Description
The Trane HTR15181 6.5-inch Crankcase Heater prevents refrigerant migration and oil dilution inside compressor crankcases during system shutdown periods. Operating at 40/32 watts with 575/460-volt compatibility, the heater maintains controlled compressor temperature through continuous surface warming around the crankcase section. It is mounted directly onto compatible compressor housings in rooftop units, condensing equipment, and refrigeration-based HVAC systems to reduce liquid refrigerant accumulation before startup. Stable shaft heating assists compressor lubrication management, minimizes internal damage during cold operating conditions, and supports dependable compressor cycling within large capacity.
