This heater has a power of 150 watts and a voltage of 120 volts and is suitable for equipment up to 4/3 horsepower. The one is 5” in length, 5” in breadth, and 2” in height and is portable and efficient. Crankcase heaters are essential for driving air conditioners and heat pumps to optimal performance as the compressor’s oil must circulate and remain warm. This minimizes the detriment and erosion created by refrigerant leakage into the compressor, thereby improving the unit's efficiency and durability.
