Heat Exchanger
Cooling for server rooms and data
centres using a heat exchanger station

A heat exchanger integrates additional cooling sources into a data centre’s cold water network, leading to energy savings. Direct cooling allows a high proportion of free cooling. Primary and secondary cold water circuits are separated from each other.


An optional water storage connection or a chiller can absorb temperature peaks. And a water pump can also be connected.

FAQ Heat Exchanger
What are heat exchangers needed for?

The heat exchanger separates the cold water network of the building from the cold water circuit for the IT components, so that the IT cold water network can be operated separately from that of the building.

Why can higher operational reliability be achieved with a heat exchanger?

Together with a cooling unit (a Sidecooler or Backcooler), the heat exchanger forms a secondary cold water circuit. If cooling fails in the primary circuit (belonging to the building), pumps in the heat exchanger continue to pump water in the secondary circuit. Cooling can then be guaranteed for the IT components for some time, depending on the water volume in the secondary circuit.

What cooling sources can be integrated into the heat exchanger’s cooling circuit?

Besides the standard source, optional cooling sources such as well or spring water, water from cisterns, etc. can be integrated into the secondary cold water network via a second heat exchanger.
