The SCREWLine³ FREE_COOLING enables high-level savings on the management costs of the system in applications which also require cooled water during the cold season such as industrial processes, data centres, telecommunications, technological applications and shopping centres.
SIGNIFICANT ENERGY SAVINGS - When the fresh air temperature is lower than the return water temperature of the system, the FREE-COOLING system recovers coolness from the external setting and reduces compressor operations until they are completely stilled. In this way the requested cooling capacity is supplied at no cost. 
EVEN IN GLYCOL FREE VERSION - Does not require the addition of an antifreeze substance in the hydraulic circuit used. Therefore, it is particularly suitable for large-sized systems and wherever laws and regulations limit the use of antifreeze substances inside buildings.
CONTINUOUS CAPACITY CONTROL - The continuous capacity control allows for a quick adjustment of the system’s load and therefore an accurate control of the chilled water temperature with an exceptionally wide operating range.
EFFICIENT AND RELIABLE TECHNOLOGY - SCREWLine³ employs the new generation dual screw compressors, electronic expansion valves, shell and tube evaporator and fans with innovative AxiTop diffusers with kinetic energy recovery
