The certificate covers both the RayClean UV unit and the UV control panel powering the UV unit, and enables both these components to be installed in hazardous areas onboard tanker vessels like e.g. oil tankers, chemical tankers and gas carriers. The filter, valves and sensors in the RayClean system can also be delivered in ATEX certified version meaning that all components of the system except the main control panel can be installed directly in hazardous areas. The main control panel must be installed in a safe area like e.g. engine control room, which in general is the normal approach. The RayClean Ballast Water Treatment is based on mechanical filtration and UV treatment. The system has received IMO, DNV-GL and ClassNK type approval, as well as AMS acceptance by the USCG, which is valid in all salinities ranging from freshwater to marine water. Moreover, the RayClean approvals contain no limitation with regard to temperature of the water to be treated, and they cover a record setting wide UV-Transmission range, which the RayClean system has been proven capable of dealing with. DESMI says this means that the RayClean system can also treat extremely dirty and unclear water that no other UV system on the market today is approved for.
