Aerzen USA was founded in the United States in 1983, and is a wholly owned division of the German manufacturer, Aerzener Maschinenfabrik GmbH. Founded in 1864, Aerzener Maschinenfabrik is a recognized world leader in the production of rotary positive displacement machines since 1868.


The differences in compressor technologies can be found right where the demanding applications are. Where often highly critical processes gases and coolants are compressed. In the chemical, petrochemical, energy, food, or pharmaceutical industries. The demands on plant design, engineering, documentation and worldwide service in those industries are often just as high as the safety and environmental guidelines to be followed.

Aerzen process gas compressors are installed as single or multiple stage units in chemical, petrochemical, raw material and energy producing plants and in many other production centres of the processing industry all over the world.

Aerzen Screw Compressors VMY are oil injected and the ideal choice for a whole range of process gas and industrial applications, where reliability and low operating costs are prime requirements. The oil injection makes the compressor insensitive to fluctuating volumes, temperatures and pressures. Further fields of application: compression of biomethane or biogas on request.

  • Process Gas Solutions Video

    AERZEN offers the process gas and refrigeration industries an incredibly broad spectrum of positive displacement compression technology, perhaps the broadest of any manufacturer. Specializing in rotary lobe blowers and screw compressors, onshore and off-shore, and in every single key industrial application.


  • The Essentials To Selecting Optimal Compressor Technology

    From venting off-gasses to moving gas from one point to another, compressors facilitate a variety of critical tasks within the complex maze of chemical production plants. While typically more expensive than blowers, compressors operate more effectively in environments that are subject to higher pressures.

  • Blower Technology Not A One-Size-Fits-All Proposition

    Blowers play a critical role in a variety of processes at chemical production plants. While lower in pressure capability than compressors, blowers are typically less expensive and operate more effectively in environments that are subject to lower pressures.

  • Aerzen Steam Blower Case Study

    ZLD (zero liquid discharge) is a wastewater distillation process that helps reduce waste brine discharge to the environment and recover the majority of the wastewater as clear reusable water. In addition, it can turn the brine to a solid waste and in some cases even a useful product that can be profitably sold.

  • Aerzen Flare Gas Case Study

    Flaring gas is the process of burning off unwanted gas from hydrocarbon processing plants, refineries, and gas wells. It is recognized as a major environmental problem by the EPA and the IPCC. Approximately 150 billion m3 of waste gas is flared globally, which contributes to contaminating the environment by 400 Mt CO2 per year. Flare gas is identified as any gases that are burned off into the atmosphere. By 2018, in the USA, the EPA has mandated that all 142 refineries nationwide will need to comply with reducing toxic air pollutants to 5,200 tons per year and 50,000 tons per year of volatile organic compounds. This will result in a reduction in greenhouse gases equivalent to more than 660,000 tons per year of carbon dioxide.

  • Aerzen Air Separation Case Study

    Aerzen USA’s customer (plant operator) has a contract to operate an air separation plant supplying oxygen to a glass furnace at a lighting products company. The glass furnace’s oxygen-enhanced combustion technology improves furnace performance by displacing combustion air with oxygen. By reducing or eliminating the introduction of inert nitrogen into the furnace, the oxygen enhanced combustion technology increases production, decreases fuel consumption, and reduce emissions, while maintaining or even increasing product quality.
