Rolling Thin Film Ovens provide 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. Rolling thin film As per ASTM D2872.
Units feature a PID controller. A solid-state digital temperature controller with built-in over-temperature protection and 200 Watt heating controls temperature to ±1°F at 325°C (±0.5°C at 163°C). Ovens have enameled steel exterior and double-wall construction.
