The Importance of Refrigeration Gaskets

Refrigeration gaskets are a very important part of your walk-in cooler or freezer’s performance. Under-performing gaskets could cost your business hundreds or thousands of dollars in energy bills. Gaskets are responsible for sealing your walk-in door and panels to stop any air infiltration. When your walk-in door is closed, the gasket keeps the cold air from escaping and more importantly warm air from entering your walk-in. When gaskets are not working properly, your refrigeration unit will have to work harder to keep its cold temperature – which in-turn generates higher energy bills and wear and tear on your equipment.

 
There are two different gaskets on your walk-in door that are both vital to your walk-in’s performance.
– The magnetic gasket is the thicker gasket attached to the door and helps to seal and keep the door closed.
– The wiper gasket is the thin single-dart gasket that helps seal the door to stop any outside air infiltration. Wiper gasket is located on the door and on the frame.

Periodically check door gaskets and door sweeps for wear and tear. Keep your gaskets performing longer by cleaning and removing any food, dirt, or debris build-up. It is suggested to include wiping down your gaskets during your daily cleaning routine.

 
Signs that your gaskets may need to be replaced:
– Step inside your walk-in and check for any light coming from around your door. If light comes through you know there is an opening in the gasket.
– Physically check to see if gaskets are ripped or torn.
– If your walk-in cooler gasket isn’t working properly, you may see sweating between the door and door jam. On a walk-in freezer, there may be ice or ice build-up.

 
When replacing your gasket, make sure to purchase the correct gasket for your brand of walk-in. Walk-in brands use different styles of gasket.
