A fundamental property of UV light is that it does not propagate well through the air. As can be seen from the below chart at 5cms or (2ins) from the UV light source 75% of the power has been lost.
To overcome this problem Medixair units comprise 4 tubes built into an array. This allows each tube to reinforce the power from its neighbour. In this way we have been able to construct a power distribution of sufficient intensity to provide the basis for a UVGI – Ultra Violet Germicidal Irradiation – machine.
In addition our engineering design team measured a variety of different materials in order to select an ideal candidate for inclusion as an internal reflector. Through the incorporation of this material in tandem with the multi-lamp array we have been able to produce a very dense and intense power field.
The next stage of product development was to review ways and means to optimise the exposure time of air passing through the unit to the power field.
In this context our research had indicated that many competitive products seek to produce high rates of air flow – seeking to effect a cycle of rapid air change within target room spaces.
Medixair has been constructed on the basis that the purpose of the machine is to destroy airborne micro-organisms within a single pass through the irradiation chamber. This we achieve through controlling the speed of the air during its journey through the Medixair unit. In other words we take the approach that it is better to provide a controlled and wholly appropriate air speed to support the purpose of the machine – rather than to blow air ineffectively at great speed through and past the light source. This approach has now been proven to be effective by virtue of a number of actual case studies (sic).
The level of energy required to kill a variety of micro-organisms is described in the below table. As can be observed, Medixair is capable of eliminating all bacteria and viruses. It will however be noted that certain moulds - e.g. Aspergillus Niger - are especially resilient. At the time of writing a research programme is underway to identify a methodology for eliminating these types of moulds within the current Medixair technology.
In general the range of organisms susceptible to Medixair is such that we can predict a very much improved air quality with attendant benefit in infections.
