Western Gateway Storage Co. in Ogden, Utah, became the first end user to install Evapco’s Evapcold low charge ammonia, packaged refrigeration system. The company installed two units in its new cold storage facility.

Evapcold was chosen for the project because of its reduced installation time when compared to a traditional central system (300 hours instead of 4,000 hours) and because its roof-mounted design saves floor space. In addition, the low charge ammonia system will reduce Western Gateway’s regulatory burden and compliance cost. While a centralized, stick-built system would have piped thousands of pounds of ammonia throughout the entire Western Gateway facility, the Evapcold system contains the ammonia in just two sites. It uses only 4 lb of ammonia per ton of refrigeration.

Though headquartered in Taneytown, Md., Evapco built the new low charge ammonia refrigeration systems for Western Gateway Storage at its facility in Greenup, Ill. Once constructed, the systems were shipped to Taneytown, where Evapco subjected the units to rigorous testing in its research and development laboratory. David Bornemeier, president of Western Gateway, along with his wife, Western Gateway’s CEO Becky Bornemeier, and their three children, were on hand at the Taneytown facility to see the equipment first-hand.

Once shipped to Ogden, the Evapcold systems were installed by Jack Gage and his team at Jack R. Gage Refrigeration. The units were mounted on the roof in six hours, and complete install took only a few weeks.

Successful startup of both Evapcold units occurred on June 17, and both units performed well under 100°F hot-start summer ambient conditions. The Evapcold units successfully pulled the warehouse temperature to a -10°F (-23°C) design temperature incrementally over a 10-day period without problems.

Following the successful startup, Bornemeier opted to test whether the Evapcold units could pull the cold storage facility to -20°F (-29°F) in the event that customers required an even colder temperature. The low charge ammonia refrigeration units easily pulled the building temperature down to -20°F and passed the test. For now, Western Gateway will operate the facility at the -10°F design room temperature.
