Water Electrolysis Hydrogen Generator

MVS is the leading supplier of Water Electrolysis type Hydrogen Generators in India. We have built up this reputation on the foundation of innovative technology, reliable, high quality and very safe equipment. Our equipment caters to requirements across many industries including Thermal power stations, oil processing, chemical processes, float glass furnaces, cylinder filling and for heat treatment requirements.

Water Electrolysis principle

Transformer and Rectifier provide input power as per electrolyzer requirement. In big size hydrogen plants input power to transformer is at 3.3 KV or 6.6 KV or 11 KV. While in sizes up to 25 NM3/hr, 400 Volts LT power supply is used. MVS Bi-Polar electrolyzer is where high purity DM water is broken to H2 and O2. Hydrogen is evolved on cathode side of cells and Oxygen on anodes of cells. This design makes Electrolyzer unit very compact in size. Hydrogen & Oxygen come out separately from cells into Hydrogen separator and Oxygen separator. Then these are cooled in heat exchangers by cooling water and separated from electrolyte by gravity. Then gases are washed by DM water. Finally clean gases come out through de-misters which are located on top of washers.

Hydrogen coming out from H2 washer unit has moisture saturation and around 0.1 to 0.2% Oxygen impurity. If higher purity is desired, then Hydrogen is passed through a Palladium Deoxo catalyst unit which reduces oxygen to 1-ppm level. Then to dry H2 gas, it is passed through a Molecular sieve Dryer unit where moisture is removed to very low Dew point. It has thermal regeneration heaters and automatic switchover Pneumatic valves. This is a No Purge Loss type dryer with no loss of Hydrogen gas.

Compact Modular design

MVS incorporates the use of skids and designing the system in a modular construction. This feature allows easy transportation and easy installation of the system at your site. Our engineer is present at site to oversee installation and also to assist with commissioning and training of your personnel.

Low power consumption
Besides DM Water, power is the single main utility requirement and it is paramount that power consumption be kept to a bare minimum. Hence, in our design power consumption only 4.6 KW per M3 of Hydrogen. At this low power consumption, our design is one of the most efficient generator in the market.
Additionally, since our Hydrogen plants produce gas directly at 15-Bar pressure, for several processes there isn't a requirement of a booster compressor.

Reliable Purity
For many processes where Hydrogen is required, consistent purity is very important. Our generators are designed to deliver high (99.8% with 0.2% Oxygen) purity and very high purity (99.9999% with 1-ppm Oxygen) with the use of an additional purification unit. The consistent purity is maintained in the system by total automated operation and online Oxygen gas analyzers continuously indicate Hydrogen purity.

Ultra-safe operation
Safe operation is incorporated in our systems right at the design stage. Our totally automated machine allows for a safe shutdown of the entire plant in the unlikely case that there is any malfunction or loss of purity.

Safe operating environment
In our design, there is no Air pollution and no fumes. Electrolyte is in closed cells so there are no fumes in the atmosphere. This also prevents blow off gases and there is no spillage of electrolyte.
