HTR15188 Trane Crankcase Heater 12-13" Dia - 22" Leads

Belt Type 480 Volts 150 Watts 12-13" Diameter 22" Leads Crankcase Heater

The Trane HTR15188 Crankcase Heater is an OEM‑spec wrap‑around compressor heater designed for Trane and American Standard HVAC systems. This heater prevents refrigerant from condensing in the compressor during off‑cycles, reducing the risk of slugging, hard starts, and premature compressor failure. The 12–13" diameter band fits standard residential and light‑commercial compressor shells, while the 22" leads provide flexible routing during installation.

Rated at 480 volts and 150 watts, this heater delivers consistent warming performance in cold or low‑ambient conditions. It is a direct replacement for systems requiring a 12–13" wrap‑style crankcase heater and is commonly used in heat pumps and straight‑cool condensing units.
