PROGreen Solutions CO2 Chiller

These one-of-a-kind chillers use R744 (CO2), a natural refrigerant that has zero impact on global warming or greenhouse gas emissions. Improved heat reclaim can also eliminate the need for fossil fuel sourced heating at a facility near the chiller. PROGreen Solutions CO2 chillers are an engineered long-term solution designed to be repaired, updated, and improved upon as technologies improve.
