Over-the-Side Heaters
Over-the-side heaters are ideal for heating water, oils, solvents, salts and acids. Over-the-side heater application versatility is enhanced with optional sheath materials, kilowatt ratings, terminal enclosures and mounting methods.
The L and O shaped “installed-from-the-top” heaters slide easily into tanks, with the heated portion immersed along the side or at the bottom. The drum immersion heaters are designed for direct immersion in a standard 55 gallon steel drum. Watlow® vertical loop immersion heaters are well-suited for open tank applications.
