Danfoss named Pro Refrigeration Inc. as its 13th EnVisioneer of the Year. The Auburn, Wash.-based manufacturer and supplier of chillers for the industrial and beverage processing market used Danfoss components to develop its PROGreen CO₂ chiller system.

The PROGreen system was used at a California dairy farm. Since installation, the milk temperature has averaged 37.1°F (2.8°C), whereas their previous chiller was unable to cool below 40°F (4.4°C). As a result, the farm was able to earn a quality bonus from milk processors and see revenue increases in the range of $1,400 to $2,800 per day. The chiller also recovers the waste heat from the chiller system to heat the wash water, heating 3,000 gallons of well water per day from 70 F to 170 F and eliminating the need to use fossil fuels as a heating source.

Launched in 2010, the annual EnVisioneer of the Year award competition recognizes North American original equipment manufacturers, building owners, municipalities, contractors and end users that have introduced a new product, opened a new facility or invested in a building or system upgrade in the past 18 months using Danfoss products or solutions to realize significant energy and environmental savings. The award was presented to Pro Refrigeration on August 24 at its Mocksville, N.C., facility.
