Screw Compressors Water-flooded 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.

Volume flow:
765.18 to 3.531.6 CFM

Differential pressure (Δp):
43.51 to 130.53 psi

Medium:
Process Gases, Neutral Gases, Aggressive Gases, Hydrogen

Compression:
Oil-free

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

Hydrogen compression at the highest level

The new VRW type oil-free compressor has been specifically designed to compress wet electrolysis hydrogen with unprecedented efficiency and differential pressure.

The VRW follows the dynamic operation and the special requirements of the most modern electrolysers, whether alkaline technology (AEL), proton exchange membrane (PEM), or high temperature (SOEL).

As a pre-compressor for large quantities of H2 from atmospheric electrolysis, the VRW provides downstream compressor types with the inlet pressure that reciprocating compressors in particular require for economical machine designs.

APPLICATIONS:

Green hydrogen
Other gases for oil-free screw compressors: e.g. flare gas
