About the Absorption Refrigerator


Warehouse Appliance provides information for consumers in regards to purchasing an absorption refrigerator.
Warehouse Appliance helps consumers purchase and choose absorption refrigerators.

What is an Absorption Refrigerator?

What is an Absorption Refrigerator? It is exactly what the name implies. The unit refrigerates by absorbing the warm air from the interior and expelling it to the exterior. Within the gas refrigeration industry, this process is accomplished by using a sealed absorption system containing a solution mixture of ammonia, water, sodium chromate, and hydrogen. The mixture is boiled by a flame usually fueled by either propane gas or natural gas.

 The active ingredient is the ammonia which turns from liquid to vapor and back to a pure liquid again. This pure ammonia liquid absorbs the warm air through aluminum plates on the fridge back wall, freezer back wall, and freezer floor. This system uses no motors, compressors, or any moving parts. This is all accomplished by heat boiling the solution and it rising to the top of the sealed system where gravity takes over and allows the liquid to flow through the coil system at a rate determined by slight downward angles of the tubing.

The system is very simple in operation but very complicated in design. A very slight change in angle can alter performance and lower efficiency. A couple percentage difference in the solution ingredients will also change the gas refrigerator performance . Any weakness in a weld will shorten lifespan. All these factors must be correct in order to produce an efficient unit with top performance. Strict quality control is vital toward good production results.

At Warehouse Appliance, we rely on our many years of experience in using gas freezers and fridges, servicing gas refrigerators, and repairing gas fridges, and our warranty records to make the business decision of promoting the best brand. We choose the EZ Freeze brand.

We rate the EZ Freeze quality control as the best in the industry. EZ Freeze is the only company that produces the absorption system in house at the factory. No outside contracting is used in production. Over 50% of the production process is centered around quality checks within the production line of the product.  A high pressure flushing occurs immediately after the welding process is complete to remove any weld slag or foreign objects that may be inside of the coils. The absorption system is then baked in an oven to relieve stresses and reduce the risk of stress cracks during its lifespan. The oven baking process also aids in sterilization of the internals of the absorption unit prior to filling. Baking off the oils and impurities. Each unit is then pressurized and leak tested before installation in the cabinet. The EZ Freeze absorption units are all made on a jig and foamed in a mold and are interchangeable at anytime in it's life span with a new unit. This promotes consistency and reparability. It may seem excessive, but after all, this is the heart of the absorption refrigerator. It is also the most labor intensive part of production so it must be 100% before the unit ever gets to the consumer.

Further down the production line near completion, each unit is tested in the factory "Hot Room" which simulates a harsh operating environment with temperatures of 100 degrees Fahrenheit and high humidity levels. Each unit must pass well within the limits of good food keeping temperatures after this 16 hour torture test. The results are recorded on each refrigerator prior to packaging. No over company within this industry does this.

When asked about these strict quality control issues, EZ Freeze ownership replies "We realize that most of our fridges are used in remote areas. Hard to get to and from areas. It puts a great hardship on the consumer if there is a failure and we just don't want to see that happen."
