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

When many people think of refrigerator maintenance, the doors are oftentimes ignored. This is very unfortunate because walk-in refrigerator doors play an important role in the refrigeration process. A1 Dallas Commercial Refrigeration Repair Commercial establishments, such as convenience stores, supermarkets, and restaurants are required by law to store perishables in environments between 35 and 37 degrees and zero degrees Fahrenheit for frozen food to avoid spoilage. Every component that makes up the walk-in refrigerator is vital to the operational process. This includes the doors, which feature seals and hinges that will break down over time. Commercial walk-in refrigerators and freezers are in continuous use by employees. The constant use results in normal wear-and-tear that will eventually impact the interior environment. Once the temperature drops below the federal and state guidelines, the odds of food spoilage increase.

Walk-In Freezer Sliding Doors

Large commercial walk-in freezers and refrigerators are sometimes equipped with sliding doors. The sliding doors are designed to create a fully sealed environment between zero and 37 degrees Fahrenheit. Like swinging doors, sliding doors sustain significant wear and tear from normal use. Walk-in freezers with sliding doors are particularly found in food manufacturing plants, logistic companies, meat processing companies, and food distribution companies.

Signs Of Damaged Walk-In Refrigerator Sliding Doors

The first sign of damage is visible wear-and-tear. The seal around the door will begin to crack and break away. When part of the seal is missing, the interior temperature is guaranteed to drop. The damaged seal allows cold air to escape from the interior chamber and room temperature air to enter the interior chamber. It may also be possible to detect light shining through even when the doors are closed. It is recommended to utilize your hand to access cold air emitting from the interior chamber.

Walk-In Freezer Swing Doors

Walk-in freezer swing doors are designed to create help create a cold-controlled environment for meat and other perishables. As previously mentioned, doors are often overlooked during the inspection process. A skilled Heating, Ventilation, and Air Conditioning “HVAC” technician carefully assess each component, including the doors that make up the unit. It is recommended that businesses train their workers to perform routine walk-in freezer and refrigerator inspections. Delegate the task to a reliable worker each shift. If necessary, keep a log of the inspections. Note any damage detected during the assessment.

Signs Of Walk-In Freezer Door Hinge Damage

The door hinges also sustain a lot of damage day-in and day-out in commercial settings. The first sign of hinge damage is a sagging door. One door may hang slightly lower than the other door. Another sign of a damaged door hinge is poor functionality. The door may not shut properly. If the hinge is not repaired properly, the door will stop creating a full seal and eventually stop swinging.

Walk-In Freezer Inspection, Maintenance, And Care

Walk-in freezers and walk-in refrigerators play important roles in restaurants, grocery stores, pharmacies, wine shops, convenience stores, food manufacturing plants, ice cream shops, food processing plants, and bakeries. Routine maintenance is key to avoiding ing food spoilage. Even a slight drop in the temperature increases the risk of food spoilage. Inspect door seals, sweeps, and hinges, the refrigeration system, interior compartment, electrical components, and exterior. Businesses should train their workers to perform quick inspections with each use. Report all signs of damage to management.
