IT'S TIME TO CONSIDER A NATURAL SOLUTION.

The PROGreen Solutions team is focused on shifting away from synthetic, chemical-based refrigerants to natural solutions like CO2 which eliminates our impact on global warming without sacrificing operating efficiency.

CO2 AS A REFIGERANT

CO2, or R744, literally sets the benchmark that all other refrigerants are rated against when it comes to Global Warming Potential, carrying a GWP rating of 1- no impact on global warming.

To compare, 97% of the equipment produced by PRO in 2021 uses a refrigerant, R404A with a rated GWP of 3,900.

We use the same grade CO2 that our customers use to carbonate their Brite tanks. Our cost is currently about $2.00/lb, compared with $7.00-$15.00/lb for our common, chemical-based refrigerants.

The CO2 that we utilize is simply borrowed from the atmosphere versus the synthetic refrigerants that come at a tremendous expense and all with a future phase out date.

CO2 or R744, happens to have outstanding thermodynamic properties making it an excellent source of heat for fluids like wash water on a dairy farm.

Our current systems recover approximately 30% of the total heat rejected from our systems. With CO2 systems, we can easily operate above the trans critical point where there is no correlation between pressure and temperature. This allows us to increase recovery to more than 100% and even eliminate fossil fuel heating sources completely by generating hot water even during low cooling load and low ambient periods.

CO2 driven water heating systems can reliably deliver temperatures reaching 200 degrees F.

Factoring real-world conditions with increased heat recovery capacity, our engineers can make the case for natural refrigerants even in extreme climates like Bakersfield, CA.

CO2, or R744, has a high density, allowing us to utilize smaller diameter components than our current systems, and higher operating pressure gives us the ability to move a higher volume of refrigerant.

CO2, or R744, occurs in natures bio-chemical processes and is both NON-FLAMMABLE and NON-TOXIC.

To compare, 97% of the equipment produced by PRO in 2021utilized a chemical based refrigerant, R404A, with a rated GWP of 3,900. (Yes, that is 3,900 times more destructive to the environment than CO2!)

For PRO’s 30+ year, federal regulations have been continuously enacted to protect the environment. These efforts have helped reduce the number of high GWP systems, but they’ve also required manufacturers like PRO to redesign, retest, and re-certify their equipment for a competing list of low GWP (chemical-based) solutions, often with a compromise in efficiency and/or cooling capacity. CO2, or R744, as a refrigerant is the “baseline” for the Global Warming Potential (GWP) rating, it will never have a pending phase out date.

GLOBAL WARMING POTENTIAL

FUTURE PROOF

For PRO’s 30+ year, federal regulations have been continuously enacted to protect the environment.

Bill Jongsma Dairy

This is such an exciting time to be in the refrigeration industry, natural refrigerants are long overdue in the United States market. We can make a case for natural refrigerants, without a compromise in operating efficiencies, and deliver three times the heat recovery potential as our current equipment. Our goal, grow the PROGreen Line and the use of natural refrigerants, the plan to shift 25% of our production this direction in 2022.
