SAH 1780/60S SAH 1000/85  

Motor-driven fresh-air and exhaust air flaps


2 x SAH 5600/75 S in production

SAH 200/60 - SAH 1000/85

Due to their robust design, these pit-type furnaces with air circulation are particularly useful for a professional heat treatment demanding optimum temperature uniformity. Production processes such as tempering, solution annealing, artificial ageing, and soft annealing can be realized with these pit-type furnaces.

  • Tmax 600  °C or 850  °C
  • Useful for heavy charge weights
  • Air circulation fans in the furnace lid, high circulation rate
  • Heating chamber with air baffle cylinder
  • Heating elements on all wall surfaces
  • Distribution of air flow through grid at the furnace bottom
  • Pneumatic or hydraulic lid lifting device
  • Temperature uniformity up to +/- 3 °C according to DIN 17052-1
  • Defined application within the constraints of the operating instructions

Additional equipment

  • Integral fan for fast cooling
  • Optimization of the temperature uniformity up to +/- 2 °C according to DIN 17052-1
  • Variable rpm converter control of the air circulation velocity for sensitive parts
  • Multiple zone control or special air circulation system for optimum temperature uniformity tailored to the charge
  • Charge weights up to 7 tons
  • Process control and documentation with Controltherm MV software package
