Grasslin: Refrigeration Defrost Timer
June 26, 2006
The DTMV40 mechanical refrigeration defrost timer can be used to control the defrost function of various commercial refrigeration equipment. According to the manufacturer, it features a special moisture-resistant coating that makes it ideal for refrigeration applications where a certain amount of condensation might build up. The unit incorporates a voltage selection DIP switch to quickly change between 208/240 and 120 vac. The electrical rating has been increased to 40 amps. The timer's horsepower ratings are 1 hp at 120 vac on all terminals and 2 hp at 240 vac on all terminals. The heavy-duty NEMA 3R outdoor enclosure has an extra-large box lug terminal block that can accommodate two 8AWG wires per position. The defrost timer has a real-time clock face for quick, easy, and accurate setting with captive trippers on 15-minute defrost intervals.
