Abstract: The present invention is directed to a cleaning system for a UV disinfection module. In general, the UV disinfection module may have a pair of headers with a multiplicity of UV lamps extending therebetween. The cleaning system may include a cleaning plate having a multiplicity of openings therein, the openings arranged to substantially coincide with positions of the lamps to permit movement of the plate between the headers; a split wiper assembly including a plurality of wiper portions, each wiper portion mounted in a housing, the split wiper assembly connected to the cleaning plate and substantially encircling each opening, sized such that each split wiper assembly has an inner diameter less than the exterior diameter of a corresponding lamp; and a movement device operatively connected to move the plate between the headers.
