Vacuum Furnace Combat Series
Vacuum furnace COMBAT series are used for various purposes such as Quenching, Tempering, Sintering. The product is researched and optimally designed by ULVAC R&D institutes in Japan and is constantly improved and updated with the latest technology. This is the reason why this ULVAC Vacuum Furnace receives high trust from all customers around the world.
Features
- Maximum temperature: 1300 ° C
- Operating temperature: 300 ° C ~ 1250 ° C
- Temperature uniformity: less than ± 5 ° C at 1,150 ° C
- Heating system using graphite rod
- All vacuum pumps, vacuum sensors, vacuum valves, and controllers are manufactured by ULVAC.
- Temperature control by PID integral-derivative algorithm. Combined with IGBT high-power semiconductor valve system
- Heating time from room temperature to 1,250 ° C within 1 hour
- Temperature reduction time from 1,250 ° C to below 150 ° C within 10 minutes
- The tightness of the heating chamber is almost absolute.
- We have available Helium gas leak testing equipment in Vietnam. In order to respond almost immediately when there is a leak problem.
- Especially: ULVAC Vietnam’s team of engineers directly installs and transfers technology to customers.
The latest furnace has just completed installation, testing and handover in early 2023.
