Commercial Refrigeration Door Seal Repair

Does Your Refrigeration Unit Have a Leaky Door Seal?

The primary goal of a tight seal is to keep air from escaping between the interior and outside of the unit. The seal, in addition to allowing air exchange, also prevents moisture from entering the device. If the moisture levels in walk-in freezers rise, ice might form on the machinery and foods inside.

When Should a Gasket on a Commercial Refrigerator or Freezer Be Replaced?

When you should replace your commercial refrigeration gasket is determined by a number of factors, including how frequently you open and close your unit.

The gasket serves as a seal between the door and the unit, so if you see cracks, other cosmetic damage, or separation from either part of the unit, it’s time to replace it. You must respond if you sense cold air or drafts around the door, or if you detect temperature variations inside the unit. If proper temperatures are not maintained, that escaping air can actually result in an increase in energy consumption and possibly damage your food.

In this scenario, make sure the unit is properly leveled first. A level surface is necessary not just for door operation but also for optimum unit operation.

Make sure you’re aware of these three issues with door seals:

Maintenance of Door Seals

The first step in ensuring that your walk-in cooler or freezer has a strong, air-tight seal is to inspect the door gasket for cracks, tears, or holes on a regular basis. Placing a thin piece of paper or a dollar bill between your door and the gasket is an easy technique to see if your door seal is faulty. There is a leak and your gasket needs to be repaired or replaced if your paper or currency easily slides out from between the door and the gasket. You have a strong and efficient seal if your paper or currency stays in place securely. To ensure that all sides of the gasket are working properly, perform this test all the way around the perimeter of your door.

Cleaning the Door Seal

Over time, door gasket can easily trap food, dirt, and debris. With food safety in mind, it’s critical to clean seals on a regular basis to avoid mold formation, which can spread and jeopardize inventory. Cleaning door gaskets is easy with soapy water and a simple nylon scour brush.

Repairs to Door Seals

If you find that your door seal has deteriorated, a hands-on approach may be necessary. Placing petroleum jelly on the flat surface of the gasket might temporarily repair minor adhesion difficulties. If you find that these simple fixes aren’t working, get a professional to come in and assess if you need a professional repair or a complete gasket replacement.

Well-maintained door seals save energy and money by reducing the amount of energy used by your walk-in. They help keep goods safe from mildew, ice, and excessive moisture. Working gaskets are easy to overlook, but frequent inspection and maintenance can help you avoid costly repairs and replacements. Check, clean, and repair your gaskets on a regular basis to guarantee that your walk-in coolers and freezers maintain a tight door seal at all times!
