Engine Water Treatment Chemicals Powder for Diesel Engine, RXSOL-40-4002-025 is a dry powder, Nitrite / Borate based compound with unique formulation with organic corrosion inhibitors and anti-scalants for use in closed cooling water systems.
Diesel Engine Water Treatment - DEWT Scale Guard NB is a non-chromate powdered product incorporated with corrosion inhibitors specially designed to inhibit and prevent corrosion in diesel cooling waters systems
Engine Scale Guard DEWT Guard NB Prevents corrosion and scale formation in closed cooling water systems of internal combustion engines, compressors, diesel generators. Used as a cooling water additive for ships’ diesel engines
Dry powder with Unique formulation with organic corrosion inhibitors and Anti-Scalants for use in closed Engine cooling water systems.
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.
