New generation Chilled Water Close Control units characterized by the combination of two parts: the upper cooling module which includes an high performing coil, filters, electrical box, modulating valve and the newest EC Inverter Plug-Fans are housed in a dedicated module optimized for minimum air pressure drops and reduced electrical absorbed power. The fan module, normally configured "fully open" for installation under the raised floor, can be provided with panels for installation above the raised floor.
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.
These units are designed to operate with high water temperature (14/20 °C), despite being possible to operate with conventional water temperature (7/12 °C).
