  • Element diameters: 0.315”, 0.375”, 0.430”, 0.475”
  • Sheath materials: Stainless steel, Incoloy®, Steel
  • Custom sizes and wattages available

Benefits
  • Lightweight and portable
  • Easy installation and maintenance
  • Moisture, oxidation, and corrosion resistant
  • Durable and safe design

Applications
  • Water heating
  • Freeze protection
  • Viscous oils and storage tanks
  • Degreasing tanks, solvents, salts, paraffin, caustic solutions

Installation Guidelines
  • Ensure heating element is fully immersed to prevent failure
  • Consider solution volume reduction due to evaporation or removal

Selection Guide
Choose the appropriate heater based on application, sheath material, and flange material. For corrosive environments, Inconel or Titanium sheaths are recommended.

Technical Specifications
Tables provide detailed specifications for single and three-element heaters, including KW, sheath material, and standard voltages. Special dimensions and configurations are available upon request.

Additional Features
  • Custom wattage and voltage options
  • Built-in thermostats and high limit controls
  • Explosion-proof terminal boxes

Pipe-Insert Immersion Heaters
Designed for heating viscous fluids in large tanks, these heaters feature alloy-sheathed elements and moisture-resistant terminal boxes. They are suitable for applications like asphalt, molasses, tar, and paint.

Heating Process
The heating element transfers heat to the pipe's inner wall through convection and radiation. It is crucial not to fill the pipe with a heat transfer fluid.

Selection and Sizing
  • Determine kilowatts needed to maintain tank temperature
  • Select heaters with appropriate insert length for heat transfer
  • Use single or double element heaters for balanced three-phase systems
