Description
The Trane HTR15175 is a 95-watt, 230-volt crankcase heater designed to protect compressor oil from refrigerant migration during off-cycle periods. By maintaining a consistent temperature in the compressor crankcase, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor damage and premature failure. At 18 inches in length, it is engineered to fit specific Trane compressor applications and delivers reliable, consistent heat output to keep your system running at peak performance.
Key Features
- Wattage: 95W for efficient, targeted crankcase warming
- Voltage: 230V for compatibility with standard commercial HVAC power supplies
- Length: 18 inches for proper fit on designated Trane compressor models
- Prevents refrigerant migration into compressor oil during off-cycle periods
- Reduces risk of compressor slugging and oil dilution at startup
- Genuine Trane OEM replacement part for reliable, manufacturer-approved performance
- Helps extend compressor service life and reduce costly downtime
Application
The HTR15175 crankcase heater is a direct OEM replacement part for select Trane HVAC systems. It is essential for installations in climates where ambient temperatures can drop significantly, causing refrigerant to migrate to the compressor sump. Proper crankcase heating at startup ensures oil viscosity is maintained and compressor components are protected from wear.
