Trane HTR15194 Crankcase Heater

The Trane HTR15194 Crankcase Heater is a rugged, belt type compressor heater designed to maintain critical oil temperatures and prevent refrigerant migration during the off-cycle. Engineered for heavy-duty commercial and residential applications, this HVAC replacement part operates at 460-480 Volts and delivers a consistent 90-100 Watts of thermal output. With its adjustable 9 1/2-12 inch diameter, it provides a precise wrap-around fit for a wide range of compressors, ensuring maximum heat transfer efficiency.

This OEM Trane heater features 74-inch leads constructed with 18 AWG stranded tin-plated copper and high-temperature 105°C PVC insulation. As a veteran-grade compressor crankcase heater, it is built to withstand the rigorous conditions of rooftop units and split systems. By keeping the lubricant warm, it prevents "slugging" on startup, protecting the internal valves and scrolls from premature failure. For technicians performing HVAC system maintenance, the HTR15194 offers a reliable, drop-in solution that meets the exact electrical specifications of the original equipment.

• Universal Compatibility: Adjustable belt design fits compressors ranging from 9.5 to 12 inches in diameter.
• Enhanced Durability: Stranded tin-plated copper leads and 600V rated insulation prevent electrical shorts in moisture-heavy environments.
• Optimized Performance: Maintains oil viscosity to ensure immediate lubrication upon compressor engagement.
• OEM Standards: Manufactured by Trane/American Standard to ensure precise wattage and voltage alignment with system controls.

What is the primary function of the HTR15194?
It prevents liquid refrigerant from mixing with the compressor oil when the unit is not running, which is essential for preventing compressor damage during cold starts.

Can this heater be used on a 575V system?
No, this specific model is rated for 460-480V. Using it on a higher voltage system will lead to immediate heater failure and potential electrical hazards.

How do I ensure a proper fit during installation?
The belt should be tightened snugly around the lower base of the compressor shell. Ensure the heating element is in direct contact with the metal to facilitate proper heat conduction.
