Screw Compressors Water-injected Screw Compressor
Series VRW

Bringing large H2 volume flows to the highest possible intermediate and final pressures with just a few compressor stages, without having to set up huge reciprocating compressor systems for this purpose - precisely here is where the new VRW 536 M oil-free screw compressor from AERZEN comes in.

Technical Data: Suction volume flow up to: 6000 m³/h, pressure range: -900mbar g  to 9 bar g

Volume flow:
765.18 to 3.531.6 CFM

Differential pressure (Δp):
-13.05 to 130.53 psi

Medium:
Process Gases, Neutral Gases, Aggressive Gases

Compression:
Water injected

The advantages of AERZEN VRW Screw Compressor at a glance:

  • 100% oil-free compression
  • Maximum efficiency and increased differential pressure in one stage
  • Minimisation of installation area
  • Reduced investment and operating costs
  • Pre-drying of the wet H2-gas is not required
  • Ideal as a pre-compressor (booster) for the following compressor types
  • Also suitable for other critical gas applications (e.g. flare gas, contaminated gases

TECHNICAL PROPERTIES - THE NEW H2-COMPRESSOR CONCEPT

  • Water injection for cooling the gas and for gap sealing (efficiency increase)
  • Stainless steel design for maximum service life (corrosion resistance)
  • Water-purged mechanical seals at the conveying chamber for 100% oil-free compression
  • Oil-lubricated roller bearings for maximum speed range
  • Speed control for adaptation to fluctuating process conditions
  • Gear-synchronised rotors (no contact with the rotors)
  • Designed for three-year revision cycle (MTBO)
  • Directly coupled or with gear ratio
