EN 12607-1 | ASTM D2872 | AASHTO T240
Main features
  • Full conformity to temperature specifications (time to reach target temperature after switch on, target temperature adjustment after samples insertion) from the Standards: 8 minutes of time to target;
  • Touch-screen display with 4.5” color control panel, including timer function, visual warnings and digital air flow regulator;
  • Air flow regulation from 0.1 up to 10000 mL/min;
  • High performance thermoregulator reaching the target temperature quicker than the Standards minimum requirements (8 minutes versus 10);
  • Carousel rotation with closed-loop controlled speed;
  • Safety features: Automatic over-temperature switch, door switch, pilot lamp and alarm for door open with fan still running; magnetothermic switch;
  • High quality stainless steel structure, internal and external;
  • Door with double-glazed window;
  • Door locking system allowing easy opening also with busy hands.
General description
General description
These ovens are used for measuring the effect of heat and air on a moving film of semi-solid bituminous materials. The internal chamber is made from stainless steel, insulated with fiberglass or similar, with an external frame made from engine-turned stainless steel and a door with a centrally located window.
The high perfomance thermoregulator of the rolling thin film oven ensures a time saving test execution: 8 minutes (versus 10 specified by the Standards as maximum time to target temperature) are sufficient to reach 163 +/- 0.5 °C in a typical laboratory environment.
Special attention has been given to the safety features which conform to CE requirements. The oven includes 4.5'' touch-screen control panel including timer function, visual warnings and digital air flow regulator. The oven is supplied complete with ASTM 13C thermometer and 8 heat resistant glass containers (64 mm diameter x 140 mm high).
The oven must be connected to a compressed air source supplying 2 bar maximum pressure. If not available in the laboratory we recommend the 81-PV0161/12 Diaphragm pump. See accessories.

Two versions are available:
  • 81-PV1612 conforming to ASTM/AASHTO standards
  • 81-PV1622 conforming to EN standard
The difference between the two models is the inside dimension of the testing chamber.
