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.

Special attention has been given to the safety features which conform to CE requirements. 
The oven is supplied complete with flow meter, ASTM 13C thermometer and 8 heat resistant glass containers (64 m high x 140 mm diameter).
The oven must be connected to a compressed air source supplying 2 bar minimum presure. If not available in the laboratory we recommend to order Diphgram pump (see accessories).

Two versions are available:
81-PV1612 conforming to ASTM/AASHTO standards
81-PV1622 conforming to EN standard
The ASTM and EN versions are basically identical, except for a small difference of the internal dimensions of the testing chamber.
 

Features:

    • Touch-screen display with 4.5” color control panel, including timer function, visual warnings and digital air flow regulator
    • Full conformity to temperature specifications (time to reach target temperature after switch on, target temperature adjustment after samples insertion) from the Standards
    • 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
