Description and Use

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

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 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-

bromo-2-nitropropane-l,3-diol (BNPD) and 2.6%

Isothiazolone (1.9% 5-chloro-2-methyl-4 isothia-

zolin-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 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
