ECOVAR® – Standard on-site solutionsHYDROSS™ Hydrogen generation plants based on the electrolyzer process ECOVAR® supply systems encompass the supply of industrial gases with on-site plants. The HYDROSS™ product line is part of the ECOVAR® portfolio. The plants are built around proven, state-of-the-art components providing maximum cost efficiency and reliability. An integrated compressed gas supply system ensures a continuous supply around the clock. HYDROSS™ plants are the right solution if a long-term, cost-effective hydrogen supply is required. HYDROSS™ are standard plants based on the electrolyzer process. These plants are designed for those who require hydrogen volumes from 5 m3/h up to 250 m3/h at purities up to 99.9 % without additional purification and up to 99.999% or even higher with purification and up to 25 bar pressure without additonal compression. With additional compression higher pressures may be obtained. Larger units can also be supplied if required. The compact dimensions and light weight simplify installation. The skid mounted unit can be installed either in an existing room or in a container placed outside. Each unit contains an electrical unit and an electrolyzer unit. For purities above 99.9 % also a purification unit is required.

High purity oxygen can also be produced if required (50 % of the hydrogen flow). The high degree of modularization and standardization of the HYDROSS™ plants.03-1. Applications ECOVAR® systems based on HYDROSS™ plants are typically used for the following applications in the industries described below: Metallurgical & Metals working industry Heat Treatment Fuel and laser cutting Glass industry Tin bath inerting Cutting & polishing Oils & fats industry Hydrogenation Electronic & Semiconductor industry Inerting Reactant Chemical & Pharmaceutical industry Inerting Reactant Environment Fuel for transportation Subject to alteration. The oxygen is reacted with hydrogen over a catalyst and the water is removed in an adsorption drier.com H2 + O2 Cathode Anode Overall 4 H 2O + 4 e – 4 OH – 4 H 2O ➔ ➔ ➔ 2 H2 + 4 OH– O2 + 2 H2O + 4 e– 4 H2 + 2 O2 H 2 O + KOH Process diagram for the electrolyzer process Process and technology HYDROSS™ uses the electrolyzer technology that decomposes water into hydrogen and oxygen by means of an electrical current. Standard purity from the electrolyzer is 99. The electrolyzer consists of electrolysis cells. Through the nearest Linde operational center the total ECOVAR™ system is kept under 24 hour surveillance. All that is required is water and power and you get hydrogen. reassures best possible reliability and warranties uninterrupted supply of product. each containing two electrodes and an ion-exchange type membrane.linde-gas. The produced hydrogen and oxygen are prevented from recombining by the membrane. In case higher purity is required a deoxo-drier purifier is required. The HYDROSS™ plants are equipped with PLC and modem for remote monitoring and control. 43490662 05.9 %. The HYDROSS™ plants are based on many years of experience and are equipped with state-of-the-art technology and built of components of highest quality.1 ku . oxygen is being produced at the anode and hydrogen at the cathode. Printed on chlorine-free bleached paper. HYDROSS™ units can change output between 25 and 100 % within seconds.0 Fax: +49 89 7446 -1230 www.
