Applications
The large variation in heating element material
and shapes of over-the-side immersion heaters 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 working 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.
