This option can be built into all K4, K6, K9 and K12 Chillers and is used where you have a central or house water supply:
Isolates the application from the house water supply (preventing contamination from elsewhere or damage from additives in the supply)
Has a more accurate control of coolant temperature
Allows the application to be cooled to a temperature other than the house water supply temperature
Reduces air movement near the chiller (especially useful in Clean Room conditions)
Water cooled Chillers require at least 10 litres/min cooling water at less than 26°C, with a differential pressure across the chiller of 1 bar.
