WATERCOOLED DIRECT EXPANSION FREE-COOLING UNITS WITH SCROLL COMPRESSORS AND RADIAL FANS
Units with two separate cooling systems, a primary direct expansion circuit (DX) and a secondary chilled water circuit (CW). The units feature a microprocessor that manages 3 operating modes: DX only, MIXED and CW. Based on the external temperature, it allows to maximize the energy savings by intelligently managing the three operating modes. This type
of unit is especially suited for systems requiring particular RELIABILITY and ENERGY SAVING for the entire air-conditioning system.
The FOC range is equipped with centrifugal fans; High Head fans are available as accessories.
The FOC range is available in two air delivery configurations: FOCT with upflow and FOCB 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.
- FOC…/C - Cooling only
- FOC…/U - Cooling and humidification
- FOC…/E - Cooling and heating
- FOC…/D - Cooling, heating, humidification and dehumidification
