Heat Exchanger Materials

Heat exchangers are typically constructed of copper cooling tubes or of a copper nickel alloy called cupro-nickle. The copper nickel alloy is most commonly done in a 90/10 ratio although 70/30 is available in limited applications. Heat exchangers built from 90/10 cupro-nickle tubes offer increased resistance to salt water corrosion and biofouling. Cupro-nickel does not corrode in seawater, because its electrode potential is adjusted to be neutral with regard to seawater. 

What is a Heat Exchanger?

A heat exchanger is simply a device built for efficient heat transfer from one type of medium to another. Heat exchangers can be used to cool or to heat other devices.  Examples of this abound in our personal life as air conditioning, refrigeration, heat pumps, heaters, radiators and other heat exchanger systems. The radiator in an automobile is a heat exchanger that transfers heat from the coolant which first flows through the engine block, gathering heat. The coolant then flows from the engine to the radiator where air flowing through the radiator fins removes some of the heat. The passenger heater in a car is also a heat exchanger.

Boats rarely have automotive style radiators because clean, steady air flow is too hard to attain. Instead of air moving across a heat exchanger, marine engines use the water the boat sits in to cool the hot engine fluids and exhaust gasses. In marine use, there are two primary ways to cool an inboard or I/O engine. These engines may be cooled with outside water running through the block and exhaust, this is a raw or sea water system. A sealed system of coolant cycled through the block and then into a heat exchanger which is cooled by external water is called a fresh water cooling system. You can also cool any type of oil – motor, hydraulic, power steering, transmission – with an oil cooler.

Fresh Water Cooling Systems

Conversion to a fresh water cooling system is typically done for boats being used in salt water. A Fresh Water Cooling System is a heat exchanger with all the parts to convert a raw water system to a closed loop cooling system. Beyond the heat exchanger, there is some plumbing and parts needed to install the system, including; belt driven raw water pump, heat exchanger mounts, gaskets, thermostat, thermostat housing, hoses, hose clamps, hose fittings, & fasteners. The biggest advantage of a fresh water cooling system is an increased life of all engine parts that were once in contact with the raw sea water. With fresh water cooling, there is reduced galvanic action to the engine cooling system.

Custom Built Heat Exchangers

Custom heat exchangers from Seakamp are available for varied vessel applications. Heat exchangers can be built to match:

  • The vessels engine displacement and horsepower
  • Hose connections to match the Inlet and Outlet for the engine
  • Hose connections to match the Inlet and Outlet for the Raw (Sea) Water
  • Outside Diameter of heat exchanger
  • Orientation and installation – vertical or horizontal
  • Flow rates and system pressure
  • Typical raw water operating temperature

pompacEven though the season is cooling off, it is a great time to install a built in, ‘central air’ style Pompanette Air System for your boat. These systems will help cool your boat in the summer AND heat your boat in the winter in water temperatures of 45 F or better. Go2marine is proud to offer these custom air systems that are specifically designed and fitted to each boat.

Because each system needs some custom installation, the winter season is the right time to have the work done. Go2marine is here to make chosing the correct system easy for you with our enquiry form.

Pompanette Air Conditioners feature:

  • Vibration absorbing chassis design, using state of the art composites
  • Energy absorbing insulators, to reduce the “White Noise” of Air Conditioning
  • Quiet Rotary compressors
  • Ultra-High Efficiency enhanced surface air coils
  • Exclusive and patent pending condensate management system
  • Cupro-Nickel sea water Condensing Coil / Heat Exchanger
  • Pre-Wired meeting or exceeding the latest industry criteria

Before they leave the factory, each unit is individually tested to exacting standards.
