Maintenance Tips For Commercial Refrigeration Systems

 It doesn’t matter if the business is booming or slowing down; at some point, you’ll have to deal with an emergency involving commercial refrigeration. However, by doing routine maintenance in the lead-up before and throughout your busiest times of the year, you may avoid costly breakdowns and keep your customers and employees content.

Here are seven helpful reminders to keep in mind about the upkeep of business refrigeration. If you need to, include these into your routine to keep yourself well-organized and on top of any difficulties that may arise.

Wash the interior and outside thoroughly.

One of the main reasons we’re called to service commercial refrigerators and freezers is that the business or its employees should have cleaned the cooling units more often than the floors and other surfaces. Remove any stains or spills from the interior, and wipe off the outside to stop any moisture from getting inside and damaging the refrigerator’s working parts. It would be best if you were on the lookout for any puddles of water that need mopping up.

Additionally, you will need to clean the floor around the fridge. This will stop mold and germs from growing on your food and making it unsafe to eat. When you go on to the following step of the process, which is to clean the condenser coils, this will also assist you in keeping the dirt and dust under control.

Maintain routine cleaning of condenser coils.

Commercial refrigeration systems should have this part cleaned every six months at the absolute least. If you were wondering how often you must do this, the answer is whenever they become dirty. The usual suggestion is every six months, although this may shift to more or less frequently based on your individual needs.

This is why you should clear the freezer coils and keep an eye on the rest of the refrigeration system to ensure nothing is blocking it. In the event of an accumulation, the evaporator will have to exert more effort than necessary, delaying the cooling process. If the evaporator’s motor is under too much stress, it may be required to hire an expert to handle it.

Remove debris from drains and lines.

More giant commercial freezers and refrigerators are more prone to attract slime and sludge, which can lead to the equipment freezing up and stopping functioning. Most often, this muck accumulates in the plumbing and the drain trays. Sludge and moisture in these pans can produce an unpleasant odor if they overflow and pool in the kitchen. Additionally, if the tubing becomes clogged, the defrost system will overflow, leaking its contents all over the flooring.

You may avoid these issues by keeping the drains and tubes clean. At least once every month, give the pan a thorough cleaning with a vinegar solution or some warm water and soap. In addition, keep an eye on the piping every few months to ensure it isn’t getting clogged up. Soap and water can remove any calcium or water stains that have accumulated outside the hoses to avoid premature wear.

Check the gaskets on the refrigerator’s doors (seals)

Door gaskets or seals wear out and tear with repeated usage of a refrigerator, and this is especially true of older models. It does an excellent job of maintaining a comfortable temperature inside the conditioned area. If the gasket on your refrigerator has a tear or break, heated air might leak in and destroy your food. In addition, there is a risk of bacterial and fungal growth due to food waste in these old gaskets.

Checking the door gaskets on a commercial refrigerator once in a while is a good idea. Find any signs of wear and tear, and double-check that the doors seal properly on all sides. Mild soapy water is best for washing gaskets gently because this will assist remove any food particles without damaging the gaskets.

Ensure the evaporator coil is in good condition.

Much like the condenser coil, the evaporator coil plays a crucial role in your commercial refrigerators. This component, housed close to the system’s evaporator fan, is responsible for soaking up excess heat generated by hot air circulation.

Keeping this area tidy is also essential. Always ensure this coil is nice and tidy, and don’t stuff your fridge or freezer to capacity with warm foods. If the evaporator coil is not getting enough air, the temperature within the cabinet will increase, and there will be water leakage if the cabinet is not correctly sealed.

Make sure the ice maker is always clean.

Even if you have a separate ice machine, you must keep your industrial refrigerator clean. When left unattended for too long, the longer food sits, the more mold and germs grow, which is terrible for everyone’s health (even your clients!). So, you should clean the ice before using it since no one likes discovering filthy ice in their beverages.

We’ve laid out all the necessary procedures in detail in an earlier article on our site for this section. However, if you still need help with this process, there is no harm in hiring a professional expert to clean this section for you instead. They will be able to do it quickly and effectively.

You need to change the air filter.

Commercial refrigerators have filters, too, much like your central heating and cooling system. To avoid this, we stress maintaining a clean refrigerator and freezer. Cleaning this part is as easy as using the oil and dirt from the stovetop and oven.

Care for the refrigerator’s air filter using a strong sho vacuum to eliminate dust and other debris. In addition, a degreasing solution should be used to remove any accumulated grease. More information on how to decrease the filter safely is likely to be found in the device’s user manual.

The accumulation of dirt and oil may be damaging in and of itself, not to mention the additional problems it might create. Replace the air filter immediately if you find any cracks due to debris when degreasing.
