Aerzen focuses on tailor-made engineering

For this, however, the compressed air packages must give up their role as black boxes. The decreasing system boundaries therefore create new possibilities for integration and regulation. At the same time, completely new questions arise, most of all in engineering - especially in terms of interfaces and communication. All in all, this leads to increasing specialisation, resulting from its standardised modular system, which offers possibilities for customised solutions.

Partnership

With this background, Aerzen is strengthening the role of its subsidiary RKR as a strong engineering partner for customised applications. Typical tasks here result primarily from questions relating to communication, the control network and new drive options. Instead of an electric motor, a compressor can be effectively driven by a compact turbine if process steam is available in the plant anyhow. This saves the electric drive - and thus reduces the electricity bill. A diesel drive is also conceivable. Aerzen offers both 2C series in water- or air-cooled design for volume flows from 166 m³/h to 9300 m³/h in a pressure range of 4 to 10.5 bar (g).

Open systems integration

At product level, Aerzen meets the increasing individualisation with open system integration, modular basic components, as well as variable mechanical and electronic interfaces. Another example of customised specialisations are the proven oil-injected VMX screw compressors. The VMX 250G series, originally developed from customer requirements, today comprises 10 different types with drive speeds from 1800 to 3000 rpm for conveying capacities between 1200 and 3000 standard cubic metres per hour. The compressor stages can be individually adapted to this solution. The same applies to the drive, which does not necessarily have to be of electrical nature.

At the recently held Comvac show, Aerzen presented the highly integrated combination with a directly coupled CAT diesel engine. The engineering in this case was taken over by the Aerzen subsidiary in the Netherlands. In general, all VMX screw compressors are designed for electric and combustion motor drive, and for the use of frequency inverters.
