Electric Motor & Hybrid Engine Cooling Systems

Electric and Hybrid boats use high amperage batteries which give off large amounts of heat when in use or re-charging. This heat must be carefully controlled to provide optimum performance and to prevent dangerous Lithium fires. 

Titanium Shell & Tube heat exchangers are the best way to reject electric motor and battery heat to the ocean.  They are light weight (50% lighter) and can be configured to fit vessel’s available space. While Plate and Frame exchangers require regular cleaning and new gaskets; the Titanium Marine exchangers need only a simple flushing.

Designed for high tube side velocities, the Shell & Tube units create a ‘self scouring’ flow inside the tubes which keeps marine growth to a minimum.  If excess electrical heat loads are experienced, the units can be ‘over driven’ with extra water flow for a significant increase in heat transfer, without concern for the safety of the tubes or header boxes.

Titanium Marine specializes in manufacturing both marine electric boat motor & engine cooling systems, as well as hybrid battery engine cooling systems.


Your diesel main engines and generators need efficient cooling for long service life. Rejecting engine heat to the ocean requires thousands of gallons per hour of sea water flowing through the jacket water and turbo intercoolers. Traditional copper-nickel engine coolers will fail over time and can pump raw sea water INTO the engines and auxiliaries.

This type of failure can cost tens of thousands of dollars and months out of service. With titanium jacket water and turbo intercoolers, you will have the most robust heat exchangers available. Your engines will run cooler and your valuable assets will be protected.
