FHH series are used for various purposes such as quenching, tempering, sintering and brazing of various metals. Chamber configuration can be multiplied up to 3 chambers by adopting fork carry system.





  • Maximum temperature1350ºC,Operation temperature800 to 1150ºC
  • Temperature uniformity is within ± 5ºC at 1150ºC
  • Keeping the heating chamber in vacuum for high quality and repeatability of products.
  • Carrier gas system is implemented to minimize metal evaporation.
  • At cooling process, heating chamber is not cooled so that power consumption can be saved.
  • The heating chamber is kept in vacuum to prevent from oxidizing so that lifetime for internal parts of the heating chamber can be longer.
  • Water-cooling jacket construction contributes clean work environment.


  • Quenching, Tempering : Various machine parts, Dies.
  • Sintering : Superhard tools, Magnet.
  • Brazing : Heat exchanger, machine parts.
