Commercial Air Curtains

Commercial air curtains are typically used in commercial premises or large retail outlets over the doorway or entrances to separate the internal temperature from the external ambient temperature via an air stream. Thus the internal air is separated from the external air, and not escaping when the door is open and no contaminants are let into building. We classify a commercial air curtain with the ability to have a mounting height of up to 4 metres, making them ideal for saving energy in a retail outlet for example with an open door policy whilst preventing heat loss.

Air curtains commercial – Energy savings

Air curtains work by causing an air barrier with an air stream –

Air curtain working principle -suitable for shops, offices, hotels or warehouses and other commercial premises – keeping heat in or even smoke out of doorways

Air curtains work by creating an efficient and invisible door or air barrier that keeps the heat inside by separating the air between the environments of two different air temperatures, which makes financial sense as they reduce heat loss and ensure reduced heating energy costs.

When installed in an air-conditioned shop, office, loading bays, hotels, supermarkets or cold storage facilities, air curtains can be even more effective for these different purposes, keeping the warm air out and the air inside the room at the correct temperature range.

Climate controlled commercial premises

They are manufactured to produce a warm welcome or even a cool welcome for entrances to commercial premises , depending on whether the commercial air curtain has a heater built into the model , or is a fan only type model (commonly referred to as an ambient air curtain model).

Clean indoor air

With any air curtain it is essential that air curtain covers the entire door width to create a sealed entrance, either to keep the heated inside or cold air inside by keep the external environment temperatures from infiltrating into the building via the customers door entrance or openings and save energy usage.

The second important factor is the the jet or stream of air produced by the air curtain is powerful enough in range to get the airflow down to the doorways or entrances floor level.

Air curtain for commercial use

The most popular use for a commercial air curtain is to inhibiting heat losses typically from retail shops, banks, factories, food retail space or retails stores, a restaurant or healthcare environments and other commercial premises to create a warm welcome to customers or staff as they access a room environment via a door, doorways or entrance.

With a mounting height of up to 4 metres, these units cover many commercial applications

As well as other commercial premises where clean indoor air quality is a requirement – such as food service or food preparation controlled areas such as butchers or an abattoir – where keeping insects and dust out of the air is a requirement, especially in cold storage areas. This can be achieved with our commercial air curtains range.

We do three versions –

W – Water heat exchanger (1 or 2 row heat exchanger) unit – the two row unit is designated the 2R in the data table below
N –  Without heater elements thus “ambient air ” unit
E –  Electric heaters model

They are split into two different types or models within the air curtain range – which can be wall mounted or mounted horizontally above the  doorway.

Commercial ambient air curtains

They keep the heat or cooled air contained inside the building when using a commercial ambient air curtain, which relies on other energy heating sources to warm the space, as they have no heater element.

This type of air curtain just produces a jet or barrier of air either over the door space when installed horizontally over the doorway, or you can have a vertical installation with the air curtains being installed vertically at the side on a wall of the door space, entrances or opening.

When used in a vertical configuration we can cover an entire door width of 6 metres

A Door can be covered up to 6 Metres wide – when installed vertically

Commercial heated air curtains – heaters

These types of commercial air curtains are heated via a heating element. They are often referred to as door heaters air curtains, which is either ;

Electrically heated

Due to the kW outputs of the models, they normally require an industrial three-phase electricity supply to power the heater elements within the air curtain or door heaters, as some people refer to them.

Electric air curtains or electric over door heaters with “PTC” electric heating elements from Flexiheat UK

Our electric recessed air curtain range is very popular with hotels, shops and restaurants , as they can require a discrete air curtain above their access, doorways or revolving doors.

Hot Water Heated

Hot water heated air curtains, are very popular door heaters for commercial premises. The heater or heating element within the air curtain is fed by a wet heating system, which produces hot water for the door heaters heat exchanger, which takes this heat and transfers it into the warm air curtain and thus into the environment.

Recessed Air Curtains

We do a range of recessed air curtains which are very popular in large retail outlets and other commercial premises. Recessed air curtains models’ key benefits are that they are very discrete as they are covered and hidden in a suspended ceiling or bulkhead above the doorways for example. We have a dedicated webpage here – Recessed air curtains on our dedicated models.

Recessed Air Curtain Heater or Ambient Air Curtain
