Hydrogen - Energy of the future

HOFER 1.000 bar dry-running piston compressor for hydrogen

For all process technologies where oil free gas compression is required, dry running piston compressors will be used. These machines operates without any oil lubrication in the gas chambers. The piston motion is performed by crank drive or hydraulic drive. The cylinders are separated by double distance pieces from the crank drive.

With classic dry-running compressors, crank shaft driven, in the past final pressures up to 180 bar could be realized. With the new design, hydraulically driven, final pressures up to 1.000 bar are reachable.

We are considered one of the world-wide leading supplier of high pressure compressors for technical gases, especially for hydrogen. New technologies will obviously increase the demand for hydrogen and ways are searched to store the gas under higher and higher pressures.
For these applications, HOFER Compressor Technologies has decades of international experience and thus, HOFER Compressor Technologies received important purchase orders for the manufacture of high pressure compressors up to 3000 bar for space centres and from 440 to 1000 bar for hydrogen filling stations in the past as well as in the present time.

For the following hydrogen filling stations, ANDREAS HOFER Hochdrucktechnik GmbH supplied one of the main components for filling vehicles with hydrogen.

• Reykjavik, Iceland
• Hamburg, Germany
• Madrid, Spain
• Airport Munich, Germany
• Yokohama Daikoku-Cho, Japan

As one of the market leaders for turnkey plants for leakage-free compression of hydrogen, our business line "high pressure compressors for hydrogen filling stations" is well-prepared for the markets of the future.

Since the foundation in 1920, ANDREAS HOFER Hochdrucktechnik GmbH has won world-wide recognition by innovative technology and high safety standards. Diaphragm- resp. piston compressors as well as valves/fittings, manufactured by us, are required products for the chemical, petrochemical, gas producing industry as well as for and space centres. Their range of application is manifold: from universities and research laboratories up to production plants and hydrogen filling stations.

Via our competent representatives and partners, we are present on all continents. We are readily prepared to answer your questions regarding high pressure technique, from single components up to completely tubed, fully automatic plants as high qualified and competent partners for planning, project handling and after-sale-services all over the world.

High pressure valves/fittings of our production complete our compressors to be turnkey com-pressor plants of high quality and reliability. Beside our standard products, we also supply products in accordance to customer's specifications and operating conditions, which will be individually calculated, designed and manufactured. Carefully quality controls during the complete manufacturing process guarantee, that only faultless and safe products will be despatched.

For more than 80 years, HOFER Compressor Technologies supplies world-wide:

• pressure intensifiers for liquids up to 10000 bar
• piston compressors
• diaphragm compressors
• hydraulically driven, non-lubricated piston compressors

upon request, also completed with valve- and instrument panel.

HOFER Compressor Technologies has many years of experience in the design and manufacture of compressors for the inflator filling for airbags and for isostatic press plants.
