  • Full conformity to temperature specifications (time to reach target temperature after switch on, target temperature adjustment after samples insertion) from the Standards
  • Able to maintain a temperature of 163°C ± 0.5°C, or any other user defined test temperature between ambient and 200°C
  • Safety features: Automatic over-temperature switch, door switch, internal light, alarm for door open with fan still running; magneto-thermic switch
  • Integral stainless steel structure, internal and external
  • Door with double-glazed window

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 a Diaphragm pump.

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