90 TURBOCOR VERSIONS: UNICO TURBO (R134a) Cooling capacity 260,0 1420,0 kw A CLASS ENERGY EFFICIENCY VERSION The TURBO series is characterized by its high energy efficiency, even when working at partial loads, thanks to the special compressor installed in these units. The TURBO liquid chillers are provided with an innovative two-stage centrifugal compressor with magnetic levitation bearings providing deliver Liquid chiller equipped with magnetic levitation two-stage and axial fans. (R134a) new Cooling capacity 280,0 1840,0 kw Water cooled liquid chillers equipped with magnetic levitation two-stage centrifugal compressors and flooded evaporator. revolutionary features and benefits compared to the traditional machines available in the market. First of all, the magnetic levitation bearings eliminate the presence of oil inside the compressor and consequently inside the refrigerant circuit, while the compressor electric motor is controlled by an inverter, obtaining a continuous cooling capacity variation from 20 to 100%. The cooling capacity is controlled also by the movable inlet guide vane system on the compressor s suction port that diverts the angle of the gas entering the impeller as needed. This allows to follow with considerable accuracy the trend of system thermal load. Trademarks used are properties of their respective owners.

This solution allow to achieves the same leaving water temperature, but with an higher refrigerant evaporating temperature: the reduction of the differential between the condensing pressure and the evaporating one is immediately translated into a significantly higher overall efficiency of the machine.
