The Bio-Mag line of magnetic fuel-decontamination units from RCI Technologies are inline magnetic devices designed to treat microbiological contamination in fuel systems and control further growth, reducing the need for biocides and other chemicals. The device uses a magnetic field to break down bacteria so it can pass through a conventional filtration system and be consumed in the engine combustion cycle. This process inhibits further microbial growth, depleting the level of contamination in the storage tank. The Bio-Mag is available in various sizes and specifications, depending on the application, and is suitable for automotive, truck, tractor, marine, bulk storage, and other uses where bacterial contamination in fuel is a concern. The unit is a standard component in RCI’s FRS 660 automatic fuel-recirculating systems.
