Trane HTR1226 Crankcase Heater

Ensuring the longevity of a compressor requires managing refrigerant migration during off-cycles, and the Trane HTR1226 Crankcase Heater is the industry-standard solution for high-voltage configurations. This insertion type crankcase heater is engineered for a 460-volt power supply, delivering a consistent 60-watt output to maintain oil temperature above the refrigerant's saturation point. With a precise 5/8" diameter, this heating element provides a secure fit for designated compressor wells, maximizing thermal transfer and preventing slugging or flooded starts. The unit features 7-inch leads, facilitating straightforward wiring for technicians in the field. Designed specifically for Trane and American Standard units, the HTR1226 heater is a critical component for HVAC compressor protection in commercial and industrial settings. Utilizing a high-grade heating element, it ensures reliable performance and oil viscosity management, which is essential for maintaining the mechanical integrity of scroll compressors and reciprocating units alike.

• Optimized Thermal Output: The 60-watt rating provides targeted heat to prevent liquid refrigerant from mixing with the compressor oil.
• Precision Fit: The 5/8" diameter ensures high-contact surface area for efficient heat dissipation within the insertion well.
• Direct OEM Compatibility: Engineered as an exact replacement for Trane and American Standard part number HTR1226.
• High-Voltage Reliability: 460V rating makes it suitable for heavy-duty commercial HVAC and refrigeration systems.

How do I verify if the HTR1226 will fit my compressor?
Confirm the insertion well diameter of your compressor is exactly 5/8". This heater is often found in 3-ton to 10-ton Trane packaged cooling units and heat pumps using 460V power.

Why are the 7-inch leads shorter than some universal heaters?
The HTR1226 is a specific OEM part designed for configurations where the power connection is in close proximity to the compressor base, reducing excess wire clutter within the cabinet.

Can this heater be used on 230V systems?
No, this unit is rated for 460V. Applying 230V will result in insufficient heat (approx. 15W), failing to protect the compressor from refrigerant migration and potentially leading to mechanical failure.
