4 metres for the electric or hot water heated air curtian units  and up to 6 metres in height, at full output which should cover all of your door way requirements.

These vertically mounted air curtains are available in three options, either an ambient air version, electrically heated units or a lphw or lthw water heated units.This energy efficient air curtain range has “EC” fan motors for even greater energy efficiency as EC motors enable stepless control of the air flow.

We do a gas version vertical units, for this option you have to look an our gas fired industrial vertical air curtain unit, which is detailed at the bottom of this web page.

 

The Air Stream range of vertically mounted air curtains are available in lengths of 1, 1.5 or 2 Metres, and are available in non-heated or ambient air version, electrically heated or lphw (low pressure hot water) / lthw (low temperature hot water) water heated units and are a slim design for a vertical mounting application.

Thus, if your doorway is 3 metres high, you can couple together a 2-metre unit and a 1 metre unit, to achieve the vertical coverage of door. These wall mounted air curtains are fixed with the bracket set to wall next to the door or even revolving doors.

The range includes 1 model of 45 kW Output. We also supply an ambient range, which is not a heated unit, which uses the surrounding ambient air to produce a powerful air curtain .These vertical door air curtains are designed to create a horizontal air barrier across the door in order to protect against the cold outside air, and to avoid any heating loss from inside the warehouse or building to the external air .The FAC-V gas fired range are used to protect doors from 2 to 4 metres high and up to 4 metres wide.

Vertical door air curtains – with Ambient Air, or Heated Air by electric or hot water 

We now have developed a new and improved industrial vertical air curtain range, which either uses the ambient air of the building or are available in a heated option. The heated vertical door air curtains can be powered by either electricity, which has to be three phase or by hot water, with a maximum temperature of up to 130 degrees C and up to 16 Bar in pressure.

These vertical air curtain units can be used in different combinations of lengths to cover roller shutter doors or up and over doors that are up to 7.5 metres high, in a vertical door air curtain configuration, and cover doorways or entrances that are up to 13 metres wide, when installed on both side of the doorway.

These industrial vertical air curtain range are basically modules that can be coupled together to make up your desired height for your industrial or commercial overhead roller shutter type door that you need to cover- not exceeding 7.5 metres in vertical height. The ambient models are available in either 0.5, 1.5 or 2 metre lengths whilst the heated versions (electric – three phase or hot water) are available in 1.5 or 2 metre lengths, and have adjustable outlet grilles.

This range of industrial vertical air curtain units is designated the “Elis G” range, and look like the below picture when installed on a commercial / large industrial doors.

 

 

Ambient temperature is the air temperature of any environment where the vertical air curtains are installed. The adjective ambient means “relating to the immediate surroundings.” Thus the air pushed through these air curtains is the air temperature of the building or warehouse in which they are installed.

These vertical air curtain units provide a powerful curtain of air across an opening or door way, preventing warm or cool air escaping from your building or preventing the ingress of cold or warm air from entering, depending on the season. They help minimising energy costs and maximise not only comfort, but also convenience.
