Radiant Tube Furnace

Radiant tube furnace or simply tube furnace are versatile furnace known for their productivity and low maintenance. These furnace are either gas fired or electricity fired and posses many features that are essential for the industrial heating. Tube furnace are designed to handle both light or heavy work loads. The furnace can be supplied for air atmosphere or endothermic, exothermic, or nitrogen atmospheres.

Features
Following are the features of tube furnace:

• Lading is easy
• Excess temperature instrument
• Protection from overheating
• Available for various atmospheres
• Well insulated
• In some tube furnace emergency nitrogen gas purge circuit activates on power failure or loss of atmosphere
• Heat is distributed across the periphery of the furnace uniformly.
• Fan mounted on roof circulates the atmosphere over the radiant tubes and through the workload.
• The fan and the fresh incoming atmosphere is blended to assure mixing and uniform atmosphere.
• Ceramic insulation minimizes the consumption energy and boost the productivity and efficiency with faster thermal cycling and reduced heat loss

Applications
The applications of radiant tube furnace are as follows:

• Hardening
• Normalizing
• Carbonitriding
• Brazing
• Annealing
• Carburizing
