The B10 CuNi 90/10 seawater engine intercooler is designed for marine engines, coastal power plants, offshore platforms, and other seawater-cooled engine applications. Seawater flows inside the B10 copper-nickel tubes while charge air passes across the external finned surface, providing efficient heat transfer with improved resistance to seawater-side corrosion.
The complete cooling assembly can be customized with tinned copper fins, nickel-plated copper-iron composite tube sheets, and a hot-dip galvanized steel frame, providing a durable material system for long-term coastal and marine service.
Features
B10 CuNi 90/10 Seawater Tubes: Offers improved resistance to seawater corrosion and localized attack compared with standard copper tubes.
Efficient Charge-Air Cooling: Tinned copper fins provide good heat-transfer performance while adding surface protection for coastal environments.
Marine-Grade Construction: Nickel-plated composite tube sheets and a hot-dip galvanized frame provide additional corrosion protection for offshore, marine, and coastal applications.

How We Produce
The manufacturing of every SINRUI radiator involves meticulous process oversight in our advanced workshop. It begins with accurate copper tube formation and fin attachment, followed by solid-frame welding, all performed according to international norms to assure resilience and efficiency.
Following ISO 9001 protocols, our plant then puts each unit through thorough leak, pressure, and thermal checks. This process promises customers uniform quality, a prolonged lifespan, and reliable heat dissipation.
