Premium air curtain

NHS Air Curtains has a Premium series of low-maintenance air curtains for optimum user convenience. The air curtains have a sleek and minimalist design and can be fitted in plain sight.

The air intake is hidden behind a beautifully designed front panel that – if fitted the other way around – can take in air from below. This makes it possible to fit an air curtain flush against the ceiling. The most popular colour for an air curtain is traffic white, or rather RAL9016. Upon request, we can supply air curtains in any RAL colour of your choice.

Easy installation

Horizontal air curtains are easy to mount with M8 stud fixings or wall brackets that can be ordered separately. Vertical air curtains are supplied with consoles for fixing to the floor or on top of each other. Due to the risk of tilting, it is important to anchor the top air curtain to the wall or the ceiling.

Heating and cooling methods

  • null

    Hot water

    Air curtains that are heated by hot water have a heat exchanger that is connected to the central-heating network. We equip air curtains with a heating battery as standard, which is suitable for hot water of 80/60ºC and 60/40ºC (W). Air curtains are also available with a heating battery for low temperatures of 45/35ºC (LW).

    For optimum energy savings it is always important to adjust your air curtains properly with your central-heating boiler, city or district heating, heat pump or other sources of sustainable energy. The hot-water air curtains are secured against loosening by metal plates around the 3/4″ connections.

    Our electric air curtains (E) automatically adjust the control of heat and ventilation. It goes without saying that these air curtains have a safety circuit.

    Direct expansion

    Air curtains for direct expansion (DX) are suitable for the refrigerant R410A. These air curtains operate as an evaporator with a stand-alone heat pump or integrated into a VRF climate-control system.

    Especially for application with direct expansion NHS has developed the Superior DX air curtain.

    Our air curtains that screen off cold areas such as cold stores do not have a heating battery (A).

Good to know!

An air curtain with a heat pump is the most energy-efficient heating method. It is approximately 73% more efficient than an air curtain with electric heating.

The energy costs of an electric air curtain are around 53% higher than those of an air curtain that works on the basis of hot water from a central-heating boiler.


Manual operation

With manual operation you select the speed of the airflow. However, there is a chance that your air curtain does not operate properly in line with the conditions at that time. The air that you have heated or cooled may still flow away through doors and entrances.

Standard functions:

  • Five settings for the airflow speed.
  • Three settings for the heating capacity of an electric air curtain.
  • Summer-winter function (230 V) with control by a magnetic valve or pump.
  • You can use one control to control several air curtains. Convenient for large and wide entrances where several air curtains are required.
  • Partial or full integration into a building-management system or retail scheme. For example, switch the air curtain on or off through the building-management system or operate it with a 0-10 V signal.

Automatic or semi-automatic

Do you want to be sure of the correct settings? You prefer not to worry about your air curtain? NHS Luchtgordijnen has developed an innovative control – automatic or semi-automatic depending on the accessories you choose. It is a complete control system, suitable for all types of air curtains – from hot water and electric to hybrid and unheated. Depending on your choice of air curtain and accessories, different additional functions are available.

Additional functions (accessories):

  • To be used with an outside temperature sensor. On the basis of the outside temperature, the control automatically determines the correct setting. An air curtain is only used when it is really necessary.
  • To be connected to a door contact or sensor, which ensures that an air curtain only works when the door is opened or when movement is detected. After an adjustable period of time, it is switched off automatically.
  • To be used with an integrated or external room thermostat. A water-heated air curtain requires a magnetic valve for this purpose. With automatic control of the heat supply and the room temperature, ensuring the room temperature remains constant.
  • Control with fully integrated control of heat pump and air curtain, in function of the chosen heat pump. This can be in our control or in the control of the heat-pump manufacturer.
  • Frost-protection thermostat in case of partial outside air intake to prevent the heating battery from freezing.
  • With a timer, the air curtain switches on or off automatically.
