FWM 260÷909
WATER-COOLED FAN WALL UNIT WITH PLUG-FAN EC INVERTER FANS
The new generation of water-cooled Fan Wall units includes a high-performance coil, high-efficiency filters, electrical panel, modulating valve, and Plug-Fan EC Inverter fans.
The units include the Modbus RTU communication protocol on an RS485 serial interface as standard. Other communication protocols and interfaces are available as options.
The units are designed to operate with high-temperature water and a wide delta T, in order to reduce energy consumption.
