Loss on heating of asphaltic compounds

The apparatus consists of a convection oven manufactured as described in the ASTM E 145 specification (type IB), suitable for temperatures up to 180°C and equipped with a rotating shelf inside. An electronic controlled motor with gear reducer mounted on the top of the oven rotates the shelf at 5.5 rpm.

  • Enamel finished steel case, benchtop model.
  • Stainless steel interior with plenum fan for air circulation. Internal dimensions 380 x 380 x 380 mm. High efficiency thermal insulation.
  • Stainless steel heater.
  • Hinged door fitted with double wall window 300 x 200 mm, for internal view.
  • Two openings, one on the bottom and one on the top for ventilation.
  • Anodized aluminium horizontal rotating shelf 300 mm diameter, capable of supporting nine ASTM D 6 or three ASTM D 1754 sample containers. The shelf is suspended by a vertical shaft, centered with the horizontal interior dimensions and vertically located in the centre of the oven.
  • Electronic controlled motor, 1/4 HP with built-in gear reducer that provides to rotate the shelf at a speed of 5.5 rpm.
  • Microprocessor controlled thermoregulator with PID action and built-in digital display, 0.1°C accuracy. Probe: Pt100 RTD. Working range: from ambient to 180°C ± 1°C.
  • Safety device against overheating.
