Aerzen added smart features, and further improved functionality to its screw blowers Delta Hybrid. The additional blowers provide more energy efficiency, a simplified service and maintenance concept as well as reduced dimensions or smaller footprint. Thanks to a compressor stage with high-efficiency screw profiles, internal flow optimisation, coupled with motors of energy efficiency class IE4, optimised process and cooling air flow as well as a self-tensioning belt drive with an efficiency of over 98 % in conjunction with a pinpoint design, energy savings of up to 30 % are achieved. The control range was extended to 1:5. The bearing enables a service life of 70,000 h and more. The four additional assembly sizes cover volume flows from about 2 to 30 m3/min and driving power from 7.5 to 55 kW.
