Model PCB-200 - Dechlorination System Brochure

Polychlorinated biphenyls (PCBs) are man-made chemicals that were first synthesized in the 1880s. They have excellent properties (fire-resistant, highly stable, insulating, low volatility) that define them to be ideal for use in electrical transformers. Generically known as Askarel, they were found to be toxic and their by-products can be fatal. However the very properties that make them so desirable as a medium in electrical transformer and capacitors make their disposal very difficult*. Production of PCBs was banned in North America in 1977 and most of the approximately 650,000 ton manufactured has been accounted for.
