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 NB Guard Scale Inhibitor DEWT is 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 Diesel NB Guard Scale Inhibitor DEWT 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.

Advantages:-1.Prolong the life of equipment by keeping scale and corrosion free. Since RXSOL-40-4002-025 Diesel NB Guard Scale Inhibitor DEWT 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 .
