Completely encapsulated with corrosion-resistant PFA and PTFE, Polytetra electric heaters are able to withstand the most aggressive chemicals over an extended period of time. They offer a long-term cost savings resulting from superior product design, construction materials and a stainless steel electrical conductor seamlessly sheathed in PFA. Polytetra electric heaters can be completely submerged in a chemical bath. 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 water-tight to the PTFE block providing unparalleled corrosion resistance. They are available in standard models from 120-600V and 350-4000 watts of continuous power. Standard lengths are between 3-15 feet and can be factory bent in any shape desired.
