Electric Immersion Heater with Temperature Control

The flanged immersion heater is a primary type of electric heater used for higher kilowatt applications. It effectively heats liquids and gases inside of tanks and pressure vessels. Flanged heaters, including those in boilers, are rated for 2000 kilowatts or more.

Commonly used flanged heaters often heat water and oil. Depending upon the application, models vary by kilowatt rating, terminal type and sheaths. Precise temperature controls and monitoring features are available.

Heaters for Water Applications

These types of heaters may be referred to as through-the-side or over-the-side models. These heaters are often designed for over-the-side use. They also heat oils, solvents, and acids evenly and effectively.

Over-the-side replacements are easily done since there is no tank penetration during installation. Hi-Watt has superior heaters for water applications with the best sheath and heating element construction. Find desired kilowatt ratings, terminal enclosures and mounting methods today.

Benefits of Immersion Heaters

Heating a liquid by applying a flame or electric burner to its container is generally inefficient and inconsistent. These heaters are submerged in gases or liquids, contacting the target substance directly. Some of the many advantages of immersion heating devices include:

  • Rapid heat transfer to the target solution
  • Safe, non-combustible operation
  • Efficient heating through convection and conduction
  • Easy powering off and on
  • Minimal maintenance requirements
  • Easy addition of thermostatic sensors and controls

Whether you are looking for ease of installation, higher kilowatt capacity or economic options, Hi-Watt offers a versatile range of heater designs and configurations. Our screw plug, flanged and over-the-side styles have you covered for any size, watt density, input power or connection style your specifications require.
