Electric Air Curtains

Electric Air Curtains – We do three ranges of electric air curtain heaters, sometimes referred to as electric over door air curtains: a commercial, an industrial and reccesed models . All of these over door heaters are suitable for taking and heating the air from the inside of the premises via electricity to produce a warm welcome. They can be used in an ambient air mode, which does not heat the air, allowing for non-heated air circulation.

By using an electric warm air curtain in conjunction with an open doorway or opening, you can further reduce energy loss and significantly increase the air quality and comfort of your building.

 

Our electric warm air curtains provide extra protection for your door or entrance remain open and keep the heat and cold outside or inside as per your site requirements, and all this in an economical and aesthetic way.

These electrically powered air curtains are a modern solution that offers effective protection against heat, cold, dust and insects from the outside air.

In winter, these electric door curtains produce a warm welcome and prevent the warm air from escaping from inside the building or room, while in the summer they prevent warm or hot air coming from outside from entering the building, thus allowing the room, offices, reception areas, shops, restaurants or even a warehouse doorway or entrance to maintain comfortable temperature conditions for your customers or staff.

These air curtains provide fresh air and positively influence the temperature conditions inside the building or room where they are installed, helping to improve energy efficiency for the internal air.

Energy efficiency

Electric heated air curtains have a 100% energy efficiency on the heating elements.

Product range options

Our electric over door air curtain products come in a variety of styles, functionality and sizes to fit any doorway or entrance with effective heating and a powerful air barrier for environmental separation to prevent heat loss and ensure better air quality.

Airstream electric commercial air curtains

Our commercial electric heated air curtain models can be mounted up to 3.7 metres in height or 7.4 metres if installed vertically on both sides of the doorway entrance. This range is designated the Airstream “E”. These air curtains benefit from a modern design—we’d say designer air curtains in aesthetics—a low noise level, reduced weight, and an “EC” fan.

They are available in 3 sizes: 1 meter, 1.5 meters, and 2 meters long, and feature a heating power output of 2 kW to 15 kW depending on the model of air curtain in question.

With both vertical (wall installation) and horizontal mounting brackets (surface mounted air curtain installation or fitted off drop rods from the ceiling) options that allow adjustable airflow direction. The one installation mounting bracket set covers both options.

These air curtains are an ideal solution for commercial applications, including reception areas, hotel entrance halls, shops, retail outlets, restaurants, offices, service stations, theatres, car showrooms, and other public buildings, where customers prefer to be greeted with warm air upon entering.

EC Fans air curtains

The use of EC motor technology in various kinds of building projects has become increasingly popular in the HVAC sector for electric air curtain heaters. The explanation is simple:

• Traditional AC fan motors use 40–70% more energy than EC motors on air curtains.
• Compared to AC motors, EC motors have less slippage loss, which lowers expenses and boosts efficiency.
• EC fan motors can be directly connected to a BMS and use at least 40% less energy than AC fan motors.
• This ultimately means that EC fan air curtain models deliver lower running costs, which is important for any business.

Industrial electric heated air curtains

We do a full range of industrial electric air curtains suitable for all types of industrial doors; typically, they are used on up-and-over roller shutters (as shown in the picture below).  We can supply these industrial electric door curtains so that they can be fitted either horizontally across the top of the industrial door, with the air being blown downwards (again as pictured below), or vertically, blowing the air horizontally across the industrial door. These electric-heated industrial curtains can blow a maximum of 7.5 metres, be they vertically or horizontally installed (we can cover doors 14 metres wide when installed on both sides of the entrance); thus, most site requirements can be satisfied with this product range.

These industrial units are the ideal solution for loading bays, warehouses, aircraft hangars or factories that need an electric warm air curtain.

What is the difference between electric overdoor heaters and air curtains?

It’s important to understand the difference between the two.

Air curtain functionality

What it does

1. Creates a fast-moving powerful sheet of air that blows straight down across a doorway from the ceiling or horizontally when fitted on a wall installation with adjustable airflow direction
2. Acts as an invisible barrier to keep cold air out and warm air in (or vice versa for air-conditioned offices or shops, for example).
3. It aids in minimising draughts from the doorway, conserves energy and money, and enhances the control of climate temperature.

Primary purpose

1. The primary purpose is to maintain environmental separation by preventing heat loss when the door opens.
2. It can also prevent dust, insects, contaminants, and fumes from entering through the door or entrance.

Does it heat the room?

• Most provide little to no heat to the room itself.
• The main purpose is an air barrier, not space heating.

Over door heaters – what do they do?

What are overdoor heaters?

A small fan heater installed above a door.

Blows warm air into the room to provide effective heating for the immediate area.

Primary purpose of over door heaters

• Door heaters are for space heating — they warm the entrance area or small room.
• Over door heaters make the entrance or doorway feel more comfortable.

Does it create an air barrier?

No. Airflow is slower and aimed into the room with over door heaters, not down as a barrier.
