A Walk in Cooler – What You Need to Know
A walk in cooler is a vital part of the food business because it keeps a wide variety of products cool and fresh. It also helps businesses meet legal requirements to keep items below 40 degrees Fahrenheit and prevent spoilage.
A Walk In Cooler: What You Need to Know
The first step in choosing a walk in cooler is figuring out what size box you need and how long you want to store your goods. This decision will vary depending on your business and the products you plan to store, but it’s important to be sure you can comfortably fit all of your items in one unit.
There are a few different types of walk in coolers that you can choose from. Some are top mount systems that bolt onto the ceiling of the walk-in and others are side mount systems that are installed on the sidewall.
Top-Mount: This type of walk in cooler system comes pre-assembled and includes a self-contained evaporator coil that is bolted to the ceiling of the unit. These units come with a number of standard features and can be customized to accommodate your needs.
These units are more expensive than side-mount systems, but they offer greater energy efficiency and flexibility. They can also be more aesthetically pleasing due to their flush-to-the-floor design.
A Condenser: This part of the cooler removes the heat from the evaporator to keep the product at a safe temperature for your customers and employees. Typically, a thermostat will set a temperature of 35 degrees and a compressor and a condenser fan will work together to push warm air out of the unit while bringing in cold air to cool down the food inside.
Another major component of a walk in cooler is the insulation foam. This foam is a dense material that sits between the metal “skin” of the walk-in. It’s designed to provide an air-tight seal and keep temperatures low in case the door is opened or closed by an employee.
Having the right insulation will help your unit stay cool for longer and prevent the need to run the compressor as often, which can save you money in the long run. It’s a good idea to look for units that feature high-quality insulation, such as R-25 or R-28.
The skin of a walk in cooler is made up of aluminum, stainless steel or galvanized steel that’s coated with polyurethane to create a protective shield against environmental factors and prevent temperature loss. The insulated skin is usually 4 inches thick to ensure that your cold items don’t get too hot or too cold, as well as to protect against any other possible damage from the elements.
Insulation is a must for any walk in cooler to keep your products chilled and fresh, while keeping down your energy bill as well. Some insulation materials are more effective than others, so be sure to check with your supplier before making a purchase.
