Frost Master

Designed specifically for defrosting industrial and large commercial refrigeration systems, the Frost Master® sequences solenoid valves and relays to provide quick and efficient defrosting of evaporator coils. Because of its SPDT relays and time adjustable defrost steps, this controller is suitable for almost every defrost application including: top and bottom feed unit coolers, blast freezer evaporators, and ice makers. 

Whether the evaporator uses hot gas, electricity, or water to defrost, this controller makes setting or changing defrost periods simple and easy. A very precise quartz time clock facilitates accurate setting of defrost start times. Time clocks include battery back-up in case of short term power failure to avoid any nuisance re-setting of clocks after power interruptions.
