TREF FREE-COOLING

DX CRAC unit with modulating with indirect water Free-Cooling

Range: 24÷131 kW

Perimeter-mounted solutions from our TREF Free-Cooling series are designed for medium to large server rooms, laboratories or
other technical applications requiring continuous 24/7 precision control of temperature and humidity parameters. These units house
– in addition to the DX evaporating coil, arranged in series relative to the air flow – a dry cooler-fed chilled water coil. With this system
the room is cooled with little or no use of the compressor when the air outside is cooler than the warm air inside the room. This optimises the system’s overall power consumption and improves, as a result, the Data Center’s PUE (Power Usage Effectiveness).
