When a fault occurs in your walk-in door seal several issues can arise which comprise the safety, efficiency and quality of your cooler or freezer.
In the case of a freezer, where temperatures are kept well below freezing to preserve food and medical products, issues with your door seal may allow for warmer external air to move through the seal, as this warmer air cools, due to the internal temperature of the freezer, it will form condensation, which can collect in the door seal. Over time this condensation will freeze to form ice. If this continues to build up it can cause significant damage to your walk-in door, reducing the efficiency and even potentially breaking the door completely.
Mould and Bacteria
The most common usage for walk-in coolers and freezers is to maintain the exact conditions which are required for the hygienic preservation of food and pharmaceutical products. But walk-in door seals can often trap food and dirt, which over time if not cleaned can lead to the growth of mould and the spread of bacteria compromising the products stored in your walk-in units.
Maintenance, Cleaning and Repair
