How can we be sure that circulated air is clean and not recycled?
Businesses could check with their landlord on how the centralised air handling unit (AHU) conditions and distributes the air within the building. They may procure fresh ambient air from the outside, clean it, heat it or cool it, may even humidify it and then force it through some ductwork around to the designated areas within a building.
Given that the AHU manages a large amount of air and the air flows are usually fast, air circulated within the premise may not be fully cleaned before it is distributed through air ducts. Additional protection systems within the business are recommended, with the air exchanges occurring among the occupants within the premises.
• Mercury-free – Conventional UV lamps contain up to several hundred milligrams of mercury in a liquid or amalgam form. However, UV-C LEDs are mercury -free to prevent spillage in the case of any breakage or disposal.
• Compact footprint – High-power-density UV-C LEDs and advanced controls allow for a much smaller footprint compared to traditional UV sources and their electronic drivers.
• Instant-on/off – Unlike gas discharge lamps, UV-C LEDs can be switched on and off without any warmup times. This enhances power savings and leads to prolonged lamp replacement intervals in batch process applications.
