PFA Coated : Metal tubes are coated with 0,5 to 0.8 mm thk. PFA (PTFE Equivalent). They are suitable for - 100°C to 200° C. for all most all Chemicals. They are food confirming. Poor heat Transfer Property of PFA is Compansated by using corrugated tube or Heat conductive steel.
Thus PFA Coated heat exchanger requires same heat transfer area as steel heat Exchanger.
This heat exchagner is having the higher heat transfer coefficient than galss, Hastelloy, titanium, Hence compared to glass, it requires 1/2 heat transfer area & compared to Hastelloy, Inconel or titanium, it requires 2/3 heat transfer area
