Crank Case Heater

Crank Case Heater Manufacturer in India

A crankcase heater is an electrical component installed in the compressor of an air conditioning system, heat pump, or chiller system. It is typically operational at all times, even when the system is not running, though it may be turned off by temperature sensors or set points when not required. The primary function of a crankcase heater is to prevent refrigerant migration and the mixing of refrigerant with crankcase oil when the unit is off. It also helps to prevent the condensation of refrigerant inside the compressor’s crankcase. By maintaining the refrigerant at a temperature higher than the coldest part of the system, the crankcase heater ensures that the oil and refrigerant do not mix or become diluted, which could affect system performance.

These heaters work by converting electricity into heat. The amount of heat produced depends on the resistance in the heater coil when voltage is applied. Crankcase heaters are essential for maintaining the efficiency and longevity of refrigeration and air conditioning systems.
