Ceramex North America LLC is a leading diesel particulate filter remanufacturer and inspection specialist. What we’ve learned supplying exhaust and emissions systems to the aftermarket and original equipment manufacturers (OEM’s) helped us develop and patent our Xpurge® DPF/DOC Cleaning Technology. It means we can clean all types of DPF/DOC’s to the high standards required by manufacturers. We employ inspection and validation technologies designed to ensure that the cleaned filter has been returned to optimum performance.
