EASY INSTALLATION FULL INTEGRATED CONTROL SYSTEM Advanced 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 integration. INVERTER DRIVEN PUMP ON SOURCE SIDE Inverter driven pump on source side as standard: Reduced energy consumption Greater control of condensing temperature in partial freecooling. Tetris W FC / NG provides a lot pof options and pumping configurations to suit every requirements. The footprint is designed for indoor installation (max width below 900 mm). The structure provides also the division in two section for sizes long over 5 meters to allow an easy movement in interior spaces. This means: Less design time Quicker and less cost for installation team Few connections 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 (ethylene glycol is poisonous for humans) Glycol OUT source IN user No Glycol Unit Size 3.2 4.2 5.2 6.2 7.2 8.2 9.2 10.2 12.2 13.2 15.2 17.2 19.2 20.2 24.2 27.2 Cooling Nominal cooling capacity (1),(6) kw 39 45 52 57 66 74 85 103 117 135 150 166 188 206 229 258 EER (1) 4,69 4,66 4,74 4,77 4,72 4,73 4,78 4,79 4,78 4,79 4,82 4,79 4,76 4,67 4,66 4,69 EER (EN 14511-3:2011) (1),(6) 4,10 4,01 4,14 4,18 4,20 4,09 4,17 4,23 4,31 4,26 4,29 4,23 4,24 4,17 4,26 4,23 Basic unit size and weights Lenght mm 1633 1633 1633 1633 1633 1633 1633 1633 3300 3300 3300 3300 3300 3300 3300 3300 Width mm 800 800 800 800 800 800 800 800 800 800 800 800 800 800 800 800 Height mm 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 Unit Size 30.3 34.3 40.3 18.4 20.4 24.4 26.4 30.4 34.4 38.4 40.4 48.4 54.4 56.6 60.6 Cooling Nominal cooling capacity (1),(6) kw 328 370 414 169 204 233 263 297 331 377 423 468 527 563 634 EER (1) 4,81 4,84 4,86 4,74 4,72 4,77 4,77 4,78 4,75 4,72 4,73 4,62 4,70 4,73 4,73 EER (EN 14511-3:2011) (1),(6) 4,37 4,35 4,36 4,22 4,33 4,34 4,23 4,39 4,23 4,29 4,23 4,28 4,29 4,28 4,28 Basic unit size and weights Lenght mm 4505 4505 4505 3685 3685 4502 4502 4502 4502 2820 + 2930 3320 + 2930 Width mm 880 880 880 880 880 880 880 880 880 880 880 880 880 880 880 Height mm 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 1880 (1) Evaporator inlet-outlet water temperature 15-10 C; Condenser inlet-outlet water temperature 30-35 C (e.g.30%) (6) Values conform to EN 14511-3:2011 This board reports the feature data of the base and standard versions; for details, refer to the specific documentation.
