Immersion Coil and Shell-and-Tube Heat Exchangers produced from ultrahigh-purity PFA or FEP fluoropolymer resins are now available. Fluoropolymer heat exchangers are used primarily to heat or cool fluids used by the high-purity chemical and semiconductor industries. Typical chemicals and processes include acids used as etchants, rinsing and washing systems, and other surface treatments along with any high-purity chemical.
All wetted surfaces in contact with high-purity process fluids are in UHP materials. These corrosion-resistant units offer low extractables that do not add contaminants or detract from the effectiveness of the fluids being heated or cooled. Shell-and-tube configurations are available with nonmetallic shells to eliminate any metal presence in proximity to fluid handling processes.
These heat exchangers have been used in process applications for more than 30 years. During that time, they have proven to offer an excellent combination of low cost and high performance. They are said to be more durable and less brittle than glass and graphite and are more corrosion resistant than most metals. These units can be used for temperature control in bulk chemical storage systems or as final temperature at point of use. They are ideal for point use of generation of fluids such as ammonium hydroxide, sulfuric and hydrochloric acids, and chlorine dioxide, where the heat of dilution or reaction must be controlled.
The company also produces high-quality fluoropolymer tubing made from ultrahigh-purity resins that are available in a range of standard or custom sizes up to 2-inch diameter. The tubing can be supplied with special custom packaging and spooling and shipped to comply with specific customer JIT delivery requirements.
