Upper-room air disinfection
In rooms where patients, visitors or employees are present and the ceilings have a limited height UV-C can still be used in a very effective way.
By making use of parabolic reflectors, and non-reflective lamellas, the UVGI can be concentrated in a zone. This zone is used to disinfect the air, often above 240cm. in a room. In this zone a high intensity UV-C is realized without having too high intensities below 200cm.. Because of the presence of natural or mechanical ventilation in the room, the contaminated room-air will pass through the UV-C zone and thus will be disinfected. This method is also called zone irradiation or upper air irradiation.
See our new leaflet.
Scientific research has demonstrated the effectiveness of UVGI systems, e.g. Escombe AR, Moore DAJ, Gilman RH, Navincopa M, Ticona E, et al. (2009) Upper-Room Ultraviolet Light and Negative Air Ionization to Prevent Tuberculosis Transmission. PLoS Med 6(3): e1000043. doi:10.1371/journal.pmed.1000043.
Examples of applications are:
- Upper-room air disinfection is mainly used for the prevention of Tuberculosis. This is also a specific specialization of G.L.A. in which we have performed many projects in The Netherlands and abroad. In addition to the products, G.L.A. also has provided training and advice for various development organizations like MSF, KNCV & USAID on-site in middle and low income countries. For these countries G.L.A. has developed a low cost, high quality fixture that can be applied in any situation, the APF-WM. Ask for the special conditions that apply to you.
- Also in hospitals, laboratories, the food processing industry and horticulture this form of air disinfection has been applied.
- Increasingly mobile units are used for screening, diagnosis and treatment purposes. For these units, upper-room air UVGI is a very effective air disinfection method too.
We can help you with planning and installing your UVGI system. To keep your system in perfect condition and maintain optimum performance, G.L.A offers you the opportunity to outsource the specialist maintenance. For foreign customers we offer this service as well or we have SOP's (Standard Operating Procedures) available.Back to the homepage
