Durable, dependable construction
Designed for durability in any climate, the weather-resistant cabinets are constructed of galvanized steel and bonderized, and all exterior panels are coated with a prepainted baked enamel finish. Thepaint finish is non-chalking, and is capable of withstanding ASTM (American Society for Testing and Materials) B117 500-hour Salt Spray Test. All internal cabinet panels are primed, permitting longer life and a more attractive appearance for the entire unit. In addition, all size 004-012 units are designed with a single, continuous top piece to eliminate any possible leaks. Totally enclosedoutdoor-fan motors and permanently lubricated bearings provide additional unit dependability. Patented state-of-the-art Chronotemp™ defrost system uses time and temperature to keep the outdoor coil frost-free for economical, dependable operation. The Chronotemp defrost board can be easily configured for defrost cycles every 30, 50, or 90 minutes.
