Marine heat exchangers
Common industries: HVAC Industry, Data Centers Industry, Healthcare Industry
Overview
Keel coolers and box coolers exchange engine heat directly to the surrounding seawater, exposing the tube bank to chloride attack, biofouling growth, and cavitation at the ship-hull interface where wake turbulence is highest. Belzona 1321 (Ceramic S-Metal) coats the cooler tubes and end covers with ceramic-filled corrosion protection at full seawater immersion; Belzona 2141 (ACR-Fluid Elastomer) lines the upstream zones where cavitation damage is the dominant failure mode. The system installs during the annual dry-dock window with no replacement of the cooler bundle.

About Heat Exchangers
Galvanic corrosion at dissimilar-metal joints, erosion at tube inlets, and chemical attack on water-side internals are the dominant failure modes on industrial heat exchangers. Belzona supplies a graded family of coatings and composites to rebuild lost wall thickness and electrically isolate the tube bundle from the water-box wall.
