ROCCOR NB Corrosion Scale Inhibitor Liquid

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. 

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.

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 )

Dosage

Refer to technical datasheet.

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

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.

Industrial Usage

What is closed cooling system ?

The full closed cooling system is designed to circulate cooling water through the block and exhaust manifold.  water is circulated through water pump to heat exchanger tank and be pumped through many small tubes where it will exchange heat from the water of the circulating system. Then water exits the heat exchanger to go directly into the risers and then exit the boat. The exhaust manifold and riser will be blocked off, so no water will transfer between them. As for the circulating water in the closed cooling system, cool water will enter the engine through the circulating pump and circulate through the engine. The water will heat up in the engine and the warm water will exit at the water outlet on top of the manifold and head to the manifolds. After circulating through the manifolds, the hot water will head to the heat exchanger to exchange the heat it's carrying with the raw water. After the exchange the cool circulating water exits the heat exchanger and returns to circulating pump to begin another loop.

ROCCOR NB LIQ.
RXSOL-40-4001-025
Liquid (For Radiators, DG - sets, Closed Cooling and chiller System)
 
Introduction:-
RXSOL-40-4001-025 is a unique formulation with organic Corrosion Inhibitors , Anti-Scalant for use in closed cooling water systems , for preventing corrosion and scale Formation in Internal combustion engines, compressor cooling system, DG -set at high or low temperature.It is a concentrated liquid ,also used as a corrosion inhibitor ( Protects all the metals including cast iron , mild steel , copper .

Note:-The stable oxide film that is formed by RXSOL-40-4001-025 prevents corrosion caused by electrolytic action between dissimilar metals used in the system .RXSOL-40-4001-025 has been field tested and found to have no detrimental effects on non metallic substances such as seals, glands, packing, hoses, gaskets etc., normally used in these system .
 
Application - SDG*Sets:- Internal combustion engines closed circuit cooling system compressor cooling system RXSOL-40-4001-025 incorporates superior corrosion inhibitors to prevent corrosion works by free of scale deposits.
 
Advantages:-
1. Prolong the life of equipment by keeping scale and corrosion free. Since RXSOL-40-4001-025 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-40-4001-025 .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 .
 
Specification:-

Handling:- RXSOL-40-4001-025 is an alkaline product & should be handled like other chemical Avoid contact with Eyes, Skin ,in case of contact ,wash with copious amounts of water immediately.

Method Of Use:-
1. Properly clean the system with water and alkaline liquid , if necessary.
2. Add 0 .15-1.5 % of  RXSOL-40-4001-025  in system or recommended Nitrite level 1400 – 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 1. Properly clean the system with water and alkaline liquid , if necessary.
2. Add 0 .15-1.5 % of  RXSOL-40-4001-025  in system or recommended Nitrite level 1400 – 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-40-4001-025 , pH should be maintained between 8.3 and 10 by the treatment.

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 .pH should be maintained between 8.3 and 10 by the treatment.

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
