Description
The Lennox 12U71 Crankcase Heater 40W 240V is an refrigeration support component designed to maintain oil temperature within compressor assemblies during idle or low-load operating periods. Positioned around, or adjacent to the compressor crankcase it applies controlled heat to reduce refrigerant migration into the oil reservoir when the system is not actively running in HVAC systems. Commonly utilized in air conditioning, heat pumps the heater works alongside compressors refrigerant circuits, and electrical control system. it helps as a temperature maintenance element that contributes to proper compressor readiness during startup, and intermittent operating cycles.
