ProCool™ Glycol

On-demand snap chilling.

These systems use a mixture of food grade glycol and water to create the chilled fluid on demand, at milking time. With a correctly sized refrigeration unit, the system can chill milk to 4°C before entering the vat.

The compact glycol solution is ideal for farms with high water temperatures and a good supply of power during the milking period.
