Atlas Copco proves superior energy efficiency of screw technology for air blowers
TÜV certificate emphasizes outstanding performance data of ZS screw blower
Antwerp, Belgium, June 28, 2010: The introduction of air blowers using internal compression instead of external compression sets a new standard for energy efficiency in the low-pressure market. This is the main conclusion of a technical whitepaper published by Atlas Copco’s Oil-free Air Division, explaining the differences between screw technology and the traditional ‘Roots’ type lobe technology. The on average 30 percent more energy efficient screw technology is used in the manufacturer’s recently introduced full range of ZS screw blowers that improve energy efficiency for low-pressure applications and industries such as wastewater treatment and pneumatic conveying
The range of ZS screw blowers uses the concept of internal compression, while the traditional “Roots” type lobe blowers rely on external compression to obtain an external system pressure. The detailed technical whitepaper demonstrates that, with a thermodynamic approach, internal compression is more efficient than external compression from 0.4 bar(e) / 5.8 psi(g) upwards. Tests, witnessed and certified by the independent Technische Überwachungs-Verein (German Technical Monitoring Association, or TÜV) have proven that the ZS is 23,8 percent more energy-efficient than a tri-lobe blower at 0,5 bar(e)/7 psig, and 39,7 percent at 0.9 bar(e)/13 psig. The technical whitepaper, TÜV certificate and additional information, images and movies can be found on http://www.efficiencyblowers.com/.
