In data centre environments, chillers are prized above all for their robust technical characteristics: constant, fail-safe performance and long operating life.
Chillers from the Stulz CyberCool 2 series are available as air-cooled versions with and without Free Cooling, with an output range from 10 to 1400 kW.
Development and production of these systems take place at Stulz headquarters in Hamburg, and are anchored in a stringent ISO 9001 quality management system, complete with final test run.
Even during the development of this new series, the exact demands facing modern data centre air conditioning were tackled down to the last detail: all system components have been adapted to work in harmony in the cooling system, and are designed for maximum reliability.
In addition, large EC fans (diameter 910 mm) for power reserves and energy efficiency in partial load mode, optional diffuser and an encapsulated compressor chamber ensure particularly quiet operation and enable problem-free use in urban areas.
Efficiency – Minimal energy consumption
To permanently reduce chiller system energy consumption, all Stulz CyberCool 2 air-cooled chillers are available with a Free Cooling option. Ultra-modern microchannel coils in a corrosion-resistant, all-aluminium design endow CyberCool 2 chillers with a high cooling capacity.
To ensure constant optimum flow through the coil elements, the condenser modules are equipped with special air baffles, which prevent flow-induced turbulence. In addition, the maximised coil surface provides improved heat transfer and a lower switchover point to Free Cooling mode.
Diverse options for specific
IT applications
CyberCool 2 chillers are available with a single or dual refrigerant circuit. The refrigerant circuits are arranged symmetrically and equipped with identical compressors. This lowers the cost of stocking spare parts, and simplifies both electrical and mechanical maintenance. A quick-start routine available for every compressor type guarantees the shortest possible start-up sequence, e.g. after a power failure. The compressors are available as scroll models with constant or variable speed up to an output of 600 kW. Units with higher output levels up to 1400 kW are equipped with sturdy screw compressors, or as speed-controlled versions with flooded evaporation.
The flexible size concept and compact design make it possible to create a custom-tailored cooling solution of nearly any cooling capacity and redundancy level. CyberCool 2 chillers are available with a dual mains cable (A+B supply) and manual or automatic switchover.
Moreover, equipped with Stulz’s own control technology, CyberCool 2 systems can be seamlessly integrated in all common building management solutions and DCIM systems.
