Warehouse Appliance supplies ammonia refrigerators that utilize this resource in an absorption system to help keep perishable goods cooler. Our selection of ammonia refrigerators are ideal for a number of applications, including off-grid living. This is due to their highly efficient cooling system, which relies on ammonia instead of electricity. This makes them far more reliable.
What Does the Ammonia Do in the Absorption System?
Ammonia refrigerators, also known as gas refrigerators, operate from an absorption system that use ammonia as the active key ingredient and are made specific as non-electric appliances. Typically, you will see these units as propane gas refrigerators in recreational vehicles.
Ammonia is the key ingredient among four total ingredients within the cooling unit, also referred to as the absorption system. Water is the other liquid ingredient. Sodium Chromate is a powder substance that acts as an anti corrosive. This combats the highly corrosive ammonia. The fourth ingredient is hydrogen gas, which pressurizes the system to over 300 PSI. This is also true for ammonia freezers.
Another common question with ammonia and gas refrigerators we encounter at Warehouse Appliance is, “Will freezing temperatures affect the cooling unit since it is filled with liquid?” The answer is no. The liquid in the cooling unit is pressurized by hydrogen gas, which protects the liquid from freezing. The absorption system can be in use or just static in sub freezing temperatures without adverse effects.
With all 4 ingredients mixed together, the color is a bright yellow/green, which is the original color of sodium chromate. This color aids in leak detection. Either in wet form or dry state, the bright yellow/green color showing anywhere on the cooling unit coils will signal a leak.
The other tell tale sign of a leak is the smell of ammonia. Ammonia has a very strong odor and is sometimes used in cleaning agents. It can literally take your breath away. In high doses, it can be dangerous. For the most part, a propane-powered refrigerator is considered safe, which is why many have been in continuous use – in some cases for over 60 years.
