THE ROLE OF OIL CHANGES IN REFRIGERATED TRUCK MAINTENANCE

Refrigerated trucks are working hard on our roads, and it’s our responsibility to ensure they have everything they need to perform.

There's a reason why the truck-repair industry was worth $6.4 bn in 2023— people are obviously avoiding preventative maintenance for their vehicles! A malfunctioning transport refrigeration unit is a big problem, and it always will happen right when you need it the least. A breakdown can mean more than just a delay — it can mean spoiled cargo and a dent in your profits.

Refrigerated truck maintenance is vital, and the oil change process is a big part of it. This simple but important task could end up saving you the headache of unexpected breakdowns and cargo catastrophes.

The Inner Workings of Your Transport Refrigeration System

The cooling coil (or the evaporator) is the frontline soldier against rising temperatures. It ensures that hot air in the chilled environment meets its match, shedding thermal energy and keeping things frosty.

The compressor circulates and compresses the internal cooling agent before it hits the next stop on the refrigeration rollercoaster — the condenser — where the cool-down happens. Here, the heated-up refrigerant gets the cold shoulder until it transforms from a sizzling vapor to a chilled-out liquid. Finally, the expansion device takes the chilledout liquid from the condenser, throws in a pressure drop, and makes it ready to hit the cooling coil again for another round of temperature-taming action.

All four players need some care to keep this refrigeration process going. Regular maintenance ensures your transport refrigeration unit stays in great condition, especially when you hit the road hard.

Maintaining Optimal Performance for Your Refrigeration Unit’s Compressor

Another type of oil needs to be considered before we get to the engine’s oil. Oil analysis across the board for your vehicle means better predictive maintenance. Compressor oil is crucial for the longevity and efficiency of your cooling powerhouse.
