Vacuum Atmosphere Hybrid Box/Tube Furnace for Precision Heat Treatment

ZYLAB Vacuum Atmosphere Hybrid Box/Tube Furnace

Introduction:

The ZYLAB Vacuum Atmosphere Hybrid Box/Tube Furnace is an advanced high-temperature heat treatment system that integrates both box furnace and tube furnace functionalities. Designed for precise thermal processing under vacuum or controlled atmosphere conditions, this hybrid furnace is ideal for applications requiring high purity environments and uniform heating.

Equipped with a water-cooled flange system to reduce flange and seal temperatures, it ensures excellent vacuum integrity and system safety. This hybrid design makes it suitable for sintering, annealing, quenching, brazing, and crystal growth in scientific research and small-scale production.

Key Features & Advantages:

1. High-Precision Temperature Control

• PID intelligent controller with multi-segment programmable ramp/soak curves.

• Temperature uniformity of ±1–5°C depending on configuration.

• Maximum temperature up to 1800°C (model-dependent).

• Compatible with thermocouple or optional infrared pyrometry.

2. Vacuum & Atmosphere Control

• Vacuum level down to 10⁻³ to 10⁻⁵ Pa (with optional molecular pump system).

• Supports multiple gas atmospheres including inert (N₂, Ar), reducing (H₂), and custom gas mixtures.

• Ideal for oxidation prevention, material reaction control, and purification processes.

3. Superior Heating Elements

• High-quality Fe-Cr-Al alloy heating wires or optional MoSi₂ / SiC elements.

• Long service life, stable performance across various temperature ranges.

4. Safety & Stability

• Over-temperature protection, power/water failure alarms, and pressure relief valve.

• Double-layer water-cooled chamber keeps the outer shell cool for safe operation.

5. Modular & Customizable Design

• Customizable heating chamber sizes in both box and tube formats.

• Optional upgrades: rapid cooling system, viewing window, material feeding or transfer mechanism.

6. Energy Efficient & Eco-Friendly

• Multi-layer alumina fiber insulation minimizes thermal loss.

• Energy-saving structure with low heat dissipation.
