UV-C Air 515

UV-C Air 515: Design

The system has been developed in a modular setup by the means of the addition of lamp frames. The lamps are mounted in a frame in order to facilitate easy maintenance and accessibility to the UV reactor chamber. The system can be scaled up to a maximum of 6 lamp frames, and the system is delivered with a minimum of 2 lamp frames. Two lamp frames, one placed in the upper channel and one in the lower, is called a UV Lamp Module, and the system is scaled accordingly. Additionally, due to the compressible and turbulent behavior of gaseous media such as air, the system has also been designed with the distribution of flow across the reactor in mind, as this enables efficient utilization of the lamps.

The lamps used in the system are "UVC High-Performance (HP)"-Lamps, that excels in its ability to achieve high lamp power output and therefore high reaction rates with a minimum footprint. HP lamps can achieve an output up to three times higher than that of standard mercury lamps with the same dimensions while providing emission efficiencies of equal or even better than that of standard low pressure lamps. The graph below shows a comparison between the lamp types.

Due to the high reactivity of ozone and hydroxyl radicals, the system’s interior is constructed in highly resistant materials, where the metal used is the premium quality corrosion resistant AISI 316L (EN 1.4404), that has proven resistance to exposure of ozone. 

The system utilizes standard connection joints (PG, alternatively flange connection) used in rectangular ventilation systems allowing for installation of the system without the risk of incompatibility between the reactor and ventilation. Furthermore, the modular reactor can be installed in sequence if higher flow rates than the specified range is required.

The ballasts required for the UV lamps are supplied in a specialized cabinet, optimized in terms of space and cooling required that ensures the maximum lifetime of both the ballasts and the UV lamps.
