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.
A non-chromate powdered product incorporated with corrosion inhibitors specially designed to inhibit and prevent corrosion in diesel cooling waters systems.
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.
Before testing of Nitrite level, Here is some point and guideline, what you need to do. : 1 take the following readings; pH, TDS (uS), and nitrite level.and record. 2 add the Chemical your are using. 3. wait for a period of time for the sysem to circulate.
for a period of time.
If the TDS and Nitrite drop you have a leak/ unknown makeup. if the TDS stays stable and the nitrite drops you have a biological problem. Bacteria that convert nitrite to nitrate.
Solution ::: Use DI water in place of general water, And also use. Algaecide to control Bacterial growth inside water system ... http://rxmarine.com/Biocide-
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.
