Filtering the ballast water and treating it with high concentrations of UV light to kill organisms and microbes is an environmentally friendly method. An appropriate system with a UV reactor is installed, usually in the central pump room. This room is classified as a hazardous area in oil tankers, floating oil production platforms, and ships carrying combustible materials. High voltages are needed to operate the UV reactor, Pepperl+Fuchs has developed a certified solution that combines a purge and pressurization system with other explosion protection equipment. This certified solution creates safe environments to operate high-voltage electrical equipment.
The central component of the solution is a purge and pressurization system. The purge and pressurization system from the Bebco EPS® 6000 series product range protects the electronic components in the reactor and the UV lights. To do this, the system automatically establishes the necessary overpressure and monitors it continuously. By purging with an inert gas, any ignitable gases and vapors are reduced to a concentration that is no longer explosive.
The purge and pressurization system is supplemented by an explosion-protected junction box and control components. Pepperl+Fuchs offers pressure measurement sensors, fill level sensors, temperature measurement sensors, and K-System junction boxes for intrinsically safe signal transmission. This customized, internationally certified solution is ready for connection and comes in explosion-protected housing.
