Innovation focus | August 2008 | 4 Innovative.Ground-breaking. Securing our future. S-VSI TWISTER and G-BH2 VELOCIS Technical market leadership is a fundamental aspect of our corporate philosophy – and we are once again proving this claim with the newly developed S-VSI TWISTER screw vacuum pump. In addition to considerable efficiency and a final vacuum of less than 0.1 mbar (abs.), the perfected screw profile provides maximum volume flow at high vacuum level. Maximum volume flow at high vacuum level The non-contact operation screw rotors of the S-VSI TWISTER require no lubrication in the working area. This means that there are no costs for disposing of contaminated oil. The improved screw rotors have a variable lead progression and are gear-synchronized. Suction capacity in m 3 /h Advantages of the new S-VSI TWISTER screw vacuum pump: • Short evacuation times • 0.1 mbar final vacuum • Low compression heat • High maximum tolerable water vapor inlet pressure • Low noise level • High suction capacity • Easy on maintenance • Highly effective • Variable number of revolutions possible • Less waste heat Robust, durable construction A long useful life and standard maintenance as well as compatibility with steam and fluid are important features of this construction concept. Noise and vibration levels are remarkably low. Vacuum range in mbar (abs.)
Innovation Innovation We are opening up new dimensions for this technology with the G-BH2 VELOCIS side channel blower. On the basis of our customers‘ requirement matrix – shown to us in our daily work – and free of previous patterns of thought, we have come up with a completely new concept. G-BH2 VELOCIS side channel blower Suction Capacity G-BH2 G-BH2 0 Vacuum Pressure Elmo Rietschle side channel blowers show just how reliable they are every single day; they are virtually maintenance-free in operation and are also more quiet than nearly any other vacuum pump or blower. On the basis of the sound know-how of our development department and of market requirements which have emerged from numerous, intensive talks with customers, a new generation of side channel blowers has been created: VELOCIS. Our customers discover and benefit from new applications for this technique. A significantly extended scope of operation opens up completely new areas for side channel technology – areas hitherto unknown. Even if until now predominantly rotary lobe vacuum pumps, claw pumps and dry-running rotary vanes have been used, more and more customers are convincing themselves of the advantages offered by VELOCIS. VELOCIS stands for: • Reduced life cycle costs • Unbeatable reliability and sturdiness • Extremely quiet operation • 40,000 operating hours • Quality motors with a wide voltage range and energy efficiency class 1 (eff1) • Frequency-controlled operation up to 100 Hz possible • Worldwide use (UL CSA-, IEC/EN certified) • ATEX 94/9 EG G-Serie Seitenkanal VELOCIS Die Revolution des Seitenkanalverdichters Entdecken Sie die neue Dimension Sie denken, Seitenkanalverdichter können nur noch in Details verbessert werden?

What do R&D engineers do best? Research and develop. But what do they spend most of their time doing? Administration work. This is why – in 2004 – the Elmo Rietschle R&D team in Bad Neustadt decided on a new approach towards their new project for improved side channel technology. An engineer who did not belong to the department was engaged for activities relating to project management. He monitored compliance with targets, ensured that deadlines were always met, organized meetings and was responsible for the paperwork. In retrospect, the development engineers are certain that this almost doubled their efficiency. The team also made optimal use of the finite element method (FEM) and managed to reduce the numbers of test machines being built at that time to two machines by enlarging and reducing data to result in considerable cuts in time and cost. During the course of this project other synergies resulted when the German company commenced with having specific individual components produced in low-wage countries and joined the corporate division in Quincy in Fluent, a simulation software program for workflows already being used by the company in America. On looking back at this successful project, which fulfilled fundamental aims in terms of speed, cost, quality and market success, the Elmo Rietschle R&D team is convinced that future projects will all follow the same pattern. Five patents submitted during the development phase is further proof of the exceptional work performed by these engineers. A report from R&D Bad Neustadt
