Asahi/America has expanded their line of engineered high purity and industrial fluid flow products to include Polytetra Series shell and tube heat exchangers. Polytetra Series are all-thermoplastic, corrosion resistant heat exchangers that are designed and built per customer specification, and are fully customizable. Polytetra Series heat exchangers feature an industry leading design that diverts flow to the side of the shell, avoiding high fluid flow forces that may damage the thin-wall internal tubes of the shell and tube style heat exchanger. This design provides longer life and more even heat transfer by spreading the temperature control media beyond the point of its initial concentrated contact area. Available in PFA, E-CTFE, PVDF and PP, the all-thermoplastic Polytetra tube and shell heat exchanger is an ideal solution for otherwise corrosive environments. Ideal for electroplating industries and clean chemistry applications such as photovoltaic and semiconductor processes, Polytetra heat exchangers are available in a variety of designs and sizes. Thin wall tubing made from specially matched
resins to fit Asahi Piping Systems Heating/Cooling media does not wear directly
on process tubing High coefficient of heat transfer Custom designed to meet customer needs
Polytetra Series shell and tube heat exchangers are specified and installed with confidence throughout the world. Designed specifically for each customer ensuring proper heat exchange rate. Available with both ends welded and one or both ends flanged for cleaning. Completely customizable end and top connections and top orientations.
