These gas tight retort furnaces are equipped with direct or indirect heating depending on temperature. They are perfectly suited for various heat treatment processes requiring a defined protective or a reaction gas atmosphere. These compact models can also be laid out for heat treatment under vacuum up to 600 °C. The furnace chamber consists of a gas tight retort with water cooling around the door to protect the special sealing. Equipped with the corresponding safety technology, retort furnaces are also suitable for applications under reaction gases, such as hydrogen or, in combination with the IDB package, for inert debinding or for pyrolysis processes.

 

Different model versions are available depending on the temperature range required for the process:

 

Models NRA ../06 with Tmax 650 °C

Heating elements located inside the retort

Temperature uniformity up to +/- 5 °C inside the worke space

Retort made of 1.4571

Gas circulation fan in the back of the retort provides for optimal temperature uniformity

Models NRA ../09 with Tmax 950 °C

Outside heating with heating elements around the retort

Temperature uniformity up to +/- 5 °C inside the worke space

Retort made of 1.4841

Fan in the back of the retort provides for optimal temperature uniformity

Models NR ../11 with Tmax 1100 °C

Outside heating with heating elements around the retort

Temperature uniformity up to +/- 5 °C inside the worke space

Retort made of 1.4841
