Quasil-D’ is complex formulation of a powerful descaling agent, a surfactant and corrosion inhibitor compound.It is ideally suited for removal of scales from Cooling Towers, Boilers, Coils, Heat exchangers, Chillers and a widerange of heating and cooling systems. It is particularly effective in removing the problem of milk stones in MilkIndustry.‘Quasil-D’ becomes a versatile descaling agent which is safer still in terms of equipment corrosion and safety ofpersonnel.Conventional descaling is a specialized job involving considerable time, energy, money and expertise. Whendescaling is done with acids like hydrochloric, the risks involved in damage to equipment are considerable.Personnel safety is also less. The inherent safety of ‘QUASIL-D’ makes descaling a simple and routinemaintenance job.QUASIL-D: Is easy to handle, Is harmless to equipment & personnel Dissolves scales rapidly Offers uniform descaling Prolongs equipment lifeQuasil-D though acidic, is non-hazardous, non inflammable and unlike HCL does not pave the way for pitting corrosion.

METHOD OF USE FOR SCALE TESTING:Wherever possible, a small indicative test should be carried out before using,Quasil-D. A strong solution should be prepared by dissolving a few grams of Quasil-D in a little water and asmall quantity of the scale scrapped off the equipment to be descaled should be placed in it, if effervescence isnoted, it may be concluded that Quasil-D will act quickly and efficiently.CONCENTRATION:Quasil-D is a powder, before use, it has to be dissolved in water. An accurate estimate of the quantity of QuasilD required will depend on the actual quantity of scale and the nature of scale that is present in the equipment. A3% - 10% w/w solution of Quasil-D in water is generally recommended.The total quantity of this 3% to 10% descaling solution will be about 10% higher than the filled volume of theequipment to be descaled.This formulation is recommended for scales containing high silica. Typical examples are scales found in sugarevaporators, caustic evaporators in the aluminum industry and black liquor evaporators in the pulp industry
