The Different Types Of Walk-in Cooler and Freezer Doors

The door for your walk-in cooler or freezer is arguably the most vital piece of equipment when it comes to properly maintaining internal temperatures inside your unit. Your walk-in unit’s door is the seal between the outside and the items you are storing inside. Items being stored inside the unit rely on proper climate and temperature control, and the seal of your door is what ensures that the climate and temperature are being properly regulated. Since the door is the way in and out of the walk-in unit it is subject to excessive amounts of wear and tear, and different door styles are better suited for different situations for the walk-in unit. Here are some differences between walk-in doors and things to consider when choosing which door would be best for you.


Swing doors are a very common option for walk-in units, and rely on a combination of a rubber gasket seal along with a sweep at the bottom of the door to help seal the door, keeping the cool air inside the unit and preventing the warm outside air from entering. Hydraulic pumps on the door hinges are used to help open the door but more importantly to ensure that there is an air-tight seal when the door is fully closed. Due to the amount of parts required to ensure a proper air-tight seal with swinging doors it is important to regularly clean and check the door for any signs of wear-and-tear or damage that could degrade the air seal. 


The other popular walk-in cooler or freezer door style is the sliding door, which work by sliding all the way closed in order to create an air-tight seal. There are less moving parts required to ensure a proper seal with sliding doors. As long as there is no light leaking into the unit when the sliding door is closed then you can confidently assume that the door is sealing correctly. If you do see air leaking in you should get the door checked to find what is causing the light leak and repair it so that issues don’t arise. 


While a small amount of air leak may not seem like a big deal, they should not be ignored for too long. An improperly sealed door requires the walk-in unit components to work harder in order to regular the temperature, and this can lead to excessive wear-and-tear on the components causing them to need to be repaired or replaced. Other signs of a bad door seal could be ice or condensation build ups inside the walk-in, irregular temperature readings on the internal thermometer, and visual signs such as cracking and tears in the rubber door seal itself. If you feel there may be something wrong with the door or the seal you should contact a professional technician so they can come out and advise what the issue is and a solution.
