Crankcase Heaters

Built with a continuous sheath construction, our heaters provide full contact with the HVAC compressor housing, facilitating heat transfer. With a continuous sheath comes more mass, which allows the heater to operate in open air. They come in three varieties: single pass (standard design), double pass (for high wattage applications), and narrow double pass (for applications with limited space).

TUTCO’s Specialty Heater design allows the heater to snugly clasp the compressor housing to provide positive mechanical grip and highly-efficient heat transfer. The lower-mass design allows the most efficient transfer of heat directly to the crankcase well.

We stock standard sizes, individually boxed, that will fit most applications. We can ship in 5 days or less. For orders of more than 5 pieces, please call our Customer Service department.
