Causes of Icing Issues in Walk-in Freezers and How to Prevent Them

11 February 2021

Walk-in freezers have been useful in businesses that require storage of food products. Aside from storing food products, these specific spaces have also helped preserve the quality of the products thanks to their cooling capabilities. With walk-in freezers, business owners are expected to benefit from expandable storage capacity, improved accessibility, and efficient temperature control.

But just like other elements in commercial establishments, walk-in freezers can obtain issues that can hugely affect the entire operations of a business. One notable issue that walk-in freezers can acquire is the icing problem. Icing issues can drastically affect the cooling and storage functions of walk-in freezers, which is why business owners like you should know their causes as well as how to prevent them.

Causes of Icing Issues

There are many possible causes of icing issues in walk-in freezers. One known cause of icing issues is the entry of warm, humid air inside the walk-in freezers. Normally, the components of walk-in freezers have effective sealing that can prevent warm air from entering. However, if these components start to lose their sealing capabilities, then expect some build-up of ice inside the walk-in freezer. Some components that may have been defective are walk-in door, hinges, door closers, and gaskets.

Aside from faulty walk-in freezer components, warm, humid air can also enter the walk-in freezers if some employees have unintentionally left the door open for too long. Alternatively, warm air can also enter during the restocking process.

The presence of a faulty pressure relief port can also contribute to the build-up of ice inside the walk-in freezers. Heated pressure relief ports are designed to prevent the accumulation of pressure inside these freezers. Once the doors have become difficult to open, then these specific ports may have failed, contributing to the development of ice inside the walk-in freezers.

Other possible causes of icing issues in walk-in freezers include lack of proper insulation, fan delay relay failure, and clogged drain lines.

Prevent Icing Issues

Fortunately, icing issues can be prevented with simple steps. One great way of preventing icing issues is to conduct regular inspection and assessment. Checking the door hardware, gaskets, drains, insulation panels, and other significant components can help you identify if some of them are already faulty. Checking these components can also help you assess if there are already some serious build-up of ice. Any faulty components must then be repaired or replaced to effectively prevent icing issues.

Another great step in preventing icing issues is to install air curtains or vinyl strip curtains. The installation of these curtains can stop humid, warm air from entering the walk-in freezers. Running a defrost cycle regularly can likewise avoid icing problems, unnecessary repairs, and excessive energy expenses.
