XOP/SZ 1012÷2148

AIR COOLED DIRECT EXPANSION UNITS WITH SCROLL COMPRESSORS AND EC INVERTER PLUG-FANS

Air cooled direct expansion units. The XOP range features EC Inverter Plug-Fans; high ESP fans are also available as accessory.
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 XOP range is available in two air delivery configurations: XOPT with upflow and XOPB with downflow.
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.
The units are suitable for operation at a high outdoor air temperature (up to 52 C) with the correct combination with the XT remote condensers.

Versions
