HARSONIC® FOR BOXCOOLERS
On a seagoing vessel there is in general a lot of cooling required. This is done traditionally, by using seawater, bringing into the vessel through the sea chest, and then use this seawater for cooling.
In principle, a boxcooler is a pipe bundle, as known from tubular heat exchangers, which is put direct in the seawater, whereas the seawater can be used direct for the cooling of the different processes on a vessel. These pipe bundles are installed in special compartments, where the ship is open to the sea, so all time seawater is around the tubes of the box cooler.
Bringing in huge amounts of seawater inside a vessel, boxcoolers are always potential fouling victims. Barnacles, mussels, algae, and other types of shellfish grow on the tubes of the boxcooler and thus affect its heat transfer function.
Harsonic for Boxcoolers protects 24/7 the boxcooler on low voltage, the sea-chest and the cooling tubes remain free of growth and biofilm.
- Harsonic® for Boxcoolers gives increased cooling efficiency and improved reliability
- Harsonic® for Boxcoolers means substantial savings on maintenance costs and there is no need for dry docking
- Harsonic® for Boxcoolers avoids the use of chemicals and protects the environment
HARSONIC® FOR PROPELLORS
A propeller is exposed to all sorts of attacks underwater, such as rusting and adhesions of the sea. It is the key piece of the ship’s propulsion system, and thus deserves special attention. A propeller in poor state is a disaster. To continue to use a very dirty propeller is like driving your car on a road that’s in very poor state and full of potholes. We know that very dirty pieces of equipment notably reduce the displacement of the ship. And the same thing happens with the propeller because, although its surface is a lot smaller than that of the ship’s wet hull, its surface area is multiplied by its many revolutions at high speed. The objective is that it should always be clean of horrible incrustations and calcareous deposits.
HARSONIC® FOR FUELTANK & WATERTANK
The fuel on commercial ships is continuously re-circulated and exposed to extreme pressure and heat, which results in the agglomeration of asphaltenes. It leads to the formation of larger and larger clusters and solids, which are very difficult to completely combust. These solids may grow so large that they will not pass through the filter element. They become part of the polymer and sludge build up plugging the filter.
More than 90% of the debris on filter elements and the sludge in our tanks is organic material: fuel and oil breakdown residue. Adding biocide does not help! In most cases, this debris is acidic and not good for your engine. It causes corrosion in injectors, pumps and storage tanks. In addition, the hot fuel coming back to the tank will raise the fuel temperature in the tank, cause condensation and contribute to microbial contamination, fuel break down, bio fouling and the build up of sludge and acid.
Advantages of Harsonic® for gasoil-tanks:
- Less loss of engine-power
- Less excess engine-smoke
- No more slimy and dirty or even clogged fuel filters
- Environmentally safe and friendly
- Very low power consumption
HARSONIC® FOR HULL
The current solutions are often not effective and harm the environment.
Harsonic® avoids the initial step of the fouling, called biofilm. Eliminating the biofilm prevents the development and the attachment of barnacles, mussels, oysters and algae.
Fouling begins with a layer of slime of biofilm. This slime paves the way for plants and animals to attach. The amount increases over time. Organisms like barnacles, mussels, sponges, algae and sea squirts attach themselves to the hull and propeller of ships.
Fouling can negatively affect the fuel efficiency, speed and cause increased maintenance costs to remove the fouling.
Fouling attached to hull for too long you can damage the paint and cause deterioration .
Harsonic® avoids growth of biofilm-producing bacteria and fungi and biocorrosion in hydraulic- and lubrication oil systems in offshore installations and ships.
By means of Harsonic® there is a much greener and efficient solution than ionization or cathodic systems.
