Mechanism

At Pulsed Light Power B.V., we make use of the entire ultraviolet (UV) light spectrum, which lies in the wavelength range from 240 nm and upwards. UV is characterised by electromagnetic radiation that is not visible to the human eye.

The operation of the mechanism

As ultraviolet light has a shorter
wavelength than visible light, the energy is richer, and therefore it can reach the ionisation potential of organic molecules and thus trigger a reaction. This reaction causes the microbial population to be reduced significantly.
The mechanism of the microbial in-activation by Pulsed Light Power is mainly explained by the photochemical and photo thermal effect. We generate up to ± 2,000J per flash, so the energy will be absorbed and converted into an electronic field that penetrates into the product. This in turn will create a very short heat up (± 1,400 ° C) through which a natural modification will take place, resulting in cleaving of the DNA and denature of the protein, causing them to lose their function. In addition, this process prevents the cells from replicating.

Ultraviolet light is generated by means of a lamp, which is filled with a specially developed combination of gas mixtures. The combination of our gas mixture, special electrodes and casing designed specifically for this combination of gas mixtures, will cause a gas discharge through which the gasses generate the ultraviolet light.

The system

The Pulsed Light Power sterilisation flash is ready for use. The standard equipment consists of a generator, including the UV lamp in a housing. The lamp housing is connected to the generator and, if needed, can be placed at some distance from the generator. The whole system is very easy to integrate into your existing production process. In addition, you will have the option to request a more “tailor made” housing – one that would include underwater flash as well.
