Prime Surface Heat Exchangers

PLATECOIL®  Prime Surface Heat Exchanger

Tranter PLATECOIL® Prime Surface Heat Exchangers deliver efficient and uniform thermal control in immersion duty; jacketing vessels, reactors or dryer shells; within fluidized beds or configured as gas phase heat recovery banks. In thermal processing of any kind, PLATECOIL exchangers give you better thermal control than pipe coil, half pipe, dimple sheet or gridcoil (see pipe coil comparison below).

Processors worldwide have used PLATECOIL to:

•Eliminate sparging for reduced water and steam consumption

•Capture waste energy from moist, wet flue gases at temperatures as low as 67°C (150°F)

•Recycle low-grade heat energy from drains

•Improve economic performance in existing tanks and vessels using clamp-on retrofits

These highly versatile exchangers conform to ISO 9001 standards for design, manufacture and testing for either one-off, special fabrications or high-volume engineered subsystems. Consider all the factors—flow rate, flow balance, heat transfer coefficient, durability—PLATECOIL is engineered and crafted for faster start-ups, constant temperatures, better control and longer service life.

Engineering Shapes PLATECOIL® Efficiency

Essentially two sheets welded together, one or both of which is die-formed, PLATECOIL panels comprise a series of passages through which a heating or cooling media flows. Three styles of Multi-Zone and two styles of Serpentine flow configurations ensure that you get the right combination of flow rate and heat transfer rate with steam, gases or liquids. In designing individual solutions with PLATECOIL, Tranter engineers use advanced computational fluid dynamics (CFD) modeling to determine factors such as heat transfer coefficients and convection effects.

PLATECOIL flow patterns applied for steam provide reserve capacity to compensate for intermittent overloads during start-ups, distributing steam virtually instantaneously to all levels of the plate. Under load swings, PLATECOIL attains desired operating temperatures extremely rapidly, with minimum variation. PLATECOIL styles for liquid heating or cooling media, including hot oil or refrigerants, promote high internal flow velocities for high heat transfer rates.

More than 300 sizes are available, with widths ranging from 305 mm to 1090 mm (12 in. to 43 in.) and lengths spanning 585 mm to 3630 mm (23 in. to 143 in.). A wide variety of materials, gauges and finishes are available. Connection options are 3/4 in. to 2 in. NPT or flange.

Light Gauge, Corrosion-Resistant ECONOCOIL®

ECONOCOIL® hydraulically expanded panels are a special PLATECOIL variant available in an assortment of single-embossed or double-embossed styles and sizes in serpentine or parallel passes. Titanium construction provides long service life where highly corrosive environments exist. Light-gauge titanium ECONOCOIL panels provide better thermal conductivity than units constructed from heavy-gauge material. High turbulence results in low scaling/fouling tendency on external and internal surfaces.

Typical ECONOCOIL Applications

• Sulfate chrome plating solutions

• Chromic acid, 10% boiling

• Nickel plating solutions (except electroless nickel with fluorides)

• Inhibited sulfuric acid

• Inhibited hydrochloric acid

• Hypochlorites

• Seawater or salt brine

•  Chlorinated hydrocarbons

•  Flue gas heat recovery

• Stack gas heating

PLATECOIL vs Pipe Coil


​Multi-Zone flow arrangement for controlled steam distribution ​Controlled steam flow not possible
​Rapid removal of condensate for high heat transfer rates ​Susceptible to condensate blocking, poor heat transfer rates, waterhammer
​Factory-controlled, economical modular manufacturing ​Costly labor-intensive welding, extensive support structures
​Economical fabrication in higher alloys ​Higher alloys usually not practical or possible
​Can be formed into virutally any shape ​Limited shape possibilities
​Weighs 50-70% less ​Heavy, large-footprint fabrications, only half the surface area for equivalent footprint








Heat recovery banks made with ECONOCOIL panels capture valuable waste energy from moist, wet flue gases at temperatures as low as 67°C (150°F).
