Most Energy-Efficient Oil Free Air Compressor
Atlas Copco says its ZH 350+, a manufacturer new high-speed, three-stage turbo, oil-free oxygen compressor, could be the most energy-efficient oil-free compressor
how the organization has actually produced. The ZH 350+ is developed for use in pharmaceutical, electronics, aviation, automotive as properly as other industrial sectors that count on high-quality, 100 % oil-free air. It could be the initial medium-pressure, commercial centrifugal compressor to become commercialized with high-speed motors (without a gearbox), and provides chances for further power cost savings when in comparison to traditional turbo compressors
. The initial ZH 350+ products can be transporting to potential customers in June.
The new compressor’s reduce energy usage is attributable to 5 layout elements. First, the three-stage layout is extensively recognized as one of the most effective for achieving compression in between 100 and 160 psi using a turbo compressor. The three-stage layout outcomes in typical lifecycle charges as significantly as 18 % reduce when in comparison to some two-stage turbo design. (Proceedings of ASME Turbo Expo 2008: energy for Land, Sea and Air, June 9-13, 2008, Berlin, Germany. cardstock Ref No.: GT 2008-51353.)
Second, the ZH 350+ eliminates the gearbox, hence eliminating the transmission losses linked using a gearbox. Transmission losses alone can decrease power effectiveness by as significantly as 9 % in compressors with the 350 kW range.
Third, the ZH 350+ has titanium impellers, that are not just much more reliable, but in addition permit quicker load-unload cycles. This enables for quick rate modifications which outcome in decreased energy losses throughout occasions of low-air demand.
Fourth, optimally sized coolers considerably decrease stress drop, enhancing the stability of subsequent compression changes. The layout also attributes an improved heat-transfer area.
Finally, the technique blows away prior to the aftercooler, minimizing compressed oxygen losses when oxygen need decreases.
The blended decrease in oxygen losses, stress drops, and transmission losses outcome in the compressor that is much more energy-efficient compared to company’s top-performing compressors below comparable running conditions. even more power cost savings are feasible using the new rotary drum heat-of-compression dryers (MD/ND) for centrifugal compressors, which have been presented in the Hannover Messe, April 4-8.
The ZH 350+ was licensed ISO 8573-1 (2010) course 0 with regard to essential oil articles through the impartial Technischer überwachungs-Verein (German specialized Monitoring Association), or ‘TüV’ on March 30, 2011.
“Atlas Copco is proud to arranged the traditional for compressed oxygen power efficiency,” says Chris Lybaert, president of Atlas Copco’s Oil-Free oxygen Division. “The reliability and power overall performance from the ZH 350+ is evidence of Atlas Copco’s on-going dedication to our customers’ productivity.”
