The importance of quality walk in cooler and walk in freezer doors has been stressed on this blog before. After all, they are the gateway to your walk in cooler or freezer and are the one component that receives the most use. However, it could be argued that quality and well maintained walk in freezer doors are even more crucial than cooler doors. The following article will go on to explain why this is the case.
Anyone who is familiar with walk in coolers and walk in freezers knows the difference between the two. Walk in coolers are kept at temperatures above freezing (35 degrees being very common) and walk in freezers are kept at temperatures below freezing (-10 being very common). With these colder temperatures of the freezer comes more stress. As temperatures dip down well below freezing, it makes components of the walk in freezer more susceptible to breaking if the box wasn’t constructed with quality materials. This also holds true when taking the walk in freezer doors into consideration.
When analyzing some of the issues that can arise from having sub quality walk in freezer doors, the first that many can relate to is ice build up. If you’re experiencing ice build up around your walk in freezer door, it’s more than likely due to one of two things. 1) Your walk in freezer door isn’t sealing properly and cold air is escaping. Once this freezing cold air escapes and mixes with warm air condensation will form and freeze. This can lead to massive pieces of ice forming and literally being so heavy that they tear apart your door! 2) You are experiencing ice build up around the bottom or sides of your door. This can be caused by a faulty heater cable and or faulty threshold heater. It’s very important to have a heater cable installed around all four sides of your walk in freezer door if your unit has a insulated floor. If your walk in freezer doesn’t have an insulated floor and is sitting on an insulated concrete surface, than it’s very important to have a heater cable installed around three sides of your walk in freezer door frame and a threshold heater kit installed in the threshold area.
When purchasing walk in freezer doors, make sure you’re purchasing a door that is made using polyurethane insulation. Polyurethane will allow you to have a door that is both efficient and sturdy. Also, look for an embossed finish. An embossed finish is basically a metal finish (usually galvanized) that has a small dimpled pattern. This will help hide small dings and scratches that your walk in freezer doors will endure over time. Also, be sure that once you have your walk in freezer door, that you properly maintain it. This means periodically lubricating the hinges, visually inspecting the latch and strike for damage, oiling the door closer as necessary. If you purchase a quality walk in freezer door from American Cooler Technologies and provide proper maintenance, it should easily last the life of your unit!
