We offer UK-wide service and breakdown cover for refrigerated trucks and vans, from single vehicles to fleets. We are independent and supply, install, maintain and repair all makes and types of transport refrigeration systems for diverse fresh, chilled and frozen goods.

Our services cover traditional transport refrigeration units powered by diesel generators to other systems such as FRIGOBLOCK, which are cleaner and use an alternator connected to the main truck engine.

We also offer helpful, expert advice, reflecting our strong customer service and years of engineering experience in keeping refrigerated transport businesses on the road.

Below are some common maintenance issues that can arise with refrigerated transport systems. Better awareness of these can prevent problems happening and keep your refrigerated fleet in excellent shape to serve you well.

Backed-up with one of our MWL service and repair plans, these tips will help keep your cold-chain business in good shape for the future.


Battery strength

Refrigeration units typically stop and start frequently and a battery has a limited number of cycles. A low-charge battery can cause a refrigeration unit to run despite the set point being reached to keep the battery in health. Communications and telematics equipment create extra loads on battery voltage, so be aware of battery health.

Absorbent Glass Mat (AGM) and Flooded Lead-Acid (FLA) batteries can be good choices for transport refrigeration units. Solar technology can be incorporated into AGMs to lengthen the battery life. FLA batteries typically last for 18-24 months.


Starters and alternators

The number of stops and starts made by a refrigeration unit each can affect these.

Upgrading to new, better alternators can significantly increase the life and performance of the alternator.


Software and sensors

Keep your software updated to ensure the refrigeration unit is running on the latest version. This will take advantage of any enhancements due to software updates. Also check sensor location and grades at regular intervals to ensure these are correct. Look for any signs of refrigerant leaks and carry out a refrigerant level check.


Other maintenance advice

Also remember to check air, oil and fuel filters, fluids and belts. Check the defrost drain hoses and flapper valves for any debris or dirt. Inspect wiring for any looseness, fraying or chaffing. Elsewhere, check doors and hardware and perform a full pre-trip check regularly.

Routine servicing of refrigeration units will extend each unit’s operational life and keep your cold chain business on the road.
