OTF-1500X-6Z Six-Zone Split Tube Furnace with Alumina Tube and Hermetic Flange
The OTF-1500X-6Z is engineered for advanced laboratory and industrial applications requiring precise thermal processing under controlled atmospheres. It is particularly suited for tasks involving high-temperature treatments up to 1500°C, such as material synthesis, annealing, and sintering within a sealed environment provided by its hermetic flange design.
This furnace incorporates a long alumina tube (standard 60 mm outer diameter, 51 mm inner diameter, 1800 mm length) that serves as the processing chamber. The tube is split into six independently controlled heating zones, allowing for precise temperature gradients and uniformity along the 1400 mm heating length. Each zone is managed by a dedicated PID controller with S-type thermocouples, ensuring temperature stability within ±1°C and programmable heating profiles with up to 50 segments.
Wichtigste Merkmale
- Six heating zones with lengths of 200 + 200 + 300 + 300 + 200 + 200 mm for tailored temperature control.
- Maximum temperature of 1500°C for short durations; continuous operation recommended between 800°C and 1400°C.
- Hermetic stainless steel flanges with water cooling and multiple fittings for controlled atmosphere and vacuum applications.
- 48 silicon carbide heating elements rated for 1500°C ensure efficient and stable heating.
- PID controllers with 50 programmable segments and built-in safety features including over-temperature and broken thermocouple protection.
- RS485 communication port for external monitoring and control software compatibility.
- Optional upgrades include Eurotherm 3000 series controllers for ±0.1°C accuracy and a handheld touchscreen panel for enhanced control and data logging.

Hinweise zur Konfiguration und zum Betrieb
The furnace includes two thermal blocks and six S-type thermocouples, one per heating zone. Vacuum pumps and water chillers for flange cooling are not included and must be sourced separately. The furnace supports optional upgrades for enhanced temperature control accuracy and user interface. For uniform temperature zones up to 1200°C, all six zones can be set identically without zone spacers; removal of spacers requires prior consultation. Proper water cooling and pressure monitoring are essential for safe operation.
