For doors in every width and up to 3 metres tall
You can create an effective air curtain for any door width. The four length sizes are easy to combine. Generally we choose horizontal installation, but there are situations where a vertical air curtain is better solution, for really tall doors for example.
Installation in a flash
Both the horizontal and vertical Silent air curtains are easy to mount. Horizontal air curtains are mounted to the wall with M8 stud fixings or with brackets that can be ordered separately. You can fix the vertical air curtains to the floor or on top of each other with the supplied consoles. In connection with the risk of tilting it is important to anchor the top air curtain to the wall or the ceiling.
Heating and cooling methods
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.
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.
Our air curtains that screen off cold areas such as cold stores do not have a heating battery (A).
Air curtains with hybrid heating (H) are suitable when the temperature of the hot water is low compared to the required heating capacity. These air curtains have an electric heating element that automatically heats up the airflow to the required discharge temperature.
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.
Renewed interface with touch screen
A modern look and improved ease of use: those are the big advantages of the control panel of our air curtains. It gives you even easier access to familiar functionalities. Installation is also easier than ever, as is adjusting settings. The new interface is very complete and among the most user-friendly on the market.
Automatic and semi-automatic control
Do you want to be assured of the correct settings? And don’t have to worry about your air curtain? Then the innovative control of NHS Air Curtains offers a solution. You have the choice between automatic and semi-automatic control, depending on the additional functions you select. The big advantage over manual operation? The certainty of an optimal indoor climate and minimal energy consumption. After all, with manual operation you run the risk that the selected settings do not match the circumstances, so that the heated or cooled air still flows away through doors and entrances.
Our innovative control system is suitable for all types of air curtains. From hot water to electric air curtains and from hybrid to unheated and direct expansion air curtains.
Our air curtains are standard equipped with the following functions:
- Airflow speed selection (5 positions).
- Choice of heating power (with electric air curtain, 3 positions).
- Summer-winter function (230V) with solenoid valve or pump control.
- Possibility to control several air curtains with one control. Useful for large and wide entrances that require several air curtains.
- For air curtains with a filter, a timer is built in so that the user knows when the filter needs to be cleaned.
- Partial or full integration into a building management system or retail scheme. For example, you can switch an air curtain on or off via the building management system or operate it with a 0-10V signal.
