High Temperature Vertical Crucible Furnace with 22L Heating Chamber and 1200C Maximum Temperature

Product Overview

This high-temperature vertical crucible furnace represents the pinnacle of thermal processing technology, specifically engineered for material science research and industrial R&D. By providing a substantial 22-liter capacity within a vertical orientation, this system allows for the heat treatment of large-volume samples or multiple smaller crucibles simultaneously. The core value of the equipment lies in its ability to provide an exceptionally uniform temperature field, ensuring that every batch of material undergoes consistent thermal cycles, which is critical for experimental reproducibility and industrial quality control.

The primary use cases for this unit span across prestigious universities, scientific research institutes, and demanding industrial or mining enterprises. Whether utilized for high-temperature sintering of ceramics, metal annealing to modify mechanical properties, or rigorous quality inspection protocols, the furnace delivers reliable performance. Its vertical loading design is particularly advantageous for processes that require specific atmospheric buoyancy or ease of access through a top-loading hinged cover, making it a versatile workhorse in modern metallurgical and chemical laboratories.

Confidence in this system is built upon a robust engineering foundation. Featuring a double-shell steel structure with integrated air cooling, the equipment maintains a low surface temperature even when the internal chamber reaches its 1200°C maximum. This design choice not only protects laboratory personnel but also ensures the longevity of the internal electronic components. The use of high-purity alumina fiber insulation and precision-embedded heating elements reflects a commitment to energy efficiency and thermal stability that industrial buyers demand for long-term operational success.

Key Features

• Spacious 22-Liter Heating Chamber: The oversized chamber, measuring φ320 x 280mm (12.5" ID x 11" H), accommodates substantial sample volumes, making this unit ideal for scaling up experimental processes or treating bulky components that standard laboratory furnaces cannot house.
• High-Purity Alumina Fiber Insulation: This system utilizes advanced alumina fiber material which provides superior thermal resistance and energy efficiency. This insulation reduces heat loss and allows for a faster temperature ramp-up while maintaining excellent temperature uniformity across the entire hot zone.
• Precision PID Temperature Control: Equipped with a 30-segment programmable controller, the furnace allows for complex thermal profiles including precise heating rates, cooling rates, and dwell times. The PID algorithm maintains a strict ±1°C accuracy, ensuring process integrity.
• Embedded Heating Element Design: The heating elements are strategically embedded within the insulation layer. This configuration maximizes heat transfer to the chamber while protecting the elements from mechanical damage during the loading and unloading of crucibles.
• Enhanced Safety Protocols: The equipment includes an automatic power cut-off function that activates when the chamber door is opened, significantly reducing the risk of electrical or thermal injury to the operator. Built-in overheat and thermocouple burnout protection provide further operational security.
• Double-Layer Steel Construction: The dual-shell design incorporates an active air-cooling system. This creates a thermal barrier that keeps the exterior casing cool to the touch, enhancing laboratory safety and preventing heat-related damage to surrounding equipment.
• Ergonomic Hinged Cover: The top-loading hinged cover is designed for ease of use, allowing operators to load and unload heavy crucibles vertically with minimal effort. This ergonomic feature improves workflow efficiency in high-throughput environments.
• Wear-Resistant Refractory Base: The bottom of the heating chamber is reinforced with high-strength refractory bricks. This prevents the interior lining from being worn down by the constant placement and movement of heavy crucibles, extending the service life of the furnace lining.
• Digital Communication Capability: Featuring a standard DB9 communications port, the system can be integrated with external PC control modules. This allows for remote monitoring, data logging, and advanced automation of thermal cycles through specialized software.
