DESCRIPTION AND USE

Spectrus NX1103 is EPA approved for control of bacteria, algae, and fungi in a variety of industrial water-based systems. Spectrus NX1103 consists of a proprietary blend of 10% dodecylguanidine hydrochloride (DGH) and 5% methylene bis (thiocyanate) [MBT].

Spectrus NX1103 is approved for use in open recirculating cooling systems, heat exchange systems and evaporative condensers.

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. Equipment can also be damaged as a result of microbiologically influenced corrosion (MIC) associated with biofouling.Consequently, biofouling must be prevented in order for operating units to avoid such events and achieve profitability goals.

Compared to single active biocide products (see Chart), the combination of surface active agent (DGH) and metabolic inhibitor (MBT) in Spectrus NX1103 work together to provide faster microbial control at lower dosages. The blend of actives in Spectrus NX1103 also limits development of resistant microbial populations and reduces the need to alternate products to maintain effectiveness.

In addition to cooling systems, Spectrus NX1103 can be used to control microbes in influent water systems, air washers, pasteurizers, and water-based scrubbers. See the Spectrus NX1103 product label for a complete listing of approved end uses.

TREATMENT AND FEEDING REQUIREMENTS 

Correct treatment levels and frequency of Spectrus NX1103 addition depend on many factors.
