Carbolite Gero TSO Series Rotating/oscillating Reaction Tube Furnace

Overview

The Carbolite Gero TSO Series Rotating/Oscillating Reaction Tube Furnace is an engineered solution for high-temperature thermal processing of powders and granular materials under controlled atmosphere conditions. Designed around a horizontal tube geometry with integrated mechanical oscillation, the TSO furnace applies precise angular reciprocation (±15°) at programmable frequencies (1–8 cycles/min) to dynamically reorient sample containers within the heated zone. This motion enhances convective and diffusive mass transfer between solid particles and process gas, significantly improving reaction kinetics, homogeneity, and overall conversion efficiency—particularly in calcination, roasting, oxidation, reduction, and catalyst activation protocols. The furnace operates up to a continuous maximum temperature of 1100 °C, utilizing high-stability N-type thermocouples and advanced insulation architecture to maintain exceptional axial and radial temperature uniformity across the full heating length (±1 °C typical within ±50 mm of setpoint). Its split-body design—hinged at the rear and supported by pneumatic dampers—enables safe, ergonomic access to the reaction tube without compromising structural integrity or thermal containment.

Key Features

• Horizontal split-body construction with rear hinge and pneumatic damping for smooth, repeatable lid actuation—facilitating rapid loading/unloading of sealed flanged quartz or ceramic reaction tubes
• Programmable oscillation drive system delivering precise ±15° angular displacement at adjustable frequencies (1–8 cycles per minute) to optimize particle exposure and gas–solid interaction
• Two control configurations: EPC3016P1 single-zone controller (24-segment programming) or CC-T1 touchscreen-based triple-zone controller with independent PID tuning per zone
• High-efficiency ceramic fiber insulation minimizing external surface temperature (<60 °C at ambient) and reducing power consumption by up to 30% versus conventional refractory-lined furnaces
• Ethernet interface supporting remote monitoring, data logging, and integration into centralized laboratory automation systems (e.g., LabVantage, Thermo Fisher SampleManager)
• Overtemperature protection circuitry compliant with IEC 61508 SIL 2 requirements; standard on all 1600 °C variants and optional for 1100 °C models
• Robust mechanical architecture rated for continuous operation at 1100 °C with mean time between failures (MTBF) exceeding 25,000 hours for heating elements and insulation assembly

Sample Compatibility & Compliance

The TSO series accommodates cylindrical reaction vessels with outer diameter Ø120 mm and lengths from 330 mm to 930 mm, enabling use of standard quartz, alumina, or silicon carbide tubes. Optional accessories include slotted and non-slotted tubes, gas inlet/outlet flanges with Swagelok®-compatible ports, and vacuum-rated seals meeting ISO-KF 25 and ISO-KF 40 standards. All models are CE-marked and comply with EN 61000-6-2 (EMC immunity) and EN 61000-6-4 (EMC emission) directives. When operated with validated procedures and calibrated thermocouples traceable to NIST standards, the system supports GLP and GMP workflows—including audit trails, electronic signatures, and 21 CFR Part 11–compliant data archiving when paired with Carbolite Gero’s optional DataLogger Pro software suite.

Software & Data Management

Standard controllers provide local programming via front-panel interface with password-protected parameter locking and alarm history storage (≥1000 events). The CC-T1 touchscreen controller adds real-time graphical trend display, CSV export via USB, and Modbus TCP/Ethernet/IP protocol support for SCADA-level integration. Optional DataLogger Pro software enables synchronized acquisition of temperature, oscillation status, power draw, and external sensor inputs (e.g., O₂, CO, dew point) at user-defined intervals (100 ms–60 s resolution). All logged data is timestamped, digitally signed, and stored in encrypted SQLite databases compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Catalyst synthesis and regeneration (e.g., Ni/Al₂O₃, Co/Mo/S, Pt/C) requiring uniform thermal treatment and gas-phase contact
• Thermal decomposition studies of metal nitrates, carbonates, and hydroxides under inert or reactive atmospheres
• Material synthesis including Li-ion battery cathode precursors (NMC, LFP), ferrites, and mixed oxides
• Roasting of sulfide ores (e.g., ZnS, PbS) with SO₂ off-gas capture integration
• Thermogravimetric analysis (TGA) pre-treatment and isothermal hold validation prior to DSC or XRD characterization
• Process development for continuous-flow solid-state reactions where batch-to-batch reproducibility is critical

FAQ

What atmosphere options are supported?
The TSO furnace is compatible with air, inert gases (N₂, Ar), reducing atmospheres (H₂/N₂ mixtures), and oxidizing environments (O₂, synthetic air); gas flow rates up to 5 L/min are supported via optional mass flow controllers.
Can the oscillation parameters be synchronized with temperature ramps?
Yes—the CC-T1 controller allows conditional triggering of oscillation start/stop, frequency change, or angle adjustment based on temperature thresholds or time elapsed within a program segment.
Is third-party calibration certification available?
Carbolite Gero offers UKAS-accredited calibration services (ISO/IEC 17025) for temperature uniformity mapping, thermocouple verification, and controller accuracy validation—traceable to NPL standards.
What maintenance is required for long-term reliability?
Annual inspection of heating element continuity, thermocouple drift verification, and damper lubrication is recommended; no routine replacement parts are required within the first 5 years of normal operation.
Are custom tube configurations supported?
Yes—Carbolite Gero provides engineering consultation for bespoke reaction tube geometries, multi-port manifolds, and integrated thermocouple feedthroughs, subject to mechanical and thermal feasibility review.
