Rotary lobe compressors Delta Hybrid

Rotary lobe compressors

The Delta Hybrid Rotary Lobe Compressor derives from the fusion between the screw compressor technologies and the rotary lobe blowers. This combination results in a machine that combines the technical advantages of the two concepts, offering new possibilities for generating vacuum or positive pressure.

Roughly 90% of a compressor’s life cycle costs are consumed by energy. While this presents a huge challenge, AERZEN’s Delta Hybrid is providing companies with ideal solutions that offer up to 15% energy savings thanks to its compressor’s energy efficiency, even in high-pressure ranges.

Get the Delta Hybrid Rotary Lobe Compressor and enjoy benefits such as:

  • Reduced life-cycle costs
  • Extraordinary energy efficiency
  • High reliability levels
  • Reduced maintenance needs
  • Increased range of pressures and applications
  • 100% pure process air, free of absorption materials and oil

The benefits of Delta Hybrid at a glance:

Easy handling, minimal maintenance: these are characteristics that have a direct impact on efficiency and your bottom line. A good reason why AERZEN kept them in mind when it developed the Delta Hybrid generation. The results will be convincing even for hard-nosed accountants – and will be a joy to use in day-to-day operation.

Extraordinary energy efficiency

  • Up to 15% energy savings compared with conventional compressors
  • Control range between 25% and 100%
  • Reduced pressure and airflow losses
  • Use of Premium Efficiency / IE3-Motoren
  • Belt-driven for precise volume stream determination

Extended pressure ranges and opportunities

  • Application range to pressures of up to 1,500 mbar
  • Application range to  negative pressures of up to -700 mbar
  • Outlet temperatures ranging from 160°C to 230°C

No absorption material to interrupt operation

  • Reduction of noise in the discharge muffler by retouring air flow instead of absorption material
  • The downstream process system won’t be contaminated (important eg. within food industry)
  • Certified as spark extinguisher for ATEX applications

Reliability and durability

  • Patented bearing, nominal lifespan of more than 60,000 hours (at 1.000 mbar pressure difference)
  • Patented driving- and conveying chamber sealings
  • 100% oil-free per Class 0 (certified per ISO 8573-1)

Extending the functional range for a wide variety of applications.

Delta Hybrid operates in an extremely wide range of key industrial applications in wastewater and pneumatic conveying. The machines are designed for the oil-free conveyance of air for positive pressure applications with the nominal widths from DN 100 to DN 300.

Hotter temperatures. More safety.
Delta Hybrid screw blowers can be used globally. Also in zones where extreme ambient temperatures of -40°C to +50°C prevail. With Delta Hybrid, discharge temperatures of up to 230 °C are possible today. The prerequisite for operational reliability in all processes.
