Investments

Machine park renewed and expanded

There have been some major investments in production recently at the location in Aerzen. In the past few months, three new machines have been taken into operation, in order to support high-quality and more efficient production.

The new flat grinding machine
The new machining centre began operations in January.

New flat grinding machine

After more than 20 years of operation, the old Favretto machine has been replaced with a compact flat grinding machine model ZT 715 made by Ziersch. Its task is the grinding of rings, bushings, washers, covers and side plates. 70% of the pieces to be processed consist of steel, 20% consist of cast iron and 10% consist of stainless steel. While the old machine could only manage surface roughnesses of up to 4 μm, the new one reaches 1 μm. The spindle power is now 15 kW and the work surface is even larger. It is remarkable how quietly the new machine runs.

New machining centre

For the processing of housing parts, a new machining centre DMC 160 U duoBlock was procured from Messrs. DMG Mori Seiki GmbH. With this machining centre,in future cylinders and side plates can be manufactured from segment 2. January saw the commissioning and the manufacturing of the first cylinders VM 237 L and suction side plates VM 337 L. Thanks to the 5-axis machining centre, the housing parts can be processed in one clamping. A special feature is the universal milling head with kit motor in heavy-duty version, with a capacity of 52 KW and 2000 Nm.

New CNC turning and milling centre

As a replacement for the FE0178/0179, in November 2014, the new M65 MILLTURN FE 0176 from the manufacturer WFL in Linz, Austria was taken in operation in hall 21. Four identical machines have hitherto been in operation in the production centre for the complete processing of blower pistons and compressor rotors. The new machine was designed for the range of parts in hall 21. The essential difference from the existing machines is the reinforced design of the turning, drilling and milling unit, as well as the use of processing heads when milling with bigger profile cutters. This will considerably reduce wearin the turning, drilling and milling unit, and will increase the machine’s availability.

AERZEN Thailand founded

With the recently opened subsidiary in Thailand’s capital Bangkok, AERZEN is now present in the “Land of Smiles”. Since 3rd December 2014, Mrs. Jittarat Maneewan, who already knows our products very well, has been working as Business Development Manager for Thailand. In her role, she reports directly to Mr. Andy Lim, AERZEN Singapore, General Manager for South East Asia. Opening a new office in Thailand is part of the AERZEN service strategy to always be close to our customers and to be able to support them directly. The co-operation with the present sales partner, Uni Royal International, will continue - in particular in the After Sales range.

Laser-based coupling alignment – efficient and precise

Machines that are optimally aligned have lower operating and maintenance costs. Thanks to precise alignment, the “Mean Time Between Failure” is reduced and machine availability is increased.For this reason, AERZEN applies across the group the laser-based alignment system OPTALIGN smart RS5 AERZEN. This enables the alignment of directly driven machines. The customer benefits are obvious: lower-wear operation, increased machine availability and prevention of production failures. Using this approach, AERZEN expands its service competence. For any questions, just contact our service managers on site, or our specialists in our parent company.

AERZEN further expands its range of compressors

AERZEN has expanded the new Delta Screw E compressor-series to a total of six different sizes: the new models VM 30 and VML 35 cover the lower volume flow range of 330 to 2,590 m³/h and thus supplement the belt-driven packaged unit types. The VM- and VML compressors, with a maximum differential pressure of 2 or 3.5 bar, are optionally equipped with pressure retaining valves, overflow regulators and air-toair aftercoolers, and include cyclone separators and an automatic condensate drain. Specially tailored solutions are also possible.

New concept for service and maintenance trade fairs

AERZEN has developed a new, modular fair stand concept which can easily be adapted to various base areas, and which reflects the new Corporate Identity. The freestanding, portal-like beam construction of this fair stand is designed to attract the attention of visitors from some distance. Therefore, an adequate presentation area is now available for products and services of the AERZEN After Sales Service. We celebrated its debut at this year’s “Maintenance” fair from 25-26 February in Dortmund, Germany.

Automatic re-lubrication devices

Packaged units with high annual operating times may require more service calls for the re-lubrication interval of the electric motors. Therefore, AERZEN has included automatic re-lubrication devices in the After Sales Service Programme.

These systems are driven by electric motors; the dispensers are provided with the necessary power supply by an integrated removable battery.

Cartridges are available in three different sizes and various types of lubrication. The devices can be applied at temperatures from - 10 °C to + 60 °C. Thanks to corresponding programming, the dispensed quantity can be accurately dosed and adjusted to the requirements of the electric motor. Therefore, an efficient and safe lubrication without downtime is guaranteed. In this way it can be ensured that the system is permanently available. Retro-fitting of new AERZEN machine lubrication devices is also possible for existing standard motors.

Aerzen do Brasil celebrated its 15th anniversary

Last year, the team at our subsidiary Aerzen do Brasil celebrated its 15th anniversary: to have been in business successfully for 15 years in the important, but highly competitive Brazilian market, is a great achievement. To celebrate this milestone, all Aerzen do Brasil colleagues, and their families, were invited to a celebration “in the green”.
