WHAT THE MANUFACTURER SAYS ABOUT THEIR CURRENT PRODUCT:
"The 7, 8, 9, 10 and 14HT series crankcase heaters are multi-voltage, in-well PTC devices. They are designed to eliminate compressor damage resulting from freon mixing with oil by creating a temperature differential between the oil and migrating freon. The in-well design provides excellent thermal coupling to the crankcase oil, minimizing heat loss to the environment. The multivoltage capability eliminates the costly need for inventorying additional heaters. Self-regulating PTC provides for power reduction with temperature rise, without the need for switch controls or thermostats. All 7, 8, 9, 10, & 14HT crankcase heaters are manufactured under statistical process control and are 100% tested at 125% of rated voltage for conformance to specifications.
Energy saving self-regulating PTC heaters - no thermostat required
Multivoltage capability / 240-600 Vac
Allows higher compressor E.E.R. s
Output increases as ambient decreases
Self compensates for voltage variations
