Over-The Side Heaters

Understanding Over-the-Side Heaters

An over-the-side immersion heater hangs over the rim of an open tank with its heating element down in the liquid. They are used for freeze protection, water heating, and keeping wax or other viscous fluids workable.

We don't sell over-the-side or other immersion heaters. To heat or freeze-protect a container from the outside, we carry Powerblanket heaters: insulated drum heaters, IBC tote heaters, steel IBC tank heaters from 250 to 550 gallons, and bucket heaters. For Peabody ProChem poly tanks, Peabody makes flexible tank heating blankets sized by tank diameter.

Compare the range in Tank Heating & Temperature Control.

Heater Blankets vs. Over-the-Side Heaters

• Nothing in the liquid: A blanket heats through the container wall, so no element touches the product and nothing has to fit through the opening.
• Insulated: Powerblanket heaters are insulated, which keeps heat in the container in cold weather.
• Set temperatures: Lite drum heaters hold a fixed 145°F, and the steel IBC tank heaters have a maximum of 145°F.
• Hazardous areas: Class I Division 2 drum and tote heaters are available for classified locations.

Over-the Side Heaters Applications

Many jobs an immersion heater does, a heater blanket can do from the outside:

• Freeze Protection
  Drum, tote and steel IBC heaters keep water and water-based liquids from freezing in storage.
• Viscous Material Maintenance
  Heat keeps oils, coatings and other thick fluids flowing for pumping and pouring; the 5-gallon wax melting blanket holds a fixed 185°F.
• Diesel Exhaust Fluid
  The 330-gallon DEF tote heater keeps diesel exhaust fluid (DEF) usable through the winter.
