Defrost Timer Control
Apply precision timing to your commercial defrosting schedules and keep evaporators free of frost with a defrost timer control (AKA universal defrost timer or UDT). These motor-driven clocks control the electrical current flowing to your compressor. They defrost heating elements by switching the current on and off at preset intervals, essentially creating a defrost cycle. These adaptive defrost controls vary by amps, voltage, maximum on/off schedules and other considerations.
