Abstract

The invention relates to a device (10) for UV irradiation, each UV module (14) being designed as an immersible radiator and being in each case formed by a round UV radiator (26) which is designed as a mercury low-pressure radiator and is enclosed by a sleeve tube (28) which is transparent to UV rays, each UV module (14) being assigned an irradiation space (24) having a square cross section, the center of which is also the center (18) of the UV radiator (26) and which in each case extends from the center (18) half-way to the neighboring UV modules (14), the centers (18) of four neighboring UV modules (14) forming the corners of a square (20), the area of which corresponds to the sum of the cross-sectional area (F1) of a UV module (14) and the cross-sectional area (F2) of the irradiation space (24) of a UV module, and in that the spacing of the UV modules (14) from one another is selected in such a way that the cross-sectional area (F2) of the irradiation space (24) of each UV module (14) is no more than 10 times greater than the cross-sectional area (F1) of the UV module (14) itself.
