Dissecting Your Walk-In Cooler

Dissecting Your Walk-In Cooler

n order to keep your walk-in cooler functioning as it should, it is important to understand all of the parts and components that make up your unit. By knowing about the different parts of your cooler and how they work, you gain a better understanding of how the unit works as a whole, how to keep it running as it should, and why regular maintenance is so important.

Commercial Walk In Refrigerator Components


All walk-in coolers are equipped with an evaporator, which freezes moisture in the air and forms a protective barrier against heat transfer. When ice builds up on the coils of the evaporator, a defrost cycle runs to melt this ice and drain it from the system using a drain line.


A condenser works to remove heat from the unit, allowing you to maintain the cold temperatures needed for food storage. Heat from the condenser is vented outside of the unit, and fans help move the hot air through the vents.


The compressor works alongside other parts to add pressure to the refrigerant in the unit, and this refrigerant works to cool down the air by absorbing heat and then evaporating into a gas that flows back into the compressor.


Other important components of your walk-in cooler include a control panel that allows you to set the temperature, an insulated door that has a tight seal that keeps cold air in and hot air out, and wiring that allows the unit to function using electricity. A thermometer is also installed in a walk-in cooler to keep a constant measure of the temperature.

All of these parts work together to keep hot air out of the unit and to keep cool air in so that your food and other refrigerated items stay cold and do not spoil. It is very important that you regularly inspect these components just to make sure that everything is running smoothly. For example, looking to see if the fan is still running and isn’t dirty and that drainage lines are properly draining is something that you can do yourself. Read more in our previous post about ways you can keep your commercial refrigerator running well.

Other refrigeration system maintenance procedures need to be performed by a licensed professional. This includes a thorough inspection of all elements, including evaporator and condenser coils, fans, door seals, and gaskets. This should be done at least twice a year to ensure that all of the parts are working together to maintain the lower temperatures needed in your cooler while also keeping your energy costs down. This can also help you prevent expensive repairs or replacements when a major component fails due to lack of maintenance. Learn more in the previous post we wrote about how to pick the right professional when you need a commercial refrigeration mechanic.

Knowing about the components of your cooler helps you understand the importance of maintaining your equipment, and it can help you save money on the long-term. By keeping your parts in working order and well-maintained, you can increase the longevity of your unit and keep your energy costs as low as possible.
