Aerzener Maschinenfabrik GmbH
Aerzener Maschinenfabrik GmbH is a global application specialist for the conveyance and compression of air and gases. The company manufactures high performance rotary lobe blowers, screw compressors and rotary lobe compressors.
With its machines and systems, AERZEN is the market leader for compressed air applications. Blowers and compressors are used for the pneumatic conveyance of bulk solids, pumping of neutral or aggressive gases in vacuum technology , or safe generation of compressed air.
Technology leader in sewage treatment
The main field of application for AERZEN compressors is water and wastewater treatment.
The machines generate compressed air for the oxygen supply in the ventilation tanks of the sewage treatment plants. The oxygen contributes to a biological purification of the wastewater. This process requires a considerable amount of energy. With its innovative technologies, the company sets standards for more sustainable, energy-efficient, and environmentally friendly solutions for sewage treatment plants. AERZEN is a member of the Working Group Water 4.0 and offers customers special audits (AERaudit) for energy and resource-conserving wastewater recycling.
A company with a proud tradition
The company can look back on a 150-year success story: It was founded in 1864 by the manufacturer Wilhelm Meyer in Aerzen, Lower Saxony, Germany, and has continued to evolve ever since. An early milestone was the development of the first roots-type rotary lobe machine, developed in 1868. AERZEN has been operating as a limited liability company since 1907, and since 1909 has been able to patent many important innovations. To date, AERZEN has continued to develop new, more efficient compressed air technologies, and continues this tradition with innovative solutions for wastewater technology: such as Performance3, new technologies for heat recovery through heat exchangers, or the development of low-maintenance, oil and absorption-free screw compressors. The company employs approximately 2,000 people at more than 48 locations worldwide.
The Aerzener Maschinenfabrik is certified several times. It has the company certificates DIN ISO 9001, ISO 14001, ISO 50001 and BS OHSAS 18001: 2007 as well as various application and traceability certificates.
