Screw plug immersion heaters are generally used in small to medium size containers at pressures up to 3000 psi and are screwed directly through a threaded opening in the tank wall. Screw plug immersion heaters can usually be designed for most types of liquids with consideration for corrosion and watt density.
Flanged immersion heaters are used in large capacity vessels, in high pressure applications and are installed by bolting the unit to a matching flange welded to the vessel wall. Flanged immersion heaters can usually be designed for most types of liquids with consideration for corrosion and watt density.
Over the Side immersion heaters are used in tanks where through-the-wall heaters cannot be installed, portability is required, or where over the side immersion 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.
Typical application include;
- Heating liquids in a tank
- Heating air and gases
- In-Line heating
- Circulation heating
