Voltage monitoring system HydraSafe

for process controlfor predictive maintenancemodular

Short description
Cell voltage monitoring of electrolyzers provides operators with valuable insight into the efficiency, stability and safety of the hydrogen electrolysis process. It enables detection of membrane degradation and defects such as pinholes, cell leaks, insufficient electrolyte supply and electrode coating loss. Operators can adjust process parameters or schedule maintenance based on the measurements. HydraSafe is modular, flexible and engineered for rapid installation, combining field experience with requirements of a scaling industry.
