For double boiler heaters, Screw Plug or Flanged Immersion Heaters are commonly used in electroless nickel plating process.
A double boiler is a dip processing tank inside the heating tank. Used in special processing where the chemistry of the dip tank must be controlled.
The chemical process of Electroless Nickel Plating can use double boilers. The outer tank is usually filled with inhibited ethylene glycol or a heat transfer oil. We can help you reduce your costs and get the lowest BTU per square inch.
De-rated immersion heaters are 15-20 watts per square inch, usually designed with an electro polished sheath. The 15-20 WSI on the sheath material results in a 3 WSI in the double boiler tank. Because all of the surface area is being used to heat the chemistry, the tank is very effective.
