Safe Acid Descalex Liquid

RXSOL-54-1048-025  is mixed with fresh water 3 to 20 percent depending on deposition of scaling.

If the equipment to be cleaned is contaminated by oil, grease, sludge or carbonized oil, then first of all clean the system with degreaser  RXSOL-10-1005. RXSOL-54-1048-025 should be mixed with fresh water to form a solution of 10-30%, depending on the extent of scaling. After using RXSOL-54-1048-0250 ,  

PRECAUTION :::it is essential to thoroughly rinse all metal surfaces at least once with a 0.5% solution of  RXSO-20-2005  in fresh water. This solution should be circulated for 2-4 hours or until an acceptable pH value is obtained. This will neutralize any remaining acidity & passivate steel surfaces.


Procedure-of-use: The most effective descaling is accomplished by circulation.In the case of small components,the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease or sludge, then pre-cleaning with DEGREASER ( RXSOL OB 1005 ) is necessary. Depending on the extent of scaling, use a solution of 2.5-10% RXSOL-54-1008-025 . The solution will have a red colour which changes to orange when 85% of the acid has been neutralized , & to colourless  when the solution is totally neutralized. Whenever possible, the solution should be heated to 60°C.Neutralised  solutions can be re-activated by adding more RXSOL-54-1008-025  until the red colour reappears. This should not be done more than twice. RXSOL-54-1008-025  should not be used on Aluminium , Zinc, Tin or Galvanized surfaces.

Fields: Descaling of  Boilers, Descaling  of Diesel Engine Cooling Systems, Condenser, Pipeline collection system, Evaporators, Calorifiers, Heat Exchangers,The strength of the acid can be enhanced by adding 1part sodium chloride (common salt) to 20 parts of Descalex.If salt is not available, an acceptable alternative is to dissolve RXSOL-54-1008-025  in sea water. After use of RXSOL-54-1008-025  a  0.5% solution of Alkalinity Control in fresh  water should be used for neutralization.

After using  RXSOL-54-1048-025, sense all metal surfaces with 0.5 percent of  RXSOL-10-1005, at least 2-4 hour , up to neutral of PH value.

• Fast and effective scale remover.
• Soft on ferrous metals.
• Removes water scale & rust from boilers/diesel engine & other cooling system
• As well as from condensers, evaporators, & heat exchangers etc
 

Why Use RXSOL Descaler?

• It is a safe , economical concentrated  chemical to be used on the waterside of heat transfer equipment.
• You do not have to heat RXSOL-54-1048-025 .
  RXSOL-54-1048-025  is safer for the employees to use than other acid products.
• Your equipment will be cleaned in only hours without disassembling any part of the equipment. Equipment can also be cleaned without any down time (cleaning on the run).
•  Cleans down to the original surface without pitting.
•  RXSOL-54-1048-025 is safe on copper, copper-nickel, bronze, brass, iron, stainless steel and rubber.
•  RXSOL-54-1048-025  will extend the usable life of your equipment, especially when used as a part of a regularly scheduled preventative maintenance program.
•  Removing the scale build up allows your equipment to operate more efficiently with less down time.
