Key Advantages
- Superior Corrosion Resistance
Outstanding performance in seawater, brackish, and cooling-tower water, resisting pitting and biofouling. - Monometallic Construction
Integral fins eliminate galvanic concerns—no dissimilar-metal corrosion. - High Thermal Conductivity
Copper-nickel alloy provides better heat transfer than stainless steels. - Mechanical Durability
Excellent toughness and fatigue resistance under thermal cycling and vibration. - Low Maintenance
Natural resistance to marine growth yields longer clean-water intervals.
Typical Applications
- Marine Condensers
- Seawater-Cooled Heat Exchangers
- Desalination Plant Coolers
- Offshore Platform Cooling Systems
- Power Plant Condensers
- Chemical and Petrochemical Coolers
