Natural Refrigeration Takes Priority as Southern Distilling Company Expands

For their latest expansion, the distillery opted for the state-of-the-art PROGreen Solutions series of chiller systems. The PROGreen 100 HP Chiller System is the first model to utilize the environmentally friendly refrigerant R744 (CO2). With a Global Warming Potential (GWP) rating of 1, R744 sets the benchmark for sustainability. In stark contrast, PRO’s leading chemical option has a GWP rating over 1,000 times higher, measuring at 1273.

The advantages of the new system extend beyond environmental benefits; the PROGreen System also ensures enhanced cooling efficiency by effectively transferring more BTU/HR with reduced kW consumption. Moreover, it offers valuable heat recovery capabilities, enabling the distillery to repurpose waste heat, typically discharged into the environment, as the primary heat source for fulfilling their hot water requirements. Southern Distilling Company is committed to reducing its environmental footprint, and this strategic purchase represents a significant step towards realizing that goal.

“I really appreciate that our new PROChiller uses a refrigerant that will never be phased out, unlike the refrigerant used in our current chiller systems and other options we’ve considered,” provided Peter Barger, CEO of Southern Distilling.

“For the PROGreen system to also operate more efficiently and allow me to reduce my boiler load by almost 50%, this will change how distilleries are built in the future.” Jim VanderGiessen, CEO of PRO Refrigeration, added, “As leaders in the distilling industry, Southern Distilling is an ideal customer. They have high expectations that have challenged us to provide the most efficient, next-level cooling solutions. We can’t wait to get this new system online and operating.”

With the CEO’s enthusiasm and PRO Refrigeration’s confidence, the distillery eagerly anticipates the implementation of this cutting-edge system, further solidifying their position as pioneers in innovative cooling solutions.
