Free Cooling with CyberCool Free Cooling Booster

Free Cooling is an intelligent solution for minimizing energy-intensive compressor mode and significantly cutting operating costs. Equipped with an additional Free Cooling module, Explorer WSW uses the outside temperature, which offers the greatest potential for savings, especially in cold and temperate climates.

Without complex and extensive planning, the Free Cooling module can be easily integrated and connected to the piping via a Victaulic connection. Thanks to its own control cabinet including SEC.blue controller, optimum control and trouble-free communication with the Explorer WSW are ensured.
