-   Press Releases NEW: AERZEN Delta Hybrid with new top marks

Maximum volume flow with the smallest footprint and best energy efficiency

For 160 years, AERZEN has been developing high-performance machines for industry and continuously driving the development of compressor technology with innovations. The latest coup: the new sizes of the successful Delta Hybrid series. The innovative screw blowers with direct drive using gear wheels, optional IE5 synchronous permanent magnet motor and integrated VFD are digitally ready and impress with maximum energy efficiency, the smallest footprint, maximum user-friendliness and absolute process reliability. A compact plug & play solution for the highest demands.

AERZEN rotary lobe compressors, also known as screw blowers, stand for the highest level of innovation, uncompromising quality, exceptional energy efficiency and unconditional reliability and are used worldwide in a wide variety of applications. With the innovative further development of the successful series AERZEN is now taking the next step. The future-oriented design sets new scales regarding energy efficiency, durability, machine footprint, digitalisation, low noise levels and maintenance requirements, making the new sizes an absolute high performer in process air generation.

Efficiency in a new dimension
The new Delta Hybrids provide reliable, 100 % oil-free process air and operate highly efficiently and economically in an extended turndown ratio of up to 1:5. Energy savings of up to 37 % compared to conventional blowers are possible. This is unique on the market and supports applications in a targeted manner to greater resource and cost efficiency. This major leap in efficiency is achieved thanks to a sophisticated technology concept that is precisely tailored to customer requirements. The most important components include an innovative compressor stage with new, highly efficient screw rotor profiles and internal flow optimisation, a direct drive for the use of motors with energy efficiency class IE4 or IE5 including an integrated VFD and a smart oil system. The synchronous reluctance permanent magnet motors also offer high efficiency in partial load operation.

User-friendly plug & play solution with the smallest footprint
The robust design ensures unrivalled reliability. Even under the most difficult environmental conditions, the Delta Hybrids ensure safe operation. The new screw blowers are designed for intake temperatures from -40 °C to +50 °C and therefore cover an extended field of application. An optional acoustic hood for outdoor installation allows the machines to be used even under direct weather conditions. Delta Hybrid packages are ready for immediate use on delivery and take up a minimum of floor space. The space-saving side-by-side installation
