Deep Tank Heaters
Deep Tank Heaters are designed to fit into a manhole of an enclosed tank or double wall tank installed either above or below grade. Often the riser is “split” to facilitate installation. Watt densities can vary from 50 W/Sq. In. for water applications to 5 W/Sq. In. for heavy fuel oils. Controls are often provided to avoid penetrating the tank elsewhere. The element bundle diameter can range from a 12″ O.D. to a maximum of 22″ O.D.
