Trane HTR2047 Crankcase Heater
The Trane HTR2047 Crankcase Heater is a critical 120V, 150W component designed for industrial and commercial compressor protection. This heater maintains high oil temperatures to prevent harmful refrigerant migration and condensation within the crankcase during system off-cycles. By ensuring the oil remains at an optimal viscosity, it prevents liquid slugging and ensures immediate lubrication of bearings and rotors during startup, which is essential for maximizing HVAC system reliability.
Built for the rigors of field service, the HTR2047 features a durable construction that withstands the variable thermal expansion and environmental exposure typical of rooftop units and outdoor condensers. Techs should verify the 120V power supply before installation and ensure the heater is energized at least 24 hours prior to compressor startup to fully drive off any migrated refrigerant. This OEM replacement part is compatible with a wide range of Trane RTAC, RTAC, and CGAM series chillers and packaged units.
- Prevents Flooded Starts: Maintains oil temperature above the refrigerant saturation point to eliminate liquid slugging.
- High-Wattage Performance: Delivers 150W of steady heat for large-scale commercial compressors.
- Industrial Durability: Engineered to handle the heavy vibration and environmental conditions of high-tonnage HVAC applications.
- Direct Compatibility: Precise fit for Trane packaged rooftop air conditioners and industrial chillers.
Common Questions
How do I test if the HTR2047 is functioning?
With the power disconnected, use a multimeter to check for resistance (ohms) across the heater leads. An open circuit or "OL" reading typically indicates a failed heating element that requires replacement.
When should this heater be energized?
For maximum protection, the crankcase heater must be energized as long as the compressor is off, particularly when ambient temperatures drop. Trane specifies a 24-hour pre-heat period before the initial compressor start.
Can this heater cause a tripped circuit breaker?
Yes, if the internal insulation of the heater fails, it can create a direct short to ground. If you are troubleshooting a tripped breaker on the compressor circuit, the crankcase heater is a primary component to inspect.
