Weather protection “CamVane intake grille” solved moisture problems at Copenhagen Airport
Camfil and Copenhagen Airport have had a successful collaboration for many years to ensure that the airport’s indoor environments are well filtered from harmful particles and gases. When moisture problems were discovered in a specific weather-exposed air handling unit, Camfil was asked to help solve the issue. The solution was intake grilles designed for efficient separation of moisture and wetness from the airstream, to protect the duct system and the air handling unit.
Results
Protection of filters and ventilation systems
More efficient filtration solution & reduced maintenance needs
Cost savings on filters, equipment & labour time
Focus on air filtration
Copenhagen Airport was founded in 1925 and was therefore one of the first commercial airports in the world. Since then, both the commercial aviation industry and Copenhagen Airport have undergone enormous development. This development still places Copenhagen Airport at the forefront, with millions of travellers passing through every year.
All airports face the challenge that large volumes of outdoor air enter terminals and other buildings – air that is often filled with hazardous particles and gases. The sources of these pollutants are both the aircraft and the vehicles used to support aviation.
Copenhagen Airport works in a focused way to protect the health of both air travellers and the airport’s many thousands of co-workers, investing significant resources to filter out exhaust and other air pollutants from the indoor air.
For this purpose, a ventilation system with 2-stage filtration has been installed. The ventilation system consists of particle filters with filter class ePM1 60% as well as molecular filters for the filtration of gases and molecules (carbon filtration).
Long-term collaboration
Camfil has a long and very good collaboration with Copenhagen Airport, where Camfil's air filters clean the air via the ventilation systems.
This is why Camfil was contacted when co-workers from the Climate Technology Group at Copenhagen Airport discovered moisture problems in a specific ventilation system.
The ventilation system is installed facing the Öresund, where two air intakes are placed low and installed facing east. Driving rain and salt water therefore enter the system and make both the ventilation filters and the system itself damp.
The result is that the wet filters often have to be replaced, and the salty water in the system destroys the bottom plate in the system, which is of course an undesirable extra cost in terms of equipment and time.
We find that the solution works perfectly and that we save time and money. That is why we have chosen the same solution for the other plants as well.Climate Technical Group, Copenhagen Airport
The solution
The solution was Camfil’s CamVane weather louvre, designed to protect ventilation systems and ducts.
CamVane was installed in the air intake, where it effectively captures and drains water droplets from the airflow. This protects the high-value equipment while maintaining low sound levels and low pressure drop across the ventilation filters. Before CamVane could be installed, it was necessary to replace the base plate, which had been affected by rust and corrosion.
The new CamVane weather louvres have now been installed for over 3 years and have clearly proven that they prevent water from entering the system. As a result, the base plate in the system no longer corrodes and the filters no longer need to be replaced due to moisture.
The positive result has therefore led Copenhagen Airport to invest in additional CamVane weather louvres for other facilities with similar issues.
