Hybrid meets Hybrid – for purest coffee enjoyment

FOR OVER- AND NEGATIVE PRESSURE

From storage of the green coffee up to packaging machine: the roast machine manufacturer Probat in Emmerich relies on Delta Blowers and Delta Hybrids for the pneumatic conveyance of the black gold.

Two Delta Blowers Generation 5 and one Delta Hybrid generate the conveying air for Probat.
Plant Engineer Probat:»Since 1996 we have collaborated with Aerzener Maschinen-fabrik, as products, advice and service completely fulfill our expectations. Therefore, redundancy units are no longer necessary for Aerzen units in our roasting equipments.«

In September 2012, Probat opened a new Research – and Technology Centre. There, the conveying air required in the roasting machines is generated by two Delta Blowers Generation 5 and one Delta Hybrid. Upon storage of the green coffee into silos with overpressure between 1,000 and 2,000 mbar, the Delta Blower is used, also during transport to the roasting machine with overpressure.

The Delta Hybrid is responsible for transport of the particularly sensitively roasted beans to the roasted coffeesilos and to bagging station with negative pressure as well as for transport to grinding plant with overpressure. The Delta Hybrid unit generates a negative pressure of 300 mbar on suction side as well as an overpressure of 600 mbar on discharge side. Therefore, a conventional blower unit could be replaced acc. to the principle “Two become one”.

Again, two Delta Blowers transport the ground coffee to the ground coffee silos and to the packaging machines with negative pressure. As an alternative, how- ever, also Delta Hybrids can be used. The required differential pressure is decisive for the selection dependent on the piping length and the specific energy advantages of the Hybrid.

CLOSE CO-OPERATION

All Aerzen units are fully automatically integrated in the process of the roasting equipment and are switched via a super-ordinated intelligent SPS control depend- ing on the program.

The respective blower units are driven with a constant volume flow whereby the pressure is built up depending on conveying capacity and pipe length. Thanks to a bypass solution, Aerzen had developed together with Probat, a part of the volume flow can be led back from discharge to suction side for the overpressure units.All units are supplied with country- specific documents and in operator-specific designs up to special colourings.

DELTA HYBRID AND JUPITER HYBRID

Aerzener Maschinenfabrik and Probat are a perfect match: for reasons of their foundation and the Hybrid, that both companies have within their scope of supply, now “A good omen for a successful future for both sides”, comments Michael Engels of Probat.

ISO-Certificate for Aerzen Mexico

At the end of December 2012 Aerzen Mexico was certified in accordance with ISO 9001-2008. Sales, after- sales and maintenance of blowers, compressors and gas meters all comply with the quality management standard. The certificate is valid until the end of 2015

New sales engineer for the Asia-Pacific region

In November 2012, Axel Wehling became the new sales engineer for the Asia-Pacific region. Hismain responsibility, together with Regional Manager, Chuck Lim, is to expand Aerzen’s business across the region. As a graduate in technical business administration, and from his time working in the capitalgoods industry, Wehling has international experience in projects involving multiphase positive displacement pumps and systems in the oil and gas sector.

Delta Hybrid D 152 in field testing

The extension of the series Delta Hybrid range of products is progressing: in the meantime, the development of the next size D 152 has been completed. This machine can be used with negative pressure up to -700 mbar and with positive pressure up to 1,500 mbar at a volume flow of up to 9,000 m3/h.The first machines D 152 S and D 152 H for field testing have already been supplied and commissioned. Field testing will continue until the end of this year. Supply of the first serial machines D 152 S and D 152 H is scheduled for early 2014.

Aerzener Maschinenfabrik is a Trusted Partner

In the middle of last year Aerzener Maschinenfabrik gained the so-called AEO- certificate (“Authorised Economic Operator”) and was thus confirmed as a highly trusted trading partner within the European Union.The advantages of gaining this certification include fewer goods controls and accelerated customs procedures. Since 1st July an agreement has come into force between the U.S. and the EU, which simplifies imports and exports considerably. Consequently, the U.S. and the EU will mutually recognise their authorised economic operators - with “C-TPAT” in the U.S. which corresponds with “AEO” in Europe.Companies will benefit from quicker inspections and lower costs in respect of customs clearance.

Water-Injected Compressor Series Expands

For generating absolutely oil-free compressed air, Aerzener Maschinenfabrik has developed the new VMW-water stage. New, single stage VMW water stages working up to 13 bar have already been tested successfully under practical conditions and in continuous hard operation. Besides considerably improved efficiency they also offer significantly reduced maintenance expenditure, and are available for the time being for driving capacities of 45 to 110 kilowatts, and for maximum intake volume flows of between 13.4 and 17.2 cubic metres per minute. The new Aerzen VMW-water stages were designed exclusively for directly drive. They work at speeds of 1,500 to 5,000 rotations per minute and can be used in plants with constant speed as well as in demand- controlled plants.

New Aerzen subsidiary in Taiwan

On 1st January 2013 Aerzener Maschinenfabrik established a new subsidiary in Taiwan. All orders and financial transactions of Aerzen Asia Singapore - Taiwan Representative Office, so the entity’s official name, are settled through Aerzen Asia Pte. Ltd. in Singapore which is the 100 per cent owner of the new entity. A new country manager is now located in Taipei- he replaces C.C. Lin of Tiphery Corp. who has coordinated business in Taiwan for Aerzener Maschinenfabrik for the past 20 years. With the establishment of this new entity, Aerzen will significantly strengthen its presence in Taiwan.

Improved performance: Delta Hybrid D 98 V

The requirements for Aerzen machines increase continually – this is due to the constantly increasing fields of application. Aerzener Maschinenfabrik received an order to design a Delta Hybrid-stage which can be used in negative pressure up to-900 mbar.Aerzen met the challenge and developed the Delta Hybrid D 98 V. In this case the “V“ stands for “Vacuum“. The design has been completed and the first field tests will start shortly. In particular,the stage can be used in both stationary as well as in mobile areas.Another advantage, particularly for vehicle manufacturers, is the weight-performance ratio. In the past, a screw compressor or a blower with pre-inlet could be used for a negative pressure of -900 mbar. With the Delta Hybrid D 98 V a negative pressure up to -900 mbar as well as an overpressure of 1.500 mbar at a volume flow up to 5.400 m3/h can be realized.This means that, Delta Hybrid D 98 V combines the advantages of the blower with preinlet and those of the screw compressor – with a low space requirement.

New Managing Director at Aerzen Switzerland

Marcel Strotz will take over the management of Aerzen Switzerland as of 1st April 2013. Strotz, who has been working at Aerzener Maschinenfabrik since December 2012, will replace longtime Managing Director, Vito Jahn, who is retiring after many years of loyal service.

New Managing Director at Aerzen do Brazil

Rainer von Siegert has become the new Managing Director of the Brazilian subsidiary, Aerzen do Brazil, as of 1st January 2013.Von Siegert has been working for the Aerzen Group since August 2012,when he assumed the MD role on a temporary basis following a sudden change in management at the Brazilian subsidiary.

Poland voted Delta Hybrid “Product of the Year”

The Polish specialist journal “Ulrzymanie Ruchu” (Ger. plant engineering) has voted Aerzen rotary piston compressor Delta Hybrid “Product of the Year 2012” in Poland.In the first phase, a jury of four had assessed all the submitted products. Then, in the second phase, the readers of the print and online edition decided on the awarding of the coveted title. This positive assessment of Delta Hybrid was primarily due to its energy efficiency.On 20th March representatives of Aerzen subsidiary in Poland accepted theaward on the fair AUTOMATICON in Warsaw.
