Plate Coils
Plate Coils are versatile heat exchangers designed for efficient heating and cooling in various industrial applications, including metal finishing and electroplating. These coils are known for their high heat transfer rates and are customizable to meet specific process needs. Whether you require Plate Coils for jacketed vessels, clamp-on panels, or immersion heaters, our solutions are engineered to enhance your process efficiency and performance. With configurations like Multi-Zone and Serpentine, Plate Coils are available in a range of materials, including carbon steel, stainless steel, and corrosion-resistant alloys, ensuring durability and reliability even in the most demanding environments.
When selecting Plate Coils, consider the following factors to ensure they meet your specific application requirements:
- Configuration Type: Choose between Multi-Zone and Serpentine flow configurations based on your heating or cooling media.
- Material Selection: Specify the material based on your process environment, such as carbon steel, stainless steel, or other corrosion-resistant alloys.
- Application Type: Determine the application, whether for metal finishing, electroplating, or other industrial processes.
- Size and Dimensions: Provide the required dimensions and any specific design requirements, such as single or double-embossed styles.
- Accessories: Identify any accessories or options needed for installation, such as handles, hangers, or special connections.
Plate Coil Models and Configurations
Multi-Zone Plate Coils
Multi-Zone Coils are designed for use with steam as the heating medium, making them ideal for applications that require efficient heat transfer. The zoned header design of Multi-Zone Plate Coils offers superior heat distribution compared to traditional pipe coils. This configuration minimizes condensate blocking, leading to faster heat-up times and better overall heat transfer efficiency. Multi-Zone Plate Coils are particularly useful in processes like metal finishing and electroplating, where consistent and rapid heating is essential.
Serpentine Plate Coils
Serpentine Coils provide exceptional performance when using liquid heat transfer media, such as water, oil, or refrigerants. The Serpentine flow design allows for high internal flow velocities, resulting in enhanced heat transfer rates. This configuration is often selected for applications that involve cold water, high-temperature hot water, or refrigerants, offering the added benefit of eliminating “short-circuiting” risks. Serpentine Plate Coils are ideal for metal finishing tanks and electroplating baths where precise temperature control is crucial.
Standard Styles and Sizes
Both Multi-Zone and Serpentine double-embossed Coils are available in over 300 standard sizes, with widths ranging from 12 inches to 43 inches and lengths from 23 inches to 143 inches. These standard styles are fabricated in carbon steel or Type 316L stainless steel, making them suitable for a wide range of heating and cooling applications in industrial processes.
Special Designs and Fabrications
Plate Coils offer inherent flexibility, allowing them to be bent, rolled, or otherwise formed into virtually any configuration. In addition to standard materials like carbon steel and stainless steel, Plate Coils can be fabricated from specialty alloys such as Monel, Inconel, Hastelloy, and more. These custom designs can meet unique performance requirements, and surface finishes can be customized to minimize fouling and reduce maintenance.
Manufacturing and Material Options
Construction and Welding
Plate Coils are manufactured by pressing sheet material to form “corrugations” known as embossings. These embossings are seam welded to form double-embossed coils or welded to a flat sheet to create single-embossed coils. The continuous electric resistance welds used in Plate Coil manufacturing ensure consistent and accurate joining, minimizing the risk of errors associated with manual welding. This process is critical for maintaining the structural integrity and performance of the coils in demanding environments like metal finishing and electroplating.
Material Options
Plate Coils are available in a range of materials to suit various industrial applications, including:
- Carbon Steel: Ideal for general-purpose applications.
- 304 and 316 Stainless Steel: Offers excellent corrosion resistance for more demanding environments.
- Specialty Alloys: Includes Monel, Inconel, Hastelloy, Alloy 20Cb-3, 254-SMO, AL6XN, and Titanium, providing options for highly corrosive or extreme environments.
