Levels of UVC Energy Needed to Destroy Harmful Microorganisms
Each harmful microorganism has a different level of sensitivity to UVC radiation. Some harmful microorganisms require only a small amount of UVGI to break apart their DNA. While other harmful microorganisms require more UVGI. In order to use UVGI to effectively sterilize surfaces, the operator must understand the exposure levels required. The intensity of the UVC light source, the distance from the light source to the target surface and the length of time required for optimum exposure.

960 MiniZapr XL Operational Requirements
The operational requirements of this system are flexible and operators can adjust their protocols to meet their needs. Operators may optimize the UVGI treatment system and design a regular treatment schedule that effectively targets microbes of particular concern. For the optimum results in any setting, the operator should be aware that a slower, deliberate delivery method delivers significantly higher levels of exposure and more effective germicidal efficacy. Of course, a higher germicidal efficacy provides greater confidence for sterility and safety.
