Plate heat exchangers designed for applications on the high seas

GEA Heat Exchangers, represented in Russia and CIS by its subsidiary GEA Mashimpeks, will present sealed, high-performance plate heat exchangers for high-level output in use with maritime engines. The models in the NT range of heat exchangers cool the light fuel oil in use; in addition, they are flexibly scalable and have a small footprint. 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. The NT range was especially developed for the requirements encountered on the high seas. Its OptiWave technology assures maximum flow over the entire plate surface and guarantees a high heat-transfer rate. The plates are exactly positioned with the aid of GEA PosLoc technology, to ensure that the seals remain fully functional longer. The result is a stable, perfectly aligned, and tightly sealed plate package.
 

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 Bloksma Box Cooler, K-type, from GEA Heat Exchangers combines various advantages used in vessels ranging from the fishing boats and cargo vessels to the dredger and workboats: a much lower power consumption thanks to thermo syphon principle in the sea-chest in stationary mode and making use of flow characteristics when the ship is in sailing mode. This is how the Box Cooler saves up to 15,000 litres of fuel per year. The system is not susceptible to galvanic corrosion and impurities. In particular, biological impurities are prevented by an Impressed Current Anti Fouling (ICAF) system. 

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. The Russian demand for new fishing ships is also growing tremendously. Over the coming years, Russian fleets have a requirement for 60 large as well as 280 small and medium-sized ships. By now, customers increasingly voice their interest for the use of ammonia (NH3) as refrigerant for on-board refrigeration. Although the Russian Maritime Register of Shipping (RMRS) has allowed the use of the refrigerant R22 until 2020, prompt refitting to an efficient alternative such as NH3 is already beneficial, environmentally friendly, and effective: after all, fishing vessels have a very long service life, and the average age of Russian medium-sized and large ships is considerably more than 20 years.  

In its refrigeration systems, GEA Refrigeration Technologies installs highly efficient screw compressors form the GEA Grasso LT range, as well as compressor packages from the SP-1 range. They are characterized by their compact design, low-vibration operation, and ease of maintenance. They are also equipped with low-friction rotor bearings and can be employed together with frequency inverters to obtain greater output and optimized operation in part-load ranges. For the control of new and existing refrigeration component systems – such as fish pre-cooling equipment (RSW), cargo holds, and freezer systems – GEA Refrigeration Technologies offers package solutions for retrofitting electrical switching systems with automated control functions and remote diagnosis via Ethernet. 
 

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. The BallastMaster ultraV has a modular design and is therefore effective for use in construction of new ships as well as for retrofitting. As part of GEA Westfalia Separator seaprotectsolutions, the BallastMaster ultraV provides you with an all-round, worry-free system which meets current and future IMO standards for ballast water treatment.
