CO₂ GLYCOL CHILLERS

Fast, efficient milk cooling - with free hot water at the same time

Eco2Energy glycol chillers cool milk quickly and consistently to 3–4°C, meeting dairy company requirements before pick‑up. At the same time, the system generates free 85°C hot water – two jobs done with the same energy.

WHAT FARMERS NOTICE

Fast, stable cooling.
Free hot water. Less Power

Milk hits 3 - 4°C quickly

Fast cooling and stays there - no creeping temperatures or borderline readings before pickup

Free 85°C hot water

450–750 L/hr of free hot water generated as a by-product of the cooling process

Up to 65 - 85% power savings

CO₂ compressor control dramatically reduces electricity consumption vs traditional systems

Meets dairy company requirements

Consistent performance ensures compliance with NZ dairy company temperature specifications

Reliable through calving

Designed for the pressure of peak milking periods — performs when you need it most

WHY CO₂ FOR MILK COOLING?

Futureproof refrigeration for growing herds.

Most dairy refrigeration systems were installed when high-GWP refrigerants were standard. These gases are now being phased down, making them harder and more expensive to service.

CO₂ avoids that uncertainty and performs better.

How our CO₂ glycol chillers work

CO₂ pulls heat from your milk and turns it into free hot water

1.

Pulls heat from the milk

Chilled glycol circulates through the plate cooler, absorbing heat from the warm milk as it enters the system.

2.

Boosts the heat

The CO₂ compressor concentrates the captured heat using minimal electrical power – this is what makes the system so efficient.

 

3.

Uses the heat - two ways

The system upgrades that heat into 85°C hot water at 450–750 L/hr, while simultaneously cooling milk to 3 – 4°C. Two jobs, one energy cycle.

4.

Recycles energy

CO₂ resets and the cycle repeats – delivering efficient, continuous cooling and consistent hot water throughout every milking session.
