NRA 50/06 IDB for debinding under protective gas | NRA 75/06 as basic version with automatic gas injection and touch panel H 3700 |
These gastight 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
gastight 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:
NRA 150/11 H2 for operation with hydrogen |
Standard Equipment for all models
NR 200/11 H2 for heat treatment under hydrogen |
When hydrogen is used as a process gas, the furnace is additionally equipped with the required safety
technology. Only certified and industry proven safety sensors are used. The furnace is
controlled by a fail-safe PLC control system (S7- 300F/safety controller).
Certain debinding processes under protective gas can also be realized in a chamber or bogie hearth furnace
with inserted gas box as a cost-effective alternative. In our state-of-the-art test center we would be
glad to make tests in order to select the most suitable furnace model.

VHT 8/22-GR with graphite insulation and heating as well as automation package | VHT 40/22-GR with graphite insulation and heating |
The compact furnaces of the VHT product line are available as electrically heated chamber furnaces with graphite,
molybdenum or MoSi heating. A wide variety of heating designs as well as a complete range of accessories provide
for optimal furnace configurations even for sophisticated applications.
The vacuum-tight retort allows heat treatment processes either in protective and reaction gas atmospheres or
in a vacuum, subject to the individual furnace specs to 10-5 mbar. The basic furnace is suited for operation
with nonflammable protective gases or under vacuum.
The H2 version provides for operation under hydrogen or other flammable gases. Key of the specification
up is a certified safety package providing for a safe operation at all times and triggers
an appropriate emergency program in case of failure.
For debinding applications under vacuum, we recommend the VDB version, which besides the
corresponding safety technology has an additional debinding retort in the heating chamber
and prevents the exhaust gases from contaminating the furnace chamber. The exhaust
gases are channelled from the debinding retort into the exhaust gas torch.
The following heating systems are available for the different application temperatures:

Inert gas | √ | √ | √ |
Air | to 400 °C | - | √ |

High vacuum (<10-5 mbar) | - | √ | - |
VHT 40/16MOH2 |
VHT 08/16 MO with hydrogen extension package as automatic version |
In the H2 version the furnaces of the VHT…/MO or VHT…/GR product line can be operated under hydrogen
or other reaction gases. For these applications, the systems are additionally equipped with the
required safety technology. Only certified and industry proven safety sensors are used.
The furnaces are controlled by a fail-safe PLC control system (S7-300F/safety controller).
Certain processes require debinding under protective gases or in vacuum. For these processes the models
VHT…/MO-VDB or VHT…/GR-VDB are perfectly suited. They are equipped with the necessary safety
technology for debinding. The furnace chamber has an additional debinding retort with a direct
discharge into the exhaust gas torch. This system ensures that exhaust gases during debinding
do not get into and contaminate the furnace chamber.

NRA 40/02 CDB | NRA 150/02 CDB |
The chamber ovens NRA 40/02 CDB and NRA 150/02 CDB are specially developed for debinding of
ceramics and metallic powder injection molded parts according to the BASF CATAMOLD®-method.
They are equipped with a gastight retort with inside heating and air circulation. During catalytic debinding,
the polyacetal-containing (POM) binder chemically decomposes in the oven under nitric acid and is
carried out of the oven by a nitrogen carrier gas and burned in an exhaust gas torch. Both
furnaces have a comprehensive safety package to protect the operator and the surrounding.
Model NRA 40/02 CDB is very compact and excels with its excellent cost-performance ratio.
This model is pefectly suited for repeating lab processes and in production. As a professional
production furnace, model NRA 150/02 CDB is also designed for frequent charge changes.
The furnace has an automatic torch control that detects the end of the process measuring the torch temperature.
