water conditioners for air conditioning systems

NAR-SHIELD is a water conditioners , multifunctional liquid for cooling water treatment that contains no chromates or heavy metals and is therefore environmentally safe. NAR-SHIELD offers dispersion as well as scale and corrosion control in one simple-to-use chemical. NAR-SHIELD utilizes polymer and phosphonates for scale control. Corrosion control is maintained by the formation of a protective film on metal surfaces. NAR-SHIELD also contains dispersants and peptizing agents to keep heat transfer surfaces free of insoluble materials such as silt, sand and air-borne dirt particles. Continuous type treatment with NAR-SHIELD recommended in all cases for maximum results. The average treating rate for NAR-SHIELD is 20-50 ppm, although higher rates may be required under severe conditions.

NAR-CIDE is one of our patented water conditioners , it is a polymeric quaternary ammonium micro biocide that is especially effective in controlling algae, iron bacteria, and other slime forming microorganisms that contribute to biological fouling of cooling towers, heat exchangers, and other parts of recirculation water systems. NAR-CIDE is a highly concentrated biocide and should be used at the rate of 12 to 120 parts per million. The frequency of the treatment depends on the amount of bleed off and the severity of the microbiological fouling problem. For reasons of determining purchase quantity, treatment every four days should be a good average. NAR-CIDE is compatible with all types of commercially available water treatment products including polymers and chromates. NAR-CIDE is excellent when utilized as a single treatment biocide or may be used in conjunction with other types of biocide to reduce the possibility of development of resistant strains of microorganisms.
