When you have a commercial freezer, you will likely notice ice build-up at some point. This can be caused by several factors, including moisture or hot air entering the freezer. Another possible cause is clogged drain pipes. If the drain is clogged, water can collect near the drain and cause ice to build up.
Poor door sealing can also be to blame. The seal may not be sufficient to contain the warm air, which can cause ice to build up. Alternatively, the door may have slots or spaces that let warm air into the freezer. In any case, you should check the seal to make sure it is airtight.
Finally, ice build-up in the freezer can be dangerous. It can cause an unpleasant environment inside and outside the freezer and can affect food safety and quality. If this is not checked, frost can form on the coils, which can affect the operation of the entire device. To prevent this problem, ensure that the door is closed as much as possible.
The primary cause of ice build-up is usually warm and humid air. There is a good chance that the door has an old seal and is not sealing properly. If it is, you need to replace it or remove the blockage. Additionally, icing on the evaporator coil can be a sign of cooling problems. If you’re not sure what could be causing this problem, consider calling a professional to inspect the unit.
