Free-cooling liquid chillers with axial fans<br />
TECHNICAL DATA IDENTIFICATION<br />
RCProactive<br />
MAXIMO.SCREW.A.STD “G”<br />
Air cooled packaged liquid chillers equipped with energy saving free-cooling SCR system, screw compressors<br />
and axial fans. Casing type: “G”.<br />
All MAXIMO range is equipped with microprocessors systems provided with RC PROACTIVE logic conceived to grant<br />
continuity of work even in emergency situations.<br />
For instance: in case of a restart after a possible stop of the units due to a blackout, the proprietary RESTART system<br />
(PROACTIVE logic integrated system), activates a restart procedure granting the chiller in operation even with a return<br />
water high temperature. Usually this situation would cause an immediate stop of the chiller (complete stop with manual<br />
restart need) for high pressure. RESTART is vital in all those plants with high thermal load and low inertia, where even a<br />
few minutes of energy loss (usually time needed for diesel generator start-up) would increase the water temperature in<br />
excess of that possible for any other chiller to start without the RESTART system.<br />
