Door heater for industrial hall gates
Air curtains, also referred to as door curtains, are devices that blow a controlled flow of air into a door space to form an air seal. The air curtain can be located above or on the side of the entrance door or gate. This seal separates two different environments and at the same time allows a smooth uninterrupted passage and view through a door, gate or other opening. Air curtains help retain heated or conditioned air and thus contribute significantly to energy savings and increase the personal comfort of people indoors.
