PLATECOIL® Prime Surface Heat Exchangers combine flexibility and functionality to deliver more efficient, economical, and uniform heating and cooling to any application. Customers worldwide improve performance with panels bent, rolled, or otherwise formed into wide-ranging configurations. These highly versatile heat exchangers adhere to the highest standards for design, manufacture, and testing in the industry.

PLATECOIL® is a very efficient and versatile light-duty plate-type heat exchanger. Its unique construction enables high heat transfer efficiency for heating and cooling, which can be applied to a wide range of applications. Units are commonly used in plating, metal finishing, chemical processing, pulp & paper, waste treatment, textiles, pharmaceutical, and food & beverage industries.

PLATECOIL® is fabricated from two sheets of metal using a fully computerized welding machine that uses electric roll spot resistance welding. The plate is then hydraulically inflated, forming a variety of flow patterns. Each ECONOCOIL® plate is designed and constructed to match the needs of each application and requirement. With success stories spanning 70-plus years, PLATECOIL® versatility finds its way into new applications and industries each year.

Manufacturing of

PLATECOIL®

The sheet material is pressed to form “corrugations” called embossings.
Embossings are either seam welded to each other to form “double
embossed” coils, or to a flat sheet to form “single embossed coils.
Fittings are attached to provide an inlet & outlet for fluid internal to the
PLATECOIL®.
Carbon steel, 304, and 316 stainless steel are the standard materials of
construction.

Other alloys that can be cold-formed and welded are also used:

Monel
Inconel
Hastelloy
Alloy 20Cb-3
254-SMO
AL6XN
Titanium

Resistance Welding of

PLATECOIL®

Continuous electric resistance welds are used for perimeter and pass joining.
Machine welds are consistent, accurate & not susceptible to human error in manual welding processes.
Weld wheels apply electrical and mechanical pressure from BOTH SIDES
of the Plate.

PLATECOIL® Styles and Explanation

Multi-Zone

The passages formed by the embossings are designed to provide PLATECOIL® users with a choice of two basic flow patterns, depending on the application. PLATECOIL®’s Multi-Zone flow configuration is ideal for use when steam is the heating medium. The Serpentine flow configuration finds wide application with liquid heat transfer media such as water, oil, and liquid refrigerants.

With its zoned header design, Multi-Zone PLATECOIL® provides far more heat transfer efficiency than pipecoil or units with straight headers in applications requiring the use of steam. The Multi-Zone headers and flow arrangement provide controlled distribution of the steam as it flows through the PLATECOIL®. The rate of condensate removal from the passages or passes is significantly increased as compared to units with straight headers. Efficiency-reducing condensate blocking is minimized. As a result, Multi-Zone PLATECOIL® provides faster heat-up and better heat transfer rates.

Serpentine

PLATECOIL® with a Serpentine flow configuration provides outstanding performance with liquid heating or cooling media because its configuration allows high internal flow velocities to be achieved. As a result, high heat transfer rates can be obtained. Serpentine PLATECOIL® is frequently specified for use with cold water, high-temperature hot water, hot oil, and refrigerants. When used with refrigerants, the Serpentine flow design offers the additional advantage of eliminating the possibility of “short-circuiting”.

Standard Styles, Sizes & Fabrications

Both Multi-Zone and Serpentine double-embossed PLATECOIL® are available in over 300 standard sizes. Several styles are also offered in a choice of either carbon steel or Type 316L stainless steel. Standard PLATECOIL® are available in over 300 sizes; widths range from 12” to 43”. Length dimensions range from 23” to 143”. A variety of standard PLATECOIL® fabrications, such as drum warmers, vessels, suction heaters, and screw conveyor troughs are also available. These pre-engineered units are designed to satisfy a wide range of heating and cooling requirements in industrial process applications.

Special Designs Features

PLATECOIL® can be bent, rolled, or otherwise formed into virtually any configuration. It has inherent flexibility. In addition to carbon steel and stainless steel, PLATECOIL® can be fabricated from such materials as Monel, nickel, and a variety of other corrosion-resistant materials. Flow configurations, other than Multi-Zone and Serpentine, can be specified to meet special design and performance requirements. Several types of surface finishes can be provided to minimize fouling and reduce maintenance. Large pass, heavy gauge PLATECOIL® is another option available to satisfy requirements for high internal flow rates, low-pressure drops, and rugged use. A variety of standard PLATECOIL® fabrications, such as drum warmers, vessels, suction heaters, and screw conveyor troughs are also available. These pre-engineered units are designed to satisfy a wide range of heating and cooling requirements in industrial process applications.

PLATECOIL® Accessories & Options

With each PLATECOIL®, we can offer a range of options and accessories to assist Installation and improve performance. For PLATECOIL® to be used in tanks, we offer handles and hangers so they will be correctly positioned and can easily be inserted and removed. For clamp-on applications, we offer Konduct No.1 Heat Transfer Cement to assist with heat transfer. Additionally, we supply lugs with tie bolts to securely fasten the PLATECOIL® to surface sides.

We can also supply special connections & flanges for the units. The table shows some standard flanged connections we can provide, but please contact us if you have a particular need.
