Large industrial refrigeration systems often utilize ammonia systems to keep the product cold, fresh and safe. The benefits of ammonia refrigeration are undeniable.

Factory-assembled, low charge ammonia refrigeration system requires much less refrigerant charge than that associated with traditional field-built systems. 

Among the list of refrigerants used in modern refrigeration applications, ammonia — known as chemical element NH₃, or as refrigerant R717 — is one of the few that has remained a viable option since first being introduced in the 1930s.

In the first part of this two-part article series (“The Regulatory Environment and the Importance of Reducing Charge in Cold Storage,” January/February 2016, p. 8 or www.process-cooling.com/Chapp-part1), I looked at the regulatory environment in the United States and the importance of reducing the charge of ammonia used in cold storage facilities and other refrigeration systems.

The environmental advantages of CO₂ — and how it has helped secured a position as a leading option for future refrigeration systems — are the focus of educational sessions at ATMOsphere America 2015.

Factory-assembled, low-charge ammonia refrigeration system requires 2.5 to 3.0 lb of ammonia per ton of refrigeration for an entire system, which is a fraction of the refrigerant charge associated with traditional field-built systems.
