In addition to the new equipment existing process ventilation equipment will be re-used, when and where applicable.

Furthermore to the process ventilation delivery also an extension of the existing machine hall ventilation, targeting for improved building ventilation and working conditions both for the new BM2 and the existing PM1, is part of the total EVG delivery. New supply air units with a total capacity of over 100 m3/s will be located into different parts of the buildings, taking into account both process requirements and overall ventilation improvement targets.

The overall delivery includes also the installation and start-up assistance services. The start-up of the new production line is scheduled for the early summer 2016.
