COOLING WATER TREAT
CORROSION INHIBITOR ( HIGH  NITRITE CONTENT)  RXSOL-40-4002-025 Powder (For Radiators, DG – sets, Closed Cooling System)

Introduction:-RXSOL-40-4002-025  is a  dry powder, nitrite/borate based compound with unique formulation with organic Corrosion Inhibitors , Anti-Scalant for use in closed cooling water systems , for preventing corrosion and scale Formation in Internal combustion engines, compressor cooling system, DG -set at high or low temperature. It is also acts as a corrosion inhibitor ( Protects all the metals including cast iron , mild steel , copper .)                                                                                                                                           

Note:-The stable oxide film that is formed by RXSOL-40-4002-025 prevents corrosion caused by electrolytic action between dissimilar   metals used in the system . RXSOL-40-4002-025 has been field tested and found to have no detrimental effects on non metallic substances such as seals, glands, packing, hoses, gaskets etc., normally used in these’systems

Application-DG*Sets:-Internal combustion engines closed circuit cooling system compressor cooling system. RXSOL-40-4002-025 incorporates superior corrosion inhibitors to prevent corrosion works by free of scale deposits.

Advantages:-1.Prolong the life of equipment by keeping scale and corrosion free. Since RXSOL-40-4002-025  is alkaline and so will suppress acid corrosion, which would otherwise result in corrosion damage such as pitting. However, the alkalinity control is such that even if the product is accidentally overdosed, the pH of the water will remain within limits. The metals which would be affected by extremes of alkalinity or acidity are protected.
2.Improves generating cooling efficiency by maintaining a clean heat transfer   
3.Corrosion protection by using superior corrosion inhibitor.
4.Reduced maintenance and down   time
5.Compatible with Coolants / Antifreeze solution / Glycol
6.Friendly with   Metals (Like steel, Copper, Aluminum, all alloys) & Non-metal (Rubber, Hoses, Gasket etc.)
Note:-In cases where systems are contaminated with oil and/or scale they should be cleaned before starting to apply RXSOL-40-4002-025 .There are suitable RX BRAND products to carry out the cleaning. Degreasing should be carried out using RXSOL SC 2002 and descaling by using RXSOL DC 1008 .

Specification                                                                                 Handling         

Method Of Use:-Properly   clean  the  system  with  water  and  alkaline  liquid ,  if  necessary. Add  0 .05-0.2 %  of  RXSOL-40-4002-025  in system or recommended Nitrite level1400 – 2500 ppm can be measured and controlled  by  any standard  RXSOL test  kit  for  Nitrite, Chloride  test  also helps  to detect excess  contamination  to  maintain  accepted  levels. when the product is dosed as recommended  limit By buffering action of   RXSOL-40-4002-025   , pHshould be maintained between 8.3 and 10 by the treatment.
Note:-Initial dosage for an untreated system is 2 Kg of RXSOL-40-4002-025 / 1000 litres of untreated distilled water. This will bring the treatment up to the minimum level of 1000 ppm nitrite.  For  best  result  and  prolonged  engine  life  add  RXSOL-40-4002-025 every  500 -6500  km. or  250  to  300 hours  of  running  time  or  every  2 month   interval.
