International Comfort Products NASA003CH Crankcase Heater - 208-230V 40W

The International Comfort Products NASA003CH crankcase heater is a belt-style compressor crankcase heater for air conditioning equipment. It warms the compressor crankcase during the off cycle. This helps keep the oil warm, reduces refrigerant migration, and supports proper compressor lubrication at startup.

Key Features:

• Crankcase heater, 208-230V
• 40W heater rating
• Fits compressor diameters of 4 1/2" to 5 1/2"
• Wraps around the compressor base below the oil level
• Comes with a clip to fasten it in place
• Wired across the open contactor contacts, so the heater is on when the contactor is de-energized

A crankcase heater helps protect the compressor from the effects of cold oil and refrigerant migration when the system sits idle.
