Watercooled direct expansion units with Scroll compressors and EC Inverter Plug-Fans
TO 134 KW
TO 38 TON)
Watercooled direct expansion units. The room air is treated in the evaporator coil where the refrigerant flows; the condensation heat is discharged in an internal plate exchanger, connected with a water circuit with well water, local water supply or closed systems such as evaporative towers and/or dry coolers.
The HOP 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 HOP range is available in two air discharge versions: HOPT with top air discharge and HOPB 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.
