Johnson Controls has launched the FRICK HeatPAC Reciprocating Ammonia Heat Pump for food and beverage processing facilities. It recovers waste heat from ammonia refrigeration systems and transforms it into high-temperature hot water for processes like pasteurization, sanitation, and space heating. For typical food and beverage applications, it can be up to seven times more energy-efficient than a natural gas boiler, based on Johnson Controls internal modeling.

HeatPAC has a heating capacity range of 200 to 2,000 kilowatts while providing hot water temperatures from 130 to 190 degrees F. It includes a standard 4:1 turndown variable frequency drive that provides part-load efficiency and an ammonia charge as low as 87 pounds.
