The marine and naval sector involves various cooling and temperature control applications, with the use of thermoregulation units and heat exchangers. Applications include cooling of engines and on-board electronics, electric drives in modern hybrid boats, servers and power inverters. A whole series of devices and equipment that generate large quantities of heat that must be dissipated.
To dissipate the great amount of heat generated by yachts and boats, special cooling systems are studied, such as exchangers placed under the hull called keel coolers, which exploit sea water to cool the utilities on board, but also auxiliary chillers installed on the ships.
The most advanced hybrid or hydrogen propulsion technologies in zero-emission yachts therefore open very interesting fields of application for PCHE exchangers, ideal for cooling hydrogen in the electrolysis process that powers fuel cells, with green hydrogen obtained directly from sea water.
Examples of applications in the marine sector:
Off shore application can be cooled with plate heat exchangers.
SHIP motors are directly cooled with sea water, using titanium plate heat exchangers.

Fresh Water Distillers Spare Parts
The fresh Water Distiller works on the well-known vacuum distillation principle. Waste heat from the main engine on board is used as heating medium for evaporation.
The plates type Fresh Water Distiller is based on two plate stacks.
The evaporator chamber is kept under vacuum by a water ejector driven by the seawater from the condenser.
Part of the heated seawater is used as feed water for the evaporator. On entering the evaporating chamber this water evaporates due to the vacuum. A deflector and builtin de-mister removes any water droplets still present.
These fall back into the brine, which is extracted from the sump by an ejector pump. The desalted water vapour is condensed in the plate condenser using cold seawater.
