Upper room UVGI fixtures are mounted on walls or suspended from the ceiling to continually disinfect air in the room, even while patients are occupying the space. There are many factors that require careful attention that can influence the overall effectiveness of these systems, most importantly the UV dose required to neutralize target microorganisms. New methodologies in directional and reflective control allow the UVC light to extend from wall to wall, maximizing irradiance time while minimizing UV exposure to occupants. Other important factors to consider include:
- Air mixing
- Upper room mechanical ventilation
- Uniformity of UV light dispersion
- Ambient temperature and humidity
The cost of HAI’s
In the US, it is estimated that the cost associated with each infection can reach $15,000 dollars or more, adding nearly $30 billion dollars in additional cost to the healthcare industry. Hygiene and the elimination of infection risk, whether to patients or healthcare professionals, is a top priority.
Crystal IS UVC LEDs offer distinct advantages when designing light fixtures for upper room or free standing units for air disinfection.
- Smaller footprint affords design flexibility for better uniformity of light dispersion
- Robust design
- Environmentally friendly with no harmful byproducts, unlike traditional mercury bulbs which generate ozone
- Quiet operation
- Efficiency and lifetime advantages owing to the specificity of wavelength and instantaneous on-off cycles
