| 8HT & 9HT SERIES

Features

Introduction

• Energy saving self-regulating PTC heaters - no thermostat required

• Multi voltage capability / 240-600 Vac

• Solid state reliability

• Allows higher compressor E.E.R.’s

• Output increases as ambient decreases

• Self compensates for voltage variations

• PTC element for long life

• UL tested for:

- Temperature

- Aging/Endurance

- Humidity

- Stability

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 crankcase heaters are manufactured under statistical process control and are 100% tested at 125% of rated voltage for conformance to specifications.

The 8HT and 9HT 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 dierential between the oil and migrating freon.
