Salt-Bath Furnaces for Heat Treatment of Steel or Light Metals Electrically Heated or Gas-Fired
 TS 40/30, electrically heated TSB 30/30, gas-fired

TS 30/18 with preheating chamber above the salt bath and crane to immerge the charge

TS 20/15 - TSB 90/80

Salt-bath furnaces offer remarkably high temperature uniformity and excellent heat transfer to the work piece. Our salt-bath furnaces TS 20/15 - TSB 90/80 are especially useful for heat-treating of metals in neutral or active salt baths. Processes such as carbonitriding (e.g. Tenifer) up to 600 °C, carburizing up to 950 °C, or bright annealing up to 1000 °C can be realized. In their standard version these furnaces are equipped with safety technology for heat treatment of steel. As addional feature they can be equipped with extended safety technology for heat treatment of light metals.

  • Tmax 750  °C or 1000  °C in the salt bath
  • Safety technology according to EN 60519-2
  • Useful for heat treatment of steel
  • Salt bath temperature control
  • Electric (TS) all-round heating or gas heating (TSB)
  • Removable collar plate made of solid steel
  • Insulated swing-a-way lid
  • Temperature uniformity up to +/- 2 °C according to DIN 17052-1 in the salt bath
  • Over-temperature limiter with manual reset in the furnace chamber to prevent dangerous conditions for the furnace or personnel
  • Salt bath control of salt bath and furnace chamber
  • Defined application within the constraints of the operating instructions


  • Type P: low carbon steel and CrNi plated for carburizing baths up to 950  °C, neutral salt and annealing baths up to 850  °C
  • Type C: high alloy CrNi steel for neutral salt and annealing baths up to 1000  °C and for dip brazing of Aluminium

Additional equipment

  • Exhaust gas collection at rim for connection to an exhaust system
  • Enhanced safety systems for heat treatment of aluminium and magnesium in the salt bath with second over-temperature limiter with manual reset controller and PLC-bath control with thermocouples in the salt bath and in the furnace chamber
