Bell and Pit Type Furnaces

Sistem Teknik design and manufacture Pit and Bell type furnaces with his own technology for heat treatment of coils of strip, wire and rods in big size loads.
Customer requirements fort he process reasults are;

  • No oxidation
  • No decarburization
  • Excellent mechanical results
  • Short cylcle time
  • Low energy consumption

The process can be performed under nitrogen, but with hydrogen the technical and commercial results are even beter due to the outstanding physical properties of hydrogen.
