Negative pressures of down to –0.95 bar with further developed Aerzen Rotary Lobe Compressor Delta Hybrid

26.10.2016

Thanks to the new rotary lobe compressor series Delta Hybrid, Aerzener Maschinenfabrik implemented very successfully in 2011 a symbiosis between positive displacement blowers and screw compressors in the volume range of 10 to 100 m³/min. Thanks to this new special machine Delta Hybrid size D 98 V Aerzen could decrease this maximally possible negative pressure still further down to –950 mbar.

The most important features of this new series are as follows: Increase of energy efficiency up to 20% and extension of the application fields. The pressure ranges of the positive displacement blowers could be increased from 1000 mbar to 1500 mbar and regarding negative pressure from -500 mbar to -700 mbar. Thanks to this new special machine Delta Hybrid size D 98 V - the first type of this developed series - Aerzen could decrease this maximally possible negative pressure still further down to –950 mbar and is therefore, close to the vacuum range. This increased performance is possible by a more intensive and internal cooling of the compressor stage via additional pre-inlet channels.

According to the motto “heavier, faster and more efficient”, this new machine type offers clear advantages by the increased negative pressure: Transport of heavier materials, via longer distances and/or with higher speed. Résumé: In any case, the efficiency of the loading and unloading increases. The new Delta Hybrid may produce overpressures up to 1500 mbar as well as negative pressures down to -950 mbar and is, therefore, the perfect rotary lobe compressor for a wide range of operations. This compressor is suitable for mobile resp. stationary use. This starts with the loading and unloading of the trucks. For the mobile application the machine can be mounted directly on the vehicle and is driven by the truck motor or electrically. However, it can also be mounted stationary at the place of installation with fixed installed electrical drive and deliver conveyed air with over- and negative pressure for the loading and unloading of vehicles as well as for the general pneumatic transport tasks. The packaged unit can reach a volume flow of 5700 m³/h max. D 98 V is delivered with the electrical oil demister. A separate oil reservoir and an oil cooler are necessary for operation above certain oil temperature (from 120 °C), which corresponds to a negative differential pressure of -800 mbar.
