Replacement ultraviolet lamp for the Hanovia UVEO-H6 and UVEO-H8 systems. UVEO is Hanovia’s PureLine Ultraviolet Energy Optimised range — a single-lamp medium-pressure design that reaches its duty on up to 60 % less power than a conventional multi-lamp system. Because the system runs on one lamp, that lamp carries the entire disinfection duty and there is no redundancy: lamp replacement on schedule is what keeps the system in specification. Medium-pressure UV lamps lose output steadily through life rather than failing outright, so they are replaced on elapsed running hours against the system’s dose record, not when they stop lighting. Reference number 22128-1116.
