Description
The Carrier HT32TC905 is an OEM crankcase heater engineered to protect compressor integrity in Carrier HVAC systems. Crankcase heaters are a critical component in refrigeration and air conditioning equipment, preventing refrigerant from migrating into the compressor oil during off cycles — a condition that can lead to liquid slugging, oil dilution, and premature compressor failure.
Why Crankcase Heaters Matter
During extended off periods, especially in cold ambient conditions, refrigerant can condense and accumulate in the compressor crankcase. When the compressor restarts, this refrigerant-oil mixture can cause severe mechanical damage. The HT32TC905 maintains a safe crankcase temperature, ensuring the compressor is always ready for reliable start-up.
