  • Maintenance : remplacement of the anodes every 12 to 24 months depending on conditions of use.

  • Price : 3950 € HT (SRAF + rectifyer)
  • Installation : to be estimated 
  • OPTIONS : Aluminum anode for protection of steel hull against corrosion :
    2000 € HT.
  > The SRAF is efficient on all materials

The SRAF protects efficiently all hull materials : wood, polyester, steel, bronze, aluminium, plastic, rubber, etc.

  • No risk of corrosion
    This system does not interfere with standard cathodic protection, and has no corrosion effect on aluminium parts.

  > Constant protection

The function of the SRAF is regulated by a rectifyer, which operates in alternating intervals. This alternating protection reduces considerably the energy consumption, while allowing the electrolysis system to destroy the copper ions produced for protection, so they are not harmfull for the environment.

  > All waters
  • Sweet or salt water
    A simple adjustment of the rectifyer is necessary to insure protection in all different water types.

  • Clean or dirty
    Chemical products which could be found in water (fuel, soap, etc.) do not create any interference with the protection system.
    In addition, in case the SRAF should be positionned at the bottom under the boat, even under 20 cm of slurry, protection would be assured.
   > Other uses
  • Ports : This product is available in a portable version for moored boats, or in a fixed version for harbours and marinas. Part or all mooring areas could then be protected permanently from organic growth and damage.
    .
  • Piscines, bassins, aquariums, etc.

   > Tests and projects
  • The KNRM (Royal Netherlands Sea Rescue Institution)

    For our tests, we have equipped a Deutch rescue ship with the SRAF system.
    This boat belongs to the "Royal Netherlands Sea Rescue Institution (KNRM)". 
    They operate with 16 meter boats along the shore and nearby canals. They are made of both inflatable and rigid materials (aluminum), and are not painted. Therefore, they require a strong protection when moored along metallic pontoons.

 Picture of the hull after 10 months at sea

The boat has stayed 10 months in sea water. The hull was totally clean when the boat was uphauled for inspection. 

After the success of this test, the KNRM is currently looking for a mean to finance a global protection with the SRAF system for their complete fleet.



 

  • Dutch Navy
    The "Dutch navy" projects to use the SRAF system to protect their ships, harbours and pontoons. This proves that the SRAF system can be used professionnally to protect all sorts of immerged equipments.

  • Medembik harbour
    With the use of SRAF's anti-fouling system a whole harbour can be protected against fouling. SRAF made plans to protect the whole harbour of Medembik in the Netherlands. Frames will be installed alongside the quays. In this way all the anchored vessels are protected. The frames are lowered in the water and are connected to their controllers in a central case. This system improves the quality of the harbour tremendously.
