The latest edition of ComVac will soon be staged: from 24 to 28 April 2017 in Hannover, Germany, under the umbrella of HANNOVER MESSE. All up, some 260 exhibitors will be there in halls 26 and 27 to shocase the current state of the art in industrial compressed-air and vacuum-air technology. As well as the perennially important theme of energy efficiency, the displays will have a strong focus on contracting, Industry 4.0 and predictive maintenance. “ComVac profiles all areas of the compressed-air and vacuum-air technology industry. This gives our visitors a comprehensive overview of the technology landscape and positions the industry as a key enabler,” explained Wedell-Castellano, Global Director ComVac, HANNOVER MESSE. “Moreover, from an exhibitor standpoint, ComVac offers valuable synergies with the other shows at HANNOVER MESSE. That is because the industrial companies who exhibit at those shows are very often also potential buyers of compressed-air and vacuum-air solutions. This synergy benefit is particularly strong with the Energy and MDA (Motion, Drive & Automation) shows, but it also applies to all the other shows at HANNOVER MESSE.” Atlas Copco Airpower n.v. (Hall 26, Stand B32) will be showcasing its GA 90+-160+/GA 110-160 VSD series of oil-injected rotary screw compressors. The series’ integrated variable speed drive (VSD) technology and energy recovery systems yield significant energy savings and reductions in operating costs. They also feature latest-generation oil-injected rotary screw elements for longer service life and trouble-free operation. What’s more, the ES central controller links all compressors and dryers and lowers the overall pressure band to achieve further energy savings. Water condensation is the enemy of industrial compressed-air systems, so it is vital to have effective drying technologies to eliminate water vapor. BASF SE (Hall 26, Stand E04) has such a technology – adsorption drying – which it will be unveiling at ComVac. As used in compressed-air systems, adsorption is where molecules of water (the adsorbate) accumulate on the surface of a solid adsorbent medium. Unlike absorption (where the water permeates into a medium like a sponge), the water is “trapped” on the surface of the medium, leaving the air dry. The DRYPOINT® RA series of refrigeration dryers by BEKO Technologies GmbH (Hall 26, Stand C31) automatically adjust their output in accordance with compressed-air withdrawal (demand), thereby reducing partial-load operating costs by up to 70% compared with conventional refrigeration dryers. The technology has applications wherever compressed-air systems and products require reliable protection from condensates and contamination. Drying is achieved by cooling the air, resulting in condensation which is then discharged with no loss of compressed air. The air is then reheated, reducing the relative humidity of the dried air to below 30 percent. The amount of energy used in this process varies according to the required drying performance, thereby further lowering energy costs and protecting the environment. Meanwhile, at Stand B56 in Hall 26, BOGE KOMPRESSOREN Otto Boge GmbH & Co. KG will be presenting a prototype of its S-4 Optimus rotary screw compressor. The purpose of the S-4 Optimus project is to demonstrate what a quiet, efficient and smart future might look like. When ready, the new series will be even more reliable, intelligent and energy efficient than other commercially available systems. BOGE KOMPRESSOREN will also be presenting an array of standalone devices and components, as well as intelligent machine and central control systems and remote monitoring solutions.
