Door Type
When choosing the type of doors you want on your refrigerator, be sure to consider the location of entrances, doorways, and other equipment, as well as how wide the aisles are in your kitchen. Here are two types of reach-in fridge and freezer doors, and some key points to consider before making your decision.
Swing Doors
- The stay open feature makes loading and unloading inventory easier
- Easier to view all contents in the unit
- The traditional swing door is split into two sections
- Conserves energy and promotes more consistent internal temperatures
Door Material
Solid Door
- Easier to clean than glass
- More insulation than glass
- Superior energy efficiency
- Lose product visibility
Glass Door
- Better visibility prior to opening the door
- Reduced opening retains more cold air
- Less insulation than solid door
- Requires more frequent cleaning
Other Features to Consider
Many reach-ins come with various features to make operation or cleanup easy. Here are a few features that you may want to consider when purchasing a new reach-in refrigerator or freezer.
Removable Gaskets
Gaskets form the airtight seal around your refrigerator's door that keeps cold air locked inside. Some reach-in refrigerators feature an easily removable door gasket, to expedite cleaning and sanitizing.
Digital Thermostats
Many newer models of reach-in refrigerators and freezers are equipped with a digital thermostat. Because digital thermostats provide more accurate readouts, and make it easier to monitor and adjust temperatures, they normally lead to lower service costs and fewer maintenance calls.
Specification Line vs. Standard Duty
While all commercial refrigerators and freezers are designed with the demands of the busy food service operation in mind, Specification Line reach-in refrigerators and freezers represent a manufacturer's top-of-the-line offerings. A "Spec Line" product usually boasts more sophisticated temperature controllers, a wider variety of exterior and interior options, and other upgrades in design and construction features compared to a "standard duty" model. These models are often specified by consultants for institutional design projects.
Installation Considerations
Beyond the actual features of the fridge or freezer you plan to purchase, you also need to consider where and how you will install the unit.
- Measure door frames and hallways. Prior to purchasing the unit, measure the length and width of any door frames and hallways the unit will be going through to establish a plan for how you will get the unit into the room.
- Ensure the room you are installing the unit in is well ventilated. Most manufacturer's specification sheets or manuals will lay out any clearance guidelines for the back and sides of the unit. Not adhering to these guidelines can result in inefficient operation and service calls. You should also avoid installing units in exceptionally humid or dusty areas because these conditions can cause the unit to rust or the condenser coil to malfunction.
- Install the unit on a level surface. Once you have the unit in a well-ventilated room, install it on a level surface away from heat and moisture-generating equipment. Operating a reach-in in high ambient temperatures may cause the unit to breakdown, and in many cases, it will void the warranty.
- Ensure it has the proper power supply. As far as electrical concerns during installation, a reach-in refrigerator or freezer should be supplied by the right voltage according to the manufacturer's literature, and it should have its own dedicated electrical circuit. Refer to your equipment manual for best practices and any special considerations for your particular unit.
Compressor Location
Bottom Mounted Compressors
- Pulls in cooler air, making it ideal for hot environments
- Bottom shelves are higher, and easier to reach
- Compressor can become clogged with dust, flour, or grease from floor
- Reduces potential storage space
Top Mounted Compressors
- Pulls in warmer air, making it better for cooler environments
- Less likely to clog than bottom mounted compressors
- Does not take up any storage space
- Less accessible for cleaning and service
Commercial Refrigeration Maintenance Tips
The key to getting the longest possible lifespan out of your commercial fridge or freezer is performing regular cleaning and maintenance on it. If you make sure to regularly perform the following steps, you can greatly cut down on service calls and having to spend hundreds of dollars on repair parts.
Clean the Condenser Coil
Keep the condenser coil free of dirt, dust, and debris in order to keep it operating at an optimal level. Use a condenser coil cleaner in order to easily remove any build-up that has accumulated on the coils. You should clean your refrigerator coils once a month.
Clean the Fan Blades
Clean the fan blades and motor with a soft cloth. If it is necessary to wash the fan blades, cover the fan motor to prevent potential moisture damage.
Remove any Blockage of Airflow
It is important that the refrigeration system has unimpeded access to clean air in order to operate sufficiently. Be sure any debris or dust is removed from areas of air intake or exhaust. This should be done at least once a week.
Wash Door Gaskets
Door gaskets should be cleaned about once a week. Simply remove the door gasket from the frame of the door, soak it in warm water and soap for 30 minutes, then dry with a soft cloth and replace. Ensure gaskets are sealing properly once they are replaced.
Replace Worn Out or Damaged Parts
There are many refrigeration parts and accessories that are necessary for the proper functioning of your refrigerator. It is crucial to replace those parts when they are no longer functioning in order to avoid larger possible issues. Perform regular quality checks on parts such as fuses, bulbs, thermostats, and gaskets.

Self Contained vs Remote Refrigeration
Understanding the differences between self-contained and remote refrigeration is crucial when it comes to choosing the right refrigeration system for your commercial kitchen. Self-contained units keep both the refrigeration system and the storage compartment in a single piece of equipment, making them ideal for smaller spaces or mobile applications. On the other hand, remote refrigeration systems (most common for walk-in coolers) separate the compressor and condenser unit from the storage area, allowing for quieter operation and greater flexibility in design. Let's explore the key factors to consider when deciding between self-contained and remote refrigeration to help you make an educated decision for your kitchen layout and budget. Shop A
Refrigerants Explained
Refrigerants are crucial for commercial refrigeration systems, responsible for cooling and preserving perishable items. With refrigerant regulations phasing out ozone-depleting refrigerants, such as R-22, many businesses are transitioning to more environmentally friendly options. Understanding the different types of refrigerants available for commercial use can help you make an informed decision when it comes to replacing your refrigerator or freezer. Shop All Commercial Refrigerators What Is Refrigerant? Refrigerant is a cooling agent that absorbs heat and leaves cool air behind when passed through a compressor and evaporator.
