Soaked method
This method is an effective way of cleaning deposits from machine parts. 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 can 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 flushed off with water.
Due to a very low evaporation rate, no precautions are necessary to prevent loss of liquid, but adequate ventilation is recommended.
Cleaning the Oil Side of Heat Exchangers
Where in-situ cleaning is required, Carbonclean LT 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 24 hours.
The Unitor Chemical Cleaning Unit - Product no. 664 613807 - is recommended to be used.
- Disconnect the heat exchanger's oil inlet and outlet, drain off any remaining oil.
- Connect the discharge side of the Chemical Cleaning Unit (CCU) to the lower heat exchanger connection and fit the return to the CCU.
- Add Carbonclean LT to the drum and heat, maintaining the temperature (max 60°C), throughout the cleaning operation. If heat is not available the cleaning time will need to be extended.
- Circulate for 12 hours. When the cleaning is complete, disconnect the lower heat exchange connection and drain out the cleaning solution.
- Connect a fresh water supply to the upper heat exchanger connection. Rinse until water runs clear.
- Disconnect the water supply, drain and dry the heat exchanger.
The Unitor Chemical Cleaning Unit can also be used for cleaning by soaking or circulation. Results can be achieved with maximum efficiency and with the minimum use of Carbonclean LT.
