VHT 8/22-GR | VHT 40/22-GR |
The compact furnaces of the VHT line are available as electrically heated chamber furnaces with graphite,
molybdenum or MoSi2 heating. A wide variety of heating designs as well as a complete range of accessories
allow optimal furnace configuration for technically demanding customer processes. The vacuum-tight retort
enables heat treatment processes either in protective and reaction gas atmospheres or in a vacuum,
depending on the application, all the way to 10-5 mbar. With the appropriate safety technology,
the furnaces are also suitable for operation with hydrogen.
Heating Concepts
The use of automatic valves for process gas or exhaust air management and the powerful H3700
controller allow the entire heat treatment process to be run fully automatically. The entry of all
process data (temperatures, ramps, gas supply and vacuum) is easily controllable from a large,
12" graphic control panel. System status with all process-related data are clearly shown on a
process control diagram. All valves and the vacuum pump can also be operated manually from
here as well. The system has an automatic pre-program and post-program for purging the
furnace chamber and also features automated leak testing.
When hydrogen is used as a process gas, our systems come equipped with additional safety technology.
Only certified and industry proven safety sensors are used. The furnaces are always controlled using a
fail-safe controller (S7-300F/safety controller). The controller and documentation are carried
out using Nabertherm Control Center NCC (see page 42).
