The Delta Hybrid rotary lobe compressors can be used for an extremely wide range of key industrial applications. Economic as a stand-alone and highly efficient in compound machines. The packaged units can be used anywhere, including areas with very high ambient temperatures, or for applications with extreme intake temperatures. Nowadays the Delta Hybrid makes final temperatures of 160 °C to 230 °C possible. A vital prerequisite for high levels of operational safety in all processes.

Freeing Up Potential.
Two profiles. One unit. The latest generation technology from AERZEN brings a new principle to compression, namely the perfect synthesis of positive displacement blower and screw compressor in one packaged unit. The innovative Delta Hybrid rotary lobe compressor uses two different rotor profiles. A 3+3 blower profile tailored for low pressure differentials of up to 800 mbar – and a 3+4 compressor profile designed for higher pressures of up to 1,500 mbar. This enables the Delta Hybrid to close the gap in the existing range of machines. It also offers a broad performance range to enable perfect tailoring to meet the most diverse process requirements – with energy savings of up to 15% compared to standard compressors.

Higher Temperatures. Improved Safety.

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 require the gobilization of all a company’s potential. 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

A total of 7 patents or patent applications currently make the Delta Hybrid one of the most innovative products in compression technology.
