Immersion Specialty Heaters | Precision Thermal Solutions
Immersion specialty heaters provide maximum thermal efficiency by delivering heat directly into liquids. These high-performance tools are engineered for challenging industrial environments, including corrosive chemical baths, high-viscosity oils, and precision laboratory settings. Unlike external wraps, immersion elements eliminate ambient heat loss, making them nearly 100% efficient.

Common configurations include Screw-Plug models for pressurized tanks, Over-the-Side heaters for open vats, and Bung-Hole heaters designed specifically for 55-gallon drums. Constructed from 304 stainless steel, Incoloy, or Titanium, these heaters ensure long-term durability and precise temperature maintenance for critical industrial processes.
Immersion specialty heaters are designed for direct contact heating of liquids in tanks, drums, and industrial vessels. These heaters are engineered to handle specific chemical environments, high-temperature requirements, and unique container geometries. By placing the heating element directly in the medium, they provide nearly 100% thermal efficiency.

Key Types of Immersion Heaters Bung-Hole Heaters: Specifically designed to fit through the standard 2-inch NPT bung of a 55-gallon drum. These are ideal for rapid warming of oils, wax, and non-corrosive liquids.

Over-the-Side Heaters: These portable units hang over the edge of a tank, making them perfect for applications where through-the-wall installation is not possible.

L-Shaped Heaters: Designed to sit at the bottom of a tank to provide uniform bottom-up heating, ensuring the entire volume of liquid reaches the target temperature.

Screw-Plug Heaters: Threaded directly into a tank wall, these are common in water heating, chemical processing, and freeze protection for large reservoirs.

Specialty Immersion Heater Overview

This industrial-grade immersion heater is designed for direct liquid contact, providing rapid heat-up times and high thermal efficiency.



  • Material: 304 Stainless Steel (corrosion resistant)
  • Voltage: 120V / 1500W
  • Safety: Built-in adjustable thermostat and grounded element


Ideal for warming oils, lubricants, and chemical solutions in standard 55-gallon drums.

Safety & Maintenance Liquid Levels: Never operate an immersion heater unless the heating element is fully submerged. Operating in "open air" will cause the element to burn out instantly.

Material Compatibility: Ensure the sheath material (Stainless Steel, Titanium, or Incoloy) is compatible with the chemical properties of the liquid being heated.

Sediment Control: Periodically clean the element to prevent scale buildup, which can act as an insulator and lead to premature failure.
