Different Types Of Walk-In Unit Doors And How They Work

Walk-in appliances are an important commodity in restaurants, school cafeterias, grocery stores, and food manufacturing plants. Most commercial establishments that deal with food utilize both a walk-in refrigerator and a walk-in freezer. Each unit is comprised of important components that create a sealed compartment for food and beverages. The internal compartment temperature ranges between zero and 38 degrees Fahrenheit.

Walk-In Appliance Slide Doors

The commercial walk-in refrigerator featuring a slide door provides a cold compartment for all kinds of food and beverage products. The unit features one large slide door that flows smoothly from the left to the right and vice versa. The walk-in unit slide door utilizes an above-the-door track, track roller, hanger assembly, and header to deliver smooth operation. Each component plays an important role in the functionality of the slide door. The bottom of the door has a door snubber for added protection from accidental damage caused by contact. The snubber sustains a significant amount of damage when contact is made with boots and equipment. The replacement may be required every few years. A neoprene sweep gasket is installed on the bottom edge of the door to create a seal. The sweep gasket sustains damage every time the door is opened and closed. Like the bottom door snubber, the sweep gasket must also be replaced routinely. It is recommended to perform a routine inspection to ensure the sweep gasket is in full operation. Replace upon the first sign of damage to avoid temperature fluctuations due to abnormal airflow inside the interior compartment.

Walk-In Unit Appliance Swing Door

The walk-in unit utilizes one large or two swing doors to provide access to the interior compartment. The swing door is installed utilizing lower and upper hinges. Each hinge allows the door the swing freely from the left to the right and vice versa. A damaged door hinge is a common problem with walk-in appliances. This especially applies to commercial units. The first sign of a damaged hinge is a faulty operation. The door will not swing freely. Another sign of a damaged hinge is a sagging door. These signs warrant emergency repair because the interior compartment cannot possibly maintain the proper environment needed to prevent foodborne illnesses. Swing doors are installed with a PVC gasket that goes all the way around the interior side. When the door is closed, the gasket seals the interior compartment. No external air should enter the interior compartment. No internal air will escape the cold compartment when the gasket is fully sealed.
