Rolling Thin Film Oven (RTFO)

MO-30F Rolling Thin Film Oven provides chamber temperatures with minimal overshoot for measuring the effect of heat and air on a moving film of asphalt binder. This simulates short-term aging during production, handling and paving operations as a controlled flow of heated air is directed into rotating glass bottles.

It features a PID controller, Resistance Temperature Detector (RTD) and dual four-digit display for simultaneous viewing of actual and set point temperatures. A solid-state digital temperature controller with built-in over-temperature protection and 200 Watt heating controls temperature to ±1°F at 325°F (±0.5°C at 163°C). Ovens have enameled steel exterior and double-wall construction. Older MO-30 units can be upgraded with a Digital Flowmeter. Optional MOA-12 or Data Logging MOA-14 electronic platinum resistance thermometers (PRT) can be specified when ordering a new oven, or ordered separately. These precision thermometers are accurate to ±0.05°C (±0.09°F) and are acceptable alternatives to mercury thermometers and avoid regulatory restrictions. Compare our Rolling Thin Film Oven models.
