Rolling thin film ovens (RTFOT)

Category

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.

Small Footprint – at 30″ x 30″ this RTFO oven has the smallest footprint

The Rolling thin film ovens (RTFOT) can be used as part of your Superpave performance-based testing program.
