The Different Types of Walk-In Cooler Doors

What stands between your refrigerated inventory and the outside world is your cooler door. Walk-in cooler doors require regular inspections to ensure they aren’t the victim of wear and tear from customers and employees.  Understanding the types of walk-in doors will help you ensure that your doors are getting proper maintenance and repair so that your walk-in coolers are running strong.

Slide doors are a common option for walk-in refrigerators and coolers. They work by sliding all the way closed to properly seal in the cold air. With sliding doors, you can ensure that they are properly sealing when there is no light shining through when the door is closed. Light around the edges of a closed door means there is a possible air leak. While a leak may not seem like a big deal, the outside air that leaks in could potentially damage your cooler and cause the refrigeration components to work overtime to ensure proper cooling, causing excess wear and tear on the components.

Swinging doors are another alternative for walk-in coolers. Unlike sliding doors, swinging doors use a sweep at the bottom of the door to help prevent outside air from entering the walk-in cooler and to secure the air seal. Since the door sweep plays such a crucial role in the regulation of temperature inside the walk-in unit, it requires regular maintenance just like any other part of the cooler. Swinging doors use hydraulic pumps for opening and closing of the doors that helps secure the air seal by ensuring the swing door is properly closed and sealed.

Walk-in cooler and freezer doors may be opened and closed continuously.  As such, condensation may form and ice can build up. To prevent this, freezer doors are built with a heater wire element.  This self-regulating cable prevents ice formation around the door frame. As such, do not tamper with the bottom door threshold that houses the heater wire.
