Water & Process Technologies Microbiological Control Agent • Broad spectrum antimicrobial • Patented blend minimizes microbial resistance • Non-foaming, water-based • Compatible with all corrosion and deposit con- trol treatments • Synergistic with halogen-based • Contains no copper or iron stabilizers Spectrus* NX1100 is a proprietary blend of antim- icrobial agents, specifically formulated for industrial water applications. It may be used in open or closed recirculating cooling water systems. Spectrus NX1100 is also approved for use in auxiliary water systems as well as wastewater and waste material disposal applications. The product label provides a complete listing of approved end uses. iNOTE TO CALIFORNIA USERS At the present time, the State of California has ap- proved this product for use in recirculating cooling systems (evaporative condensers, heat exchange water systems, commercial and industrial cooling towers) and brewery pasteurizers, only. Consult the California version of the Spectrus NX1100 product label for a complete listing of approved end-uses Spectrus NX1100 is EPA registered for control of a wide range of microbial species, including aerobic bacteria, anaerobic bacteria, algae, yeast, and fungi. Control of microbiological populations in in- dustrial water systems is essential to prevent bio- fouling. In cooling systems, biofouling of heat exchange equipment and tower fill reduces heat transfer efficiency and can force unscheduled shut- downs and extended turnarounds leading to lost production. Biofouling can also damage equipment through microbiologically influenced corrosion (MIC). As a result of these effects, biofouling must be prevented in order for operating units to achieve profitability goals. The actives in Spectrus NX1100 consist of 5.3% 2- one). Compared to single-active, Isothiazolin-based products, the combination of actives in Spectrus NX1100 gives better microbial control at lower dos- ages (see chart). This blend of actives also limits the development of resistant microbial populations and eliminates the need to alternate products to main- tain microbiological control. Spectrus NX1100 is synergistic with chlorine and bromine disinfection programs. It demonstrates in- creased efficacy in the presence of these oxidizing agents. This means that continuous halogenation does not have to be interrupted or suspended when Dosages Required to Achieve 90% Inhibition Bocterio A SRBs Fungi 1*Based on lob studies using pure cultures; lowest dosoo,e indicates superior performance!

this product is fed into a cooling system. This is especially important when organic contamination leads to rapid microbial growth. Spectrus NX1100 is water-based to minimize impact on the environment. It contains no metalbased stabilizers, such as copper or iron, thus simplifying customer compliance with NPDES permits. The Environmental Fate and Effects (aquatic toxicity and biodegradation) data package for this product is listed in Section 12 of the Material Safety Data Sheet.
