Refrigeration Gaskets for Walk-In Coolers

In order to have a properly functioning walk-in cooler or freezer you need proper air seals to keep air inside the unit. The walk-in panels and doors are able to properly seal in air and prevent outside air infiltration due to rubber gaskets. The rubber gaskets prevent cold air from escaping when the walk-in door is closed, and is absolutely crucial to a properly functioning walk-in cooler or freezer. When a rubber gasket is not sealing properly it can cause a myriad of problems. The cooling elements will generally need to work harder to meet the temperature requirements of the thermostat, leading to an increase in your electricity bill and putting your cooling elements at risk of damage due to having to run overtime and extra hard in order to maintain cooling temperatures.In order to have a properly functioning walk-in cooler or freezer you need proper air seals to keep air inside the unit.

A walk-in cooler or freezer door uses two different kinds of gaskets - a magnetic gasket and a wiper gasket. 

• Magnetic Gasket - this is the thicker gasket that is attached to the door to help seal and keep the door closed. • Wiper Gasket - this gasket is the a thin gasket that sits behind the magnetic gasket on the door and on the door frame. This gasket also helps to seal the door and stop outside air infiltration.
If you notice an uptick in your electricity bill or start to hear noises that may indicate that the cooling elements in your cooler or freezer are working more than usual you should check the gaskets for any signs of damage. Here are a few things to look out for:

• Step inside the cooler and close the door, and then check the seal around the door to see if any light is able to enter the cooler. If there is visible light that means that there is some sort of damage, such as a tear in the gasket, that is allowing light to enter the cooler. • Look over the gaskets to see if there is any visible signs of damage, such as a rip or tear in the rubber gasket.  • Open the walk-in cooler and check the door seals for any signs of moisture. This ‘sweating’ occurs between the door and the door jam when there is a gasket tear, or in the case fo a walk-in freezer it may appear as ice or ice buildup. 

If you notice any signs of damage you need to replace the door gasket as soon as you can. Not only can a gasket leak cost you hundreds, if not thousands of dollars on your electricity bill but it can also cause heavy damage to the cooling elements of the cooler or freezer if left untreated for too long.
