The successful DELTA BLOWER series from Aerzen has been specially modified for applications in the landfill/biogas as well as also natural or town gas. Customer can select a unit that is optimal for the application from this extensive blower series.
With 10 sizes, the DELTA BLOWER for biogas now covers intake volume flows of 60 m³/h up to 2.500 m³/h and overpressures up to 1.000 mbar.
The heart of the DELTA BLOWERS are positive displacement blowers with three-lobe pistons where the normally usual pulsations are reduced resp. almost completely degraded by a patented pre-inlet channel already on formation. Regarding the applications in the range of biogas, the blower stage is designed with a gastight sealing of the driving shaft. On customer’s request a combined conveying chamber sealing for humid landfill gas as well as Chem-Coat-coating of the rotary pistons and of the conveying chamber is available as special corrosion protection. All components of the unit are installed and mounted on the base support. The cast base support comprises pure metallic, installations completely free from wear with a uniform sound reduction. Pressure and suction silencers show an explosion pressure shock resistance of 12 bar.
A further advantage for the user is the driving motor installed on a hinged plate driving the blower stage via narrow V-belt (antistatic). This conception ensures that the V-belts are always optimally tensioned and a re-tensioning is not necessary after a long periods of use. The extremely compact units are supplied with all accessories necessary for blower operation including control and are ready for immediate application.
Due to the modular design, the standard package has a multitude of possible customized adaptations without high additional expenditure, such as by-pass operation with overflow controller for keeping the discharge pressure constant, pressure protection via limiting valve, by-pass with start-up unloading device, shut-off devices, instrumentation and protection and much more.
With the unique unit concept of the DELTA BLOWER series Aerzen has reached a goal of development that successfully converts the future market requirements today.
