CAI/CASI Series Architectural Cabinet Convector & Architectural Sloped Top Cabinet Convector

The CAI/CASI convectors are designed to heat large commercial spaces. They provide large amounts of heat without the fan noise associated with unit heaters.

  • Installation Options: Units may be mounted to the wall, flush on the floor or on pedestals. CAI units can be fully recessed when the front warm air outlet option is used. These units are not for residential use in the United States.
  • Added Safety: The sloped-top cabinet on the CASI prevents objects from being set on top of the heater, which can restrict airflow and cause overheating.
  • Wall-to-Wall Installation: A smooth painted finish back plate is available so that the unit can be mounted against glass walls.
