Twelve-Seventeen Door (TSD-IG) Indirect Gas Heated Air Curtain

Indirect Gas

The Indirect Gas Fired air curtain works like your typical home gas furnace. The flame heats a tube, the air flows over the tube and the heated air is discharged. This air curtain will provide up to a 35 ̊F temperature rise at the threshold. Not only will this model prevent cold air from infiltrating the opening, it will help keep door hinges from freezing, keep the floor dry, help keep employees comfortable and promote safety and productivity.
