Carrier 06EA660168 Insertion Crankcase Heater 230V 180W 52″ Insert 73″ Leads

The Carrier 06EA660168 is an OEM insertion-type crankcase heater engineered to protect commercial compressors from refrigerant migration and liquid slugging during off-cycle periods. By maintaining the crankcase oil at an elevated temperature, this heater prevents refrigerant from mixing with the compressor lubricant — a leading cause of premature compressor failure.

Why Crankcase Heaters Matter

During extended off cycles — especially in cold ambient conditions — refrigerant can migrate into the compressor oil sump and dilute the lubricant. When the compressor starts, this refrigerant-oil mixture can cause oil foaming, loss of lubrication, and catastrophic compressor damage. The Carrier 06EA660168 crankcase heater eliminates this risk by keeping the oil warm and refrigerant-free between operating cycles, extending compressor life and reducing costly service calls.

Application

• Designed for use with compatible Carrier commercial compressors
• Ideal for rooftop units, chillers, and other commercial refrigeration and HVAC equipment
• Suitable for year-round use in variable ambient temperature environments
