Aquatec Maxcon is the agent for Siemens Turbomachinery Equipment (STE) in Australia and New Zealand. We supply single stage centrifugal compressors both as a traditional geared unit, or the latest technology high speed, oil free, direct driven unit. The unique design of the STE blowers means turndowns of 45% can be achieved with the potential of 35% turndown avaliable in some cases without any losses in efficiency. Flows range from 1,000m3/hr up to 100,000m3/hr are avaliable with differental pressures up to 200kPa make them ideal for wastewater treatment. With over 150 blowers installed around Australia and New Zealand since 1986 and over 8000 blowers worldwide. Aquatec Maxcon has the experience and expertise required to engineer customised solutions for all aeration challenges.
Siemens Turbomachinery Equipment (STE) are the leading manufacturer of aeration blowers in the world today. Their advanced design techniques and use of modern materials and manufacturing processes result in highly efficient designs which provide sustained power savings and stable, smooth running, reliable operation.
The unique Dual Point control process allows to independently regulate the flow and head of the compressor, giving superior efficency at design and especially off design conditions. The control management system operates automatically and simultaneously the position of the Variable Diffuser Vanes, and Inlet Guid Vanes, or VSD.
The compressor flow function is managed through the diffuser vanes, which increase or decrease the airflow path exiting the impeller wheel, allowing a step-less turndown range from 100% to as low as 35% in some cases. With almost no efficentcy losses. The compressor head function is controlled by either moving the Inlet Guid Vanes, or through a VSD. The control methodology maintains the isentropic efficency at its maximum relative value across a wider range of flow, pressure, and temperature conditions.
The core of the compressor is the impller, which is machined from a solid forged piece of high-grade aluminium alloy and is statically and dynamically balanced.
We can provide different impller sizes for customisation of flows and pressures to suit all our customers requirements
The application of airfoil bearings results in improved efficency, thanks to reduced friction , and exceptional long life with minimal maintenance since no lubricating oil is requied. The latest generation of airfoil bearings are rated for 30,000 starts and stops, which equates to over 20 years.
|Type S||Use outlet diffusers for capacity regulation from 100% to 45% without throttling.|
|Type V||Use inlet, pre-rotating guide vanes to reduce power consumption under conditions of reduced pressure or inlet temperature and for capacity control from 100% to 45%.|
|Type SV||Uses both outlet diffusers and inlet, pre-rotating guide vanes to eliminate excess power draw under conditions of reduced flow and reduced head.··By far the most energy efficent system on the market today.|
The latest form of dual point control replaces the pre-rotating inlet guide vanes with VSD.··This option is equally efficent as SV with a reduction in capital cost.··Suitable for smaller units only.
Each blower assembly is fully tested in accordance with ISO5389 to ensure that all specified duty conditions can be met. Works tests are usually made with the blower's own drive motor and can be witnessed if required.
Overlapping in the flow rangers because of the 45% turndown means there are no “black holes” in flow capacity ensuring smooth and efficent aeration is provided.

Aquatec Maxcon have invested in specialised training for the STE blowers. Many of our Engineers and Technicians have visited the STE factory in Denmark and participated in Mechanical, Electrical and Control System training.
We are avaliable for planned and unplanned maintenance, troubleshooting, and service work.
We also supply genuine spare parts.
