Description
The Paragon 8143-20 Defrost Control Timer is an electromechanical timer to manage automatic cycles in commercial refrigeration equipment. Operating on 208–240V, it initiates at preset intervals and terminates the cycle based on time, temperature, or pressure input. Mounted within control panels, it regulates compressor shutdown or heater activation to remove ice buildup from evaporator coils. Commonly used in walk-in freezers and refrigerators, this component plays a key role in maintaining system efficiency, preventing frost accumulation and ensuring consistent cooling performance across HVAC systems.
