Commercial Refrigeration: Maintenance Tips For Your Refrigeration Unit

Once they are installed, commercial refrigerators are relatively simple things to manage. Once the appliance has been connected to the mains power supply and the temperature control has been programmed, you can stock the refrigerator and listen as it quietly hums away in the corner of your commercial premises. While this is true, your commercial refrigeration unit can also benefit from some occasional love and attention to help to keep it in good working order. Below are some top tips that will help you to maintain your refrigeration unit.

Create Space Within the Refrigeration Compartment

It might be tempting to fill your commercial refrigeration unit to the brim. However, this can make it difficult for air to circulate to cool the unit. It is better to leave some space between the items being stored and the walls of the storage compartment. This will allow air to properly circulate around the unit and improve the efficiency of the appliance.

Cleaning the Coils

The coils of a commercial refrigeration unit allow hot vapour released from the condenser to meet cooler external air. This causes the vapour to condense into liquid form. The liquid is then pumped back into the refrigerator and where it absorbs any heat within the internal compartment, keeping it cold. Over time, dirt and dust can build up on these coils, which reduce their efficiency. This means your refrigerator has to work much harder in order to keep the internal compartments cool. You should wash the coils with warm water in order to remove any dirt or grime. 


Over time, particularly if it is set to a very low temperature, your refrigerator will develop a build-up of ice on its inside surfaces. Although you may have invested in a self-defrosting refrigeration unit, at the temperatures required for commercial food storage, even these types of refrigerators can become frosted over. A layer of ice is bad news for your refrigerator. It can affect your refrigerators ability to maintain a steady temperature and can cause the temperature in the unit to drop below the minimum levels you have specified. To avoid this problem, you should periodically defrost your refrigeration unit by removing any food stored in it, turning off the power supply and allowing the ice to melt.
