Hi Arun,

Try FISCHER of Germany ... I believe that they made or got made some PVDF cooling/heating coils.

Certainly their U.S. affiliate could supply these. Then, of course, there are teflon type heat exchangers, too.

PVDF is supposed to go to 140 °C ... and, next to the more expensive true fluorocarbons, is highly resistant to all acids ... weakness? Probably with alkalines.

Cheers
