Description
The Carrier 06EA660165 Crankcase Heater is an inserted heating element used in compressor systems to maintain oil temperature inside the compressor housing during off-cycles in HVAC systems. It has an 11.5V supply and generates controlled heat to prevent refrigerant flow into the unit, which can reduce lubricating oil and cause incorrect compressor start-up conditions. It is particularly used in chillers and condensing systems. It supports compressor reliability by keeping internal conditions stable when the equipment is running, helping ensure proper lubrication and reducing startup stress in applications.
