Atlas Copco’s Oil-free Air division launched an energy-efficient centrifugal compressor range, designed to save up to 7% on specific energy at full load and up to another 9% at part load. Composed as a plug-and-run package, the ZH 355+ - 900+ oil-free centrifugal compressor range employs advanced aerodynamics to reduce energy consumption in the core. All of the components are created based on Computational Flow Dynamic (CFD) analysis to drastically reduce pressure drops in the package.
