Tunnel ovens for thermal treatment

Tunnel ovens for thermal treatment

Continuing in its mission to enrich its range of products through a constant research and development activity, Angelantoni Industrie has increased its contribution in the Renewable Energies sector with the production of tunnel ovens for the annealing treatment and coating of receiver tubes for thermodynamic solar plants.

For this purpose, equipment for performing temperature tests up to 650°C and programmable heating/cooling ramps  on specimens was created first. This made it possible to identify the best thermal cycle to use for the tubes in the tunnel oven treatment cycle, in order to guarantee their best performance and reliability. On the basis of the data collected, two types of tunnel ovens were then developed:

• "GMS” for the treatment of the glass/metal solder
• "AR” for anti-reflective coating treatment
