At Marintec 2013, GEA Heat Exchangers will show cooling solutions for maritime applications – including its Box Coolers, exhaust-gas recirculation coolers, and reliable plate heat exchangers. The GEA Bloksma Box Cooler combines various advantages employed in seagoing vessels: ranging from workboat[ds_preview]s such as tugs and offshore-platform supply vessels, to cargo vessels and dredgers. It offers significant reductions in fuel consumption due to its lack of seawater pumps, the company underlines. This means that use of Box Coolers on board can save up to 15,000 l of fuel per year.
With its fully welded exhaust-gas recirculation cooler, GEA Heat Exchangers furthermore presents a new cooler generation for large maritime diesel engines that allows reduction of NOx emissions. With these packages, the new technology allows a mixture of recirculated exhaust gases with fresh charge air, at low temperatures. The exhaust-gas recirculation cooler lowers the temperature of hot exhaust gases (some as hot as 700 °C) down to 50 °C, before they are recirculated and mixed. The compact heat exchanger is made of stainless steel, resistant to temperature and corrosion effects. Gas and water connections are matched to customer requirements, which means that these units can be retrofitted to already installed large diesel engines, GEA states.
The EcoFlex NT series of heat exchangers is designed specifically to the marine cooling or heating duties and offers robust and compact product solutions suitable for ships and offshore installations. The heat exchangers cool or heat various onboard applications such as central cooling, jacket water cooling, lube oil cooling, engine fuel heating/cooling, and tank cleaning heating. The EcoFlex NT series was specifically developed for the requirements of offshore and commercial marine environments.
