‘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 life

Quasil-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 a small 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 the equipment 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

Arrangements For Descaling Operation: Circulation of the descaling solution is recommended. Connect the tank containing the descaling solution to the equipment to be descaled by means of pipes or rubber hoses.The solution should preferably enter at the lowest point of the equipment and leave from the highest point. Thiswill prevent formation of gas pockets and subsequent uneven descaling. Circulation may be effected through amechanized pump or a hand pump. If however, where circulation is difficult, the equipment to be descaledshould be filled with 3% to 10% solution and allowed to soak for 8 hours.

Checking For Completion Of Descaling: A sample of the descaling solution may be withdrawn periodically and tested for acidity either by titration or byusing a pH paper. When descaling is complete the concentration of acid will remain constant. If however, thesolution shows no acidity more QUASIL-D should be added to the descaling solution and the process of descalingcontinued till the constancy of concentration of acid is achieved.

Flushing & Neutralizing: After completion of descaling drain the equipment and flush thoroughly with water till water becomes neutral.
Handling: Though it far safer than conventional descaling compounds, the following precautions must be taken whilehandling QUASIL-D Avoid prolonged inhalation of the vapour.  Avoid contact with the concentrated solution with skin over a long period.  In case of accidental contact with the eyes wash with water for 10 to 15 minutes and obtain medicalattention if required.

An Ecofriendly Way To Solve Multiple Problems Of Cooling Towers, Heat Exchangers, Condensers, Cold Storage, Ice Factories With A Single Chemical.
QUASIL-B is an oxidising multi component Biocide product, which is performing multiple functions at the same time.

Advantages :-
  • Most Economical
  • Biocidal, Fungicidal, Algaecidal & prevents biofilming.
  • Has killing action on protozoa.
  • Prevents Scaling & Fouling.
  • Prevents Biocorrosion and Chemical corrosion.
  • Good disparsant.
  • Can be used in all conditions & convenient to handle. Even accidentally excessive quantities do not harm the system.
  • Reduces power consumption by increasing efficiency of the system.
  • No need to use acid to bring down the pH to neutral level. 
  • Reduces the plant shut down time.

Dosages: The dosages of QUASIL-B will depend on the following information to give an exact dosage, the following particulars are needed. Quantity & Nature of bacteria. Nature Of Algae & Fungi. Temperature of water. pH Value. Surface material & its composition. Total water hardness & Questionnaire. If this information is not available, then as guide the following dosages are recommended, the quantities refer to the volume of circulating water. Initial dose 200 ppm. as shock dose then a maintenance dose 100 ppm. 3 times in week.


Safety Manual: QUASIL-B is non toxic, however in its concentrated state it does have an irritable & bleaching effect on the skin, on mucous membranes and respiratory tracts and is thus particularly harmful to the eyes. When working with QUASIL-B protective goggles should be used. Usage of rubber gloves is advisable which can be rinsed after usage.

Economics Of Quasil-B:
  • QUASIL-B - Increases the life of the equipment and saves considerable amount of money by keeping the equipment maintenance free for long periods.
  • QUASIL-B - Is most economical as compared to other product available in the market as a single product is doing multifunctions. QUASIL-B - The quantity required is at P. P. M. level hence very economical.
  • QUASIL-B - Keeps the heat transfer surfaces clean & optimizes heat transfer efficiency. QUASIL-B - brings the temperature down faster.
  • QUASIL-B - The antiscalant added in QUAASIL-B prevents scale formation for long time so also the anti foulant of QUASIL-B helps in the water remaining clear from fouling.
  • QUASIL-B -shows a wide range of biocidal activity both for gram +ve as well as gram -ve bacteria.
  • QUASIL-B -prevents sporogenesis, prevents yeast formation, fungal growth, and algae growth.
  • QUASIL-B - can be applied at temperature ranging from 0oC to 95oC, the efficiency increases at higher temperatures. It can be also used in liquids contaminated with organic matter.

Taste & Odour: It is tasteless & odour less when added to water.

pH Neutrality: QUASIL-B does not affect the pH of the treated water, in effect it helps in maintaining the neutral pH.
