Air treatment covers mainly the conditioning of air for processes like the climatisation of paint application booths, flash-off zones and eventually industrial area's and the extraction of matter and/or smell from an airflow.
The design of air-conditioning systems for offices and buildings is definitely not scope of the services rendered by PLOUM Engineering.
Gas treatment covers industrial processes taking place in equipment and systems where these media are entering in a specific condition and are treated to obtain another required condition. The reasons can be as well from process technical as from, for example, environmental point of view.
PLOUM Engineering can design as well these processes as the required equipment as draw up the technical specifcations for this, but does not supply any equipment.
