Aerzen - Model Series VRW - Water-flooded Screw Compressor -

Bringing large H2 volume flows to 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. Compression is based on the principle of oil-flooded screw compressors - with a small but subtle difference: the oil was replaced by water. The water serves both for cooling the gas and for gap sealing and enables compression to higher differential pressures with high efficiency. This stage can replace a two-stage system with classic dry screw compressors and is even more energy efficient. For the customer, this results in significant advantages in terms of footprint as well as investment and operating costs.
