Tank and Basin Heaters
Pipe Insert Heaters
Open Coil Pipe Insert Heaters are designed to insert into a horizontal 3” pipe mounted just above the anticipated sludge level in the tank and below the expected minimum operational fluid level. These units provide a low watt density over a large surface area and are used to heat sensitive fluids. Advantages include the ability to change the heater without draining the tank and to provide up to a Schedule 80 pipe wall in mildly corrosive fluids.
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
Cooling Tower Heaters
Cooling Tower Heaters are long cartridge heaters designed with a conservative 25 W/Sq. In. maximum watt density. These units provide a long “gentle” heat covering a majority of the tank or vessel. They are used primarily in below grade concrete sumps, for cooling towers or to heat viscous fluids. The heaters can be specified with through-the-wall or over-the-side construction.
Over-the-Side Heaters eliminate the need for cutting a hole in the basin. Internal wiring runs from the horizontal heater elements through a vertical riser and extension arm with an outlet box located over the side of the basin.
Adjustable Sludge Legs and Liquidproof/Explosion-Resistant Outlet Boxes are furnished on all heaters.
