Ceramic radiant tube heater

Features

In short: Volton ceramic radiant tube heaters are custom-built for industrial heating applications. They can operate at temperatures up to 1400 °C (2552 °F) and can be configured to meet specific installation, dimensional and electrical requirements.

Configuration and installation

• Can be installed horizontally or vertically in different types of industrial furnaces.
• Can be installed in open air or inside radiant tubes when operating in corrosive environments.

Temperatures and materials

• Maximum operating temperature of up to 1400 °C (2552 °F).
• Radiant heating rods available in nickel-chrome 80/20 or Kanthal A-1, with lengths up to 12 ft.
• Ceramic element outside diameters ranging from 3 to 9 in.

Electrical specifications

• Low-voltage operation available up to 600 V, three-phase.
• Lower voltage allows the use of a larger resistance wire, resulting in higher current.
• CSA and UL certifications.

What is a ceramic radiant tube used for?

Ceramic radiant tubes are used in industrial processes that require high-temperature heating and heat transfer without direct contact with the material being heated. They are commonly used in furnaces and various types of heat-treatment equipment.

How does radiant heating work?

Radiant heating transfers part of its thermal energy as radiation toward the surfaces being heated. Unlike systems that rely primarily on circulating air, radiant heating transfers heat directly toward materials or components exposed to the heat source.

What should you consider when choosing a radiant tube?

Selecting a radiant tube depends on the operating conditions of the installation. Required temperature, available dimensions, electrical supply, furnace type and operating environment are among the main factors to consider.

• Required operating temperature
• Available dimensions and installation space
• Voltage and electrical supply
• Type of furnace or equipment
• Installation orientation
• Process operating conditions

Element temperature vs. process temperature: what is the difference?

The maximum temperature of a heating element does not necessarily represent the actual temperature of the furnace, component or process. The resulting temperature also depends on power, system configuration, heat losses and operating conditions.

Applications

Volton ceramic radiant tube heaters and bayonet heating elements are suitable for industrial processes that require powerful, uniform and precise heating.

• Heat treatment in industrial furnaces
• Metal quenching
• Tempering furnaces
• Annealing and re-annealing
