Autonics Temperature Controllers – TC3YF Refrigeration Temperature Controller

Refrigeration temperature controller TC3YF series is high reliability temperature controller to protect the object inside the chillers via compressor output so that compressor operation cycle and ON ratio can be set even if errors occurs. This series also prevents loss of frozen efficiency with defrost function to remove frozen ice or frost in the freezer, and increases the efficiency of frozen through various delay time setting. DIN W72×H36mm.
