High partialhybrid freecooling mode

Here are a number illustrating the energy savings for Stockholm, in terms of energy consumption, achieved using TETRIS W FC/NG HE, in compari-son to a water cooled standard unit, assuming that the cooling need is constant throughout the year.

Tetris W FC / NG combines all the advantages of high ef-ficiency water-cooled chiller (Tetris W range) with the hybrid freecooling integrated system

•Hybrid free CoolingUnit performs full nominal capa-city with compressors operating at part load with reduced power consumption.

• 100% Free Cooling (Winter)Unit performs full nominal capa-city only using Dry Cooler fans and with compressors OFF.

HYBRID FREE COOLING

* Evaporator inlet-outlet water temperature 15-10°C; condenser inlet-outlet water temperature 30-35°C (e.g. 30%)

NOT ONLY FREECOOLINGHigh efficiency in summer mode

Thanks to high performan-ce of the chiller side, Tetris W FC/NG ensures high ef-ficiency of the plant during all the year. The product adapts and optimises itself to the seasons, providing a high return all year round.

EASYINSTALLATIONTetris W FC / NG provides a lot pof op-tions and pumping configurations to suit every requirements. The footprint is designed for indoor in-stallation (max width below 900 mm). The structure provides also the division in two section for sizes long over 5 me-ters to allow an easy movement in inte-rior spaces. This means:• Less design time• Quicker and less cost for installa-

tion team• Few connections

INVERTER DRIVEN PUMP ON SOURCE SIDEInverter driven pump on source side as standard:• Reduced energy consumption• Greater control of condensing tempe-

rature in partial freecooling.

FULL INTEGRATEDCONTROL SYSTEMAdvanced built-in control to manage the 3-way modulating valve, inverter driven pump on the source side and the fan speed adjuster of the dry cooler.No need additional cost for controls in-tegration.

GLYCOL FREE Thanks to the built-in decoupling heat exchanger Tetris W FC/NG is Glycol free on user side. This means:• more efficiency on user side with only

water• the plant doesn’t need to be monitored
