Kammpro ACHE is specially designed to replace traditional solid metal "washer" type gaskets typically used in air cooled heat exchangers. The design takes advantage of the serrated profile with graphite facing to bite against the finish of the header plate and fill in the voids, creating a superior level of tightness. The Kammpro-ACHE has proven to be a very viable solution to emission concerns found where optimal conditions for metal-to-metal sealing are not realized.
