Heaters and thermostats

HRC Explosionproof Thermostats

HRC thermostats from Eaton's Crouse-Hinds Division are used for heavy duty line voltage to control fan coils, fans, motor starters, valves, contactors and circulator motors in heating and/or cooling systems.

Applications include specific hazardous atmospheres such as oil refineries, chemical plants, paint and varnish manufacturing plants, certain hazardous metal finishing areas, coal processing locations, granaries and grain processing plants.
