BHCI Series Aluminum Sill-Height Convection Heater

The sleek, flowing curved aluminum front cover and end caps of the BCHI offer a unique design for architectural applications. They are designed to fit under large windows to prevent cold down drafts. These heaters can provide total or supplemental heating for a variety of applications. The rugged design is built to withstand years of hard usage for your commercial application.

  • Easy to Install: Units may be mounted flush to the wall or directly to any floor surface. There are no screws on the front cover. Two rows of mounting holes on the back of the heater are spaced at 2 inch (51 mm) intervals for easy mounting. An electrical junction box is provided at each end of the unit for easy connection to the power wiring. To remove the cover, locate the locking tab at the bottom center of the heater. Rotate the tab counterclockwise with a tool through the air inlet and the cover can be withdrawn.

  • Choice of colors: Heaters can be matched to any decor. White or metallic charcoal are standard and a wide range of optional colors and custom finishes are available (see optional color selections on inside back cover).
