Heatcraft 8145-20 Defrost Timer 240V

The Heatcraft 8145-20 Defrost Timer 240V is a spare component in commercial appliances to control defrost cycles in evaporator assemblies. It regulates the time and length of defrost periods, which provide to the efficiency of coils and the uniformity of cooling. Practically, it is fitted in refrigerated cases, walk-in coolers, and freezer systems where it is necessary to periodically defrost the system to avoid ice formation on the evaporator coils. Its coordinate system works by alternating between defrosting and cooling based on pre-determined schedules. It is commonly used in the circuit as a normal system operation and maintenance in food storage and commercial systems.
