Daikin Oil Free Centrifugal Chiller Range Offers Increased Energy Efficiency and Reliability


Daikin Europe N.V. has introduced a new EWWD-FZ range of centrifugal chillers that incorporate oil free compressors with magnetic bearings. This compressor technology not only eliminates the need for oil as a lubricant and associated maintenance and reliability issues, it also contributes to making this range one of the most energy efficient on the market.

Broad range of industrial applications

The new chillers are designed for a broad spectrum of industrial applications and come in 6 sizes (single circuit, 1 or 2 compressors) with cooling capacities from 320 to 1,050 kW. All units include onboard monitoring and diagnostics, can be easily integrated with external control systems such as building management systems and sequencing panels and are available with a wide variety of options.

Oil free operation improves reliability and efficiency

Oil free magnetic bearings contribute to simplified design and increased reliability. Friction is eliminated, as is the need for additional equipment such as oil pumps, resulting in reduced maintenance and greater reliability. Vibration and sound levels are also reduced significantly, allowing the units to be installed 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 plus a flooded type evaporator, provide outstanding partial load efficiency and significant energy savings (EER up to 6.0 and ESEER up to 9.60). Integrated soft start functionality also greatly reduces start-up current requirements.

Daikin Europe products are distributed in the UK by Daikin Airconditioning UK Ltd and Space Airconditioning plc.
