ATS Rolling Thin Film Oven

ATS Rolling Thin Film Oven (RTFO): Precision Aging for Asphalt Binders

The ATS Rolling Thin Film Oven (RTFO) sets a new industry standard for simulating the critical short-term aging of asphalt binder materials. This process is vital for accurately predicting how asphalt will perform under real-world conditions immediately after mixing and paving, influencing road longevity and performance.

At the heart of the RTFO is an advanced 6-inch (152mm) full-color touchscreen controller. This intuitive interface provides precise control over all customizable test parameters, making setup quick and reducing the need for extensive training. During operation, it meticulously collects and displays crucial temperature and airflow data, ensuring the integrity and repeatability of your tests. A built-in timer even allows for automatic preheat scheduling, optimizing laboratory efficiency.

Designed to meet and exceed rigorous international standards, including ASTM D2872, AASHTO T 240, EN, and California test methods (CTM 346), the RTFO guarantees compliance and reliable results for a wide range of applications. Its unique design also offers the flexibility for users to set custom parameters, making it adaptable for specialized research and development needs beyond standard testing.

Unparalleled Accuracy and Safety:

• Temperature Control: A NIST-traceable Platinum RTD temperature sensor delivers exceptional precision, maintaining temperatures to an astonishing ±0.1°C with oven uniformity to ±1°C. This ensures consistent thermal exposure for all samples.
• Rapid Recovery: The oven heats to its set-point in just 20 minutes, and achieves full temperature recovery in 8 minutes or less after samples are loaded, significantly enhancing throughput without compromising test conditions.
• Safety Features: Critical safety is ensured with a thermal shutdown switch providing 215°C (419°F) over-temperature protection, safeguarding both equipment and personnel. The maximum rated operating temperature is 200°C (382°F).
• Airflow Precision: A NIST-traceable digital flow meter accurately displays airflow from 0–5,000 ml/m with an accuracy of ±0.8%. Consistent and precise airflow is fundamental to the RTFO test, ensuring accurate simulation of aging. Operation requires a source of clean, dry compressed air at 100psi (6.9bar).

Enhanced Usability and Durability:

• Remote Connectivity: For modern laboratories, the RTFO can be connected to the internet, allowing for convenient remote monitoring and control of ongoing tests, increasing operational flexibility.
• Redesigned Carousel: The completely redesigned carousel system simplifies sample handling. It quickly secures bottles with a gentle push, eliminating fragile hardware and preventing scratches to samples. Soft, high-temperature silicone compression gaskets securely grip RTFO Bottles, allowing for easy, scratch-free insertion and removal. A set of eight serial-numbered RTFO Sample Bottles is included.
• Easy Maintenance: A removable tray at the bottom of the case provides easy access for cleaning and maintenance of heating elements, extending the life of the instrument and minimizing downtime.
• Robust Construction: The benchtop RTFO features a double-wall stainless steel case construction for superior insulation, durability, and safety, complete with leveling legs for stable placement.
