Shell & Tube

CG Thermal’s Impervite® shell and tube heat exchangers are designed to be the “work horse” of the industry. Utilizing our proprietary grade of phenolic impregnated graphite it offers excellent service life in corrosive condensing, vaporizing, absorbing, heating and cooling applications. Compared to other graphite heat exchanger designs it has competitive capital investment cost, high reliability, and high return on investment.

Impervite® is a composite material consisting of a graphite substrate impregnated using a proprietary phenolic impregnation process. Impervite is ideally suited for processing mixed acids, sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, waste acids, and chlorinated hydrocarbons. It has excellent machining, physical, and thermal properties.
