Rolling Thin Film Oven
Rolling Thin Film Oven
Supports the following standards: ASTM D2872, AASHTO T240, CAL #346, EN12591
The Rolling Thin Film Oven (RFTO) is used to measure the effect of heat and air on a moving film of semi-solid asphaltic material and is an indicator of the approximate change in properties during conventional hot-mixing. The results of this treatment are determined from measurements of the asphalt properties before and after the test. Through the use of a programmable, temperature controller and a 4-digit, digital display system, along with a solid-state heater and 200-watt heating element, the oven accurately maintains the specified test temperature of ±1°F at 325°F (±0.5°C at163°C). The specially designed and unique heating solution means that the heat is evenly spread during the test, ensuring results are correct and repeatable. Cox & Sons RTFO is the reference in the world.
The oven also features: double-wall construction; door with double-pane viewing window; symmetrical top and bottom vents; air plenum, and squirrel-cage-type 1725 rpm fan.The RFTO is available in a standard model with a glass flow meter or with a digital flow meter. Both models are identical other than the meter.
The RTFO Oven Includes:
- 200 to 14,000 ml/min flow meter
- Moisture meter
- 0 to 100 psi air pressure gauge with regulator
- Rotating (15rpm) test rack.
- 8 Glass sample containers
Units come with (8) Glass Containers, (1) Jar Tong, (1) Bottle Cooling Rack, (1) 10ft Power Cable, and (1) Bottle Scraper. Overall dimensions 40"W x 36"H x 26"D (1016 x 914 x 660mm). A clean, dry compressed air source is required for oven operation.
