Daikin’s DZ Series oil-free water-cooled inverter chillers are fitted with centrifugal compressors which utilise frictionless magnetic bearings for oil-free operation. There’s therefore no need for an oil management system which is said to result in increased reliability and reduced maintenance.

The firm says the absence of oil in the refrigerant circuit delivers higher heat exchanger performance compared to traditional oiled centrifugal chillers. 

It claims the models in its new line-up combine high efficiency compressors and heat exchangers to achieve an “impressive” performance. The designs also incorporateintegrated variable-frequency drives and high-speed direct drive technology.

The models in the DZ Series are compact and have a footprint that is 32 per cent smaller compared to their predecessors. Daikin says they provide a low noise solution with dedicated compressor soundproof cabinets to ensure “outstanding flexibility” to match any application.
