The Trane HTR15197 is a 200-volt crankcase heater rated at 90/100 watts, engineered to protect refrigeration and air conditioning compressors from refrigerant migration during off-cycle periods. By maintaining the compressor crankcase at an elevated temperature, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor damage and premature failure.
Key Features
- OEM Trane replacement crankcase heater for reliable, application-matched performance
- Operating voltage: 200V
- Wattage: 90/100W
- Prevents refrigerant migration into compressor oil during off cycles
- Helps extend compressor service life and reduce costly downtime
- Designed for straightforward installation as a direct OEM replacement
Why Crankcase Heaters Matter
Refrigerant migration occurs when the system is off and ambient temperatures drop, causing refrigerant vapor to condense in the compressor crankcase and dilute the lubricating oil. When the compressor restarts, this oil-refrigerant mixture can cause slugging, bearing wear, and catastrophic compressor failure. A properly functioning crankcase heater eliminates this risk by keeping the crankcase warm enough to drive off refrigerant.
Application
- Designed as a genuine Trane OEM replacement part
- Suitable for commercial and residential HVAC and refrigeration systems requiring a 200V crankcase heater
- Always verify compatibility with your specific Trane equipment model before ordering
