STULZ (Precision Air Conditioning)

Water
Compact system separation with Pump&Transfer
Some data centres have a central chilled water supply. Direct
water cooling of high-density server racks via the central water
supply seems an obvious solution, but does not meet the
requirements of the racks and also carries a major risk 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.
CyberCool Pump&Transfer stations are available as single or
dual circuit systems. The dual circuit system ensures 100 %
redundancy whilst taking up the same space. The integrated
microprocessor monitors all functions, processes signals from
water warning systems when required, and enables the
CyberCool Pump&Transfer to be incorporated in the central
building services management system.
