1200C Max Four Zone Split Tube Furnace with Optional Large Diameter Quartz Tubes

Product Overview

This high-performance thermal processing system is engineered to meet the rigorous demands of industrial R&D and advanced material science. Designed as a large-scale, split-able four-zone furnace, it provides exceptional flexibility for researchers and production engineers who require precise temperature gradients or extended uniform zones. The split-cover architecture allows for easy access to the reaction chamber, facilitating the rapid loading and unloading of samples or the integration of complex internal assemblies without dismantling the entire tube setup. By combining a 1200°C maximum operating temperature with specialized large-diameter quartz tube options, this system is uniquely positioned to handle high-volume processing and large-format substrates that standard laboratory furnaces cannot accommodate.

The equipment excels in applications requiring controlled atmospheres and high-vacuum environments. Whether tasks involve the synthesis of advanced ceramics, the annealing of semiconductor wafers, or the sintering of metallic powders, this unit delivers the thermal stability necessary for reproducible results. Its four-zone configuration is optimized to create a massive 36-inch uniform temperature zone, a critical requirement for scaling up laboratory processes to pilot-plant levels. Target industries include semiconductor manufacturing, aerospace material development, energy storage research, and high-purity chemical processing, where consistency and reliability are non-negotiable.

Built with heavy-duty industrial components, this system reflects a commitment to long-term operational excellence. The chassis features a double-layered steel construction integrated with dual cooling fans to maintain a safe, low-touch skin temperature during high-temp cycles. Reliability is further bolstered by the inclusion of high-purity fibrous alumina insulation, which minimizes heat loss and improves energy efficiency. For procurement teams and lab managers, this furnace represents a premium investment in thermal infrastructure, balancing high-throughput capabilities with the precision of a high-end laboratory instrument.

Key Features

• Independently Controlled Four-Zone Design: The equipment features four distinct heating zones totaling 47 inches in length, allowing for the creation of precise thermal gradients or a remarkably long 36-inch uniform zone within ±5°C. This level of control is essential for complex CVD processes and long-sample annealing.
• Pneumatic Split-Cover Operation: To ensure ease of use and operator safety, the top cover is driven by two heavy-duty pneumatic cylinders. This mechanical assist allows for smooth opening and closing of the split furnace, facilitating rapid cooling and easy tube replacement even in high-throughput environments.
• Large-Scale Chamber Versatility: This system supports optional high-purity quartz tubes with internal diameters of 8, 10, or 14 inches. This versatility enables the processing of large wafers, bulky components, or high volumes of smaller samples in a single thermal cycle.
• Precision PID Temperature Regulation: Equipped with four programmable digital controllers, the unit offers 30 segments for managing heating rates, cooling rates, and dwell times. The ±1°C accuracy ensures that even the most sensitive materials are processed within strict tolerances.
• Industrial-Grade Cooling and Insulation: The double-layer steel case is paired with twin cooling fans to ensure the exterior remains safe for contact. High-purity fibrous alumina insulation provides excellent thermal retention while significantly reducing power consumption during extended runs.
• Advanced Vacuum Sealing Technology: The unit includes a pair of stainless steel 304 vacuum flanges featuring double high-temperature silicone O-rings and integrated water-cooling jackets. This ensures seal integrity and longevity, even when operating at the systems upper temperature limits.
• Comprehensive Safety Systems: Built-in overheating and broken thermocouple protection, along with an over-temperature alarm, allow for confident, unattended operation. The system is designed to shut down safely in the event of a thermal excursion, protecting both the equipment and the valuable samples within.
• High-Performance Thermal Elements: Fe-Cr-Al alloy heating elements doped with Mo provide rapid heating and excellent resistance to oxidation. These elements are strategically positioned to provide balanced radiant heat across the entire circumference of the process tube.
• Ready-to-Integrate Digital Communication: An RS485 communication port and specialized software are included as standard. This allows users to monitor and control the furnace via a laptop, enabling data logging and remote recipe management for standardized industrial workflows.
• Optimized Thermal Buffer Blocks: Buffer-type quartz disc thermal blocks are included to maintain the internal cleanliness of the chamber and prevent heat radiation from damaging the flange seals, further extending the service life of the consumable components.
