COMPONENT OF YOUR PROCESS EFFICIENCY: AERZEN PROCESS GAS COMPRESSORS 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.   THE UNIT DESIGN CAN BE EFFECTED ACC. TO THE FOLLOWING GUIDELINES: DIN / EURO standards NACE AD-regulations TEMA - standard ASME VIII Div. 1, incl. U-stamp API-guidelines ATEX TYPE OF TECHNOLOGY SCREW COMPRESSORS VOLUME FLOW 550 to  120,000 m3/h MEDIUM AIR , NEUTRAL GASES , PROCESS GASES , AGGRESSIVE GASES COMPRESSION OIL-FREE NEGATIVE PRESSURE MAX. -900 mbar POSITIVE PRESSURE MAX. 52,000 mbar   STANDARD COMPRESSORS OR INDIVIDUALLY DESIGNED PACKAGED UNIT: AERZEN PROCESS GAS SCREW COMPRESSOR REPRESENTS BOTH.   The screw compressors are individually designed to fulfil widely differing requirements.
