Ammonia Refrigeration: Safety, Options, Uses & Opportunities


This presentation shall first addresses some of the properties and safety issues for anhydrous ammonia. Then briefly reviews optional system approaches: Single stage versus Two stage and the three primary types of systems: Direct Expansion, Liquid Recirculation, and Flooded. Example of the use of these types of system will be presented. Concluding with opportunities in the ammonia refrigeration field.


From grade school through college Kem worked in a family owned refrigeration construction business based in Seattle, Washington with customers in the seafood, dairy, meat, and fruit and vegetable industries. After graduating from the University of Washington in 1978 with a B.S. in Mechanical Engineering he moved to Yakima, Washington working as V.P. of Refrigeration for Food Plant Engineering. In 1999 he returned to refrigeration construction as V.P. of Engineering for Doubl-Kold an industrial refrigeration contractor that does a large amount of work in the fruit storage industry, as well as design and construction in the seafood industry. He has been involved in the design and construction of industrial refrigeration systems throughout the continental U.S., Alaska, and in Central and South America. Kem also assists companies with OSHA – PSM and EPA RPM regulations specifically for ammonia systems.

Kem is actively involved in the International Institute of Ammonia Refrigeration (IIAR) Safety Committee helping in the development of many bulletins, posters, and videos as well as participating in the updating of many IIAR standards. He served as Chairman of the IIAR Safety Committee from 2006 to 2012. He also serves as a voting member of the IIAR Code Committee. He also served on the IIAR Board of Directors from 2009 to 2014. Kem is an instructor for hazard material technicians for dealing specifically with anhydrous ammonia since 1999.
