1、PRODUCT BULLETINWET-4305 SeriesCLOSED LOOP TREATMENTDESCRIPTIONWET-4305 Series is a multifunctional liquid closed system treatment. It is a liquid blend of corrosion inhibitors, scaleinhibitors, polymeric dispersants, copper corrosion inhibitors and a pH buffer to prevent scaling and corrosion from
2、occurringin the closed system. It functions as a protective film-forming corrosion inhibitor utilizing nitrite, borate, azole. It helps keepsystems clean free from corrosive attack and harmful insulating deposits, thereby maintaining design heat transfer efficiencyand longer equipment life.The “D” v
3、ersion includes a special dye for early detection of problems such as leaks and acidity.The “E” version is formulated with Erythorbate to reduce ferric iron to ferrous iron.The “S” version does not contribute hydroxide to the final water, where high pH is not acceptable.BENEFITS Protects most metals
4、, including sweated copper lines, in chilled and hot water systems from corrosive attack Minimizes heat-absorbing sludge and mineral scale deposits in system Remains effective at temperatures of 300F and above Compatible with glycol-based antifreezes Helps extend equipment life Reduces maintenance t
5、ime and costs Superior corrosion inhibition due to synergy between nitrites and molybdate Does not affect non-metallic materials in cooling systemsAPPLICATIONSWET-4305 Series is a scale & corrosion inhibitor designed for HVAC closed loop systems. It is also used in systems thatcontain antifreeze (ei
6、ther automotive or HVAC grade), to provide additional protection against corrosion. Most antifreezeformulations, especially the automotive grades, do not contain sufficient buffer and corrosion inhibitor for HVACapplications. The addition of WET-4305 Series will increase the buffer and inhibitor lev
7、els to provide a greater protectionagainst corrosion.DOSAGE1.0 fl. oz. per gal yields 250 ppm nitrite as NO2 . To assure a clean system that is free of both corrosion and scale deposits,the following dosages are recommended.Chilled Water Systems: 1.5 fl. oz./galHot Water Systems: 3.0 fl. oz./galNote
8、: Dirty or contaminated systems should be drained, flushed, and chemically cleaned before treatment to get maximumresults. A side Stream Filter is highly recommended to ensure proper removal of loosened particles. A biocideprogram may also be necessary to remove any microbio contamination. Consult y
