Product Features (Vacuum Furnace)
- Quartz Glass Inner Liner, High-Purity Furnace Chamber
This vacuum atmosphere furnace is equipped with a quartz glass inner liner, ensuring high furnace chamber cleanliness, high temperature resistance, corrosion resistance, and preventing sample contamination. It is particularly suitable for experiments and production processes with stringent requirements for furnace chamber cleanliness.
- Mechanical Lifting Top Cover, Convenient Operation
The sealed top cover of the vacuum atmosphere furnace is designed with a mechanical lifting mechanism, allowing for easy lifting of the sealed top cover. Once lifted, the entire top cover can rotate, saving manpower and time, and facilitating furnace tube cleaning, sample loading and unloading, and routine maintenance.
- Water Circulation Cooling System, Energy Saving and Environmentally Friendly
To conserve resources, the furnace is equipped with an imported hot water circulation pump and circulating water tank. The imported hot water circulation pump can withstand hot water temperatures up to 160℃ and can operate continuously for over one year. Water cooling is provided for the furnace inlet, furnace door, and furnace top within the furnace chamber. Multi-channel pure aluminum water circulation heat sinks significantly reduce the risk of overheating.
- Vacuum System and Pressure Control
A water-circulating vacuum pump unit is used, with a vacuum value of -0.1MPa. The furnace lining steel plate is 6-20mm thick, double-sided welded, and can withstand a positive pressure of 0.1MPa. It is equipped with dual-indicator pressure gauges for both positive and negative pressure, and a digital vacuum gauge is optional, enabling precise control of the vacuum pressure.
