De Nora provides products and services based on electrochemical technology through two main product lines:
De Nora can service a wide range of customer technical needs for all the electrochemical processes with:
Anodes and cathodes for Chlor Alkali Industry (Amalgam/Diaphragm/IEM cells)
Anodes, Cathodes and GDE for Hydrochloric Acid Electrolysis
Anodes for Chlorate and Perchlorate production
Anodes for Surface Finishing
Anodes for Electronics
Anodes for Electrowinning and metal recovery
Anodes for Pool chlorination
Anodes for Industrial Electrochlorination
Anodes for Cathodic Protection systems
Anodes for Water Treatment
Range of DSA® Anodes applications
DSA® Anodes are titanium anodes coated with a proprietary and patented Mixed Metal Oxide (MMO) solution of Precious Metals such Iridium, Ruthenium, Platinum, Rhodium, Tantalum.
Thanks to their specific characteristics and the changes in the coating formulation and in the coating techniques, the use of DSA® Anodes supplied by De Nora can range from the long established application in the Chlor-Alkali industry to the most recent utilization in a wide range of other uses in the Electro-galvanic industry, Copper foil, Printed Wiring Board, various water treatment processes, and ultimately Cathodic Protection against corrosion for the iron structures in soil, in concrete and sea water. etc.
The direct sea water Seaclor® electrochlorination systems are to-day marketed by a sister company, Severn Trent De Nora, to which De Nora supplies the electrode packs on an exclusive basis.
Energy saving and environment protection
De Nora ’s main objective has always been the improvement of its proprietary coatings to achieve the longest possible life in operation and the reduction on power consumption of the anodes. Today De Nora offers (through its Spare Parts & Service Division) Zero Mercury Emission packages for the improvement of the cathodic area of the amalgam cells reducing the loss of Mercury to well below the limits imposed by authorities.
In the field of Surface Finishing De Nora offers GreenChrome™ a specifically customized product for the decorative chrome plating processes that obtain excellent results allowing the conversion of carcinogen Cr6+ baths to environmentally and non poisonous Cr3+ baths.
Services
Uhde GmbH and Uhdenora S.p.A. manufacture IEM and HCl electrolysers for their licensees in De Nora Deutschland one of the factories of De Nora that has been equipped, since 1998, with Laser welding machines customized for the assembly of the latest generation of anodic and cathodic “single element” with proprietary DSA® Anodes, activated cathodes and ELAT™, in cases of HCl specifically developed for these cells.
All the electrochlorination systems marketed by Severn Trent De Nora are equipped with electrode packs coated and assembled either in Italy, in De Nora Elettrodi (Suzhou)and in De Nora Tech.
Financial – Leasing opportunities
In the seventies, when the metallic anodes coated with Mixed Metal Oxides were initially commercialized, Permelec , now De Nora, started manufacturing the anodic structures at its own cost offering them to its Customers on a Lease basis granting a continuous electrodes efficiency by a scheduled maintenance and re-coating service under its full responsibility and expense.
Today, De Nora owns more than 80,000 anodic structures installed in amalgam plants and almost 200,000 anodes installed in diaphragm technology plants: the world’s largest DSA® Anodes structures inventory.
De Nora is always available to study and prepare a financing scheme based on a lease contract, in particular when working with partners like Uhde and Uhdenora, also for the IEM technology even if for such a technology the anodes and cathodes are an integral part of the Electrolyzer structures.
