LX-Series™ Two-Stage Hydrogen Gas Compressor

Two-stage compressors are used when the compression ratio exceeds 8:1. The principle of operation is very similar to the single-stage units. The main difference is that the diameter of the second stage gas cylinder is smaller than the first stage gas cylinder. The interstage cooling that occurs between stages allows higher overall compression ratios. The compression ratio for a two-stage machine is limited to approximately 64:1.
