Description & Applications
High-Temperature Zinc Alloy Sacrificial Anode
Specially formulated zinc alloy sacrificial anodes engineered for high-temperature seawater environments. Designed for heat exchangers, coolers, and hot seawater piping systems where standard zinc anodes lose effectiveness.
Key Features
- Optimized alloy composition for elevated temperature environments (up to 70 degrees C+)
- Maintains stable electrochemical potential at high temperatures
- Prevents intergranular corrosion common in standard zinc at elevated temperatures
- DNV type approved for high-temperature applications
- Available in plug, disc, and tubular configurations for heat exchanger internals
Typical Applications
- Shell and tube heat exchangers (seawater side)
- Central cooling water systems
- Hot seawater piping and sea chests
- Diesel engine jacket water coolers
- LNG/LPG vaporizer seawater circuits
