n today’s dairy, foods, and beverage industries, maintaining the correct temperature is extremely important to process integrity and to insure product quality and safety for the consumer. There is a world of difference between hot and lukewarm, cool and cold, and when specific temperatures are critical to a process, it better be right! Oftentimes, the best solution is a glycol chiller. What exactly is a glycol chiller?

A glycol chiller is basically a compact close-coupled factory manufactured refrigeration system that eliminates the need for field-installed refrigerant lines and components, by circulating foodgrade non-toxic propylene glycol to remove unwanted heat from a process, product, or fluid (like raw milk).

keep milk temperatures (and bacteria growth) under control. For larger producers or those moving to direct tanker load out, the glycol chiller is the best way to handle high volumes rapidly.

A manufacturer’s customer support and availability for advice is also critical to our success; that’s what we get from G&D.” Adding further, Steve Dennis of Rock Creek Refrigeration from Twin Falls, ID, shares his thoughts on his long-term business relationship with G&D. “I first reached out to G&D years ago when my client, Double A Dairy needed to replace an older chiller. I was met with knowledgeable service as we worked through the chilling equipment selection. That new chiller showed up onsite and exceeded our expectations on performance and

Tony Freeman, owner of Sunny Slope Dairy shared his insight: “In these days of rising product quality standards and reduced demand / pay prices, the ‘smart money’ goes directly to overall value when selecting any equipment.
