PRODUCT PARAMETERS
Description
1100°C Vacuum Distillation Furnace
This 1100°C vacuum distillation furnace features a quartz furnace tube, dual heating zones with independent temperature control, and a vacuum system equipped with a molecular pump. It offers a maximum operating temperature of 1100°C and a vacuum level better than 6.0×10⁻⁴ Pa. The unit is operated via a 7-inch touchscreen and supports 50-segment programmable temperature control. It is designed for use in industrial production environments to perform the melting, evaporative distillation, separation, and purification of materials—such as gold, silver, copper, and other precious or rare metals, as well as their alloys—under high-vacuum or protective-atmosphere conditions.
Product Features
- Horizontal Quartz Tube Structure with Sliding Mechanism
The system utilizes a horizontal quartz tube configuration (150 mm in diameter, 1400 mm in length, and 5 mm in wall thickness). One end features a sealed flange equipped with a vacuum port and a gas inlet valve, while the other end is capped with an elliptical head. The quartz tube is designed to slide horizontally, facilitating material loading/unloading and maintenance of the furnace tube. The heating zone has an internal diameter of 170 mm.
- Dual-Zone Independent Temperature Control with 50-Step Programming
The furnace features two heating zones with independent temperature control, achieving an accuracy of ±1°C. It supports a maximum operating temperature of 1100°C (with a long-term operating temperature of ≤1100°C). K-type thermocouples are used for temperature measurement (range: 0–1250°C), with a maximum heating rate of 15°C/min (non-linear).
- High-Vacuum Molecular Pump System (Vacuum Level < 6.0 × 10⁻⁴ Pa)
Equipped with a molecular pump system—capable of supporting up to three units—the setup achieves a vacuum level of less than 6.0 × 10⁻⁴ Pa. This high-vacuum environment effectively lowers the boiling points of materials, making it ideal for the vacuum distillation and purification of metals and compounds with high boiling points.
- All-Around Heating via High-Temperature Alloy Resistance Wires
The heating elements consist of high-temperature alloy resistance wires (containing molybdenum, with a surface temperature rating of 1450°C) sourced from Beijing Shougang. These are arranged around the furnace tube to create a uniform heating field. Combined with 1700-grade high-temperature alumina fiber insulation, the system offers excellent thermal retention, keeping the furnace exterior temperature at ≤45°C.
- Compact Design Optimized for Production Line Integration
With dimensions of approximately 5500 mm (width) × 1000 mm (depth) × 1500 mm (height), the elongated, linear structure is well-suited for integration into production lines, allowing for seamless connection with upstream and downstream equipment.
