Product Features
Refractory insulation materials
The furnace lining is made of vacuum-formed high-purity alumina lightweight material, offering excellent high-temperature resistance and structural stability. Its low heat storage enables fast heating and cooling, improving process efficiency.
The material provides strong resistance to thermal shock, preventing cracking and deformation during rapid temperature changes. Its anti-slag properties ensure a clean chamber and reduce maintenance needs.
With superior insulation performance, the lining minimizes heat loss, enhances energy efficiency, and supports stable, reliable operation in demanding high-temperature applications.
Exhaust gas purification
The system treats organic waste gas by heating it above 760°C, enabling VOCs to oxidize into carbon dioxide and water for effective emission reduction. This high-temperature process ensures stable purification performance and environmental compliance.
It features a specially designed quartz tube structure, with 50 mm diameter at both ends and 150 mm in the center, providing optimized flow and reaction space. The 600 mm heating zone ensures sufficient residence time for complete gas treatment.
This design enhances reaction efficiency, ensures uniform heating, and supports reliable operation in industrial exhaust purification applications.
Air intake
The system is equipped with a 60W blower featuring a bottom air intake design to enhance airflow efficiency and cooling performance. This configuration supports stable internal temperature regulation and improves overall thermal management.
Below 520°C, the blower operates continuously at full power to ensure effective heat dissipation. When the temperature exceeds 520°C, it switches to an intermittent mode, running for 30 seconds every 10 minutes to maintain controlled airflow while conserving energy.
After the insulation phase, the blower resumes full-power operation to accelerate cooling. This intelligent control strategy optimizes energy use, ensures process stability, and extends equipment service life.
Safe temperature control
The system adopts advanced closed-loop control with thyristor module triggering, supporting phase-shift and zero-crossing modes for continuous adjustment of voltage, current, and power. It delivers stable constant voltage, constant current, or constant power output.
A dual-loop structure with inner current and outer voltage regulation ensures fast response to load changes. In overload conditions, output is automatically limited within rated values to maintain stable operation.
This intelligent protection design prevents electrical surges, safeguards heating elements, and ensures safe, accurate, and reliable performance in industrial heating systems.
Applications
The 900°C XL box-type resistance furnace with top exhaust purification is widely used in industries requiring clean and controlled heat treatment processes. It is ideal for metal processing applications such as annealing, tempering, and preheating of steel, alloys, and precision components.
In laboratories and research institutions, the furnace supports material testing, powder sintering, and thermal analysis where a clean environment is essential. The integrated top exhaust purification system effectively treats exhaust gases, making it suitable for processes involving coatings, binders, or organic materials.
It is also applied in ceramics, electronics, and new energy industries for firing, curing, and component processing. With stable temperature control and emission treatment capability, it ensures both process quality and environmental compliance in industrial and R&D applications.
