Imagine this: your cooling system suddenly fails and your entire production process comes to a halt. What do you do? Quick and effective action is crucial to avoid prolonged interruptions. But what are the right steps to take when faced with a cooling system failure? More importantly, how can you prevent such failures?

What are your first steps in case of a cooling system failure?

When your cooling system fails unexpectedly, problem diagnosis is your first crucial step. Many failures are caused by insufficient flow of the cooling unit. This can result in a low-pressure failure, where the low-pressure switch activates when the evaporation temperature becomes too low. Possible causes you should check are:
1. Non-functioning evaporator fans, and
2. Excessive icing on the evaporator coil

In some cases, you may also face high-pressure failure. The high-pressure switch protects your system from excessive pressure that can lead to damage.

The key to problem prevention: regular maintenance

How can you prevent cooling system failures? The answer lies in regular and thorough maintenance. Preventive maintenance is not only essential for maintaining the functionality of your cooling system, but also offers significant benefits:

  • Increased energy efficiency

  • Lower operating costs

  • Extended life of your system

Are you aware of the legal obligations for cooling system maintenance?

EU Regulation No 517/2014 requires regular leakage checks depending on the Co2 equivalent and refrigerant fill quantity:

- 5-50 tonnes Co2 equivalent: annual check

- 50-500 tonnes Co2 equivalent: half-yearly check

- More than 500 tonnes of Co2 equivalent: quarterly check

By complying with these regulations, you not only ensure compliance with the law, but also the optimal performance of your refrigeration system.

What do you do when repairs take time? 

Even with the best maintenance, breakdowns can occur. What if your cooling system repairs take longer? Rental refrigeration offers a quick and flexible solution. Coolworld Rentals provides a wide range of rental refrigeration options:

  • Cold stores for storage purposes
