STULZ CyberCool Free Cooling Booster cooling system

The STULZ CyberCool Free Cooling Booster offers a flexible, high-performance cooling solution designed for data centres. It enables the savings potential of free cooling to be fully exploited in both new and existing systems. This not only maximises operational reliability and enhances equipment lifespan, it also reduces CO₂ emissions.

Water-cooled chillers that previously did not meet the technical requirements for using free cooling can now be retrofitted with the cooling system, which is fully integrated into the hydraulic system. The plug-and-play facility has a high level of prefabrication, meaning it can be used with most conventional chilled water systems. It offers factory-tested hydraulics, coordinated cooling components and intelligent control, with the option of high-quality part-load capable components with redundancy, and a mode of operation with or without glycol.

Available in five sizes with cooling capacities between 270 and 1800 kW, the cooling system is designed to provide optimum control and communication. The integrated control cabinet solution uses patented free cooling control software, based on SEC.blue 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 product 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 provides effective free cooling capability and condensation temperature control — even with higher outside temperatures.

When combined with the STULZ Explorer WSW and CyberCool WaterTec chillers, the cooling system forms a coordinated and energy-efficient air-conditioning system.
