On the occasion of NEVA 2013, the International Shipping, Shipbuilding, and Offshore Energy Exhibition, GEA Heat Exchangers, GEA Refrigeration Technologies and GEA Westfalia Separator Group will present solutions for maritime applications.Plate heat exchangers designed for applications on the high seas
These heat exchangers provide dedicated cooling of engine fuel, which reduces the viscosity below the level recommended by leading engine manufacturers. In addition, the fuel burns with less residue and emits less pollution. These plate heat-exchanger coolers are externally installed, which enables retrofitting without difficulty. No modifications are necessary for the engine itself.
Oil cooler for enhanced heat transfer
Using water as coolant, the Bloksma NF oil cooler from GEA Heat Exchangers can efficiently cool oil in turbines, diesel- or gas-powered engines, gearboxes, bearings, hydraulic- and refrigeration plants or compressors. Plate fins on the oil-conducting tube bundles offer a large heat-transition surface and enable enhanced heat transfer. The NF oil cooler comes in four different sizes, all of which are insensitive to impacts, vibration or pulsation.
Saving fuel with Box cooler
The unique principle of boxcooling: cooling water is forced through a U-tube-bundle, which is placed in a sea-chest having inlet- and outletgrids. The cooling effect is reached by natural circulation of the outboard water in the sea-chest or by a circulation due to the speed of the vessel. The outboard water is heated and rises by its lower density, thus causing a natural upward circulation. Box coolers are available in a round version for small capacities, and a rectangular version for larger capacities. It is possible to connect more coolers in series or parallel in case one cooler does not have enough cooling surface. Up to date, more than 20.000 box coolers have been supplied and are operating successfully.
Technologically mature refrigeration systems for customized ship refurbishment and new construction
Retrofitting older fishing vessels with advanced refrigeration systems - the experts at GEA Refrigeration Technologies have long since mastered this challenge. Since 1996 they have retrofitted more than 50 ships - most of them from Russian fishing fleets - with advanced refrigeration systems from German engineering and production
Highly efficient ballast water treatment without the use of chemicals: GEA Westfalia Separator BallastMaster ultraV
With its new BallastMaster ultraV, GEA Westfalia Separator Group once again demonstrates that its new developments are close to the customer and right in line with market needs. For example: treatment of ballast water on board takes place in this system entirely on the basis of filtration and irradiation with UV-C light - i.e., completely without the use of chemicals. Since the self-cleaning system for the lamps is based on ultrasonic technology, no disinfection by-products are produced.
