Chilled Water System

This system is based on chilling a large quantity of water which is then pumped through a heat exchanger alongside your existing primary cooling farm water supply to cool down the milk so that it’s at a temperature of around 8 - 10°C before it reaches the vat.

The vat refrigeration system therefore only needs to cool the milk down a further few degrees to reach the 6°C regulation, meaning there is a lot less pressure on the vats refrigeration system to chill the milk than is currently the case.

Advantages of a Daikin Chilled Water System

  • It has an inverter-controlled compressor so the compressor can slow down with reduced load. This provides money savings due to reduced electricity consumption by the refrigeration unit.
  • Increased performance because of the inverter of the compressor, which can over run above the rated capacity of the unit at peak demand.
  • Has a larger volume of thermal mass to draw from due to 25,000 litre water tank.

"The milk is going into the vat cold which is the best thing. It also draws very little power; you hear the refrigeration stop as soon as the milk goes into the vat – that’s impressive. Chilltech were great to deal with, I’m really pleased with my system." - Greig Alexander – Farmer

Case Study

Chilltech installed a Daikin Chilled Water system on a Northland farm in March 2016 and the team instantly saw improvements in not only milk temperature but also the speed and power used to achieve the results. Each of our case study systems have been fitted with data logging equipment in order to track performance and monitor water and milk temperatures.

Milk cooling data logging is a recommended part of the new MPI requirements. Information should be held for 30 days. Chilltech can install a data logging mechanism on your system to take the hassle out of recording your own temperatures everyday. All data is instantly downloadable to USB for storage.

Farm Stats:

  • Daikin EWAQ025 25Kw Water Chiller
  • 9,000 Litres per day milk production at peak
  • 345 Cows
  • 2 x a day milking
  • 21,500 litre vat with side pads. 13hp on base pad / 7 ½ hp on side pad.
