De Nora is the world-wide leader in diaphragm cell technology. In the 1960’s Dimensionally Stable Anodes allowed for lower voltage, longer life and better product quality in all chlor-alkali technologies.

In the 1970’s, expandable anodes were introduced which produced the low voltage of a “diaphragm-gap” cell. Modified asbestos diaphragms were invented which give a much longer life with a stable efficiency. Over the years De Nora continued this tradition of innovation by evaluating each component of a diaphragm cell for better performance.

In this way, De Nora has now developed new alternatives to the standard expandable anodes. Both the Low Voltage Anode and Dublex^® offer real structural saving of 70mV in operation. ESA™ anode, has shown an additional power consumption savings when installed in combination with our non-asbestos Polyramix technology.

De Nora, offer also advanced coating monitoring service. Each recoating local company throughout the world offers low cost and long life recoating options when required and offers a broad range of recoating options remesh, mesh recoating and mini-mesh recoating.
