About Us

We offer a wide range of services to all of our customers, both new and old. Some of what we offer includes, but is not limited to:





HistoryIn 1907, Louis Roser installed the first commercial refrigeration system west of the Mississippi River, here in Salt Lake City, Utah. From there, the Louis A. Roser Company was started. Since then, we have been going strong, providing excellent, high quality service to all of our customers.

HistoryThroughout the history of the company, we have made major innovations to the refrigeration industry. In 1960, our signature Liquid Freeze system was patented (U.S. Patent No. 2,920,462). This system allowed for a quick freeze of whole poultry products, eliminating the need for blast freezers and double-handling.

HistoryWe strive to build close relationships with our customers, which benefits everyone. Working closely with facility operators and owners, we have been able to help many customers become very successful. Today, we still focus on the same principles in helping our customers.






SafetyWe take pride in our safety record at the Louis A. Roser Company. We ensure that all our employees and our customers are safe, both on and off the job site. With so much experience in working with a hazardous material such as ammonia, we know what to expect in the worst case scenarios and come prepared every day.

Every year, we offer an Ammonia Safety & Emergency Response Training to anyone that would like to attend. This course covers all aspects of working with ammonia, including what to do in an emergency, and how to prevent accidents. This training course qualifies as the standard 8-hour refresher required by OSHA 29CFR 1910.120 for any ammonia refrigeration plant operator. Not only do our customers attended, but local authorities, such as inspectors and fire departments, are regulars to this annual event.
