• Description


A heat exchanger is a device used to transfer heat between two or more fluids. In other words, heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment.


Graphite is characterized by its high level of corrosion resistance and its thermal conductivity is much greater than most comparable corrosion resistant materials.
Manufacturing process, of graphite raw material, requires a lot of energy during compression, baking and graphitization. A very long process which can take several months.

Impregnation of graphite will give imperviousness property. We use proprietary resin and latest technology which shorten production lead time. Three grades of impregnated graphite, using two different resin types to cover steel industry applications.

We are the second company in the world able to supply “real” PTFE impregnated graphite.

Our GT-FLON show extraordinary corrosion properties outclassing traditional phenolic resin impregnated graphite.
