ATK/Thiokol

Magna, Utah

Year Completed: 2008/2009/2011

Scope: ATK is a major name in space and science, providing NASA with the solid-state rocket fuel for the space program. They use an ammonia refrigeration system to chill a brine solution, which is used in another part of their processing. In 2008 and 2009, LA Roser began upgrades to their system, including replacing the original upright compressors with the advanced screw compressors used now. In 2009 and 2011, ATK worked with LA Roser to upgrade the old, very large, shell-and-tube heat exchangers to the new, efficient plate-and-frame chillers. These only take up a small fraction of the space for the same capacity.

ATK is a major name in space and science, providing NASA with the solid-state rocket fuel for the space program. Louis A. Roser provides and services them with an ammonia refrigeration system to chill a brine solution, which is used in their processing method. Updates completed include a replacement of the original upright compressors with new, advanced screw compressors. ATK later worked with L. A. Roser to upgrade the old, very large, shell-and-tube heat exchangers to the new, efficient plate-and-frame chillers. These new chillers only take up a small fraction of the space for the same capacity.
