CO2 module

The use of inert gases or inert heat transfer media is required in numerous process engineering plants. Carbon dioxide is often used because of its availability and favourable operating conditions.

The program determines the properties of carbon dioxide depending on temperature and pressure. The vapour pressure, the saturation temperature and the required material properties for the determined aggregate state are defined.

Ranges of validity:

Single phase

Temperature:  -55 °C up to 900 °C

Pressure: 1 bar up to 2000 bar*


Temperature: -56 °C up to 30 °C
