Abstract: The present invention is generally directed to a split drive assembly for an ultraviolet (UV) disinfection module comprising one or more UV lamps extending between one or more headers and a cleaning plate having openings therein arranged to substantially coincide with the UV lamps to permit movement of the cleaning plate along the UV lamps, the split drive assembly operatively connected to a moving device, the split drive assembly including a split drive nut having an internal bore for attachment to the moving device, the drive nut comprising at least two portions attached together around the moving device. Other aspects of the invention may include a sleeve guide including an attachment plate to attach the sleeve guide to a surface of the cleaning plate; a sleeve extended from the attachment plate; and an alignment device in contact with a UV lamp, the alignment device attached to the sleeve.

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.
