Daikin oil-free chiller on R515B
2nd October 2024
USA: Daikin Applied has introduced the Magnitude WME-D, a water-cooled centrifugal chiller featuring a two-stage, oil-free compressor and lower GWP refrigerant R515B.
The optimised compressor-refrigerant combination is said to improve performance for up to 40% more energy savings than traditional fixed speed compressors.
The WME-D chiller offers impressive cooling and heating capabilities, providing 900kW to 1,600kW of cooling and 1,000kW to 1,550kW of heating.
Its ultra-wide operational envelope allows for a range of functionalities, including free-cooling, inverted duty operation, evaporator leaving water temperatures up to 21ºC, condenser entering water temperatures as low as 4°C, and operation down to 10% capacity without the need for hot gas bypass.
Additionally, while most chillers only allow control of the evaporator leaving water temperature for cooling, the WME-D provides the option to control the condenser leaving water temperature for heating, achieving temperatures up to 52ºC.
