What are Immersion Coils and what are they used for

Category: Business

Immersion coils are ideally suited for almost all metal finishing (plating) and metal processing (pickling) applications. The fluoropolymer tubes (FEP, PFA, and Q) is/are non-conductive, chemically inert, flexible, and tough. Most of the competition is not suited for, hot, strong sulfuric acid or fluoride-containing baths. In these applications, Niche immersion coils should be a clear choice. In addition, a few ppm of corroded metal can ruin many baths. Niche immersion coils should have an advantage wherever bath contamination is critical. Advantages for Niche Immersion coils (Supercoils) in plating operations : Electrically non-conductive- to prevent stray currents and short circuits. “Non-stick” surface provides excellent fouling resistance. The chemical inertness of fluoropolymer prevents stray ions caused by coil corrosion from entering the bath and upsetting the bath and current control. Flexibility, toughness, and corrosion resistance result in minimal maintenance and replacement cost. Immersion coils are lightweight and narrow, permitting easy installation and removal. If repairs are required, they can be done by the customer, at his plant, without any special procedures or tools. They are resistant to thermal shock, although some change-over time is required between heating and cooling cycles.
