Danfoss 120Z5040 Crankcase Heater
The Danfoss 120Z5040 Crankcase Heater is a critical preventative maintenance component designed for scroll compressors and reciprocating units to mitigate liquid refrigerant migration during the off-cycle. This belt-type heater delivers 70 Watts at 240 Volts, ensuring sufficient oil temperature to prevent refrigerant dilution and subsequent bearing wash-out during cold starts. Engineered with a 6.5-inch diameter and 52-inch leads, this heater provides a secure, thermally efficient fit around the lower housing of the compressor. The stainless steel construction and rugged design are optimized for high-pressure HVACR environments where constant thermal cycling is expected. For contractors managing Danfoss Performer series compressors, maintaining proper crankcase oil temperature is vital for long-term reliability and volumetric efficiency. This surface-mount heater ensures that the lubricant maintains its viscosity, protecting internal components from premature wear caused by high-viscosity sludge or liquid foaming at startup.
- Oil Dilution Prevention: Eliminates refrigerant concentration in the sump to ensure superior lubrication during compressor startup.
- Precise Fitment: The 6.5" diameter belt design allows for maximum surface contact and efficient heat transfer to the oil reservoir.
- High-Temperature Durability: Constructed with industrial-grade materials to withstand the thermal demands of commercial refrigeration systems.
- Extended Lead Length: Features 52-inch leads for flexible wiring and integration into existing control panels or terminal boxes.
- Optimized Wattage: The 70W power output provides the ideal balance between energy consumption and effective heat dissipation.
Common Technical Questions
How does this heater prevent compressor failure?
By keeping the oil warmer than the rest of the system, it prevents the refrigerant from condensing into the oil, which avoids oil foaming and ensures the oil pump (if applicable) can deliver clean lubricant to the bearings immediately upon startup.
Can this heater be used on other compressor brands?
Yes, as long as the compressor housing diameter is 6.5 inches and the electrical system supports a 240V 70W load. Always verify the physical circumference before installation.
Is this heater intended for continuous operation?
Typically, crankcase heaters are wired to be energized whenever the compressor is in the off-cycle to maintain a constant temperature differential between the oil and the suction gas.
