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.

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
