Watercooled direct expansion units with Scroll compressors and radial 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 HOC range features radial fans; high ESP fans are also available as accessory.
The HOC range is available in two air discharge versions: HOCT with top air discharge and HOCB 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.
