Xellia Pharmaceuticals had ordered app. 1.000 sqm of multiple-storied facilities for producing pharmaceutical active ingredients (API’s). That kind of project requires not only bricks, but also cooling and ventilation. Furthermore, because this type of building functions on a high degree of cleanliness, air pressure control of the building was a particular point of attention for LBP Engineering – to ensure that dirt is only blown out and subsequently away from the delicate production installations inside.

In order to control the indoor climate, LBP Engineering helped install two new ventilation systems as well as a re-circulation system. This allows for continuous renewal of fresh air and also ensures a constant temperature and humidity. To meet the client’s needs, LBP also installed a large (450 kW) cooling system as well as cooling compressors on the ground floor and a sizeable dry cooler on the roof of the building. Additionally, an extra cooling system was installed for a special cold room for finished pharmaceutical products. All in all, quite a substantial amount of hardware.

”With all this equipment, it has been something of a challenge to put all ventilation ducts and additional cooling systems in place. Some ducts measure more than a meter on each angle, and consequently may greatly affect user behaviour because they take up quite a bit of space. Our approach in these sorts of situations is to listen to the client and assess what is practically possible. Is each system available for maintenance once we are finished? Are all technical installations accessible? These are complicated matters which require both experience and a good solid cooperation with both entrepreneurs and clients,” explains LBP project manager, Allan Christensen.

“There is much to consider in a project like this, and we need to keep our heads cool. In Xellia’s classified areas alone, we have installed H14 filters on all inlet boxes to ensure a clean air supply. Needless to say, the many and large cooling installations are necessary because indoor temperatures need to be kept at approximately 20 degrees Celsius – even on a hot Summer’s day. We need to ensure that these kinds of elements function and that operations managers and other personnel are able to go about their daily business undisturbed,” explains Allan Christensen.
