  1. 1. Rittal – CRAC systemsFresh powerfor data centres and server rooms
  2. 2. IT-specific climate controlModern IT climate control technology ensuresoptimum thermal conditions in rooms exposedto high loads, such as data centres and serverrooms. The main aim here is to ensure constanttemperatures and precise humidity levels.Continuous-operation designs and redundantsystems ensure that all key functions aremaintained.Rittal CRAC systems dissipate waste heat from theIT equipment on demand, ensuring that the overallsystem operates in the most energy-saving waypossible. Conventional system: Rittal CRAC system: The fan is positioned inside the raised floor. This facilitates a larger heat exchanger area, as well as a larger filter area. This configuration is designed to minimise internal installa- tion and deflection losses. In turn, the reduced power con- sumption (Δ Pw) produces considerable energy savings. Advantages of the new technology ● No losses from flow ● Enlarged heat exchanger deflection, and no loss and filter area of installation height ● Low energy consumption ● Optimum cold air and space requirements distribution ● Superior cooling output2 Rittal CRAC systems
  3. 3. Rittal CRAC systems are used for base load cooling of computer rooms.The systems, based on the tried-and-tested Rittal TS 8 enclosure system, are equipped with a heat exchanger inthe upper section. Underneath the raised floor is a high-efficiency EC radial fan which blasts cooled air into theraised floor without any further deflections.Applications:Combination with cold aisle containment Combination without cold aisle containmentHere, CRAC systems are used in conjunction with Rittal cold aisle Here, CRAC systems are used in conjunction with standard air dis-containment. The system is designed with 1+1 redundancy. tributors, making use of the hollow space beneath the raised floor. The system is designed with 1+1 redundancy.The hot air expelled at the rear of the cold aisle containment isdrawn in freely from the room and processed. After filtering and The heated air is drawn in freely from the room and processed. Aftercooling, and with optional additional dampening or drying, the filtering and cooling, and with optional additional dampening or dry-air is returned to the raised floor, which serves as a hollow space ing, here too the air is returned to the raised floor, which serves as athrough which the air is routed. hollow space through which the air is routed.Benefits:● Supports high return air temperatures of more than 30˚C● Very high level of efficiency CRAC system Cold water variant: Refrigerant variant: In this design, the customers This design comprises the key in-house cold water system is components of a cooling circuit used as the cooling medium, for (compressor, evaporator coil example, with a water/antifreeze and expansion valve).
