Sits, fits, saves AERZEN concepts for gas compression in the process gas- and refrigeration industry For optimal conveyance and compression in the process gas and refrigeration industry, individually adapted solutions are decisive. Therefore, AERZEN works very closely with the customer in the conceptual phase. VR series works completely oilfree and offers the possibility of water injection. VR series The positive displacement blowers of series GQ are also used in power plants.AERZEN has been supplying blow- ers and compressors for the world- wide process gas and refrigeration industry for more than 60 years. Its cus- tomers include companies in the chemical and petrochemical industries, the steel and soda industries as well as biomethane gas producers. Due to the presence of partly ignitable, or toxic, gases, the units are of a specially high technical tightness. Furthermore, they are adapted to the guidelines required by the customers (for example, ATEX-specifications and Ex certifications). Three compressor systems The following series are available for a tai- lor-made solution. Oilfree compressing positive displacement blowersSeries GR for differential pressures of up to 1,5 mbar and intake volume flows from 100 to 50.000 m3/hSeries GQ for differential pressures of up to 1,5 mbar and intake volume flows of 15.000 to 100.000 m3/hScrew compressors, oil-injected compression:Series VMY 36 (Refrigeration and process gas) for differential pressures, single-stage, to approximately 20 bar and intake volume flows from 500 to 8.900 m3/hSeries VMY 56 (Refrigeration and process gas) for differential pressures to 25 bar and intake volume flows of approximately 300 to 2.700 m3/hScrew compressors, oilfree compression:Series VR for differential pressures to 52 bar and intake volume flows of ap- proximately 650 to 120.000 m3/hPositive Displacement Blowers of series GR The two-lobe process gas compressors of series GR work according to the positive displacement principle, and can automatically adapt to changing operating conditions. Depending on process requirements, AERZEN uses nodular graphite casting, steel casting or stainless steel casting materials as well as for the rotors. Moreover, individual sealing variants are available for the conveying chamber, which is separated by a neutral room from the oil chamber. Due to their specially robust type of construction, the compressors are insensitive to contaminations in the gas. For cleaning and cooling, water, as well as solvent, cleaning agent or cooling medium, can be injected Positive Displacement Blowers of series GQ The units of series GQ also work according to the positive displacement principle and can automatically adapt to changing operating conditions. Moreover, they are relatively insensitive to contaminations in the gas. For cooling of the gas, and for clean- ing of the conveying chamber, water can be continuously injected. The units have to fulfill particularly high requirements during their application in central power stations, where they are used for compression of water steam in secondary circuits. Series VMY in the refrigeration industry AERZEN refrigeration units of series VMY are used in closed cooling circuits and enable a performance adaptation between 20 and 100 percent with their integrated volume flow control. As a result, the com- pression of gases, hydrocarbons, ammonia, helium and carbon dioxide can be achieved particularly economically. The oil injection makes the compressors insensitive to fluctuating volumes, temperatures and pressures. Integrated oil separation systems reduce the residual oil content to 1 up to 5 mg/m3. Series VMY for process gas compression Screw Compressors of series VMY are used for compression of, amongst other things, natural gas, inert gases, hydrocarbons and further process mixed gases. Through inte- grated oil separation systems, residual oil contents of 5 to 1 ppm can be reached at battery limits. Oilfree compressing series VR With their oilfree working method and the water injection option, screw compressors of series VR can be used for gases with fluctuating molecular weights, contaminations and a tendency to polymerise as well as for processes, which must not include any oil. The water injection serves to cool down gases to admissible operating temperatures. Temporarily, an injection of solvents is also possible. For this purpose, the cleaning effect of injection water and purge water leakages applies, where deposits of gas contaminations and traces of polymerisation on rotors and housing walls can occur. To develop solutions jointly Gas compression in the process gas and refrigeration industry requires individual solutions. This is exactly what is developed by AERZEN, together with the plant supplier and operator. This leads to tailormade products which, are, moreover, robust and energy-efficient, and can have a lifespan in excess of 30 years.
Expanded customer support In order to expand the support that we provide to our end users in the wastewater domain, AERZEN has hired three new sales and service employees for our sales offices “Nord“ (Walsrode), “West“ (Velbert) and “Mitte/Süd“ (Kahl and Elchingen). These three colleagues will be responsible for contacting our end users and supporting them in case they have any sales-related questions, or questions about our services. In order to be prepared for this, the new colleagues completed a training programme between mid-March and the end of April, where they learned about the comprehensive service product portfolio, as well as about internal processes, procedures and contact partners within AERZEN after-sales service
New management at Aerzen Turbo Robert Janson, who started as Technical Manager at Aerzen Turbo in March 2015, was appointed as the new Managing Director of Aerzen Turbo in Korea on 1st June 2015. He succeeds Steve Won, who has begun his well-deserved retirement. Janson has many years of experience in managerial positions in mechanical engineering, as well as in international trading companies. In addition, Stephan Brand, Director Turbo Business in the head office, was appointed to the management of Aerzen Turbo, in order to strengthen international team-work.
The first children’s book about AERZEN Hamelin’s art school under the responsibility of artist Natalia Ovodkova contacted AERZEN some months ago, asking whether the school may create a book about the company. AERZEN was happy to support this request. Children and young people between 5 and 14 years have been painting ambitiously for many weeks now. AERZEN photos and brochures have served as a useful guide for the young artists. An exciting story will arise around the photos. Visiting AERZEN on 19th March helped the talented youngsters to gather many live impressions. The book is expected to be published in autumn 2015.
Aerzen North Africa LLC founded After a long and successful co-operation with Promotrade as our representative for the Egyptian market, AERZEN has had a new subsidiary in North Africa since February of this year: this is Aerzen North Africa LLC which is based in Cairo, and is a subsidiary of Aerzen International Sales GmbH, which holds 90 % of the shares in the company, with Promotrade holding the other 10 % of the shares.At present, the team consists of five employees and is responsible for Egypt, Libya, Sudan, Eritrea, Lebanon and Jordan.
New rotary lobe compressors for negative pressure applications Rotary lobe compressors in the successful Delta Hybrid series are now available in the new “E type” construction for a pressure range of up to -700 mbar. As conventional positive displacement blowers are limited to a maximum differential pressure of -500 mbar, expensive vacuum pumps had to be used for lower pressure ranges. The new E-series remedies this situation, reduces costs and opens up new application possibilities in the field of vacuum conveying - for example in foodstuff technology, plastic granulate pneumatics and in the chemical industry. The advantages for the operator include reduced investment costs, higher energy efficiency and greater flexibility.
