Ultrapure Water Systems for Hydrogen and Industry

Water Treatment for Hydrogen and Industry

PEM and alkaline electrolyzers require feed water with very low conductivity, since even minor impurities can damage the membrane or catalyst and reduce efficiency. Our reverse osmosis systems with a downstream EDI stage reliably deliver ultrapure water in the MΩ·cm range – the foundation for efficient, long-lasting electrolyzers and a growing range of other industrial applications.

Feed Water for Electrolysis

• Resistivity in the MΩ·cm range, or conductivity typically below 1 µS/cm – to protect the membrane and catalyst from fouling
• Consistent water quality for stable, efficient electrolysis operation
• Scalable systems from pilot plant to industrial-scale electrolyzer

Further Industrial Applications

From solar panel and façade cleaning to humidification, battery production and coating systems, right through to the automotive industry – use the tiles below to reach the detail pages for each specific area.

System Configuration

For electrolyzer feed water treatment, we combine two- to three-stage reverse osmosis with a downstream electrodeionization (EDI) stage, scalable from a pilot plant to several thousand liters per hour for continuous industrial operation. Available as an enclosed stainless steel housing, an open frame, or a cabinet system, including PLC control with conductivity monitoring and optional remote administration for unattended operation.

Service & Support

From commissioning to maintenance contracts at fixed intervals to spare parts service, we support your system throughout its entire lifecycle. Optional remote monitoring detects many issues before they lead to a production outage.
