Chameleon Vestibule Exception (CHA-E) In-Ceiling Electrically Heated Air Curtain

The electrically heated CHA-E air curtain mounts discretely into the ceiling to create a heated barrier of air that prevents cold outside air from entering a building. The CHA-E can be used as an exception for vestibules as it has been tested in accordance with the ANSI/AMCA 220 standard. The CHA-E utilizes a smaller, which requires less ceiling space for installation and operation. Maintenance of the CHA-E can be made via a hinged bottom panel and the controls are mounted to the motor plate, eliminating the need for an external control box. The CHA-E combines performance and aesthetics into a discreet, in-ceiling mounted air curtain.
