-
Quickly dissolves deposits containing carbon, resins or varnishes
-
Simple and economical to use by soaking or circulation method
-
Eliminates need for hard scraping
-
Can be recycled for future use
-
Non flammable
-
Low toxicity
-
Low evaporation rate
-
No phenols or chlorinated compounds.
Application
-
Removal of carbon type deposits from burner tips, fuel injectors and all components fouled by carbon, resin or varnishes
-
Cleaning oil side of fuel and lube-oil heaters, oil coolers etc
-
Removal of carbon based deposits from fuel and lube oil filters
-
Direct engine parts such as pistons, piston rings, valve spring, valve cages.
Dosage/User Instructions
Soak method: The items to be cleaned are dipped into the solvent, a wire basket can be used for small components. For removal of light deposits or oil, a dilution of up to 1:2 in fresh water may be used. Light deposits will be removed in 1 hour, whereas heavily oxidised deposits may need overnight soaking. After the components have been removed from the soaking bath, remaining solvent is easily removed with water.
Due to a very low evaporation rate, no precautions are necessary to prevent loss of liquid, but adequate ventilation is recommended.
Circulation: Where in-situ cleaning is required, the chemical can be used neat and circulated through the unit in question. Time required for this process will again depend on extent of fouling and may take up to 20 hours.
-
Before circulation with the cleaner blow compressed air or steam through the system to begin with, to remove as much as possible of the residual oil.
-
Connect up the end of the oil system to a pump, fill the system with the cleaner and circulate.
-
Continue circulating through the system for 4 to 24 hours. Cleaning process will depend on the type of deposits involved.
-
Heating the cleaner will enhance the effectiveness, but temperature should not exceed 60oC.
-
When cleaning is completed, drain out the cleaning solution and flush the system with a petroleum solvent such as gas oil or kerosene.
AIR COOLER CLEANER
Uses/Benefits
-
Fouling of air coolers is reduced thus heat transfer and engine efficiency is improved.
-
Fire hazards from the build up of grease and residues are minimised.
-
Down time and expense of periodic dismantling of the air handling system for cleaning is eliminated.
-
Scavenging efficiency is improved by the reduction of deposit build-up around scavenging ports.
-
Water displacing surfactants incorporated in the chemical form a mono molecular film throughout the air handling system, which protects the metals and reduces the adherence of airborne contaminants.
Application
-
In service cleaning of diesel engine air coolers and scavenge trunk systems.
-
For use in soak baths, immersion cleaning systems.
-
Light carbon removal from machinery parts.
Dosage/User Instructions
Aquamarine Carbon Remover combined Air Cooler Cleaner is suitable for all types of diesel engine. The cleaner/fresh water mixture has no flash point and cylinder lubrication is not impaired.
The following table shows our recommendation for initial dosage per air cooler. This is based on one injection every 24 hours. This can be varied based on performance of the pressure drops across the air coolers.
| ENGINE PERFORMANCE | DOSAGE PER 24 HOURS | |
| Concentrate | Cleaner/Water mixture | |
| 5000 - 10000 H.P. | 1.0 litre | 3.0 litres |
| 10000 - 25000 H.P. | 1.5 litres | 4.5 litres |
| OVER 25000 H.P. | 2.0 litres | 6.0 litres |
Product can be applied by injection, immersion or circulation. For immersion and circulation, cleaning time is reduced considerably by heating the chemical to maximum 50oC. If the air coolers are very dirty it may be advisable to use Aquamarine Aquawash to thoroughly clean the system before commencing the injection treatment.
Immersion method: The dismantled parts to be cleaned are laid in a tank specially designed for the purpose and been filled with the cleaning chemical. Movement is achieved by means of compressed air. Cleaning time is estimated to take from 5 - 12 hours.
Circulation method: The equipment to be cleaned like fuel oil pre-heater, oil cooler etc is connected to a pump and a tank by means of tubes. Depending on the degree of fouling, the cleaner is circulated through the equipment for 5 - 15 hours.
Injection method: By means of a special injection system a mixture of the chemical and fresh water in a ratio of 1:2 (observe the mixture ratio exactly) is injected into the air channel between the turbo blower and the air cooler. This is followed by a second injection of fresh water only.
