Aerzen Screw Compressors VR for process gas technology in modular system single- and multi-stage for dry compression of process gases. The Screw Compressor stage is available in 13 sizes with swept volume flows from 600 m³/h to 120.000 m³/h. Differential pressures between 7 and 12 bar are standard at single-stage compression. With multi-stage design discharge pressures of 25 bar and 40 bar max., but also vacuums lower Pe –0,9 bar are achieved.
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 DELTA TWIN series is designed for the oil-free compression of air and neutral gases and is applied especially in industrial compressed-air production. The double-stage units cover motor ratings from 75 to 200 kW and differential pressures up to 10 bar.
The construction of the double-stage VMT-compressors is based on our proven, single-stage compressor series VM.37.
The VMT-series is designed for oil-free conveyance of air and neutral gases and has already been used since 1970 for the industrial generation of compressed air.
For the diverse industrial ranges of compressed air technology the double-stage units were steadily adapted to the changing operation requirements and modified. Experience of more than 200 supplies has developed a compressor unit, which can convert nearly all special applications of compressed-air technology according to the customers' individual requirements. The VMT-compressors cover motor ratings from 90 to 1020 kW and differential pressures up to 10 bar. This series is available in water-cooled as well as air-cooled design.
Aerzen VMX-screw compressors with oil injection are designed for intake flow volumes from 70 up to 3180 m³/h at driving speeds of 50 resp. 60 Hz and an overpressure - single-stage - up to 13 bar (higher pressures or admission pressure operation upon request).
The drive is effected via V-belt resp. toothed belt or directly via a flexible coupling from the driving motor to the male rotor of the air end. Drive by electric motors or internal combustion engines. All stages are suitable for frequency converter-operation (standard).

Aerzen High-Pressure Blowers are equipped with a compression-proof housing (PN 25). Driving shaft and conveying chamber sealed by various sealing combinations. Direction of flow vertical to the bottom. Drive via direct coupling with motor or via flexibly coupled spur gear.
Housing compression-proof for PN 2,5/PN 6. Cylinder with noise reducing chamber on the discharge side, housing with connections for injection- and water flushing, as well as for lubrication - and purge oil supply systems. Conveying chamber by single-acting oil-purged mechanical seals in combination with labyrinth seals sealed on the shaft. Direction of flow horizontal/vertical (depending on size). Drive directly via coupling or flexible spur gear (depending on size).
Patented 3-lobe positive displacement blowers type GM. Blowers with 3-lobe pistons and two patented pre-inlet channels for pulsation reduction. The conveying chamber is sealed by 4 piston ring labyrinth seals. The driving shaft can be sealed gastightly. Vertical direction of flow. Drive via narrow V-belts or directly onto the driving shaft.
Patented 3-lobe blower stage with integrated pulsation reduction, a base support with integrated silencer. Unit extremely compact with hinged motor plate as tensioning device, flexible machinery mountings, suction silencer and more.
Housing flanges with O-ring-seals, vacuum-tight. Lube oil supply is effected by splash lubrication. Shaft seals by combined oil slinger-piston ring labyrinth seals. The driving shaft is sealed by double radial seal rings with grease barrier. Direction of flow vertical from top to bottom or horizontal clockwise (when looking on the driving shaft.) The direction of flow depends on the size.
for volume measurement of gases in various types of construction an sizes. Gas meter sizes from G 40 up to G 4000 for gas volume flow measurement from 0,65 m³/h - 6.500 m³/h. Measuring pressures up to 25 bar. Works tested or officially calibrated as per national and EU-directives.
Rotary piston gas meters have been manufactured since 1930 by Aerzener Maschinenfabrik, one of the largest and oldest manufacturers worldwide. The basis for the design of the gas meter series is from many years of experience and continual dialogue with the end users, as well as using the harmonized EU-standards which will apply to all installations within the European Market. They are manufactured in accordance wiht the Aerzen tradition for quality corresponding to the quality assurance system, certified to DIN ISO 9001 and as per pressure device guideline DGRL 97/23/EG.
