AERZEN offers certified safety standards for the pneumatic industry

Product contamination? Not with AERZEN!

There are high demands on blower technology in pneumatic conveying of bulk material. AERZEN has therefore developed a new and certified safety standard.

A new brochure informs about the AERZEN safety standards for the pneumatic industry.

 These expectations are not only caused by the fact that these systems have a key function in the material flow, but are also based on the fact, that the quality of process air is of vital importance. The purity of the conveying air and the final product both influence the quality of pneumatic processes. For manufacturing high-quality products, e.g. in the food industry, pharmaceutical and cosmetics industry, in parts of the automotive industry, the paper and textile industry, but also in sensitive chemical or petrochemical processes, the purity, safety and reliability are decisive. In this context, AERZEN has developed a new and certified safety standard, especially for the requirements in the pneumatic industry.First of all, the oil-free operation should be mentioned. Not only the contamination of bulk material with oil poses a potential hazard here, the contamination of the installed system may be a risk factor as well. AERZEN, being among the world’s leading manufacturers of positive displacement blowers, rotary lobe compressors and screw compressors, has initiated an extensive certification according to ISO 8573 for all series together with TÜV Rheinland. On that basis, an oil-free operation of class 0 had been confirmed and certified for AERZEN blower and compressor packages.

Completely new silencer technology

product purity and safety certificates
100% product purity and safety thanks to certified technology

The AERZEN safety concept goes even further and therefore, the focus is also on the silencer technology. Discharge silencers which are lined with absorption material are still often used for blowers and compressors. However, this insulating material is subject to natural wear. This wear is caused primarily by the high intake temperature of the air and the abrasive wear by the pulsations in the silencer. The absorption material is washed out of the silencer in fine particles and so it gets into the conveying air.As a consequence of this, AERZEN has developed an entirely new silencer technology, which has been successfully patented. The sound level of these reactive silencers is reduced purely by means of air deflection. The advantages are obvious: Process safety and air quality are guaranteed as well as a constant sound pressure level across the entire life cycle, as no wearing material is used. Furthermore, the pressure losses in the silencer had considerably been reduced compared with conventional solutions. The result is increased energy efficiency!

No external spark arresters necessary

Often overlooked in pneumatic conveying systems is that blowers and compressors may produce sparks in case of malfunction and that, fed into the conveying pipe (pressure conveying), these sparks can ignite dust-air mixtures. The patented silencers made by AERZEN also play an additional key role, as thanks to the internal air deflection, the reactive silencers also serve as spark arresters. An innovative solution, inspected and certified by the TÜV. When using AERZEN blower and compressor packages, external, on-site spark arresters are not needed anymore, offering a great advantage for plant manufacturers and plant operators as well. As besides the ATEX compliant safety, the AERZEN solution saves on investment costs and energy costs sustainably, as pressure losses caused by downstream spark arresters can be prevented.Furthermore, AERZEN offers a solution portfolio for almost all ATEX zones which is unique for a wide range of applications and performances. The AERZEN packages Delta Blower, Delta Screw and Delta Hybrid are tailored specifically to meet the requirements of categories 2 and 3 for dust and gas zones in accordance with the European Machinery Directive 2014/34/EU. Explosion protection for systems in accordance with ATEX directive 137 (1999/9/29 EC) has also been taken into account. The absolutely oil-free air technology, free of absorption material, made by AERZEN guarantees 100% product purity and 100% ATEX safety in pneumatic conveying of bulk material.

inauguration of the Aerzen Asia site

Aerzen Asia opens new head office in Singapore

On 25th August 2017, Aerzen Asia officially opened its new head office for the Asia Pacific(APAC) region in Singapore. Customers, partners, suppliers and colleagues of the region and fromGermany participated in this event. Klaus-Hasso Heller (CEO AERZEN), Chuck Lim(Vice President Aerzen Asia Pacific) and StephanBrand (Vice President Marketing & Product Management)gave very inspiring and encouraging speeches about the importance of team spirit, co-operation, friendship and future orientation for the team in Asia. In his speech Chuck Lim emphasised that the term “team” stands for“Together everyone achieves more.” So, each member of the team is an important piece of the puzzle.Later on, during a ceremony, symbolically the ribbon for the inauguration of the site was cut and they had a glass of sparkling wine. A traditional lion dance, asking for happiness and prosperity followed. After lunch, they had a guided tour across the premises. On the first floor of the two-storied building of Aerzen Asia the offices are located. At the ground floor there is a workshop for the After Sales Service. Here the focus is on overhauling and repairing blower and compressor stages. The training centre for many technicians in the AERZEN service team in theAPAC region is also located there. The special facilities and equipment are on the same level as at the parent company in Germany.With its new head office Aerzen Asia is well prepared for the challenges of the expanding business environment.

Application brochure

Applications with water vapour: new brochure

The know-how and experience that AERZEN has gathered over the decades in almost all types of application are particularly strongly reflected in water vapour and vapour recompression processes. The compression and transportation of water vapour is a complex process, which can only be achieved through the use of special technology and finely-tuned processes. In this context, water vapour is often used as a medium to provide heat in boiling, evaporation or distillation processes. This method can also be used during drying processes and for heat production in the chemical and foodstuff industries. The new brochure “Applications with water vapour” (A5-010-00) provides information about the AERZEN product portfolio in terms of water vapour compression, which includes a wide range of special blowers and compressors, combined with extensive application expertise. Please have a look at this new brochure.

First Business-Event for Aerzen North Africa

Aerzen North Africa has moved into new premises: to mark the occasion, the subsidiary’s first business event took place on 9th August 2017 in Cairo. 30 customers and plant manufacturers from the wastewater, cement, steel and chemical industries were invited to the Hotel InterContinental. After welcome speeches from Managing Director Dr.-Eng. Ahmed Yehia and Steffen Glindhaus (Director, Middle East & Africa), employees introduced the team, products, applications and the service orientation of Aerzen North Africa. The establishment of Aerzen North Africa and the move into new premises mark an important step for the AERZEN Group, enabling the company to provide support for many customers and installations in North Africa through its own, local sales and service network.

Order No. 1 for Aerzen Argentina

Adrian Dubini will always be remembered at Aerzen Argentina. The Managing Director of Dubini Automación placed the first order with the new AERZEN subsidiary, founded on 1st May 2017. In appreciation, Alejandro Knoop, Director Aerzen Argentina, invited his first customer to join him for a photo. Mr. Dubini ordered a positive displacement blower Delta Blower GM 15 L. This assembly, from AERZEN series Delta Blower Generation 5, will be used for pneumatic conveying at a manufacturer of pet food and veterinary products.
