Indoor air quality: removal of particulate matter and gaseous pollutants, China
CLIMATIC boosts significantly healthier indoor air quality in the visa building of the Royal Danish Embassy in Beijing
As a world’s first, INFUSER installed its CLIMATIC pollution control system on the roof of the visa building of the Royal Danish Embassy in Beijing in January 2016.
Designed as an air purification solution requiring no structural reinforcements to the roof, the CLIMATIC integrates fully with the building’s existing air intake. Today, the CLIMATIC provides clean and breathable air to the staff and visitors to the visa building. The facility managers at the Royal Danish Embassy quickly saw the benefits of having INFUSER’s CLIMATIC system at the visa building. Not only does the CLIMATIC offer a very effective solution to the long lasting problem of inferior indoor air quality, the system also offers the embassy a direct cost saving. By removing the particles from the inlet air stream without the use of conventional filters, the lifetime of the existing ventilation filters has been extended. Frequent filter changes are now a thing of the past!
