Description
The Trane HTR12899 is an OEM crankcase heater designed to protect compressor reliability in commercial and residential HVAC systems. Operating at 460 volts and 67 watts, this heater maintains compressor oil temperature during off-cycles, preventing refrigerant from migrating into and diluting the lubricating oil — a leading cause of compressor failure at startup.
How Crankcase Heaters Work
During compressor shutdown, refrigerant can migrate toward the crankcase and dissolve into the oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, foaming, and accelerated bearing wear. The HTR12899 continuously warms the crankcase, keeping oil viscosity stable and refrigerant in the vapor phase — ensuring clean, protected startups every time.
