Since 1864, AERZEN has engineered high performing machines for the industry.
We have developed from a single machine factory and into a global player, delivering reliable, high performing and energy efficient blowers and screw compressors all over the world. Along the way, we have spearheaded innovation in our field of complex and demanding applications and developed several new technologies not only responding to market needs, but leading it forward.
We are at work for you worldwide. AERZEN is continually developing innovations in blower and compressor technology in over 100 countries worldwide, with more than 50 subsidiaries and approximately 2,500 employees.

Benefit from the extensive know-how that AERZEN has gained from decades of experience in the chemical and petrochemical industry. The use of biogas as an energy source will considerably help to achieve the environmental objectives set nationally and internationally.

We at AERZEN support all these objectives with our more than 50 subsidiaries worldwide. For many years, AERZEN blowers and compressors have been conveying and compressing all types of gas and gas mixtures in plants of the chemical and petrochemical plants. Thereby, energy efficiency, plant safety and reliability are the decisive criteria. Based on this know-how and the experience gained, AERZEN offers products especially developed for the biogas market.
Whether boosting the intake pressure of combined heat and power (CHP) engines and treatment plants for biogas (BGTP) or as an essential part of biogas injection plants (BGIP) for the compression of biomethane to inject into gas grids – AERZEN has the suitable biogas blower or biogas compressor for each application.
Customer-specific solutions can be offered from a wide array of machine sizes and design pressures. All blowers and compressors can be used in hazardous areas Zone 1 and in Zone 2 as defined under ATEX Directive RL 2014/34/EU as well as the Machinery Directive, including the latest safety standard (EN 1012-3) and for Germany the DVGW* regulations.
