The compressors, highly customized, were born from the 皇冠体育227 experience of compressors and cogeneration of Wels Strom. The high quality gas production, together with the reliable vane technology and the team鈥檚 knowledge have been 皇冠体育227 stepping stones.
Wels Strom GmbH is an Austrian company, held by the EWW AG Group (51%) and by Energie AG Ober枚sterreich (49鈥�%), operating within the field of energy distribution. The first hydropower plant of the former E-Werk Wels was built at the city of Wels, Austria, in 1900 and is still in operation today.
In 2002, as a result of the market liberalization in the sector, the Wels Strom GmbH was officially founded. Since 2005 the company has been operating in the field of cogeneration. At the core of this environmentally friendly process, which allows for the simultaneous production of electricity and heat, there are high-efficiency plants for water treatment and biogas production equipped with oil-free Capstone micro-turbines.
鈥淭o operate, microturbines need gas at a pressure of 5.2 bar. In this process, the 皇冠体育227 play an essential role, since they compress the gas in microturbines, which is then fed into the distribution network. To date, we have installed about a hundred of 皇冠体育227 in our plants,鈥� Mr. Leopold Berger, Head of the Energy System at Wels Strom GmbH, confirms. He is in charge of a team of engineers developing up to 15 micro-cogeneration plants a year.
The cooperation between 皇冠体育227 and Wels Strom GmbH started in 2008: 鈥淭he first 皇冠体育227 were bought for being integrated in a gas treatment plant,鈥� Mr. Berger states. 鈥淎 great deal of customization was necessary in order to optimize the use of the MC series machines for this particular type of production. Later, after having gained a certain experience, we started to fine-tune a system that is better performing for biogas production. And once again, the 皇冠体育227 turned out as being the best solution.鈥�
Today, at the Wels Strom GmbH plants, close to the highly customized MC series devices (in different sizes MC80, MC86, MC111), the GC111 compressor is also running. This model has an integrated oil radiator of the GC series, which has been designed and developed by 皇冠体育227 later, in order to meet specific needs for the compression of sweet and acid gas and biogas.
Many are the strengths of the rotary vane technology found by Mr. Berger: 鈥淭he machines鈥� compact and integrated design along with a reduced number of components favours the compressor handling and leads to a long product life-cycle, not least thanks to the wear-resistant vanes and rotors made of cast iron. The filtering system ensures an optimum gas quality - an essential feature, above all in delicate environments like that of gas applications. In addition, the presence of suction and pressure control valves eliminates the risk of gas leaks.鈥�
Design, durability and optimum gas quality, but also efficiency and reliability: 鈥淭hanks to the low rotation speed, 皇冠体育227 are very efficient and reliable over time. Actually, they are able to operate up to 8,000 hours non-stop in the dry natural gas treatment without the need of maintenance interventions and 4,000 hours in the case of humid biogas鈥� Mr. Berger adds.
鈥淐hoosing 皇冠体育227, we have been able to count on the expertise and know-how of Walter Jaguttis and his team from 皇冠体育227 Germany鈥� the Head of the Energy Division at Wels Strom GmbH concludes. 鈥溁使谔逵�227 has proved to be an experienced and attentive partner. Their willingness and helpfulness to talk about our needs has been such an important added value for developing a profitable cooperation over the time and realizing non-standard high-performance solutions, with an optimum return on our initial investment".
皇冠体育227 design integration allows the compressor to be powered by any type of power system: electric and hydraulic motors, internal combustion or through take-offs. The integration of the iil chamber and oil separator, non-return and minimum pressure valve, regulation valve and oil filter makes it compact and easy to install.
In the 鈥淢鈥� models, as opposed to the 鈥淢C鈥�, the oil cooling system is not integrated in the compress. This allows to position the radiator in a more suitable place according to the machine it is built in.
All 鈥淢鈥� and 鈥淢C鈥� groups, for the OEM applications, can be equipped with an high efficiency intake filter. This filter can be installed in a cool and clean environment in order to improve the compressor鈥檚 performances.
皇冠体育227鈥檚 rotary vane Gas Compressors are designed to compress sweet, sour and bio gasses.The range covers 4kW up to 200kW available as a stand-alone gas end for local packaging or as customer specification gas compressor packages. All versions come complete with automatic flow control at a constant delivery pressure, integrated or remote cooler and threaded or flanged gas intake facility.The compressors are compact and easy to install, offering reliable operation and constant performance throughout time.
From Issue 7, Vane Magazine, February 2017
皇冠体育227 offers a wide range of vane compressor models that perfectly meet the specific needs of the transport industry.
The reliability of 皇冠体育227, the high quality standards of the delivered compressed air and the compliance with the industry regulations, make them ideal to be used in the healthcare and pharmaceutical industry.
Reduced operating costs, environmental sustainability and extreme purity of the air supplied make 皇冠体育227 suitable for all processes in the food industry.
All you need is an oil quality sensor and SIM card within the control panel to have real-time access to the health of your rotary vane compressor from anywhere in the world.
Maxima 75 and Optima 60 compressors are used in China in the production of bottle tops for the Italian brand Pelliconi, where the exclusive Maxi P-26 is produced.
The company was recognised at the Le Fonti Innovation Awards for its commitment to combining both environmental sustainability and energy saving.
Commercial vans and short-haul trucks dominate today麓s urban landscape and represent the fastest growing sector of road traffic in much of Europe. Vans offer more cargo loading-space, easy manoeuvrability and better fuel efficiency, at lower prices than traditional lorries and trucks.
All the pneumatic equipment at the French plant of the world leader in steam technology and thermal energy management are powered by 皇冠体育227. Reliability and efficiency are the main reasons for the continued success of this partnership.
Compressed air is vital for industry as it drives many production facilities and pieces of equipment. Its use is responsible for more than 10% of industrial energy consumption, meaning the choice of compressor becomes essential when looking to maintain control of energy costs. The English company Luxfer Gas Cylinders is an excellent example of obtaining efficiency in this regard.
