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.

The unit is ideally suited for dry compression of all gases, which occur in chemical and petrochemical industries. Within the compression chambers there is no metallic contact among both rotors as well as to the casing. Thanks to synchronising gears the rotors run without contact to each other. Therefore, the conveying chambers remain unlubricated and the conveyed medium will not be contaminated.

The maximum (1350 mm) and the minimum rotor length (155 mm) give an impression of the entire breadth of the offer. For the adjustment to the different process gases, rotors made of steel or special steel and casing of nodular cast iron, steel- or special steel casting can be applied.

  • DIN / EURO standards
