When used in industrial-grade chillers, glycol is a coolant that functions as an antifreeze for specialized refrigeration and cooling systems. As opposed to ice or water only, a glycol chiller is especially useful for food processing applications, such as yogurt, ice cream, chocolate, and cold tables for salad bars and buffets. However, they’re also helpful in other environments, including breweries and dairy operations. The advantage lies in glycol’s ability to produce precise and consistent temperatures for optimal performance and efficiency.
