Product Description:

COOLING WATER CORROSION & SCALE INHIBITOR
Corrosion Inhibitor for Water Systems  having  unique formulation with highly concentrated liquid cooling treatment compound, ferrous & Non ferrous corrosion inhibitors, antiscalants, dispersant and buffer solution of non carbonate. Usefull for use in high or low temperature closed cooling water systems for the prevention of corrosion and scale formation in internal combustion engines, compressors, chiller system and DG sets. Protects all metals including cast iron, mild steels and copper. Recommended ppm levels are easily controlled by standered RXSOL test kit Nitrite / Chloride.


The stable protective microfilm prevents corrosion caused by electrolytic action and the alkaline nature of this product prevents acid attack.

The stability of the added polymers are very useful for water treatment processes. Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide. 

Product Application:

Prolongs the life of equipment by keeping it scale and corrosion free. Since RXSOL-40-4001-025 is alkaline, it will suppress acid corrosion, which would otherwise result in sever pittings. It improves cooling efficiency by maintaining clean heat transfer surfaces , from Radiators, DG - sets, Closed Cooling and chiller System.

FIELDS ::: --- Suitable for use in closed water cooling systems, ice melting systems and transformer cooling systems. The product may be used in all kinds of diesel & petrol engines, compressor or heating cooling water circuits.


( Used as a corrosion inhibitor for all ferrous and non-ferrous metals found in water systems )

 
 


 

Product Dose:

Refer to technical datasheet.

GENERAL RECOMMENDATION : ( The dosage chart may be used as a guide to adjust treatment to obtain the optimum level.)

Nitrite (as PPM NO2) 0  100-200 300-600 700-900 1100-1300   
RXSOL-40-4001-025 / 1000L 8.0  7.3 7-8 5-7   1.5-3.5

NOTE ::: --   If nitrite level becomes 1440-2400 then doses should be ZERO.


The initial dosage for an untreated system is 8 liters of product per 1000 liters of water. Such a dose will bring nitrite levels over 1200 ppm. Maximum nitrite level is considered to be 2400 ppm. Frequent tests should be carried out in order to maintain pH values within the limit (8.3-10.0), while levels of chloride should be maximum 50 ppm.
 

Product Note:

Initial dosage for an untreated system is 9 litres of RXSOL-40-4001-025 / 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-40-4001-025 every 500 -6500 km. or 250 to 300 hours of running time or every 2 month interval. Specially designed for use in  water systems of internal combustion equipment. pH should be maintained between 8.3 and 10 by the treatment.

RXSOL-40-4001-025 will react with sludge and in most cases, facilitate sludge gradual removal. On badly fouled systems with oil or scale, a prior degreasing by using DEGREASER HEAVY DUTY or descaling by using DEGREASER HEAVY DUTY, SCALE REMOVER LIQUID or SCALE REMOVER POWDER is highly recommended.

Product Technical Specification:

RX MARINE INTERNATIONAL are continiously working in water treatement sector, And developed many unique product to avoid corrosion and scale depositon in cooling water system. Here I wants to keep our experiment results with you.Corrosion inhibitor for closed cooling systems containing molybdate/phosphonate ( RXSOL-40-4018-025 ). Sodium molybdate has the advantage in that the dosing of lower ppm's of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition that sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.

Remarks:

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

Product Supply Location:
During Circulation of water mainly controlling of 2 factors required : -
 
SCALE CONTROL in closed water cooling systems - Diesel and gas engines releasing high temperature due to that water present in jacket cooling system  increases its tendency to deposit scale. To avoid scale formation water softener like Zeolite  gradual buildup of scale in cylinders and cylinder heads. Where condensate is available, it is preferred for closed system cooling water makeup. Where condensate is not available, zeolite softening should be applied to the makeup water.
 
CORROSION CONTROL An increase in water temperature causes an increase in corrosion. At high temperature  solubility of oxygen in water decreases due to that Corrosion rates increasing inside the system.  This occurs because the lower solubility of oxygen with increasing temperatures in a freely vented system decreases the corrosion rate faster than the rise in temperature increases it. However, in many closed systems, the dissolved oxygen entering the system in the makeup water cannot be freely vented, resulting in the release of oxygen at points of high heat transfer, which may cause severe corrosion. Untreated systems can suffer serious corrosion damage from oxygen pitting, galvanic action, and crevice attack. Closed cooling systems that are shut down periodically are subjected to water temperatures that may vary from ambient to 180°F (82°C) or higher. During shutdown, oxygen can enter the water until its saturation limit is reached. When the system is returned to high-temperature operation, oxygen solubility drops and the released oxygen attacks metal surfaces. 
 
The three most reliable corrosion inhibitors for closed cooling water systems are chromate, molybdate, and nitrite materials. Generally, the chromate or molybdate types have proven to be superior treatments.
