Most commonly recognized as a household cleaner, ammonia is also used as an industrial refrigerant in a variety of food and beverage processing plants around the country.

Ammonia refrigeration has been used in the food processing industry since the early 1900s. Most produce, meats and beverages in your home pass through a facility that at some point uses ammonia refrigeration. It is the most cost effective method of processing and storing frozen and unfrozen foods. Other possible uses include: post harvest cooling of fruits and vegetables, cooling of meat, poultry and fish and refrigeration in the beverage industry, particulary beer and wine.

How It Works

Hot untreated air enters the dryer and is cooled to 39oF (3.9oC) by the customer’s supplied ammonia. Moisture is dropped out of the air using a two stage, combination centrifugal separator and 3 micron cold coalescing filter and is expelled from the system via a zero air loss type demand drain. It is important to note that at no point throughout the drying process will the ammonia supply be in direct contact with the air side of the system.
