Rotary lobe compressors

Used in a wide range of key industrial applications

Efficiency as principle in compressor technology.

About 90% of a compressor’s life cycle costs go to energy use*. A huge challenge, especially where ecological demands and global competition requires the globalisation of potential of the whole company. AERZEN is meeting this challenge with energy savings of up to 15%. Which means the investment will pay for itself after only two years, depending on the volume streams and pressures involved. That’s the Delta Hybrid.

Delta Hybrid, the groundbreaking Rotary Lobe Compressor, is the result of a synergy between the rotary lobe blower and the screw compressor technologies and offers completely new possibilities for generating positive pressure or vacuum by combining the technical advantages of both concepts.

While low pressure applications call for the Roots-Principle of isochoric compression, the screw compressor, with its internal compression, becomes the preferred choice for its energy efficiency in higher pressure ranges. The package concept is based on the well known and successful Aerzen Delta design (Delta Blower and Delta Screw) and has been systematically upgraded.

The benefits of Delta Hybrid at a glance:

  • Extraordinary energy efficiency (energy savings of up to 15%)
  • Reduced life-cycle costs
  • Greatly increased range of applications and pressures (control range of 25% to 100%)
  • High levels of reliability, long service life
  • Reduced maintenance needs
  • Processed air 100% free of oil and absorption materials

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

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 contaminatedt (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)
