Choose from a range of refrigeration systems according to your temperature needs and facility size. For over 100 years, ammonia industrial refrigeration has been the backbone of food processing and cold storage distribution for the food and beverage industry. Plant employees described the vapors as too thick to see through. Ammonia refrigeration systems with 10,000 pounds or more of ammonia are a covered process subject to the requirements of the Process Safety Management Standard [29 CFR 1910.119].Many of these requirements are identified in this e-tool as possible controls and are useful as recommended practices whether or not the ammonia refrigeration system is a covered process. OSHA Standards for Ammonia Refrigeration Systems. •Hybrid Systems = 4 to 8 pounds per ton of refrigeration (2,200 to 4,400 lbs.) A “plan and specify” or a “design-build” arrangement can perform the refrigeration design. •Ammonia Charge for Systems used in cold storage (example 550 TR) •Central Systems = 20 pounds per ton of refrigeration (11,000 lbs.) pressure of tank + 350 mmWC 3 Range of operating pr. Refrigerant grade anhydrous ammonia is a clear, colorless gas or liquid and about 99.95% pure. "Ammonia is still the refrigerant of choice for large cold storage facilities," says Tom Cooper, president of Refrigeration Concepts, Inc., (RCI) Comstock Park, Michigan. Ammonia Refrigeration systems: We provide the turnkey solution of ammonia refrigeration system for application such as cold storage, process chillers for chemical industry, food & beverages processing, plastic industry, flake Ice machines, tube ice machines for concrete cooling and other applications. The project team developed a proposal to install a dual-temperature low-charge ammonia package refrigeration system, without the need for HFC refrigerants. 2 Normal Op. Packaging, section, product sorting workshop and alike places with many personnels prohibite to use ammonia direct evaporation refrigeration system. Refrigeration systems. Henningsen Cold Storage Co. (HCS) is a public refrigerated warehousing company based primarily in the Pacific Northwest. Ammonia refrigeration works much like Industrial Refrigeration systems using synthetic refrigerants, with the major exception being that it uses anhydrous ammonia as the refrigerant. Title: Cold Storage Warehouse improves efficiency with Ammonia Subject: A cold storage facility installed Vilter screw compressors to be able to comply with the latest environmental regulations and providing a cost effective system compared to variable speed drives. Ammonia transfer pumps Flare system Ammonia drain tank Read about company. Ammonia1 has been used as a refrigerant in industrial applications for more than 150 years.
