Greaterflexibility and efficiency in the high-flow-rate range. With new sizes in the high-flow range, AERZEN is further expanding its successful Delta Hybrid series. The compressor specialist is expanding its portfolio of direct-drive screw blowers with the new D100S and D120S models. 3 Nov 2026 The screw blowers in the Delta Hybrid series from Aerzener Maschinenfabrik are characterized by high energy efficiency, minimal life-cycle costs, 100 percent pure process air, high operational reliability, and a long service life. The introduction of the new sizes now takes efficiency and performance to a new level. New D100S and D120S models open up new performance ranges. With the D100S and D120S models, AERZEN is introducing two high-performance models to the direct-drive Delta Hybrid series. While the D100S unit is designed for a flow rate of up to 6,060 cubic meters per hour, the D120S covers flow rates of up to 7,320 cubic meters per hour and adds another finely graded performance level to the portfolio. This gives plant operators and engineers significantly greater flexibility in system design, as well as the ability to tailor systems more precisely to specific process requirements. Energy savings of up to 37 percent. Like all units in the Delta Hybrid series, the two new sizes provide a reliable supply of process air that is 100 percent oil- and PFAS-free. The units operate consistently with high efficiency and cost-effectiveness across an extended control range of up to 1:5. Compared to conventional blowers, the direct-drive Delta Hybrid series enables energy savings of up to 37 percent. Reliable operational safety with first-class energy efficiency. The screw blowers are designed for maximum load to ensure high process reliability and a long service life. Key factors include bearings with a theoretical service life of more than 60,000 operating hours, pressure lubrication of the rolling bearings, extended oil change intervals of up to 16,000 operating hours, and an oil cooler. These modifications enable continuous operation with minimal maintenance requirements and result in a significant reduction in the total cost of ownership for the operator. Groundbreaking compressor stage. The foundation of thermodynamic efficiency is the innovative compressor stage, which combines newly designed, highly efficient screw rotor profiles with optimized internal flow guidance. A direct drive system, combined with motors in efficiency class IE5 (Ultra Premium), serves as the drive unit. Thanks to the frequency converter integrated at the factory, the delivered airflow can be continuously and precisely adjusted to meet specific process requirements. Furthermore, the units set the standard for noise minimization and are among the quietest systems on the market in their performance segment. Integrated control and monitoring technology. The integrated AERtronic unit control system efficiently regulates and monitors the Delta Hybrid. It ensures that all relevant operating data is transmitted to the higher-level control system and can be accessed at any time via a browser, tablet, or smartphone. This results in simplified operation, high transparency, and reliable process control. This ensures minimized downtime, stable processes, and noticeably greater efficiency. Compact plug-and-play solution. The Delta Hybrid units are designed as a compact plug-and-play solution and are assembled and preconfigured at the factory to be fully ready for connection, making them ready for connection and operation immediately upon delivery. A simple operating and maintenance concept ensures straightforward handling and fast service processes. Future-oriented technology for high efficiency. With the D100S and D120S models, AERZEN is consistently expanding the application possibilities of its direct-drive Delta Hybrid technology into higher performance ranges. Operators benefit from highly efficient and economical process air generation with lower energy consumption, reduced maintenance requirements, and lower long-term life-cycle costs. In this way, AERZEN is opening up further applications for screw blower technology and consistently advancing its development.

AERZEN expands screw blower portfolio with new Delta Hybrid sizes D100S and D120S. 29 October, 2026 With new sizes in the high-volume flow segment, AERZEN is further expanding its Delta Hybrid series. The compressor specialist is expanding its portfolio of direct-drive screw blowers with the new sizes D100S and D120S. The aim is to provide additional flexibility for cost-effective and energy-efficient process air generation in higher performance ranges. The AERZEN screw blowers of the Delta Hybrid series are said to be characterised by high energy efficiency, minimum life cycle costs, 100% pure process air, high operational reliability and a long service life. The introduction of the new sizes is now taking efficiency and performance to a whole new level, according to AERZEN. New D100S and D120S sizes open up new performance ranges With the D100S and D120S models, AERZEN is introducing two high-performance sizes to the direct-drive Delta Hybrid series. Whilst the D100S package is designed for a volume flow of up to 6,060 m^3/h, the D120S covers volume flows of up to 7,320 m^3/h and adds a further, precisely graded performance stage to the portfolio. This gives plant operators and manufacturers increased flexibility in design, as well as the opportunity to customise systems accurately to specific process requirements. Like all packages in the Delta Hybrid series, the two new sizes provide a supply of process air that is 100% oil- and PFAS-free. The packages are designed to operate consistently with high efficiency and cost-effectiveness across an extended turndown of up to 1:5. Compared with conventional blowers, the direct-drive Delta Hybrid series enables energy savings of up to 37%. The screw blowers are rated to withstand maximal loads, enabling a high level of process reliability and a long service life. Key factors include, amongst others, 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. These modifications are intended to enable long-term operation with minimal maintenance requirements and result in a significant reduction in the total cost of ownership for the operator. The basis of the thermodynamic efficiency is the 'innovative' compressor stage, which combines newly designed, highly efficient screw rotor profiles with optimised internal flow guidance. The drive package consists of a direct drive connected with motors in efficiency class IE5 (Ultra Premium). Thanks to the VFD, which is integrated as standard, the delivered volume flow can be adjusted continuously and precisely to the specific process requirements. Furthermore, these packages are designed to set the standard for noise reduction and are said to be among the quietest systems on the market in their performance segment. Integrated control and monitoring technology The integrated AERtronic package control takes over the efficient control and monitoring of the Delta Hybrid. The transmission of all relevant operating data to the master control system, as well as the availability of this data at any time via browser, tablet or smartphone, is said to be guaranteed and to result in simplified operation, a high degree of transparency and reliable process control. This helps to ensure minimal downtime, stable processes and a noticeable increase in efficiency. The Delta Hybrid packages are designed as compact, plug-and-play solutions and are assembled and pre-configured ex works, making them ready for connection and operation immediately upon delivery. A simple operating and maintenance concept is intended to ensure straightforward handling and swift service procedures.
