Daikin Europe 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.
The new chillers are designed for a broad spectrum of industrial applications and come in six sizes (single circuit, one or two 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 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.
