Description

Copeland 918-0118-05 Bolt-On Crankcase Heater

The Copeland 918-0118-05 is a bolt-on type crankcase heater engineered to protect refrigeration and air conditioning compressors from 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 damage and premature failure.

Key Features

• Bolt-on mounting design for secure, reliable installation on compatible Copeland compressors
• Operating voltage: 120 Volts
• Wattage: 50 Watts
• Prevents refrigerant migration into compressor oil during off cycles
• Helps extend compressor service life and reduce maintenance costs
• Genuine Copeland OEM replacement part
• Direct-fit replacement for compatible Copeland compressor models

Why Use a Crankcase Heater?

During compressor off cycles — especially in cold ambient conditions — refrigerant can migrate into the crankcase and dilute the lubricating oil. When the compressor restarts, this refrigerant-oil mixture can cause slugging, oil foaming, and bearing damage. A properly functioning crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free, ensuring reliable startups and long-term compressor health.
