Climate Control (THS-ST) Steam Heated Air Curtain

Steam

The THS-ST is a steam-heated air curtain that installs directly into the ceiling, providing a heated curtain of air above doors with limited headroom. The THS improves comfort by creating a warm barrier of air that blocks cold, outside air from entering. It is ideal for buildings and facilities relying on steam-based heat.
