Please NOTICE: Unheated air curtains use the ambient air where it is located and sucks that in and blows it down to separate temperatures from (2) areas.(outside/inside, room to room, coolers and freezers)

Please make yourself aware of the TEMPERATURE RISE on the spec sheets for models. Also, the temperature rise noted is at 4 inches away from the nozzles. As the air continues down, it is cooling off at a rapid pace. With heated air curtains, steam or hot water units provide the best performance. †We only sell electric heated models with the LoPro Series and the Standard Series. Units above these models blow too much air over electric coils and are inefficient. †Steam or Hot Water Heat Only.
