Dual Coil units with two independent cooling circuits, both with chilled water. The circuits are connected with two water cooled or air cooled liquid Chillers, with Free-Cooling technology too. The two circuits are separated with nonsimultaneous start-up, for back-up operation.
The DOP range is equipped with EC Inverter Plug-Fans; High Head fans are available as accessories.
The EC Inverter Plug-Fans allow fuel consumption at partial loads to be reduced by up to 61% compared to centrifugal fans, modulating the power consumption according to the required 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.
