GF Piping Systems”CALORPLAST thermoplastic, all-welded heatexchangers are designed for heating or cooling in highly corrosiveapplications. The product line includes immersion,shell-and-tube, tube-plate, gas-liquid, and flexible heatexchangers. Materials of construction include PVDF(polyvinylidene), polyethylene, and polypropylene. Theseexchangers are a good fit for a variety of heating or coolingapplications, including heating of pickling acid solutions,electroplating, anodizing, removing heat from chemical dilutionreactions, and for acid recovery systems. The heating/coolingmedia can include saturated steam or hot water up to 35 PSIG at 281 F andchilled water or water/glycol solutions. Performance characteristicsinclude chemical inertness, no stray currents, all-weldedconstruction, low fouling, low pressure drops, and large heat transferarea in a confined space with a self-supporting structure.
