Water Cooled Inverter Screw

FR2-W-G04 0402 – 1242
The new water source range of chillers specifically developed for IT cooling applications with variable-speed screw compressors and HFO R1234ze refrigerant, covering a capacity range from 613 to 1894 kW (28/20 °C evaporator side, 30/36 °C condenser side). The complete range is Eurovent certified, and, thanks to the leading inverter technology, all the sizes far exceed the SEPR HT minimum seasonal efficiency limit of 2021 imposed by EcoDesign Directive. i-FR2-W-G04-Z units are also characterized by a wide operating range, working at full loads up to 20°C of evaporator leaving water temperature and up to +52°C of condenser leaving water temperature as standard. The operating limits can be further improved thanks to the HWT kit (Hot Water Temperature kit): with this option, the unit can reach a condenser leaving water temperature up to 72°C at full loads, making it suitable for high temperature district heating applications, or for heat recovery applications. The structure of the unit has been designed expressly to host the acoustical enclosures that are able to significantly reduce the sound power level, and are available in 2 versions:

• Compressors’ acoustical enclosure: -6 dB(A)
• Integral acoustical enclosure: -16 dB(A) (best-in-class)
