Ideal for commercial installations, this air curtain is very powerful! It prevents cold air from entering a building when doors are opened repetitively. Developed for intensity, we could not ignore style, which is why this heater is very nice to look at. Primarily designed for restaurant drive-thru services, this heater is not limited to that application, but perfect as well for commercial lobbies. For a capacity of more than 5 kW, multiple units may be installed side-by-side.
