When looking for the refrigeration system parts, you must know the name of Thermo King. As a global leader in transport refrigeration, Thermo King specializes in innovative heating, air conditioning, and refrigeration systems specifically designed for trucks, trailers, buses, and more. This guide helps you know what the Thermo King part is, how many categories they have, and what their function is, so that you can choose the right Thermo King parts and keep your vehicle running smoothly.
Where Are Thermo King Systems Used?
You’ll find Thermo King systems on almost anything that needs to stay cold (or warm) on the move. This includes:
- Refrigerated Trucks and Trailers: The big “reefer” units on semi-trailers.
- Delivery Vans: Smaller units for last-mile delivery of groceries or pharmaceuticals.
- Shipping Containers: For moving temperature-sensitive goods by sea or rail.
- Buses and Trains: Their HVAC (Heating, Ventilation, and Air Conditioning) systems keep passengers comfortable.
They are also used in stationary applications like cold storage warehouses.
Main Types of Thermo King Parts
Thermo King parts are the replacement components used to repair and maintain Thermo King systems, can be divided into main categories based on the system they belong to. Here are the main categories of Thermo King parts you’ll encounter.
1. Reefer Unit Parts
These are for the large refrigeration units on trailers and truck bodies that cool the cargo. They are self-contained systems with their engine.
- Engine Components: Filters (oil, fuel, air), water pumps, fuel pumps, injectors, glow plugs, starters, and alternators.
- Refrigeration Circuit: Compressors (the heart of the system), clutches, condensers and evaporators (the coils that exchange heat), expansion valves, solenoids, and high/low-pressure hoses.
- Airflow Components: Belts (which drive the compressor and fans), condenser fans, and evaporator fans. Proper airflow is critical for performance.
2. APU Parts (Including TriPac Parts)
An APU (Auxiliary Power Unit) is a small, secondary unit mounted on a truck’s frame. Its primary job is to provide climate control and power to the cab without idling the main truck engine, saving fuel and reducing engine wear.
- Engine & Power: Small, efficient diesel engines, alternators for battery charging, inverters to supply 120V AC power, and starters.
- HVAC System: AC compressors, heater cores, blower motors, condensers, and climate control panels inside the cab.
- Exhaust System: Mufflers and exhaust pipes, which need replacement due to heat and corrosion.
3. Vehicle Powered & HVAC Parts
This category is for units that don’t have their own dedicated engine. They are common on smaller delivery vans and buses.
- Common Parts: Engine-mounted compressors, drive kits and belts, rooftop or nose-mount condenser/evaporator units, heater cores, and passenger-facing climate control systems.
4. Control Systems & Electronic Parts
These are the sophisticated electronics that monitor temperatures, control the engine and compressor, run diagnostics, and log data.
- Common Parts: Microprocessor controllers, display modules, temperature sensors, pressure sensors, wiring harnesses, and electronic throttle actuators. A single faulty sensor can prevent a unit from running correctly.
5. Structural, Fuel & Maintenance Parts
These are the parts needed for physical repairs and routine maintenance across all unit types.
- Structural: Doors, access panels, grilles, latches, and mounting frames.
- Fuel System: Fuel tanks, fuel caps, fuel sending units (for the level gauge), fuel lines, and lift pumps.
- General Maintenance: This is the most frequent list of purchases and includes all types of belts, filters, hoses, fittings, oil, and coolant.
How to Find the Right Part Number
This is the most important step for any “look up.” You can’t guess.
- Find the Data Plate: Every Thermo King unit has a metal plate or sticker on it. This plate contains the Model Number and Serial Number. It’s usually on the mainframe of the unit.
- Use Those Numbers: The model and serial number are your keys. Any parts supplier will need them to find the exact component that fits your specific unit. Different versions of the same model can use different parts.
Conclusion
Generally, for finding the right Thermo King parts, you only need to do two simple things: know the exact system you have and find its model and serial number. With this complete guide, I believe that you have a good command of Thermo King parts to get the right parts for restoring your vehicle and minimizing downtime.
