Introduction

The Thermo King truck refrigeration systems are two-piece nose/roof-mounted units. The compressor is powered from the vehicle engine via a belt. Refrigeration hoses and tubing are used to connect the unit to the compressor.

The Thermo King refrigeration units are designed for fresh and frozen applications on vans and small trucks.

The control circuits operate on 12V or 24VDC supplied by the truck batteries for over-the-road operation. The refrigeration system is protected by a high pressure cutout switch and a low pressure cutout switch.

The digital controller with a programmable microprocessor controls unit operation and quickly and accurately shows information on the display.

Compressor operation is controlled by the thermostat, energizing the clutch during engine operation.
