Front made of textured stainless steel

Retort furnace SRA 200/09

The retort furnaces SR and SRA (with gas circulation) are designed for operation with non-flammable or flammable protective or reaction gases. The furnace is loaded from above by crane or other lifting equipment provided by the customer. In this way, even large charge weights can be loaded into the furnace chamber.

Depending on the temperature range in which the furnace be used, the following models are available:

Models SR .../11 with Tmax 1100 °C

  • Heating from all sides outside the retort
  • Temperature uniformity up to +/- 5 °C inside the work space
  • Retort made of 1.4841
  • Top down multi-zone control of the furnace heating

Models SRA ../09 with Tmax 950 °C

  • Design like models SR…/11 with following differences:
    • Atmosphere circulation with powerful fan in the furnace lid provides for temperature uniformity of up to +/- 5 °C inside the work space

Models SRA ../06 with Tmax 600 °C

  • Design like models SRA…/09 with following differences: see page 71
    • Heating inside the retort
    • Temperature uniformity up to +/- 5 °C inside the work space
    • Single-zone control
    • Retort made of 1.4841

Standard Equipment (all models)

  • Design like standard equipment of models NR and NRA with following differences:
    • Charging from above with crane or other lifting equipment from customer
    • Hinged lid with opening to the side
    • Defined application within the constraints of the operating instructions
    • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Additional equipment, H2 version or IDB version see models NR and NRA
