Heat Exchangers Ametek, Chemical Products Div. Wilmington, Del.

Ametek Supercoil Heat Exchangers are designed for heating and cooling in a wide range of metal-finishing applications. The heat exchangers come in lengths from 3 to 16 ft with 100 to 280 tubes of FEP or Q-Series resins. Well-known, nonstick characteristics of Teflon resist corrosion and fouling; high electrical resistance minimizes effects of stray electrical currents in plating tanks. The heat exchangers are available with heat trans- fer areas ranging from 6.5 to 113 ft2. These high- efficiency immersion coils are ideal for electroplating, electroforming, and electroless plating baths; and acidic and alkaline solutions for etching, chemical milling, anodizing, cleaning, stripping, and electropolishing op- erations.
