The Bitzer compressor crankcase heater is a vital accessory used to prevent refrigerant migration and oil dilution during compressor standby periods. Specifically designed for Bitzer compressor models 4F, 6F, G, H, and J, the 140W, 220V crankcase heater ensures optimal performance and protection in refrigeration and HVAC systems.This heater works by gently warming the compressor's oil when the unit is off, preventing refrigerant from condensing in the crankcase. Without this heating element, refrigerant could mix with the oil, leading to poor lubrication, increased wear, and even compressor failure upon startup. The 140-watt capacity provides just the right amount of heat to maintain oil viscosity without excessive power consumption, making it both effective and energy efficient.At Real Enterprises, we supply high-quality crankcase heaters compatible with Bitzer models in the 4F, 6F, G, H, and J series. Designed for 220V systems, our heaters meet OEM standards, ensuring durability, precise fitment, and long-lasting protection. Whether for new installations or service replacements, these heaters are essential for extending compressor life and improving system reliability, especially in low ambient or standby conditions.
