The air curtains are HVAC devices that separate the indoor and outdoor environment by means of an optically non-interfering air stream. The air curtains are installed to save on heating costs of buildings where doors are frequently or constantly open. The air curtains create a thick air barrier and thus prevent the exchange of warm indoor air and cold air from outside, thus helping to reduce the energy consumption costs of heated areas. The air curtains are available without or with heating (water or electric).
The COR air curtains are used to reduce cold air penetration and reduce warm air leakage from buildings. The efficiency of the system increases or decreases depending on the type of curtains used and to the overall installation conditions in the building. The general effect of the air curtains is to reduce the heat losses due to the open door. The COR series curtains are designed for permanent installation above entrances and doors up to a height of 3 m, the minimum placement height is 1,8 m. The efficiency of the curtain depends on the pressure conditions in the door.
The air curtains are available with or without heating and are installed above the doors. The curtain must cover the entire width of the opening. The air is drawn in from the front of the air curtain and is exhaled downwards in order to shield the door opening and minimize heat losses. If it is necessary to cover a door opening with larger width, it is possible to use several curtains next to each other. Subatmospheric pressure in the building significantly reduces the efficiency of the air curtain, so it is necessary to ensure balanced ventilation! The air flow velocity and heating are regulated, depending on the type, in two or three stages on the controller.
The PA air curtains are designed for the entrance areas of shops, offices and industrial buildings. The air curtains create an air barrier that prevents the penetration of cold air into the interior space and thus maintain a pleasant climate inside.
The ADA air curtains are suitable for use in cold storage warehouses and generally in premises where cold air needs to be maintained. The advantage is the possibility to apply their resistance from -20 °C. The air curtains create an air barrier that prevents warm air from entering the refrigerated space. This leads to energy savings and thus saving on cooling costs. The ADA air curtains can be used to shield even wider entrances. For this purpose, the air curtains can be installed next to each other. The air curtains have suction in the front so they can be installed where there is less space above the entrance. The air curtains are standardly available with a 1,8 m power cable with plug, wall bracket, adjustable grille and built-in two-stage speed controller. The maximum recommended installation height is 2,5 m.

The stainless steel air curtains are equipped with an adjustable grille, automatic temperature control, two levels of regulation, three speed levels and two levels of heating power. Recommended installation height is 2,5 m.
The COR-FT / COR-FTW air curtains are used to reduce the penetration of cold air and the leakage of warm air from buildings. The COR FT and COR FTW are specially designed for installation in false ceilings. The overall effect of the air curtains is to reduce heat loss, which occurs due to open doors. The curtains are supplied with electric heating, without heating or with water heating - type FTW.
The AR air curtains are designed for concealed installation in suspended ceilings. The AR curtains have a low construction height, so they are installed where there is little space above the entrance door. The AR curtains are equipped with a built-in regulation and a remote control or have an integrated control board of the intelligent SIRe control system. Thanks to the SIRe regulation, the air curtains can become a fully automatic system, which itself will maintain the temperature depending on the ambient temperature, the frequency of door opening or time adjustment, etc.
