The controlled environment is a cylindrical autoclave with a diameter of 2.5 m and a length of 15 m. Liquids and gases can be circulated through the autoclave, and their temperature can be independently controlled in a range from 15°C to 200 °C. The autoclave can be depressurized down to 5 mbar, and pressurized up to 10 bar absolute with a precision of ±2.5 mbar. Gas compositions of nitrogen, helium, sulphur hexafluoride or steam/water vapour can be created with an accuracy of ±1 volume percent. The 76.5 m3 autoclave can accommodate set-ups of up to 8000 kg which can be connected to gas and liquid connections. Due to the high level of automation in the Atmosphere, these can later be exposed to any desired conditions in campaigns of durations up to multiple weeks. Using readily available solutions, we can introduce precise motion (rotational or linear) inside the autoclave in the entire range of available conditions. With the versatility of control and monitoring that the Atmosphere offers, your products and processes can be accelerated on their path to the market in a cost-efficient manner.
