Throughout the last decades UV systems in Europe mainly took place in the potable water sector, but also in water preparation for air moisturizers. Particularly in the sensitive sector of technical air conditioning the effectiveness and efficiency of UV systems continuously could be proven.

At the same time technical advances in ultraviolet systems have been made especially in terms of the ballast technology. The systems of today have greatly improved output and the energy requirements have dropped greatly with the application of modern electronic ballasts. Compared with an installation based on a Cold Cathode Lamp nowadays a UV ray source is able to gain a three times higher UV output at a 55% reduced power consumption.
