Spectrus* NX1100 is a proprietary blend of antimicrobial 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.
- Note To California Users:
At the present time, the State of California has approved 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 and recommended dosages.
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 industrial water systems is essential to prevent biofouling. In cooling systems, biofouling of heat exchange equipment and tower fill reduces heat transfer efficiency and can force unscheduled shutdowns 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- bromo-2-nitropropane-1,3-diol (BNPD) and 2.6% Isothiazolone (1.9% 5-chloro-2-methyl-4 isothiazolin- 3-one and 0.68% 2-methyl-4-isothiazolone-3-one). Compared to single-active, Isothiazolin-based products, the combination of actives in Spectrus NX1100 gives better microbial control at lower dosages (see chart). This blend of actives also limits the development of resistant microbial populations and eliminates the need to alternate products to maintain microbiological control.
Spectrus NX1100 is synergistic with chlorine and bromine disinfection programs. It demonstrates increased efficacy in the presence of these oxidizing agents. This means that continuous halogenation does not have to be interrupted or suspended when this product is fed into a cooling system. This is especially important when organic contamination leads to rapid microbial growth.

Treatment and Feeding Requirements
Correct treatment levels and frequency of Spectrus NX1100 addition depend on many factors. They include, but are not limited to, system cleanliness, nutrient concentrations, temperature, types of microorganisms, pH, retention time, and other system operating characteristics. Consult the product label for general dosage guidelines. Microbiological monitoring is recommended to evaluate product requirements. Consult your Veolia representative for technical advice about your specific application.
In all cases, this product must be applied in accordance with use instructions on the Spectrus NX1100 label.
Feed point – Spectrus NX1100 should be applied to a point in the cooling system where turbulence and flow patterns assure good mixing with the water being treated.
Dilution – This blend is best fed neat (undiluted) from the storage container.
Compatible Materials – Spectrus NX1100 is compatible with most plastics, such as polyvinylchloride (PVC), high density, cross-linked polyethylene (HDPE), polypropylene (PP), and Teflon (Teflon is a registered trademark of DuPont.) (PTFE). Avoid: Mild steel, copper and copper alloys,
aluminum, galvanized metals, 304 stainless steel, and thin-wall 316 SS tubing.
