An overview of Fluoropolymer heat exchangers

AMETEK Fluoropolymer heat exchangers reduce chemical processing cost in several important ways.  They will reduce downtime, lower maintenance cost, recover and save energy, and improve product purity.  AMETEK Fluoropolymer heat exchangers resist corrosion which will eliminate replacement cost, downtime or lost production caused by corrosion.

Why Choose AMETEK Fluoropolymer Heat Exchangers?

1.Resist fouling- The well-known nonstick properties of fluoropolymers resist fouling better than any material of construction yet known.  The smooth, slippery surface of a fluoropolymer helps keep tubes clean and minimizes fouling and scaling which can significantly reduce heat transfer rates in metal and graphite heat exchangers.

2. Resist shock- AMETEK Fluoropolymer heat exchangers are less subject to damage from thermal or mechanical shock than glass and graphite heat exchangers.

3Non-Contaminating- Being chemically inert, a fluoropolymer will not produce corrosion products to contaminate process streams.  It contains no binders which can leach out to degrade process fluids.

4Low Maintenance- Inherent resistance to corrosion, mechanical and thermal shock minimizes downtime for unscheduled maintenance.  Units are easily cleaned with chemical solutions which can damage metal and graphite heat exchangers.

5Easy to repair-Tube bundles in AMETEK shell and tube heat exchangers are removable and repairable.  If necessary, AMETEK Fluoropolymer heat exchangers can be repaired on site by plant personnel.

6.High Thermal Efficiency- As with other plastic materials, Fluoropolymers have a lower thermal conductivity than metal.  To offset this, tubing diameters and wall thicknesses are optimized, depending on your process, to increase heat transfer efficiency and surface area per unit volume. The outstanding fouling and scaling resistance of Fluoropolymers further enhances the thermal conductivity.  Additional heat transfer improvement is obtained with tubing of AMETEK’s patented “Q” resin, which has a thermal conductivity about double that of FEP and other conventional fluoropolymers resins.

7. Pressure drop/flow rate accommodation- While small tubing diameters provide the most cost-efficient heat transfer performance, high flow rates can sometimes result in excessive pressure drop through a single unit.  To keep pressure drop within user-specified limits at the required flow rates, AMETEK will evaluate all options, including multiple parallel units, larger tubing diameters and shell sizes, to select the lowest cost system to match the requirements of each individual application.

8. Wide temperature and pressure range- AMETEK Fluoropolymer heat exchangers can handle corrosive fluids at temperatures up to 300 Deg. F (149 Deg. C) using tubes of FEP.  The stronger, tougher “Q” series tubing extends the upper temperature limits to 400 Deg. F (204 Deg. C).  Either tubing type has a pressure capacity of over 125 PSIG (862 kPa), depending upon the fluid temperatures.  Chances are your plant can also benefit from the use of standard or custom-designed AMETEK Fluoropolymer Heat Exchangers, particularly if your heat transfer needs involve corrosive fluids.
