WOP 0009÷0155

CHILLED WATER UNITS WITH EC INVERTER PLUG-FANS

Chilled water units. The liquid Chiller can be watercooled or aircooled, with Free-Cooling technology too. The liquid flow through the unit water coil is managed by a 3-way internal valve.
The WOP range is equipped with EC Inverter Plug-Fans; High Head fans are available as accessories.
The EC Inverter Plug-Fans allow fuel consumption at partial loads to be reduced by up to 61% compared to radial fans, modulating the power consumption according to the required thermal load.
The WOP range is available in two air delivery configurations: WOPT with upflow and WOPB 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 WOP units can operate with water at a high temperature (13/18°C) thanks to the specific HT accessory: the batteries are optimised for this set point to achieve greater energy efficiency.
