Process gas compressors are a key technology in many industrial processes which place high requirements on availability, efficiency and process stability. As an experienced industry partner, AERZEN has a thorough understanding of the challenges specific to each application. Since January 2026, the company has been consolidating its process gas expertise within Aerzen Process Gas GmbH, a wholly-owned subsidiary of AERZEN. The integration of Emmerthaler Apparatebau GmbH and GPE Turbo expands the range of services and increases the technological and systems expertise. Aerzen Process Gas GmbH offers expertise from a single source, whether it’s blowers, compressors or turbochargers, modifications and accessories, the manufacture of reservoirs, piping and silencers or packages: This combined expertise and high level of innovation reduces interface complexity, enables the end-to-end implementation of complex plant solutions and thus shortens project lead times.
Portfolio for the process gas industry
AERZEN blowers, compressors and turbochargers bring together know-how and experience gained from more than 160 years of technological expertise. They stand for reliable product quality, efficiency and process reliability, as well as reduced capital and operating costs. The product range of Aerzen Process Gas GmbH comprises rotary piston, screw and turbine technology for pressures of up to 300 bar and volume flows of up to 350,000 m³/h. The positive displacement blowers achieve a differential pressure of 2 bar at a maximal working pressure of 25 bar a, as well as volume flows of up to 104,000 m³/h. The screw compressors cover pressures up to 25 bar and volume flows up to 75,000 m³/h. The turbo compressors are suitable for pressures of up to 300 bar and volume flows of up to 350,000 m³/h. They are available in a wide variety of types of construction, sizes and special designs for almost all gases, and are used in both onshore and offshore applications. All relevant international rules, building regulations or specifications of various industries or acceptance organisations are complied with.
AERZEN process gas machines are rated for continuous operation and will run for decades with minimal maintenance costs. They are at home in all key industrial applications and ensure reliability and cost-effective production processes. Typical applications include compression, conveying, recirculation and recovery of process gases and gaseous mixtures, as well as pressure boosting, for example in the chemical and petrochemical industries, in refineries, coking plants and steelworks, in power generation, industrial gas production, the refrigeration industry, helium cooling and liquefaction, and in oil and gas transport.
