SCALE B-30

 



SCALE B-30


In hard water areas, the use of water in heating and cooling systems invariably results in a build up of limescale (hard water) deposits within the system, usually in the highest temperature zones.

The resultant scale not only restricts water flow, but acts a very effective insulation, reducing heat transfer efficiency, and increasing running costs. Heavy scale deposits can also lead to localized overheating of heat transfer surfaces, resulting in premature failure of heating appliances.

In all areas, rust and corrosion may take place in heating and cooling systems, leading to a build up of corrosion deposits, and a reduction in efficiency.

 

DESCRIPTION

 

ScaleB-30 is a powerful & economic liquid for use in cleaning heavily scaled equipment, where speed and high solvency are critical. Rapidly dissolves limescale and rust. Contains wetting agents to penetrate heavy deposits. Safe to use with steel cast iron, copper, brass and most plastics. Scale B-30 formulated form a blend of acid, corrosion inhibitors designed to quickly remove calcium carbonate/ magnesium scale (limescale) from cooling tower surfaces. Scale B-30 contains corrosion inhibitors specifically designed to prevent acid attack on steel, iron, metal such as copper etc., which are commonly used in the today’s Cooling Towers.


PRODUCT BENEFITS


Highly effective and absolutely safe product, react only with scale
build-up an does not react with metal at  all. Inhibiting effect  
remain stable even at  high temperature i.e. 70 to 80 degree celcius

Remove rust deposits and prevent re- rusting.

Dissolves film of oil or grease  present in the deposits.

Quickly penetrates, disintegrates and dissolves hard scale deposit in Un- accessible passages.

                          
Contains a synthetic polymeric corrosion inhibitor which forms a 

Protective film on parent  metal  surface preventing  metal  against
acid attak.

A powerful liquid multi- purpose descaling compound  which breaks
and dissolves hard scale including silica scale.              

It is a blend of suitable acids  ( Organic & Inorganic ),  
Corrosion inhibitor, penetrants, Surfactants & additives e.t.c.




Where it is used:

The function of a Cooling Tower is to remove heat from the cooling system water after the water has picked up heat while passing through the water-cooled condenser. The heated water from the water-cooled condenser/ heat exchanger is then broken up into droplets by circulating the water over the tower fill inside the cooling tower. The forced drought within the tower causes ambient air to pass through the water where a portion of the water is evaporated thereby reducing the temperature of the water by 7-10*F. The cooled water is then forced by the re-circulating pump back through the condenser/heat exchanger where the process is again repeated.

Scale builds up in the condenser/heat exchanger tower due to the over-concentration of the mineral content of the system water. This over-concentration of minerals can be caused by the lack of controlled bleed off.

If there is no bleed-off in a system the mineral content will over-concentrate due to :

The introduction of untreated make-up water to the system, which adds solids to the system water.

Water is constantly being lost to the system due to both evaporation and windage. The lost water is automatically replaced in the cooling tower by the automatic float assembly in the cooling tower which will introduce fresh make-up water as soon as the water falls below a set level in the tower. Neither chemicals nor minerals are lost to the system through evaporation. Therefore, if there is no bleed-off, neither chemicals or mineral levels can be controlled within the system,  and  scale growth will occur.



How it is used:


Calcium/magnesium scale can easily be removed from the system by applying Scale B 30 to the system sump at a rate of 15 kg of Scale B-30 for every 100 ltr of system water. Initially flush the system with clean water to remove any loose contamination. Then refill the system and apply scale remover as noted. Operate system for 30 minutes to 2 hours or until head pressure returns to normal. Circulate the solution until all the scale is dissolved.  If head pressure does not return to normal or if scale is still present, repeat treatment. After cleaning, drain and rinse the system thoroughly using an alkaline solution to neutralize the system (CV-Passivator recommended).

 

Important:  The water temperature in the cooling tower must be in excess of 80*F to insure that the      Scale B-30 will react with the scale deposits in the tower.

 

Direct/Indirect Losses Due To Substandard Descalant


·        Metal loss due to poor inhibitor quality.

·       Corrosion of costly equipment.

·        Uneven or incomplete Scale removal.

·       Non removal of Scale in inaccessible passages bends and corners.

·       Loss of energy/production even after descaling due to poor descants

·      Accidents.


 


Features, Benefits & Applications


·         Fast and effective scale remover

·        Acid based product that contains inhibitors against attack on ferrous metals

·     Removes scale and rust from condensers, evaporators, heat exchangers, etc.


Cautionary Guidance


Irritant to eyes, respiratory system and skin.

 Eye contact: In case of contact with eyes, immediately flush for at least 15 minutes with plenty of water. Seek medical advice.

 Skin contact: Wash affected area thoroughly with water. In case any irritation persists, discontinue use of the product and seek medical advice.

 Ingestion: In case of ingestion, drink water to dilute the product. Do not induce vomiting. Act immediately to prevent further irritation. Seek medical advice.

 Inhalation: If irritation should occur, rinse mouth and throat with water and move to fresh air. If any irritation persists or asthma-like symptoms occur, seek medical advice.

 


Storage requirements:

 

Provide sufficient ventilation. Store in a cool and dry area.

Information for safe handling: Keep receptacles tightly sealed. Store in original container. Store below 40° C. Avoid extreme temperatures.

Do not leave the product in the system longer than necessary. Be certain that persons handling Scale B-30 have aprons, rubber gloves, and safety glasses. Avoid skin and eye contact. A safety shower or an available source of fresh water nearby is recommended in case of skin contact

 

Handling:

 

Scale B-30 should be handled with care, wear goggles, and protective clothing to protect eyes and skin.


To determine the amount of bleed-off required and to prevent the condenser/heat exchange from Scaling it is necessary to determine the “Cycles of Concentration”. This is the number of times system water can be concentrated in comparison to the make-up water before the system water starts to over-concentrate and begins to form scale. The chloride ion is stable and can not be chemically altered - it can only be increased or decreased by the “Cycles of Concentration”.

Cycles of Concentration is defined as the number of times a molecule of water is rotated in the condenser system, before it is blown down, or carried away as drift, or boiled through process of evaporation. Analytically, it is the ratio of the sum of water evaporated, water lost due to drift, and waters blown down to the sum of water blown down and drift loss. C = {E/(B+D)}+1. E and D are constant and B is the only variable component. Higher the value of C, lower is the volume of water blown down. Drift is also a form of blow down, except it is uncontrolled.
