PRO Refrigeration welcomes California dairy farmers and winemakers to Mocksville, NC, to observe production on the state-of-the-art PROGreen Solutions R744 (CO2) Chiller Systems.

MOCKSVILLE, N.C., July 8, 2022 /PRNewswire-PRWeb/ — Christopher Jongsma of South Creek Dairy in Pixley, CA, invited his grandfather, John Jongsma, to travel to North Carolina and check the status of his new chiller system. Chris continues the legacy of dairy farming that started in Friesland, Holland, 65 years ago milking 9 cows. Today John’s sons and grandsons have expanded the family business, climbing towards 20,000 cows served across the family’s farms. Now their sights are set on increased efficiency and environmentally conscious cooling.

Chris watched closely when the first PROGreen CO2-charged chiller system was installed at his uncle’s, Bill Jongsma, dairy in August of 2021. He is excited to get an identical system shipped to California for startup this fall with the help of San Joaquin Valley Dairy Equipment.

This new system will cool the milk for his 3,900-cow dairy farm while also taking over 100% of the water heating load across the farm. Matt Sa, of San Joaquin Valley Dairy Equipment also made the trip and completed training on the system.

“Dairy farming today is all about the numbers, and the CO2 Chiller System is a bigger investment upfront,” said Chris Jongsma, “our farm needs several thousand gallons of hot water each day to sanitize – the savings this system provides in natural gas alone will help justify the higher cost for the equipment.”

Joining the group was Pablo Polanco of Frogs Leap Winery. Frogs Leap has been on the leading edge of sustainability since their inception and relies on their 100 HP PROChiller, operating on R404a, for over 10 years. Pablo’s goal was to learn more about the PROGreen R744 System as their winery searches for answers to reach their industry-leading climate goals.

“We realize if we eliminate chemical refrigerants from our winery, we have a big opportunity to reduce our carbon footprint,” offered Polanco. “It is exciting to learn that CO2 can be used as a natural refrigerant.”

“Between Carbon Reduction and increased heat recovery, the list of justifications for an R744 System keeps increasing,” added Damon Reed, who leads the PROGreen Product Group at PRO, “It is so valuable to have long-term customers like Frogs Leap to challenge us with questions that many winemakers will also be asking soon. It is great to have him here.”
