Helsingør History
Siemens Turbomachinery Solutions (then HV-Turbo A/S) was acquired in beginning 2007 by Siemens together with the KK&K Group (Kuehnle, Kopp & Kausch).
The KK&K Group was renamed to “Pre-defined Compressors and Fans” (abbreviated to “PCF”) and integrated with the Oil & Gas Division of Siemens.
The HV-Turbo Group was renamed to “Municipal and Industrial Application” (abbreviated to “MIA”) and included in the PCF Group as E O C&S PCF MIA.

In the secondary treatment phase waste water is treated by means of bacterial breakdown of the dissolved biological waste.
In order to foster this bacterial break-down, the oxygen level of the waterneeds to be increased. Aeration is the process by which the area of contact between water and air is increased, either by natural or mechanicalmeans, resulting in air being suspended in water.

Siemens Turbomachinery SolutionsDual Point Control with STC-GO series
Air flow = f(n)Diff. pressure = f(n²)
Impeller speed = n
Single Point speed controllimits the turndown range as the pressure drops much faster than the flow by reduced speed. In order to reach a decent turndown, it is necessary to design the compressor for a much higher value with the result of overall lower efficiency.
Independent regulation of capacity and head:Capacity regulation via variable diffuser vanes: diffuser vanes are gradually closed, reducing the nozzle area, whereby a continuous turndown to 45% by keeping the maximum efficiency is achieved.
Head regulation: Inlet guide vanes (IGV) are adjusting the performance map acc. to fluctuations in temperature/ humidity and pressure changes
