Consisting of a stainless steel electrical conductor seamlessly sheathed in PFA, Polytetra heaters are fully encapsulated with corrosion-resistant PFA and PTFE.



Asahi/America has expanded its line of engineered fluid flow products to include Polytetra electric heaters. Consisting of a stainless steel electrical conductor seamlessly sheathed in PFA, Polytetra heaters are fully encapsulated with corrosion-resistant PFA and PTFE and so can withstand aggressive chemicals over an extended period of time.

The heaters can be completely submerged in a chemical bath because the connections from the stainless steel conductor to the electrical cord are housed within a machined PTFE block. The connection between the PFA-covered conductor and electrical cord are welded watertight to the PTFE block.
