The hydraulic-driven gas boosters from the vertical VOB-H2 Series enable safe hydrogen compression with a wide range of discharge pressures and flow rates. The hydraulic-driven compressor is used in gas processing and hydrogen gas storage applications, hydrogen refueling stations, pressure testing and in more applications. The separation between the gas chamber and the hydraulic section have been especially engineered to cater for safe use with hydrogen gas and avoid oil contamination of the gas. The vertical lay-out of the booster causing less wear, less friction and resulting in energy efficient compression. the gas booster can be used safely for the compression of other industrial gases such as CNG, nitrogen, and more. The careful selection of materials warrants a longer lifetime as hydrogen embrittlement is reduced. To enhance the versatility of the VOB-H2 hydraulic-driven gas boosters, the gas boosters are available as double-acting, and dual-stage versions.

Benefits & Features

• Great application versatility due to wide supply pressure range from 2 to 1100 bar and discharge pressure range from 10 to 1,100 bar • Safe hydrogen gas compression due to separation of the gas chamber from the hydraulic section with vertical lay- out to avoid oil contamination • Universal use and multiple configuration possibilities based on a modular and interchangeable design of the gas section and 5 compression ratios • Vertical positioning of boosters prevents bending, causing less wear, less friction and resulting in ab even more energy efficient compression.

• Effective prevention of hydrogen embrittlement due to specific material choice • Long life time by using specific hydrogen engineered polymer compounds based low-friction PTFE resins for optimum piston sealing • Reduced wear on parts due to self-lubricating piston reducing friction during operation • Reduced maintenance time by design allowing replacement of the high pressure seals and check valve within 30 minutes • Engineered according the European standards CE and ATEX standards

Application Areas

• Hydrogen refueling stations • Gas pressure testing with hydrogen, nitrogen, CNG, and other gases • Gas processing of hydrogen

• Charging of accumulators with hydrogen and other gases • Storage of hydrogen and other gases
