US Patent No: 8388318

Hermetic crankcase heater

---

Abstract

---

A heater is provided inside a hermetic compressor to heat the fluid in an oil sump of the compressor. The heater can be substantially submerged in the fluid even at low fluid levels. The heater can raise the temperature of the fluid to a predetermined temperature to substantially maintain non-lubricant fluids in a gaseous state and prevent non-lubricant fluids from mixing with the lubricant in the sump. A feed through assembly in the compressor housing is used to supply power to both the compressor motor and the heater.
