Cooling Tower Heaters

Check up to five results to perform an action.

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 in 3/4" NPT (Series HX-761) or 1-1/4" NPT (Series HX-762).

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 are furnished on all heaters. Located on five foot centers to keep the element in place even in high water velocities, these legs are adjustable for heights between 2" and 3-1/2".

Liquid proof/Explosion-Resistant Outlet Boxes are furnished on all heaters.
