The AERZEN screw blowers of the Delta Hybrid series stand for maximum energy efficiency and minimum life cycle costs. They offer 100% pure process air, high operational reliability and are among the absolute high performers among process air generators. The two new sizes now bring these efficiency and technological advantages to new performance ranges.
The smallest one is the D11S. The package is designed for a maximal volume flow of 780 m³/h. The D16S covers volume flows between 100 m³/h and 1.020 m³/h and adds a further, finely graduated performance size to the portfolio. System manufacturers and operators benefit from greater flexibility in terms of design and more precise adaptation to specific process requirements. Like all Delta Hybrid models, the new models also provide reliable 100% oil- and PFAS-free process air and operate efficiently and economically in an extended turndown of up to 1:5. Energy savings of up to 37% compared to conventional blowers are possible.
Designed for efficiency and reliability
The screw blowers are characterised by an innovative compressor stage with new, highly efficient screw rotor profiles and internal flow optimisation, motors with energy efficiency class IE4 or IE5 and a direct drive. One VFD is already integrated and ensures precise and stepless adjustment of the volume flow to the current demand. Factors contributing to the process reliability include bearings with a theoretical service life of more than 60,000 operating hours, pressure lubrication of the anti-friction bearings, extended oil change intervals of up to 16,000 operating hours and an oil cooler. The machines also set new standards in terms of noise minimisation and are among the quietest on the market in their performance class.
Integrated control and monitoring technology
The integrated AERtronic package control takes over the efficient control and monitoring of the Delta Hybrid. All relevant operating data can be transmitted to the master control system and accessed at any time via browser, tablet or smartphone. This simplifies operation, creates a high level of transparency and supports reliable process control. The result is maximum machine availability, reliability and efficiency.
The Delta Hybrid packages are fully pre-assembled and pre-programmed and are therefore immediately ready for connection and operation. The space-saving side-by-side installation and the excellent volume flow per square metre value result in smaller machine rooms and thus lower building investments. Operation and maintenance are performed exclusively from the front and rear.
Exceptional energy efficiency, extreme compactness, durability and reliability, minimal maintenance costs and quiet operation: with the new sizes D11S and D16S, AERZEN opens up further application possibilities for the Delta Hybrid with direct drive and consistently develops the successful screw blower technology further.
