Square Condenser Aluminum Anode

Description

The condenser aluminum anode is an economical and efficient choice for protecting against corrosion in saline water environments with low electrical resistivity. Compared to magnesium and zinc anodes in saltwater, it offers higher current efficiency despite its lighter weight.

This anode features a galvanized steel pipe core for easy mounting on steel studs. It is widely employed in cathodic protection for tank interiors, condenser water boxes, heat exchanger shells, chillers, and cooling water system tubes or tube sheets.

Quality Substrate Material
Manufactured from low-iron, high-purity alloys, our condenser aluminum anode conforms to ISO, NACE, and DNV standards.
