AMETEK Products

Heat Exchangers for High Purity and Corrosive Applications


AMETEK Shell-and-Tube heat exchangers with tubing made of corrosion-resistant fluoropolymers are ideal for heating, cooling and condensing chemically aggressive and high purity process streams. Typical applications include: Dl water and other high purity solutions; sulfuric, hydrofluoric, nitric, hydrochloric and other acids; caustic and other alkalis; halogenated compounds; salt solutions, and organic compounds.

AMETEK Shell-and-Tube heat exchangers are single-pass designs incorporating flexible fluoropolymer tubing fused at both ends to form a honeycomb structure. Units are also available with fluoropolymer-lined shells for high efficiency heat interchange between two corrosive process streams; an ideal way to recover waste heat and to reduce energy costs.


Shell diameters for standard units range from 3 to 14 in. (76 to 350 mm); shells are available in carbon or stainless steel, fibreglass or other materials. Nominal tube length is from 2 to 24 ft. (0.6 to 7.3 m). Tubing diameters range from 0.10 to 0.375 in. (2.54 to 9.5 mm) in either FEP or Q-Series models.

Heat Transfer Area - 5.1 to 1104 ft2 (0.5 to 103 m2) in standard units.


AMETEK Minicoils made with fluoropolymer tubing are used to control temperatures in laboratory baths and small production tanks where corrosion is a concern. Applications include etching, precious metal plating, and D1 water rinse tanks in semiconductor manufacturing.

FEP or Q-Tubing laced to support sheets forms a compact, lightweight design that resists contamination and prolongs the service life of the installation. High thermal efficiency means smaller units requiring less tank space. Minicoils are available in several coil configurations.


Available in 12, 15 and 18 inch sizes.

Heat Transfer Area-from 2.1 to 10.0 ft2 (0.195 to 0.929 m2).

Fluoropolymer Tubing

AMETEK Fluoropolymer Tubing provides excellent mechanical, electrical, chemical, corrosion, and friction resistance, and is ideal for high purity electronic, medical, food and beverage, chemical and other applications. AMETEK Fluoropolymer Tubing is available in industrial and heavy wall thickness, standard and fractional sizes. Temperature ranges are from -275° to 400° F. Available in FEP, PFA, TEFZEL® and high purity PFA resins.

Reactor Coils

AMETEK Reactor Coils are designed for immersion heating and cooling of corrosive fluids in agitated process vessels or storage tanks. Reactor coils are ideal for crystallization of corrosive liquids including: removal of Glauber's salt (sodium sulfate decahydrate) from rayon spin baths; removal of sodium chloride in purification of 50% caustic; separation of iron sulfate from spent pickle liquor. During the crystallization process, the slippery fluoropolymer tubing flexes from agitation causing crystals to dislodge. The heat transfer characteristics permit precise control of crystal size while improving crystallization efficiency.


Reactor coils are available in lengths from 4 to 16 ft. (1.2 to 4.9 m), with bundles of 160 to 500 tubes, 0.1 or 0.125 in. (2.54 to 3.12 mm) in diameter. End connections can be either PTFE or stainless steel and can be mounted completely immersed in a process solutions or through a vessel wall.

Heat Transfer Area - from 14 to 245 ft2 (1.3 to 22.8 m2).

Slimline Coils

AMETEK Slimline Heat Exchangers are widely used in the metal finishing and processing industries and are especially suited to steel pickling applications. The basic properties of fluoropolymers resist corrosion and combat fouling, extend heat exchanger service life, and improved value-in-use through reduced maintenance costs. AMETEK Slimline Q-Series heat exchangers are made from a proprietary resin that combines improved durability with increased temperature and pressure capability, delivering high thermal efficiency and performance.

Q-Series coils handle steam heating applications without de-superheating and are especially suited to batch and continuous pickling applications.


Slimline Coils are available in lengths from 4 to 16 ft. (1.2 to 4.9 m) in U-shape and straight configurations. Slimlines are available with FEP or Q-Series tubes.

Heat Transfer Area - 34 to 255ft2 (3.2 to 23.7 m2)


AMETEK Supercoil Heat Exchangers are designed for heating and cooling a wide range of metal finishing solutions. Supercoil applications include: electroplating, electroforming and electroless plating baths; acidic and alkaline solutions for etching, chemical milling, anodizing, cleaning, stripping, electropolishing and similar operations.

AMETEK Supercoil designs incorporate bundles of flexible, multi-braid 3-1/2 inch (89 mm) thick coils which can be installed intro virtually any type of tank configuration. Braids are separated by spacers for optimum thermal performance. The inherently high electrical resistance of fluoropolymers help Supercoils resist the effects of stray currents in electroplating tanks.


Supercoils are available in lengths from 3 to 16 ft. (0.9 to 4.0 m) with 100 to 280 tubes of FEP or Q-Series resin; tubes are 0.10 in. (2.54 mm) in diameter. End connections are available in PTFE or stainless steel.

Heat Transfer Area - 6.5 to 113ft2 (0.6 to 10.5 m2)
