If the vessel is too large for a screwplug heater, a flanged heater is your best option. They provide efficient heating in larger containers. Positioned towards the bottom of the tanks and using custom element designs, flange heaters ensure even heat distribution.
These heaters have elements extending from the flange, directly submerged in the target medium. A wide range of element materials and coatings are available, so they can withstand almost any environment solution.
