Compressor Control
CODE: HT series


The 7HT, 8HT, 9HT, 10HT, 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 multi–voltage 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 7HT, 8HT, 9HT, 10HT, and 14HT crankcase heaters are manufactured under statistical process control and are 100% tested at 125% of rated voltage for conformance to specifications.
