Helping Data Centres Beat the Heat

STULZ has announced the worldwide availability of its CyberCool Free Cooling Booster, an innovative free cooling module that enables data centres and industrial applications to benefit from environmentally friendly cooling.


The latest addition to the company's CyberCool range means water-cooled chillers can now be supplemented with modern free cooling functionality without any major planning or installation effort.

Free cooling is considered one of the most highly effective ways to reduce the energy consumed by chillers, or the time that they run for, by using the outside temperature of air or water. The approach has been demonstrated to enhance operational reliability whils extending equipment lifespan and reducing CO2 emissions.

According to STULZ, Water-cooled chillers that previously did not meet the technical requirements for using free cooling can be retrofitted with the CyberCool Free Cooling Booster as it integrates into hydraulic systems with "plug and play" functionality. To provide the most flexible and controllable solution possible, the solution utilises factory-tested hydraulics, coordinated cooling components and intelligent control, and can operate with or without glycol.

Available in five sizes with cooling capacities between 270kW and 1800kW, the CyberCool Free Cooling Booster ensures optimum control and flawless communication. The integrated control cabinet solution uses patented free cooling control software, based on controllers from STULZ, which feature an integrated Ethernet interface and a micro-SD port for firmware upgrades and data management. This intelligent controller monitors both the outside and the operating temperatures, and regulates the cooling capacity according to current demand.

The CyberCool Free Cooling Booster supports three operating modes – free cooling, mixed mode and mechanical cooling. Depending on the outside temperature, the system automatically selects the most appropriate mode to ensure efficient operation. As a result, it ensures the most effective free cooling capability and condensation temperature control – even with higher outside temperatures.
