  • Compressor lubricating oil heater control
    Patent number: 4066869
    Abstract: A control for selectively energizing a heater provided to raise the temperature of lubricating oil of a compressor employed in a refrigeration unit. The control includes a thermostatically operated switch provided to sense a temperature indicative of lubricating oil temperature. The switch connects the heater to a source of electrical energy when the sensed temperature falls below a predetermined value and the compressor is inoperable. When the compressor is operable, the heater is rendered inoperable irrespective of the sensed temperature.
