OVER-THE-SIDE IMMERSION HEATER
The over the side immersion heater offers a wide variety of styles and shapes to meet nearly all needs. Whether you are heating a small pail of water or a large tank of caustic, we have the right product for the job. If standard designs do not match the application, we offer fast delivery on most custom designs. Since direct immersion is 100% efficient and over the side immersion heaters require no tank modification these are the most easily used yet among the most effective means to heat your process. Used in tanks where through-the-wall heaters cannot be installed, portability is required, or where heaters must be removed for cleaning without emptying the tank. Suitable for freeze protection, for heating viscous materials to improve flow, or most open tank applications with proper sheath and watt density selection.
Watt Density Per Application
- 90 Watts Per Square Inch – For heating clean water only in commercial and/or residential applications. Element life is sacrificed in favor of a low initial heater cost.
- 60 and 45 Watts Per Square Inch – Industrial water heating – many aqueous solutions which are compatible with steel and Incoloy.
- 23 and 20 Watts Per Square Inch – For heat transfer oil, cleaners, high temperature air and gas heating.
- 15 and 12 Watts Per Square Inch For lubricating oils, medium viscosity oils, high temperature air and gas heating.
- 8 and 6 Watts Per Square Inch – For #5 and #6 fuel oil heating, viscous materials, raw crude oil, residual oils, high temperature air and gas heating.
