Ultraviolet disinfection Cabinet


Marlin Labs has developed a Sanitiser cabinet for disinfection of hospital and daily use items including PPE. The device uses UV-C in its operation. UV light is electromagnetic radiation with wavelengths shorter than visible light but longer than X-rays. UV can be separated into various ranges, with short-wavelength UV (UVC) considered “germicidal UV”. Wavelengths between about 200 nm and 300 nm are strongly absorbed by nucleic acids. The absorbed energy can result in defects including pyrimidine dimers. These dimers can prevent replication or can prevent the expression of necessary proteins, resulting in the death or inactivation of the organism. Sterilization” is often misquoted as being achievable. While it is theoretically possible in a controlled environment, it is very difficult to prove, and the term “disinfection” is generally used to avoid legal reprimand. The effectiveness of this form of disinfection depends on line-of-sight exposure of the microorganisms to the UV light. The required UV dose is as follows μWs/cm2 = UV intensity μW/cm2 × exposure time (seconds)
Please see a sketch below showing our concept. The main box is manufactured from Aluminium and powder coated white. Any colour is possible. Internally the device is fitted with a mirror finish stainless steel tube 350mm dia and fitted with a aluminium plate as a floor. Mounted to the top of the tube running its entire length is a CE/TUV marked and certified 55W Ultraviolet C wavelength light source.
