Wallace & Tiernan Replacement UV Lamp, WTL 2000

Replacement germicidal ultraviolet lamp for the Wallace & Tiernan WTL 2000 UV disinfection system. A germicidal lamp loses output steadily through its life while continuing to strike normally, so it is replaced on hours run rather than on failure — running past the rated life is the most common reason a system quietly drifts below its required dose. The matching quartz sleeve for this reactor is item 4102-0508 (410 mm, original part number AAC6187); lamp and sleeve are ordered separately and it is normal practice to inspect the sleeve whenever the lamp is drawn. Wallace & Tiernan is an Evoqua Water Technologies brand, and was part of Siemens Water Technologies before that, so the same equipment is catalogued under all three names and its parts carry Evoqua W3T/W2T and legacy AAC/AAD numbers. Item number 4100-0707. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
