DESMI Ocean Guard’s ballast water treatment system (BWTS), RayClean-EX, has received ATEX certification, enabling it to be installed directly into hazardous areas onboard tankers.
The RayClean ultraviolet (UV) unit and the UV control panel powering the unit have been certified, therefore both components can be installed in hazardous areas onboard vessels including oil tankers, chemical tankers and gas carriers.
A purge and pressurisation method has been used to allow all potential ignition sources to be covered by enclosures that are purged and pressurised with air, which means that an overpressure can be maintained inside the enclosures. This way gas cannot access the enclosures and get close to potential ignition sources. The overpressure is constantly monitored and if it disappears the RayClean-EX system will automatically de-energize immediately.
In addition, the filter, valves and sensors in the RayClean system can also be delivered in ATEX certified version, meaning that all components of the RayClean system, aside from the main control pane, can be installed directly in the hazardous areas. This main control panel must instead be installed in a safe area, such as an engine control room.
For DESMI, this certification opens up new market segments for their BWTS.
