Titanium anodes coated with mixed metal oxides (MMO) operate on a different basis than conventional galvanic anodes. They require the use of an external power source (potentiostat), which causes polarization of the anodes and the protected element.
Magnesium galvanic anodes are commonly used for cathodic protection of underground constructions (tanks, pipelines) and for protection of internal surfaces of tanks containing water (eg. water heaters, hot and cold water tanks, condensers, heat exchangers).
Aluminum galvanic anodes are used for cathodic protection in an environment containing chloride ions, because in fresh water and soil aluminum passivates. These anodes are used both for the protection of onshore and offshore constructions. They are used to protect such structures as: steel sheet pilings of wharfs, steel piles of reloading posts in ports, steel anti-flood barriers, etc.
Zinc galvanic anodes are used for cathodic protection both in the environment of salt and fresh water. They are used to protect marine onshore and offshore constructions, vessels (ships, yachts) and underwater pipelines.
EZAL is a family company specializing in the production of anodes for cathodic protection against corrosion. Operating on the market since 1994, we have become one of the European leaders in the production of magnesium anodes. Along with the development of the company we added titanium, aluminum and zinc anodes to our product catalogue.
EZAL’s mission is to provide solutions at the highest level tailored to the individual needs of clients. The high quality of our products and reliability allowed us to enter the most competetive European markets and establish a stable position there. Our ambition is to further develop the company and acquire new customers both at home and abroad.
As part of the quality development of the company we implemented the Quality Management System in accordance with EN ISO 9001:2000 in 2004. In 2017, we renewed this certificate at TÜV NORD CERT GmbH in accordance with EN ISO 9001:2017. We also have a hygienic certificate issued by the National Institute of Hygiene.Learn more
