1200C Hydrogen Atmosphere Box Furnace with 5 Heated Sides and 64L Chamber

Product Overview

This high-performance thermal processing system is a specialized box furnace engineered for material synthesis and heat treatment within a controlled hydrogen environment. Capable of reaching temperatures up to 1200ºC, the equipment provides a robust solution for researchers and industrial engineers working with complex reduction reactions. By integrating a vacuum-sealed stainless steel case with an advanced water-cooling jacket, the unit ensures stable operation under positive pressure while protecting the structural integrity of the furnace during high-temperature cycles.

The primary use cases for this system involve the preparation of advanced materials that require a strictly reduced atmosphere, such as phosphorus compounds and titanium alloys. Beyond hydrogen-rich processes, the equipment is versatile enough to handle heat treatments under inert gases, oxygen, or non-flammable mixed gases. This flexibility makes it a cornerstone tool for laboratories focusing on metallurgy, semiconductor development, and catalyst research where atmospheric purity and thermal precision are non-negotiable requirements.

Reliability is at the core of this unit's design. Featuring industrial-grade Kanthal Fe-Cr-Al alloy heating elements and a multi-sided heating configuration, it delivers exceptional temperature uniformity across the entire 64-liter chamber. High-purity fibrous alumina insulation and a reflective Al2O3 coating maximize energy efficiency, ensuring that the system maintains consistent performance even under the most demanding R&D schedules. The inclusion of a dedicated H2 burning system and automatic safety shut-off valves provides the operational confidence necessary for handling flammable gases in a professional laboratory setting.

Key Features

• Superior Five-Sided Heating Configuration: Unlike standard furnaces that only heat from two or three directions, this system utilizes heating elements on the left, right, bottom, back, and front. This comprehensive coverage ensures the most uniform temperature distribution possible throughout the heating chamber, which is critical for consistent material properties in batch processing.
• Advanced Hydrogen Safety Integration: The equipment is equipped with a built-in hydrogen burning control system. An integrated ignition device incinerates flowing gas and monitors burner temperature; if the system detects a flame failure, the H2 delivery valve is automatically shut down to prevent gas accumulation and ensure facility safety.
• High-Performance Vacuum and Pressure Management: The double-layer stainless steel structure is designed for maximum vacuum integrity and safety, capable of maintaining a positive pressure up to 0.06 MPa and a vacuum down to -0.09 MPa. This allows for rigorous purging protocols and precise control over the internal environment.
• Premium Thermal Insulation: The chamber is lined with energy-saving 1500-grade fibrous alumina insulation and coated with a high-purity reflective Al2O3 layer. This engineering choice reduces heat loss to the external environment, accelerates ramp rates, and significantly lowers operational energy costs.
• Precision PID Temperature Regulation: Utilizing a sophisticated PID controller with 30 programmable segments, the furnace allows for complex ramping, cooling, and dwelling steps. The system maintains a temperature accuracy of ±1°C, providing the repeatable thermal profiles essential for scientific validation.
• Industrial-Grade Kanthal Heating Elements: The unit employs 1300°C grade Kanthal Fe-Cr-Al resistance wires, known for their exceptional oxidation resistance and long-term stability under high-temperature cycling, ensuring minimal downtime for element replacement.
• Integrated Cooling Infrastructure: A heavy-duty water-cooling jacket protects the front door and sealing flanges, while an air-cooled outer shell keeps the exterior surface temperatures safe for operators. A built-in 16L/min recirculating water chiller is included to maintain the integrity of the vacuum seals.
• Comprehensive Gas Flow Control: Two independent large flow meters (for N2 and H2) are mounted on the front panel, allowing operators to transition seamlessly from inert gas purging to active hydrogen introduction with high volumetric precision.
