Some data centres have a central chilled water supply. Direct liquid cooling of high-density server racks via the central water supply seems an obvious solution, but does not answer to the requirements of the racks and also carries a major threat of leakage.

STULZ CyberCool Pump&Transfer ensures that the system is separated into two circuits, keeping the volume of water and pressure in the rack as low as possible. In the primary circuit between the central chilled water supply and the transfer station, CyberCool Pump&Transfer works with a water/glycol mixture at low temperature. In the secondary circuit, the transfer station feeds glycol-free water to the server racks, while adapting the temperature to the level required by the racks.
