Chilled water Dual Coil units with EC Inverter Plug-Fans
TO 93 KW
TO 26 TON)
Dual Coil units with two independent cooling circuits, both with chilled water.
The circuits are connected with two watercooled or aircooled liquid Chillers, with Free-Cooling technology, too. The two circuits are separated with nonsimultaneous start-up, for back-up operation.
The DOP range features EC Inverter Plug-Fans; high ESP fans are also available as accessory.
The EC Inverter Plug-Fans allow consumption reduction at partial loads up to 61% comparing to radial fans, with the modulation of absorbed power depending on the real thermal load.
The DOP range is available in two air discharge versions: DOPT with top air discharge and DOPB with bottom air discharge.
Unit supervision is developed by means of Modbus RTU protocol over RS485 serial interface as standard configuration. Other communication protocols and interfaces are available as option.
