Centrifugal Compressor Employs Advanced Aerodynamics to Reduce Energy Consumption
Atlas Copco has launched a new centrifugal compressor range that’s been designed to save up to 7 percent on specific energy at full load and up to another 9 percent at part load.
Delivered as a plug-and-run package, the new Atlas Copco ZH 355+ - 900+ oil-free centrifugal compressor range employs advanced aerodynamics to reduce energy consumption in the core. Coupled with this, all the components of the package are designed based on computational flow dynamic (CFD) analysis to reduce pressure drops in the package.
The result is a reduction of specific energy up to 7 percent at full load compared to the previous model. Inlet guide vanes, which are part of Atlas Copco’s standard scope of supply, further reduce energy cost by 9 percent at part loads as compared to a throttle valve control.
To ensure continuous production for the users, ZH centrifugal compressors from Atlas Copco employ high-end features to ensure maximum uptime. This includes milled impellers and servo-controlled inlet guide vanes.
The units also provide Class 0 certified quality of air. A fail-safe sealing system prevents the possibility of contamination of the air with oil, without the need of any external buffer air. Oil fumes from the gear box are captured by a motorized demister, thus eliminating the risk of ingestion of oil fumes along with the intake air. This safeguards the end product of the customers against oil contamination.
