NEW! Turbo Blower Generation 5

Both positive displacement and turbo machines are used in sewage treatment processes. The experienced application specialist Aerzen Machines Ltd. now offers both technologies from one single source. Therefore, plant operators can rest assured to receive tailor-made solutions from Aerzen.

The new performance category is:
Aerzen Turbo Blowers Generation 5

Today, energy efficiency is a mega trend. The more energy is needed the more action is required, and the highest potential savings can be achieved.

The turbo blower Aerzen Turbo Generation 5 is designed for high intake volume flows from 4.000 m³/h to 13.200 m³/h. The speed-controlled and oil-free machines offer decisive advantages in terms of high performance and efficiency in waste water treatment.

Aerzen Delta Hybrid - Energy efficient blower and screw compressor solutions

Aerzen’s unique combined experience from the worlds of rotary lobe blowers and screw compressors is the foundation upon which the new groundbreaking Delta Hybrid technology has been developed – the first series of Rotary Lobe Compressors.

Delta Hybrid is a synergy of blower and compressor technology.  By combining the technical advantages of both concepts it offers completely new possibilities for generating positive pressure or vacuum in air and neutral gas applications.   A total of 7 patents or patent applications currently make the Delta Hybrid one of the most innovative products in compressor technology. While low pressure applications call for the Roots-principle of isochoric compression, the screw compressor with its internal compression ratio offers greater energy efficiency in higher pressure ranges.   The ideal union of both rotary lobe blower and screw compressor technologies resulted in the Delta Hybrid, a future-oriented innovation that reduces the energy consumption by up to 15% compared to current market leading designs.

Aerzen Screw Compressors

Aerzen offer a range of oil-free and oil-injected screw compressors for air and gas applications.

Package sets can be delivered in acoustic enclosures with intake filter, outlet silencer, pressure relief and non-return valves, drive assembly and monitoring gauges.  All items are specifiable to ensure tailored solutions regard low noise levels or paint specifications.

Delta Screw packages utilise class leading acoustic hoods which optimise efficiency and maintainability. Warm air from the operation is carefully directed away from the intake to prevent short circuiting, thereby maximising the operating range and minimising power consumption. Filters are easily but safely accessed through small lockable removable panels. A single oil-level indicator is used on the front of the machine to allow oil readings to be taken whilst the machine is in operation therefore reducing downtime.
