Aluminum Anode Sled

Aluminum Anode Transport Platform: A robust solution for stable performance in electrolytic environments, offering precise voltage control and high efficiency.


This aluminum pyramid anode is specifically engineered for the replacement of worn-out anodes on established offshore installations. Its installation is swift and straightforward, requiring a simple lowering onto the seabed. This efficient method of attachment not only saves time but also significantly reduces costs compared to alternatives like underwater welding. As a result, our anode sled proves to be the perfect solution for retrofitting anodes on subsea equipment and platforms.

Fabricated from high-purity alloys with minimal iron content, our anode sled meets the stringent standards set by ISO, NACE, and DNV.
