About Us
Madok Manufacturing Limited, located in Brantford, Ontario, is a manufacturer of custom designed copper tube/aluminum plate-fin heat transfer coils and is also the Canadian licensee for Heresite Protective Coatings, Inc.

Incorporated in 1975, our early growth was based on our ability to supply "exact" replacements, within very short lead times, for coils which had failed due to freezing, corrosion or other causes. While rapid delivery of replacement coils remains an important part of our business, we supply heat transfer coils to suit many new applications as well.

Heresite protective coatings, a logical extension of our coil business, prolongs the life of cooling and heating coils, air/fume handling equipment and other components installed in corrosive atmospheres (including salt water).
