Chlorine and Chlorate Business Group

De Nora’s roots in the chlorine and chlorate industries run deep. From the creation of the earliest commercial diaphragm cells in the early 1900s, to the development of the very first membrane cell and now the most competitive anode coatings available, De Nora provides value from project development to re-coating and replacement parts.

Our interest in improving diaphragm cells continues, providing these plants a competitive edge in producing chlorine and caustic. De Nora provides novel cathode can construction that reduces voltage, diaphragms that eliminate the need for asbestos, cell tops that last a decade or more, and everyday spare parts to keep existing plants running like new.

De Nora has placed its anode coatings and recoatings in more technologies than any other anode coating supplier. We offer recoating techniques for almost any cell type. We have developed cathode coatings suitable for all technologies and have even developed technology to instantly reduce cell voltage without shutting down the rectifier.

As the leader in anode coatings for chlorate cells, De Nora has millions of tons of annual sodium chlorate capacity utilizing our coatings. Recent developments in anode coatings improve the efficiency taking the recoating of anodes from a maintenance item to one that can provide a return on investment.
