Daisy Brands, a Garland, Texas-based sour cream manufacturer, recently opened a plant in Casa Grande, Ariz. The company utilized components from Danfoss’s Flexline™ family of motor control valves and control stations to maintain proper refrigeration control.
“Making sour cream requires close temperature control to maintain quality,” said Tom Cooper, president of Refrigeration Concepts Inc. of Comstock Park, Mich., which installed the equipment. The Arizona site consisted of an ammonia refrigeration system producing chilled water to vats, silos, and the supply evaporator coils in the storage area. Circulation of the refrigerant is controlled by valves assembled in valve trains, which open and close to regulate the flow from the compressors to the heat exchangers, evaporator coils, and condensers, stated a report from Danfoss.
