Large Vertical High Temperature Vacuum Furnace

The large vertical high temperature vacuum furnace is the kind of heat treatment equipment working in vacuum environment. This metal powder sintering furnace has been extensively applied to ceramic sintering, refractory metal smelting, annealing and university labs. The maximal furnace temperature reaches 2100°C, making our powder metallurgy equipment to be ideal for annealing, drying and heat treatment.

Advantage
1. This high temperature vacuum furnace involves the utilization of resistance heating method, generating no noise. Shimaden programmable controller is employed for ultimate temperature accuracy and promoted electricity efficiency.

2. Vertical layout offers minimal floor space, and shows excellence in terms of lifting, horizontal deployment and feeding.

3. Fully automatic control is realized via intuitive touch screen. PLC provides interlocking function. Furthermore, audile and visual alarms are triggered on overpressure, overheat or too high water temperature, resulting in guaranteed safety.
