A multi-stage development of the diaphragm compressor.The Howden "H" series is available in horizontal or vertical configurations of up to five compression stages, offering pressures increases of to 450 bar while providing inter-stage cooling and purging of condensates. These units are suitable for virtually all dry gases including helium, hydrogen and nitrogen. Water cooled heads,HIDS Head Integrated Detection System on each compression head,Purged packing design option (optional),3 or 4 compression stage designs (optional)Vertical and horizontal constructions. Reciprocating technology facilitates accessible maintenance for site operators.Conservative rotation speed reduces fatigue.Compact skid mounted designed to project & site specifications for an easy integration to process.Purged packing design option is available to collect leakage from piston compression stages.Dry compression ensures clean gas and machines are low rotation speed. He high pressure compression solutions and all dry gases N2, H2 process.He gas compression for bottling and Aerospace.Dry gases compression for bottling.Dry HC, H2, N2 high pressure for process feeding, blanketing and gas network.
