This unique expertise from the worlds of positive displacement blowers and screw compressors is the foundation upon which the new groundbreaking and future-oriented Delta Hybrid technology has been developed – the first series of Rotary Lobe Compressors! Delta Hybrid is a synergy of blower and compressor technology, and offers completely new possibilities in overpressure and negative pressure generation of air and neutral gases by combining the technical advantages of both concepts. The ideal union of both rotary lobe blower and screw compressor technologies resulted in the future-oriented Delta Hybrid innovation that reduces the energy consumption by up to 15% compared to usual compressors. Thanks to this targeted expansion of the product range, the negative pressure range has been extended as well. As in the negative pressure range, conventional positive displacement blowers based on their design principle are limited to a maximum differential pressure of -500 mbar, expensive vacuum pumps used to be applied for lower pressure ranges. The application range of the Delta Hybrid packaged units had been extended by the new type of construction E to a pressure range of up to -700 mbar. This new pressure range offers new opportunities in the range of suction conveyance and is applicable, e.g. for applications in the foodstuff industry, plastic granulate pneumatics or chemistry. Delta Hybrid E, therefore, fills the gap in AERZEN machinery portfolio. The advantages for system manufacture and user are obvious: reduced investment costs, higher energy efficiency and more flexibility in the suction conveyance.
