Rotating Bituminous Rolling Thin-film Oven RTO-85A (RTFOT)

It used to measure quality loss of pavement asphalt membrane after heating, thus to judge age resistant property.
ASTM D2872 / AASHTO T240
Voltage: 220V±10%
Working temperature: 163℃ ±0.5℃
Rotating plate speed: 15±0.2rpm
Heating power: 2.0kw
Air flow: 4000±200ml/min
Dimensions: 860×620×720﹙mm﹚
The digital temperature controller automatically controls the temperature, measures accurately, and has an error function.
There is a forced ventilation layer, and air is provided to the lower heat source through a closed fan to make the temperature of the inner tank more uniform.
The fully controlled heating element ensures a high-speed response, and the loss of heat conduction and radiation is very low.
The inner tank plate has a preheating copper tube, and the air is supplied by the air machine in the box through the flow meter.
The variable speed motor ensures the speed of the turntable, the transmission is light, and the noise is low.
The inner tank of the working room is made of stainless steel, and the outer shell is sprayed with plastic, which is beautiful and generous.
The temperature is reset to 163℃ within 10 minutes after the sample is loaded and the door is closed.
There is a timing device, which automatically cuts off the power supply after the aging time is reached to prevent excessive aging.
