Applications

The large variation in heating element material and shapes of over-the-side immersion heat- ers offers a wide selection in the application of these units. Water, oils, solvents, plating baths, salts and acids are some of the many liquids and viscous materials commonly heated with immersion heaters. Over-the-side types permit portability, easy removal for cleaning of tanks and heaters and ample work- ing area within the tank when installed.

Important — When selecting a tank heater design, the user should make sure the sheath material is suitable for the solution being heated at the maximum temperature expected, with proper safety factor.

Sheath Material — Selection Guidelines1
Material Being Heated	Typical Sheath Material
Clean Water (pH6 to pH8)	Copper
Demineralized or De-ionized Water	Stainless Steel (passivated)
	INCOLOY®
	Fluoropolymer
Medium Weight Oil, Alkaline Cleaning (low concentration)	Steel
Mild Soaking Cleaners
Mild to Medium Corrosive Solutions, Many Oxidizing	Stainless Steel
Acids, Organic Chemicals, Mild Aqueous Solutions	INCOLOY®
Chromic Acid (10%), Nitric Acid (to 65%)	Titanium
Salt Brine, Many Plating Solutions (i.e. Nickel, Silver,
Zinc, Gold)
Soft Metal Melting	Cast Iron
Molten Metal, High Corrosive	Ceramic
Most Acids, Plating Solutions, Pickling Solutions	Fluoropolymer
	Quartz2
