The Camfil Group is a world leader in the development and production of air filters and clean air solutions. We manufacture and supply products that satisfy all the demands at airports to control particulate and molecular pollutants. These products also satisfy the recommendations of EN13779.
The European standard EN 13779:2007 focuses on achieving a comfortable and healthy indoor environment in all seasons with acceptable installation and running costs. It is now a national standard in all countries. It specifies the required filter performance in a system to achieve good Indoor Air Quality (IAQ) taking into consideration the outdoor air.
Various solutions are available depending on the extent of the pollution problem. Molecular filtration may be applied in either the fresh air make-up or recirculation air systems.
Solutions for makeup air are preferred since the principal sources of pollutant are external. These tend to be more heavy duty and reflect the high pollutant concentrations and one-pass operation. Solutions for recirculation applications reflect lower ambient concentrations and multi-pass operation. Continue reading
DB Schenker AB’s parcel centre in Stockholm is the hub of the company’s North European logistics operations.
This is where parcels from Central and Northern Europe come together to be sorted by destination and dispatched. The heart of the centre is the 7,500 m2 hall, where all parcels and packages are conveyed along “scan belts” before they are loaded into containers, or onto pallets, for transportation.
At the parcel centre, packages move automatically along conveyor belts as if guided by an invisible hand. They are scanned by special sensors at parcel machines and sorted by destination. The sensors have to be completely reliable for this system to work properly.
High levels of dust in the hall can lead to problems with the sensors in the parcel machines, resulting in increased error rates and even equipment breakdown. The conventional air purifiers deployed up to now have not been a success, even after undergoing improvements. It has not always been possible to guarantee fully functional and speedy sorting of packages.
This has resulted in increased costs related to downtime and extra labour.
The solution and its implementation:
Today, Carl Zeiss Industrielle Messtechnik GmbH (Carl Zeiss IMT) – a company of the Carl Zeiss Group – has three production sites and more than 100 sales and service centres worldwide. Carl Zeiss IMT is a technology leader for bridge-type and horizontal arm measuring machines as well as instruments for measuring form, geometry and surface.
It sets high standards for everything from use in manufacturing environments to component storage, with special focus on quality, environmental protection and occupational safety.
IMT puts special emphasis on optimising processes and early detection and prompt correction of any defects. The same also holds true for the Schwarz Group which takes over a large part of the logistics activities and warehousing for Carl Zeiss IMT at their Aalen-Ebnat site.
Two large warehouses of approx. 4,000 m² each and a height of approx. 9 m are used for interim storage of components. With stock moved on a daily basis, the stored components soon gather dust. There was a risk that problems would arise during further processing of the components. Carl Zeiss IMT also pays particular attention to occupational safety which also includes healthy indoor air quality in the storage areas. The availability of staff and maintaining their health is top priority.
