Seawater-resistant enclosures for shipbuilding

ROSE Systemtechnik sets standards in the development and provision of robust enclosure solutions that are specially designed to withstand the extreme conditions in harbours, on ships or in water sports facilities.

Our high-quality protective enclosures not only offer first-class corrosion resistance to salt water, but also outstanding performance in terms of watertightness, UV resistance, temperature resistance and resistance to chemicals.

Basically, two types of enclosure are particularly suitable for use in water: stainless steel enclosures and aluminium enclosures. We process both our standard designs and a customised solution according to your requirements so that they reliably withstand the influences of water. To achieve seawater-resistant corrosion protection, our aluminium housings are passivated in an automatic continuous flow system. Due to their material properties, stainless steel housings are already seawater-resistant even without treatment.

We subject the finished housings to a salt spray test in accordance with EN ISO 9227.

We offer these versions:

  • SWB

    Seawater resistant with a powder coating

  • SBG

    Seawater-resistant with a primer

  • SBGL

    Seawater-resistant with a primer and top coat

Which design is best for you depends on the application. We will be happy to advise you. Find out more about our customised development service here.

Processing of seawater-resistant aluminium enclosures

  • Cleaning and degreasing
  • Passivation or chromatisation
  • Priming with a 2K primer thick layer
  • Coating with top coat and hardener
  • Follow-up treatment
  • Polyester powder coating

    As standard in the colour RAL5009 or according to customer specification

The form in which a enclosure is processed depends on the desired seawater-resistant design (SWB, SGB or SBGL) or the area of application. Our global development service is on hand to advise you.

Stainless steel enclosure V4A

 

V4A is a German standard that stands for “Versuchsstahl 4 Austenit”.

In the international standard, this is often referred to as “AISI 316” or “UNS S31600”.

V4A stainless steel is particularly resistant to corrosion and is often used in environments where high resistance to chemical attack, acids or salt water is required.

This means that the robust stainless steel housing is already extremely resistant to seawater even without additional treatment.

Seals and mounting components

  • PU foam seal
  • Neoprene seal
  • Silicone round cord seal
  • Cover screws, flange screws and metal cable glands with greased thread
  • Seawater-resistant treated earthing points
  • Completely coated outer joints
  • Non-coated internal joints

Ex enclosures for maritime applications

Protective enclosures that are both seawater-resistant and explosion-proof must be integrated on a ship or in offshore installations, as the extraction of highly flammable substances such as oil, gas, LNG or hydrogen often begins in rough waters. The propulsion of ships also harbours the risk of ignition.

Depending on where a protective housing is integrated, it must either protect the inside of the housing from external flames or shield a fire inside the housing from the environment.

The same materials (aluminium or stainless steel) are used as for normal SWB enclosures and are also made corrosion-resistant with the aid of passivation. However, the construction, seal and installed components are designed for possible explosions and have ATEX and Ex i approval. If the installed parts do not have Ex approval, an Ex d enclosure is required to withstand an explosion inside and protect the environment.

Areas of application for our maritime enclosures:

  • Interior areas of ships, boats and submarines
  • Exterior areas of ships
  • Offshore facilities and harbours
  • Water and amusement parks or swimming pools

Protection classes and approvals

In maritime environments, protection against water must be particularly high, as salt water is corrosive and can severely affect electronic devices.

IP protection classes such as IP65, IP66 and higher are particularly relevant for protection against water. IP65 offers protection against water jets from any angle. For marine applications, however, a higher protection class such as IP67 or IP68 should often be considered to ensure reliable protection against water ingress, even when submerged. The enclosures from ROSE Systemtechnk already have protection class IP66 as standard.

Higher protection classes are possible with appropriate seals. ROSE Systemtechnik will advise you which IP protection class is required for the use of your customised SWB enclosure and will develop a solution that meets all requirements.

Approvals for seawater-resistant enclosures

  • IP 66
  • IP 67
  • IP 68

Ex stainless steel

The Ex stainless steel enclosures are high-quality enclosure systems in accordance with the ATEX and IEC directives. They are particularly suitable for use in harsh and aggressive environments, such as near seawater, in areas where maximum purity and cleanliness are required and for EMC applications.
