BUSOL DIESEL ENGINE COOLANT TREATMENT
Busol Diesel Engine Coolant Treatment 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 systems.
The compound 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.
In cases where system are contamined with oil and/or scale they should be cleaned before starting to apply Busol Diesel Engine Coolant Treatment. There are suitable Busol products to carry out the cleaning. Degreasing should be carried out using Tankleen Plus and descaling by using Descalex. Ref. Busol Water Treatment handbook.
The use of antifreeze is sometimes required if the vessel is to be laid up in cold areas and so Busol Diesel Engine Coolant Treatment can be used in conjunction with antifreeze products.
If the system contains galvanized parts, it is advisory to clean the system with Descalex prior to commencing the treatment.
Sampling and Testing
Use the dosage chart overleaf to adjust the treatment to obtain the optimum level. It is important that at least weekly testing is carried out to ensure levels of treatment are correct.
The dosage chart given below is for convenience in calculating the amount of Busol Diesel Engine Coolant Treatment required to bring the treatment level to the suitable point between the minimum and maximum – this being 1440 ppm nitrite.
Normal nitrite limits: 1000-2400 ppm nitrite (NO2)
N.B. Buffering agents in Busol Diesel Engine Coolant Treatment maintain pH values within suitable limits when the product is dosed as recommended. Normal pH should be maintained between 8.3 and 10 by the treatment.
The engine manufacturer’s recommendations for water quality should always be complied with. Chloride levels should be as low as possible. Most engine manufacturers recommended a maximum of 50 ppm chlorides.
