Laboratory Furnaces
High Temperature Laboratory Furnaces LHTG/LHTM/LHTW
up to
2200°C (3000°C)
Series LHTG / LHTM / LHTW furnaces are typical laboratory furnaces
designed for all types of heat treatment processes. They are used
for high vacuum applications up to 1x10-6 mbar and very pure atmospheres
of hydrogen.
The versions made of graphite are standard rated for 2200°C,
but can also be supplied for temperatures up to max. 3000°C.
The furnaces are available with manual operation as standard.
Fully automatic control with SIEMENS PLC and WINCC visualisation
is available at option.
- High purity process space (LHTM and LHTW)
- Particularly robust
and durable design of heating system
and insulation (LHTG) - Pressure control between 10 – 1000 mbar for each process gas
- Smooth controlled evacuation appropriate for powders
- Charging racks for the highest temperatures made of metal
- TÜV-proven safety management for flammable and poison gases
- Full automatic operation also for highly complex processes
- Data recording for quality management
