In this course, we look at the essential operation of an SB30-Series Thermo King fridge and explain how to start the unit, then change the set-point temperature and how to read the engine hours in the control panel.
The Thermo King SB30 series is arguably the most common refrigerated unit found on most fridge vans brands throughout the country. The fridge is a one-piece, self-contained, diesel-powered, air cooling/heating unit operating under the control of a SMART REEFER 3 (SR-3) programmable microprocessor controller. The unit mounts on the front of the trailer with the evaporator extending through an opening in the front wall, which can then have optional ducting to direct airflow.
The unit feature’s cooling and heating using a quiet running engine from the Thermo King TK486 engine family. The 4-cylinder TK486V is in the Tier 2 family of engines and is a water-cooled, direct injection diesel motor. Capable of running high engine speeds of 2600RPM in the SB330 units. The motor is coupled directly to the compressor on the Model 30. Belts transmit power to the unit fans, alternator and water pump.
The SB-230 and SB-330 feature the Thermo King X430L reciprocating compressor with 30.0 cubic inches (492 cm3) displacement.
