Rolling Thin-Film Oven 220-240V 50/60 Hz

The Rolling Thin-Film Oven (RTFO) procedure provides simulated short term aged asphalt binder for physical property testing. Asphalt binder is exposed to elevated temperatures to simulate manufacturing and placement ageing. The RTFO also provides a quantitative measure of the volatiles lost during the ageing process.

The exterior is constructed from sheet steel finished in an easy clean powder coated paint and the interior chamber is made from stainless steel.

The control system comprises of a microprocessor digital controller and overheat thermostat with calibrated scale and tamper-proof lock.

Loss on Heat/Thin-Film Oven 220-240V 50/60 Hz

The Thin-Film Oven is used for determining the loss in mass of oil and asphaltic/bituminous compounds when heated with the loss on heating test method or the effect of heat and air on semi-solid asphaltic/bituminous materials with the Thin-Film Oven (TFO) test method.

Features:

  • The exterior is constructed from sheet steel finished in an easy clean powder-coated paint.
  • Interior chamber is made from Stainless Steel.
  • The unit is well insulated and has a double glass door for viewing the test chamber.
  • The system is controlled by a microprocessor digital controller and overheat thermostat.
  • Calibrated scale and tamper-proof lock.
  • Temperature is controlled and pre-set at 163°C +/- 1°C
  • Two rotating platforms of 13.5 inches diameter are supplied to perform both the tests. Side mounted controls comprise:
  • Microprocessor digital control.
  • Independent overheat thermostat.
  • Mains switch.
  • On/off switch for the turntable motor.
  • Indicator lamps.
