Vesper™ PVDF/PFA Heat Exchangers

Vesper PVDF/PFA Heat Exchangers

The Vesper line of PVDF/PFA heat exchangers from Heateflex provide a variety of solutions for heating, cooling, and temperature trimming of fluids used in ultra-pure manufacturing processes, including deionized water, solvents, and Piranha/SC1. Models are available as stand-alone heat exchangers or as an integrated heater and heat exchanger featuring the efficient and patented Heateflex® heating coil. The heat exchanger housings are constructed with either Polypropylene, PVDF, or PFA materials, and the heat exchanger tube bundles are all-PFA for chemical compatibility. All Vesper models feature a compact design, with the maximum surface area in the smallest possible footprint to maximize heat transfer.
