Daikin Europe N.V. announces the launch of EWWD~FZ, a new centrifugal chiller range that uses oil-free compressors featuring magnetic bearings. This compressor technology not only eliminates the need for oil as lubricant and the associated maintenance and reliability issues, but also contributes to making this range one of the most energy efficient on the market.
Oil-free operation improves reliability and efficiencyOil-free magnetic bearings allow for a simplified design and increased reliability. Friction is eliminated, as is the need for additional devices such as oil pumps, resulting in reduced maintenance and greater reliability. Vibration and sound levels are also reduced significantly, allowing the units to be used in sound sensitive environments.
The magnetic bearing system and other technologies present in the oil-free compressor make it one of the most efficient compressors on the market today. Moreover, the compressor’s integrated variable frequency drive, together with a flooded type evaporator, provides outstanding partial load efficiency, adding to the energy savings (EER up to 6.0 and ESEER up to 9.60). Integrated soft start functionality also greatly reduces start-up current requirements.
Broad range of industrial applicationsThe EWWD~FZ range is available in 6 sizes (single circuit, 1 or 2 compressors) with cooling capacities from 320 to 1,050 kW. The units include on-board monitoring and diagnostics, and can be easily integrated with external control systems such as building management systems and sequencing panels. The units are available with a variety of options making them suitable for a broad range of requirements and applications.
