Eco2Energy uses natural CO₂ refrigerant across all hot water and cooling systems. It’s efficient, widely available, and delivers high performance without the risks tied to synthetic refrigerants. For farmers, that means lower running costs, better reliability, and confidence your system won’t be affected by future phase‑outs.
But it also means something even more important: protecting milk quality.
Consistent hot water is essential. If your plant or silo wash doesn’t reach the right temperature, you risk leaving behind residues or bacteria. Reliable hot water isn’t a nice‑to‑have, it safeguards your milk quality. That’s good news for your dairy company and your bottom line!
For decades, dairy hot water and cooling systems relied on synthetic refrigerants, especially the 400‑series gases (R404A, R407C, R410A). These refrigerants have very high global warming potential (GWP) and are now being phased down globally.
Supply is tightening as global phasedown accelerates
Affecting every service call on older systems
The maths will stop working as costs climb
This is a long-term structural change, not a temporary blip
This is already affecting farmers through higher service costs and limited availability.
CO₂ has a GWP of 1 – the lowest possible. It’s not part of any phase‑down programme, and it’s not going anywhere.
Because CO₂ isn’t being phased out, you avoid the rising costs and uncertainty tied to synthetic gases. Your system stays serviceable and economical for its full lifespan.
CO₂ is one of the only refrigerants that can reliably produce 85°C hot water, even in cold weather. This directly supports milk quality and compliance.
CO₂ moves heat quickly and efficiently, making it ideal for fast, stable milk cooling and consistent glycol temperatures.
CO₂ systems convert 1 kW of electricity into up to 3.9 kW of heat output, reducing energy use for both hot water and cooling.
CO₂ is already widely used overseas in commercial hot water, food processing, and industrial applications. It’s already doing the job in other sectors. We’re just applying it to dairy.
