Description
The Watts 0831010 is a crankcase heater designed to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration during off-cycle periods. By maintaining a consistent warmth around the compressor crankcase, this heater prevents liquid refrigerant from mixing with compressor oil — a leading cause of compressor failure on startup.
Why Crankcase Heaters Matter
During extended off-cycles, refrigerant can migrate into the compressor crankcase and dissolve into the oil. When the compressor starts, this refrigerant-oil mixture can cause slugging, oil foaming, and premature bearing wear. Installing a crankcase heater is a proven preventive measure that extends compressor life and reduces costly service calls.
Key Features
- 59″ lead wire for flexible routing and easy installation in tight equipment spaces
- Designed to wrap around or mount directly to the compressor crankcase
- Maintains crankcase temperature to prevent refrigerant migration and oil dilution
- Helps protect compressor bearings and internal components on startup
- Compatible with a wide range of residential and light commercial refrigeration and HVAC compressors
- Durable construction built to withstand the demands of continuous HVAC service
Application
Ideal for use in air conditioning systems, heat pumps, refrigeration equipment, and any application where compressor protection during off-cycle periods is required. The generous 59″ lead length provides the flexibility needed for varied equipment configurations and panel routing.
