Description
Copeland 918-0056-05 Belt Type Crankcase Heater Overview
The Copeland 918-0056-05 is a belt-type crankcase heater engineered to protect refrigeration and air conditioning compressors from the damaging effects of refrigerant migration during off-cycle periods. By maintaining the crankcase oil at an elevated temperature, this heater prevents liquid refrigerant from mixing with the compressor oil — a leading cause of compressor failure on startup.
Key Features
- Belt-type design wraps securely around the compressor crankcase for maximum heat transfer
- Operating voltage: 480 Volts
- Power output: 120 Watts
- Genuine Copeland OEM replacement part (SKU: 918-0056-05)
- Helps prevent refrigerant migration and oil dilution during compressor off cycles
- Supports compressor longevity and reliable startup performance
- Compatible with Copeland compressor applications requiring 480V crankcase heating
Why Use a Crankcase Heater?
During extended off cycles, refrigerant can migrate into the compressor crankcase and mix with the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and accelerated wear on internal components. A properly rated crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free, ensuring a clean, safe startup every time.
