Description

The Delfield RF000072-S Defrost Timer functions as a fundamental element which manages cycles for commercial refrigeration systems. The timer runs on 120V power at 15 amps while its 6-hour frequency includes a 15-minute defrost period for efficient ice and frost control. The Air-O-Tronic technology from this device provides users with specific defrost cycle control which optimizes temperature management and extends food preservation capabilities. This timer works with multiple Delfield models such as the 402, 403, 406, 407, 6000XL and more to stop frost accumulation and decrease energy costs through shorter compressor operation.
