Modern IT climate control technology ensures optimum thermal conditions in rooms exposed to high loads, such as data centres and server rooms. The main aim here is to ensure constant temperatures and precise humidity levels. Continuous-operation designs and redundant systems ensure that all key functions are maintained. Rittal CRAC systems dissipate waste heat on demand, ensuring that the overall system operates in the most energy-saving way possible.
CRAC system
A Cold water variant
The extracted ambient air is cooled in an air/water heat exchanger
The cooling medium (cold water) is supplied by an external IT chiller system
Must be connected to a water-carrying pipeline system
B Refrigerant variant
The extracted ambient air is cooled in a direct evaporator (air/coolant heat exchanger)
Integration of the coolant compressor inside the unit, for internal generation of the cooling output
Heat is dissipated from the cooling process via a condenser sited outdoors
Must be connected to a pipeline system filled with coolant
System benefits
Enlarged heat exchanger surface area
No losses from flow diversion inside the enclosure
Direct mounting and air expulsion in the raised floor
Speed control
Energy-efficient EC fan system
Height adjustment
High level of stability, thanks to firmly linked frame section
