Product Usage

It can be widely applied to the protection of key equipment such as ships, steel piles wharf, industrial equipment (seawater circulating water pumps, seawater condensers and seawater pipes). The advantage of auxiliary anode whose material is platinum and niobium is size small, large drainage, long service life, stable and reliable, etc. It is also widely used in the sea fresh water environment. The auxiliary anode has a long life span, up to 10 years.


Standard Specification
