Always the right choice: CyberCool Indoor with three cooling systems
Energy efficiency, investment volume, operating costs, room size, noise protection, redundancy and local climate - every project has its own requirements in terms of appropriate chilled water generation. Our customers can choose between different configurations and so achieve an ideal balance between capital investment, running costs and energy efficiency. STULZ is the world's only manufacturer to offer such a huge range of configuration options.
Air-cooled: The compact standard solution (A/AS)
A chilled water circuit transfers the heat load to the evaporator where the heat is drawn from the water and passed to the refrigerant. The refrigerant gives off the heat to the outside air via an air-cooled condenser.
Water-cooled: Quiet and easy to integrate (G/GS)
Like A/AS on the direct evaporator principle - with one difference: the heat is transferred to a water/glycol mixture via an integrated plate condenser; this mixture gives off its heat to the outside air in a closed circuit via an external dry cooler.
Water-cooled with integrated free cooling function: Maximum efficiency (GE/GES)
Like G/GS, but with indirect free cooling which replaces energy-intensive compressor operation in part or in full when outside temperatures are low. In FC mode, the heat is transferred straight to the chilled water circuit by an integrated free cooling heat exchanger and given off into the outside air via an external dry cooler.
Maximum efficiency with direct cooling
The most efficient mode is selected automatically depending on outside temperature – reliably throughout the whole year and whatever the local temperature profile.
