DuraCooler SuprStak (Patent pending) with TurboTunnel Design

DuraCooler SuprStak Revolutionary keel cooler design more than doubles heat transfer in half the hull space. The best answer for the marine industry's ever increasing cooling requirements. It is a double-stacked, completely redesigned DuraCooler engineered to "jet" turbulent seawater in a tunnel-like configuration between its upper and lower tube assemblies.


DuraCooler Keel Cooler

DuraCooler Latest updated version of the one-piece, hull-mounted DuraCooler greatly improves cooling efficiency over a square head design. Engineered diverter "scoops" have been added to the original design along the bottom width of the tube assembly that "flush" stagnant areas between the tubes with seawater, greatly enhancing heat transfer.


Demountable Keel Cooler

Demountable Keel Cooler/Spiral Tube Our 90/10 cupronickel spiral tubing is resistant to salt water corrosion and sea growth, and gives superior heat transfer. Its demountable, modular design is available in 4, 6, 8, 12, and 24 tube units that can be combined to cool multiple circuits.


Duramax BoxCooler

BoxCooler Gives you in-hull protection and large cooling capacity. Operates in a sea chest within your vessel protected against underwater hazards. Cooler tubes are coated with a heat-cured synthetic coating that protects against galvanic corrosion.
