Heat Exchangers

DuraCooler SuprStak

A double-stacked DuraCooler keel cooler with TurboTunnel design, engineered to deliver greatly enhanced heat transfer in half the hull space.

Angled TurboTunnel headers jet seawater between the upper and lower tube decks.

Round turbulizer spacers and flow-diverter scoops increase turbulence and convection.

Design validated with CFD modelling and full-scale water tunnel testing.

Design

Completely redesigned DuraCooler that stacks two tube assemblies with a tunnel between them to promote turbulent seawater flow.

Main and auxiliary engine cooling where hull space is limited.

Developed with computational fluid dynamics and validated in a full-scale water tunnel.
