UV-C SYSTEMS FOR AIR CONDITIONING DUCTING
In today ’ s world , indoor air is 80 to 100 times more polluted than outdoor air . People spend 90 % of their time indoors , with indoor air generally filled with contaminants such as bacteria , viruses , moulds and mildew . 80 % of air conditioned air is also re-circulated .
Infection can be spread in many ways , but the two predominant transfers of infection are via contact and inhalation . Up until now , the conventional defence against infection has been surface cleaning and hand washing . Currently , however , nothing is done to sterilise the air and reduce the risks from the inhalation of airborne micro-organisms .
In-duct air sterilisation is now available through Distributair ’ s UV-C offering . This solution offers :
• Delivery of indoor sterilised air 24 / 7
• Systems can be custom designed
• Only quarterly cleaning and annual lamp replacement required
• Environmentally-friendly with no use of chemicals
• Lamps disposed of in an environmentally-friendly manner
• Only the highest quality lamps are used with the least mercury content
