3-Zone Tube Furnace 1200°C – TT-TF3Z-80-1200

High-Performance Three-Zone Heating for Advanced Materials – The 3-Zone Tube Furnace TT-TF3Z-80-1200 is engineered for precise sintering and high-temperature heat treatment of metals, ceramics, nanomaterials, and carbon-based substances. Its split-chamber annular heating system delivers exceptional temperature uniformity across three independently controlled zones, each with a 440 mm heating length, ensuring optimal thermal consistency for batch processing in research and industrial applications.

Versatile Laboratory & Industrial Use – Designed for horizontal operation with a manual top-opening lid, this furnace accommodates easy material loading and handling. The high-precision PID controller stores up to 30 programmable segments, allowing complex temperature profiles to be executed reliably. Protective gases such as nitrogen, argon, and hydrogen can be introduced, supporting vacuum or controlled-atmosphere operations for advanced materials processing in universities, research centers, manufacturing facilities, and aerospace or petrochemical applications.

Furnace Shell & Refractory Insulation – Constructed from Q235 low-carbon steel with a corrosion-resistant, electrostatically treated surface, the furnace shell integrates a double-layer metal frame with a heat-insulating fan system to maintain a low exterior temperature. The multi-layer insulation system, composed of lightweight alumina ceramic fiber and high-quality insulation boards, is asbestos-free and designed to minimize heat loss while reducing energy consumption.

Heating System & Temperature Control – The furnace is equipped with premium HRE metal and ceramic heating elements, arranged in rings or dual sides to ensure even heating. Each of the three zones operates independently for precise thermal management. The PID control panel with SSR/SCR support, along with an international-standard thermocouple, heating status indicator, and over-temperature alarm, provides safe, accurate, and reproducible results.

Vacuum & Atmosphere Compatibility – A 304 stainless steel sealing flange allows for vacuum or controlled-atmosphere operations. The working tube is supplied in high-purity quartz by default, with optional metal or alumina tubes to suit specific applications, making it versatile for research and industrial processes requiring precise thermal and environmental control.

Model Options & Technical Specifications – Available in multiple tube diameters (Φ40–Φ100 mm) and heating powers (5 kW–12 kW), supporting maximum temperatures of 1200–1700 °C depending on configuration. Each zone features independent temperature control and ±1 °C precision, ensuring uniform heating across all sections of the tube.
