Stulz booster adds free-cooling functions

GERMANY: Stulz has announced the worldwide availability of its CyberCool Free Cooling Booster, a simple add-on module that provides water-cooled chillers with free cooling functionality. 

The CyberCool Free Cooling Booster is said to offer a flexible high performance cooling solution in both new and existing systems, without any major planning or installation effort. 

According to Stulz, water-cooled chillers that previously did not meet the technical requirements for using free cooling can now be retrofitted with the CyberCool Free Cooling Booster, which is fully integrated into the hydraulic system. 

The plug-and-play facility with a high level of prefabrication, means it can be used with most conventional chilled water systems without additional high costs. 

It offers factory tested hydraulics, coordinated cooling components and intelligent control. Part-load-capable components with redundancy, and a mode of operation with or without glycol, are options.

The range comprises five sizes with cooling capacities from 270kW to 1800kW. 

An integrated control cabinet uses Stulz’s SEC blue controllers, 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 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.
