Why Choose Kerone Tubular Heaters
Tubular heating elements of Kerone are the most versatile and the best suited solutions to a large number of applications. Kerone’s tubular elements are factory-configured to almost any shape or size. Custom bending diameters can be made upon request. Typically using steel, stainless steel, Incoloy, inconel or titanium alloys, tubular elements are often regarded as the foundation of all heating elements. These heating elements have a strong outer sheath to help protect the heater from physical stress and uses high quality alloys to allow efficient heat transfer from resistance coil to your heating medium Depending on their rating, sheath and shape, tubular elements are used in a variety of heat applications (conduction, convection, radiation heating) that require process temperatures of up to 750°C (1382°F) to heat liquids, gases and solids. A variety of diameters are available to help adjust watt densities in your application to design these electric heaters for best performance and long life. Standard and custom made terminal pins allow for easy installation and maintenance. Kerone uses high quality magnesium oxide to allow for efficient heat transfer from resistive coil to your heating medium whether it is air, liquid or solid. Bending radiuses are designed with careful expertise to allow for optimal performance within your application.

Frequently Asked Questions (FAQ)
Kerone offers tubular heaters with sheaths in stainless steel 304 and 316, Incoloy 800 and 840, copper, brass, titanium, and Inconel alloys, selected based on the specific temperature, corrosion, and compatibility requirements of the application.
Maximum operating temperature depends on the sheath material. Stainless steel sheaths are rated to approximately 750°C, Incoloy to 900°C, and Inconel to over 1100°C for air heating applications.
Yes, Kerone manufactures tubular heaters in custom bent configurations to suit specific installation geometries. A wide range of bending options including U-bends, coils, and complex 3D profiles are available.
For liquid immersion applications, the active (heated) length of the tubular heater must be fully submerged below the liquid surface to prevent overheating of the sheath. Kerone recommends a minimum of 50mm of submersion beyond the active length.
Watt density is the power output per unit of active surface area (W/cm²). It determines the operating temperature of the sheath and influences the heater's suitability for different applications. Lower watt densities are used for high-viscosity or sensitive fluids, while higher watt densities are appropriate for water or air heating.
Yes, Kerone can supply tubular heaters with integral thermocouples or thermostat sensors built into the element for direct temperature measurement and control at the heater surface.
Screw plug heaters thread directly into a tank fitting, while flange mounted heaters bolt onto a matching flange on the vessel wall. Flange types suit larger heaters or applications needing a more robust seal.
The same basic element can be configured either way, but the terminal head, mounting style, and watt density are chosen differently depending on whether the heater sits in moving air or submerged liquid.
The terminal end uses ceramic insulation and sealing compounds to keep moisture out of the connection point, with additional protection available for heaters used in wet or washdown environments.
Standard straight terminal heads and right angle terminal heads are both available, letting you choose the connection direction that best fits your duct or chamber layout.
Sizing depends on the airflow rate, the temperature rise needed, and the available surface area for the element, and Kerone calculates this based on your duct dimensions and process conditions.
Yes, Kerone can supply tubular heaters with terminals at one end only or at both ends, depending on your wiring access and how the element needs to be supported.
Long elements often need intermediate supports to stop sagging under their own weight at high temperature, and Kerone can advise on bracket spacing based on the element length and orientation.
Yes, with the right sheath material such as titanium or Incoloy, tubular heaters can handle many corrosive fluids. Kerone matches the sheath to your specific fluid chemistry.
A properly bent element retains its rated output, since Kerone controls the bending process to avoid thinning the sheath or disturbing the internal coil. Poor quality bending elsewhere in the market is what typically causes early failure.
Kerone’s custom-designed heating and processing solutions are built to meet the demands of your growing operations. Whether you’re upgrading equipment, expanding production, or need a tailor-made solution
