On a carrier ship, cooling systems are what keep engines safe, lubricants effective, and voyages on schedule. Push them too hard, or let maintenance slip, and you’re looking at overheating, oil breakdown, or compliance issues that can strand a vessel.

Tranter plate heat exchangers are built for the harsh realities of marine duty. Compact and service-friendly, with the alloys to handle seawater and clean-fuel demands, they help you keep your ships with everything from being efficient and compliant to out of dry dock.

Bulk carriers

Keep engines cool, oil stable, and crews confident

Marine-grade durability

Tranter uses marine-grade stainless and high-alloys proven to hold up on long-haul voyages, cutting premature replacements.

Efficient heat transfer

Our plate patterns deliver high thermal efficiency without excessive pressure drop, keeping engines cool under heavy load while reducing fuel use.

Compact machinery fit

Engine room space is scarce. Tranter frames pack full-duty performance into smaller footprints, easing both newbuilds and retrofits.

Service made simpler

Frames that open easily and clear access points shorten inspections and cleaning, reducing time spent in drydock.

Reliability at sea

Vibration-tested and field-proven, Tranter heat exchangers handle the nonstop duty cycles of your bulk carrier without performance loss.

Global service access

With OEM parts and service centers across the globe, your vessel stays supported wherever it docks.

Bulk carriers

Applications across bulk carriers

Clean fuel engines

Cleaner fuels and efficient heat exchangers are reshaping bulk carriers. Tranter exchangers help you hit IMO targets while keeping engines stable, fuel use down, and performance reliable.

Engine cooling

Marine engines generate enormous heat under load. Our heat exchangers dissipate it efficiently, preventing overheating, engine damage, and costly downtime.

Lubrication system cooling

Without stable cooling, lubricating oil breaks down fast. Our exchangers keep oil temperatures in range and protect your machinery.
