Factory-Assembled, Low Charge Industrial Ammonia Refrigeration System Debuts at IIAREvapco Inc. introduced a factory-assembled, low-charge ammonia refrigeration system that requires just 2.5 to 3 pounds of ammonia per ton of refrigeration at the 2015 IIAR Conference and Exposition.

Consisting of a factory-assembled, self-contained ammonia refrigeration rooftop system designed to ship in one- or two-piece modules, the Evapcold product also offers plug-and-play installation. The Taneytown, Md.-based refrigeration systems maker credits the design with faster startups that require less on-site labor than field-built alternatives. The company also points to design innovations in heat transfer technology, energy efficiency and microprocessor control for reliable low-charge operation.

According to Evapco, the new packaged refrigeration system delivers a cost-effective ammonia refrigeration system for retrofit applications, building expansions and new facilities while complying with increasing local and federal regulations for safe ammonia use and meaningful refrigerant charge reduction.

“With demand for ammonia and other natural refrigerants still on the rise, increasing regulatory pressure continues to adversely impact owners of ammonia refrigeration systems,” said Kurt Liebendorfer, vice president of Evapco.

Evapco is demonstrating the Evapcold packaged refrigeration system from its booth at the annual meeting of the International Institute of Ammonia Refrigeration in San Diego.
