Cummins is the world's largest independent engine manufacturer. Its product line includes diesel and alternative fuel engines, engine critical components (fuel systems, control systems, air handling, filtration systems, and exhaust gas treatment systems) and power generation systems. Headquartered in Columbus, Indiana, USA, Cummins provides services to customers through its network of more than 600 distributors and over 6,500 distributors in more than 190 countries and regions. In 2011, Cummins was selected for the seventh consecutive year in the Dow Jones Global Sustainability Index with its outstanding performance in economic development, environmental protection and social responsibility. Among the world's largest 2,500 companies, only the key indicators of sustainable development The top 10% of the top ranked players can be selected for this list.
In 2008, in the Yizhuang Development Zone in Beijing, Cummins Emissions Processing Systems established a new production base and R&D center, which mainly produces and develops urea injection systems for diesel commercial vehicles. At the beginning of the construction, Cummins has always implemented the requirements for safe production and stable operation. During the open tendering process for key equipment including air compressors and dryers, they all strictly followed the standards and performed assessments one by one. More importantly, Cummins has also fully considered the goal of energy-saving and emission-reduction in the manufacturing process as a company that adheres to sustainable development of productivity. In the project's air compressor tender, Cummins made comprehensive considerations, and finally selected Atlas Copco among the three bidding companies and purchased Atlas Copco GA75VSDFF variable-frequency injection screw compression. machine.
The Atlas Copco GA series of on-site air compressors uses Atlas Copco's patent-pending fuel injection screw transfer and high-efficiency, maintenance-free drive, designed and manufactured in accordance with ISO9001, ISO14001 and ISO1217Ed3AnnexC requirements. The test ensures long-term, trouble-free operation with the lowest operating costs. Today, the energy consumption of compressed air may exceed 40% of the total energy consumption of the enterprise. Atlas Copco GAVSD inverter compressor can accurately meet the fluctuation demand of users for compressed air and adjust the gas production volume according to the actual gas consumption. Reduce the energy consumption of unloading, minimize the energy consumption of the compressor and reduce the energy consumption by up to 35%! The new Elektronikon® controller is equipped with powerful control and monitoring capabilities to increase the operating efficiency and reliability of the compressor. And, Elektronikon® maximizes energy efficiency by controlling the main motor's operation and controlling pressure in a smaller pressure zone! The new built-in refrigerated dryers in the GAVSDFF series feature the most environmentally friendly R410A refrigerants for superior refrigeration performance. At the same time, the pressure is reduced to match the energy-saving operation function, the energy-saving effect is unparalleled, and the global warming potential of GWP is more effectively reduced!
"For Cummins's production line, compressed air is a power source that is equal to electric energy. Therefore, the selection of air compressor suppliers is very cautious. You remember that at the time, among the three companies that were finalists in the tender, there was a foreign brand of air. The press manufacturer is the original supplier of the old factory, and it is an enterprise in the list of suppliers to our group, but according to the comparison of the product quality, safety, stability, and especially the energy-saving effect of the VSD inverter compressor, Atlas Copco's GAVSD variable-frequency oil-injected screw compressors stand out from the crowd, said Mr. Jiang Peng, Purchasing Specialist at Cummins Emissions Processing Systems (China) Co., Ltd.
"Yes, Atlas Copco is adhering to the design concept of minimizing operating costs and maximizing profits in the production process. Through continuous technological innovation and superior products, it will create greater value for customers." Atlas • Chen Yanzhe, senior sales engineer of the Industrial Gas Division of COPC, continued, “As with Cummins, Atlas Copco has been selected as a member of the global Dow Jones Sustainability Index for many times and is always committed to achieving sustainable productivity!â€
In 2011, Cummins Emissions Processing System's Beijing plant expanded its production capacity and selected Atlas Copco's GA75VSD variable-frequency oil-injected screw compressor again, which is an affirmation of Atlas Copco's product quality and after-sales service.
Cummins continues to develop advanced power products to improve fuel economy, while meeting and surpassing the increasingly stringent engine exhaust emission and noise standards worldwide. The forthcoming national standards for light diesel vehicles on July 1, 2013, and the five national standards expected to be introduced during the year will be opportunities for the development of highly efficient engines and emission systems.
