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.

Application:

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%u2019 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. hours> 4. Re check the readings. and record. 5 track these readings

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-Algaecide
