| At the heart of the DELTA BLOWER are positive displacement blowers with three-lobe pistons where the usual pulsations are reduced resp. almost completely degraded by a patented pre-inlet channel. For biogas applications 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 also available as special corrosion protection. All components are installed and mounted on the base support. The metallic cast base support achieves a uniform sound reduction without absorption material over the whole speed range. Moreover pressure as well as 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 design means that the V-belts are always optimally tensioned and a re-tensioning is not necessary, after a prolonged period. The extremely compact units are supplied with all accessories necessary for blower operation incl. control and are therefore ready for immediate application.
Due to the modular system beside the standard concept a multitude of customized adaptations are possible 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 as well as many more.
With the unique concept of the DELTA BLOWER series Aerzen are proud to be delivering future market requirements today.
