Top mounted marine engine box coolers are specially designed for medium-sized cargo ships. Installed on the top of sea chest, it utilizes sea water to cool main engine circulating water and lube oil. Featuring compact layout, no extra sea water pump required, it saves engine room space and runs reliably during navigation and berthing.
This top-mounted box cooler adopts U-tube heat exchange structure, installed atop the ship's sea chest. It relies on sailing water flow and natural convection to realize heat exchange, serving the cooling system of main engines on medium cargo ships. With excellent seawater corrosion resistance and anti-fouling performance, it has fewer moving parts, low failure rate and simple daily maintenance.
