Rolling Thin Film Oven
Model A-720 Rolling Thin Film Oven is preferred by SHRP for simulating short term aging of asphalt binders by measuring the effect of heat and air on a moving film of semi-solid asphaltic material. Maximum temperature is 400ºF (204ºC). The circular test rack holds up to 8 special glass containers (included) and rotates at 15 rpm. Complete dry air piping assembly including pressure regulator and gauge, flow control, flowmeter and moisture indicator allows single point connection to dry air supply. Large observation window in door provides clear view of sample bottles and thermometer.
