Gas Door Air Heater
Door Air Heaters temper the sudden influx of cold air when an overhead door is open. To mix hot and cold air, it is necessary to create a highly turbulent condition directly in front of the door. The Gas Door Air Heater provides a high velocity blast of hot air to mix with the sudden influx of cold air.
