Spherical Aluminum Heat Treater Anode
Spherical aluminum anode for heat treaters. Ideal for high-temp, low-chloride environments. Easy replacement and optimal performance.
Description
The aluminum anode sphere is a small, replaceable sacrificial anode used in heat treaters, pressure vessels, and similar production equipment. It functions best in environments with elevated temperatures and low chloride saltwater or freshwater conditions.
Quality Substrate Material
Manufactured from a high-voltage and high-potential alloy, our aluminum ball anode meets the requirements set by ISO, NACE, and DNV standards.
