Minicoil

Niche Minicoil fluoropolymer heat exchanger

Niche Minicoil Fluoropolymer Heat Exchangers are used primarily in small metal finishing baths where corrosion is often a problem, and in small production tanks and laboratory baths.

The chemically inert, well-known nonstick characteristics of fluoropolymers reduce operating costs by resisting corrosion that causes fouling and scale buildup. The inherently high electrical resistance also helps prevent short circuits and stray currents in the plating baths.

Tubing may be selected in a variety of resins. For electro less nickel applications, Niche offers Q-Series tubing in a protective polypropylene or PTFE frame. For chrome and other plating applications, it offers FEP tubing in a protective CPVC or PTFE frame.

Key Features

  • Reduces operating and maintenance costs
  • No fouling or scaling
  • Tubing in a variety of resins

Slimline Coil

Niche Slimline immersion heat exchanger

These immersion heat exchangers are popular in metal finishing and chemical processing applications, and are especially suited to batch and continuous steel pickling applications. Unlike some immersion coils made of sub-quality FPI, Niche fluoropolymer tubing virtually eliminates corrosion and fouling, which reduces operating costs through reliable, maintenance-free operation and long service life.

Slimline heat exchangers are available in a choice of two tubing materials: standard FEP and proprietary “Q” resin that extends pressure and temperature performance.

The Q-Series Slimline coils are preferred for efficiency by avoiding desuperheating in steam heat applications. In metal processing, high-efficiency Niche Slimline Coil™ Heat Exchangers also save energy, reduce waste, and cut processing costs by minimizing acid consumption and spent pickle liquor disposal.

Key Features

  • Reduces operating and maintenance costs
  • No fouling or scaling
  • Energy efficient by avoiding desuperheating
  • U-shape or straight configurations
  • Lengths from 4 to 16 feet

Supercoil

Niche Supercoil immersion heat exchanger

Volume metal finishing operations use Niche Supercoil Heat Exchangers for high-efficiency heating and cooling. The well-known non-stick characteristics of fluoropolymer resins resist scale buildup. Its inherently inert character prevents corrosion and fouling. Its high electrical resistance minimizes the effects of stray currents in electroplating tanks. Immersion heat exchangers made with other materials have hidden costs in the form of maintenance and reduced heating efficiency caused by scale buildup.

Supercoils are available in FEP as well as in proprietary Q-Series tubing formulations. Q-Series coils are made using a special fluorocarbon compound that significantly improves thermal efficiency and increases temperature and pressure capabilities. Q-Series Supercoils are ideal for most metal finishing operations, particularly those involving electro less nickel and copper plating. They provide twice the heat transfer rate, which allows the overall length of the Supercoil to be decreased to fit smaller finishing tanks.

Applications include electroplating, electroforming and electro less plating baths, acidic and alkaline solutions for etching, chemical milling, anodizing, cleaning, stripping, electro polishing and similar operations.

Key Features

  • Reduces operating and maintenance costs
  • No fouling or scaling
  • Tubing in a variety of resins to match different plating solutions
  • Efficient heating and cooling
