OTF-1200X-6M 12-Zone Ultra-Long Split Tube Furnace with 5″ OD Quartz Tube, 1100°C Max Temperature
The OTF-1200X-6M furnace is engineered for advanced thermal processing of elongated materials requiring precise temperature control along extended lengths. It is particularly suited for treating long strip samples under vacuum or controlled atmospheres, ensuring uniform heat exposure over a continuous zone nearly 18 feet long by synchronizing multiple heating zones.
This split tube furnace integrates twelve independent heating zones, each 500 mm in length, controlled via a separate touch screen digital controller housed in an external unit. The furnace accommodates a 5″ outer diameter quartz tube, enabling processing of samples within a chemically inert and thermally stable environment. The modular design facilitates shipping and installation of this ultra-long furnace.

Ideal for heat treatment of long strip materials, thin films, and samples requiring uniform temperature profiles under vacuum or controlled atmospheres. Commonly used in materials research, semiconductor processing, and advanced ceramics manufacturing.
구성 및 작동 안내
The furnace is shipped in modular split sections for easier transport and installation. The included quartz tube and stainless steel vacuum flanges support vacuum and low-pressure operation below 0.2 bar. A two-stage pressure regulator must be installed on gas cylinders to limit pressure below 3 PSI for safe use. The furnace supports PC control via RS485 communication; however, the PC is sold separately. Optional accessories include a digital vacuum gauge, molecular pump for high vacuum, and recirculating water chiller for cooling.
Users should calibrate temperature profiles for accurate internal temperature measurement. The furnace is CE certified, with additional certifications available upon request. Vacuum operation is safe up to 1500°C, but quartz/mullite tubes are designed for vacuum and low-pressure conditions only.
