The new Gilson Rolling Thin Film Oven (RTFO) manufactured in cooperation with ATS and features advanced design, durable construction and reliable accuracy to measure the effect of heat and air on asphalt binder properties. A controlled flow of heated air is directed into the openings of horizontal glass bottles as they rotate on a carousel rack, simulating short term aging of binder during production, handling and paving operations. Precision components ensure precise, repeatable results and straightforward operation with minimal training. The temperature controller is easily programmed for test temperature of 163°C (325°F), and maximum temperature is rated up to 215°C (419°F). The unmatched Gilson MO-36 is CE-marked and Made in the USA, meeting all test method specifications while exceeding recovery time requirements.
The built-in platinum RTD temperature sensor precisely controls temperatures to ±0.1°C, assuring oven temperature uniformity of ±1°C. Time from ambient to 163°C (325°F) set point is 20 minutes, and full heat recovery is 5 to 8 minutes after loading of specimens. A thermal shutdown switch provides over-temperature protection at 215°C. Operating airflow of 0-5,000 mL/m is indicated on the flow meter with a range of 200 to 14,000 ml per minute. A source of clean, dry compressed air is required for operation at 100psi (6.9bar). Soft, silicone compression rings in carousel slots grip RTFO Bottles securely while allowing easy, scratch-free insertion and removal. This time-saving improvement eliminates costly downtime related to spring clamp system breakage in existing RTFO models. Cleaning and access for maintenance of the elements is easy with the removable tray at the bottom of the case. The rugged double-wall stainless steel case is designed with leveling legs for convenient bench-top operation.
