Copeland 918-0009-00 Bolt-On Crankcase Heater, 120V, 65W

Description

Copeland 918-0009-00 Bolt-On Crankcase Heater Overview

The Copeland 918-0009-00 is a bolt-on 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 accumulating in the compressor oil, reducing the risk of compressor damage on startup and extending the service life of the unit.

Key Features

• Bolt-on mounting design for secure, reliable installation on compatible Copeland compressors
• Operating voltage: 120 Volts
• Power output: 65 Watts
• Prevents refrigerant migration into compressor crankcase oil during off cycles
• Helps protect compressor integrity and extend equipment service life
• Genuine Copeland OEM replacement part
• SKU: 918-0009-00

Application

This crankcase heater is designed for use with compatible Copeland compressors in residential and light commercial HVAC and refrigeration systems. It is particularly important in applications where ambient temperatures drop significantly, increasing the likelihood of refrigerant migration into the compressor oil sump.

Why Use a Crankcase Heater?

Refrigerant migration occurs when the compressor is off and refrigerant vapor travels to the cooler crankcase, dissolving into the lubricating oil. On startup, this mixture can cause oil foaming, loss of lubrication, and premature compressor failure. A properly functioning crankcase heater is a critical component in maintaining compressor reliability and system efficiency.
