Free Cooling for water-cooled chillers

Systems with water-cooled chillers do not usually offer Free Cooling, even if the low outdoor temperatures at the installation site would allow it. However, since Free Cooling – as well as a precise Mixed mode concept – offer the greatest potential savings, STULZ has developed a standard unit that benefits from low outdoor temperatures and thus ensures efficient operation all year round.

Quick and easy installation

CyberCool Free Cooling Booster is a high-performance solution designed for plug-and-play installations, making it suitable for any location.

The standard unit is a pre-installed system that contains all important hydraulic components, so that installers don't need to take any construction measures to integrate Free Cooling. Due to the unit design, the Free Cooling modules can be installed quickly and easily, which reduces commissioning times and installation costs significantly.

With or without glycol

CyberCool Free Cooling Booster features a built-in intermediate heat exchanger, which separates the user from the dry cooler circuit, ensuring operation without glycol on the user side.

Control and Monitoring

Thanks to its own switch cabinet including SEC.blue controller, optimum control and perfect communication with chillers and dry coolers are ensured. SEC.blue monitors both the outdoor and the operating temperature and regulates the cooling capacity of the dry cooler. Optimum control of the condensing temperature and maximum amount of Free Cooling hours are ensured even at high outdoor temperatures. This results in minimal operating costs and a low CO2 footprint.
