Chameleon Vestibule Exception (CHA-HW) Recessed Hot Water Heated Air Curtain

Hot Water

The CHA-HWST air door features hot water or steam heat in an air curtain designed to be discreetly placed in the ceiling above a door. The low-profile CHA-HWST requires less mounting space, and the controls can be accessed without first needing to remove the hot water/steam coils. This innovative design cuts down on installation and service time. The CHA-HWST can be used as an exception for vestibules as it has been tested in accordance with the ANSI/AMCA 220 standard. The CHA-HWST is architect-approved as the air curtain is hidden from view while still providing the performance and benefits expected from a traditional air curtain.
