The CARRIER HT31AR200 is an insertion-type crankcase heater intended for HVAC systems. This heater operates at a voltage of one hundred twenty volts and draws two hundred watts of power. With a diameter of three-eighths of an inch and an insertion length of six inches, it is designed to fit seamlessly into HVAC compressor crankcases. The leads measure sixty-three inches and allow for flexible installation.
The heater maintains the temperature in the compressor's crankcase to prevent cold start issues. This function reduces the viscosity of oil during colder conditions, ensuring smooth starts and reliable performance.
