Cleaner 535 is a highly concentrated tank cleaner based on petroleum solvents,emulsifying agent and surfactants.
A : Cleaning / Degreasing of Boilers
1) Find the source of contamination and rectify this problem before starting the cleaning operation.
2) The degree of oil contamination will determine the required solution strength Between2-20% of cleaner 535 in water is suggested. For heavy contamination ,up to a 20 % solution may be required , e.g 2% solution is 20 litres per 1000 litres water
3) Dose the required amount of cleaner 535 through the steam drum manhole. Re-secure steam drum manhole cover.Open vent valve on steam drum .Fill the boiler with water to working level.
4) Boiler can now be fired for about 4 minutes and then shut down for 10-20 minutes Keep repeating this process until the solution has reached a temperature of 50 - 60ْC continue this operation for 12-18 hours, maintaining the solution at 50 - 60ْ C which will promote agitation and circulation of liquid to give better cleaning efficiency.
5) Drain boiler ,then open manhole covers. Use a high pressure hose to flush drums ,tubes and headers , starting at the top. After flushing boiler ,secure and refill.
B : Degreasing Marine Diesel Engine Cooling Water Systems .
( This method may be applied when engine is out of service )
1) Drain the cooling system and flush with water.
2) Calculate the amount of cleaner required for a solution strength of 2% ( 20 litres per 1000 litres cooling water).
3) Refill engine with water adding cleaner 535 .
4) Circulate the solution through the system and heat until the water reaches a temperature of about 60 C.
5) Continue circulation of the solution through the system for a minimum of 5 hours.
6) Drain engine and check the result of the cleaning operation. Repeat cleaning procedure if necessary.
7) When cleaning is completed ,drain the system , and thoroughly flush with clean water.Refill while adding an anti -corrosion treatment such as DM-130 OR DM-125
