ICI - 716, 717 (I), 717 (II)
Corrosion Inhibitors
Closed cooling
system can be categorized into three categories: -
1. SUB-ZERO: - These systems operate in the range of 0 to 20 0C and
less. Here glycol or calcium chloride brines are used as cooling
medium in closed loop. Typical example is ice factories, where brine
solution is used for cooling the water in the ice moulds.
2. LOW TEMPERATURE: - Here the temperature of cooled water is in the
range of 40 to 70C and the returned water temperature is around 80 to
130C. Typical application is air conditioning where chilled water goes
to air handling units where hot air blown over this is cooled and warm
water comes back to chiller for cooling again. Raw water/ Soft water
is used as make up.
3. HIGH TEMPERATURE: - Here the water in closed loop is used for
cooling molten material like steel, glass, plastics, aluminum where
they are being reformed either by extrusion or by casting in moulds
etc. As the temperature of these materials in molten stage is quite
high, higher purity water is essential for cooling them as in these
ultra high temperature (1200 0 to 1300 0C), slightest presence of
CaCO3 etc. can lead to scaling. So usually, Soft/DM Water is used for
this application. Application such as automobile radiator and internal
circuit of D.G. Sets using Glycol/CaCl2/NaCl brine should also use DM
water for cooling.
PROBLEMS: - Corrosion, Bio-fouling
and Fouling (due to corrosion products and bio-fouling) are the major
problems in a closed cooling system. In high temperature system if
water quality is not good then scaling may also occur.
SOLUTION: - To keep pace with time
and technology, close water circulating systems demand efficient and
cost effective corrosion inhibitors.
BENEFITS OF CORROSION INHIBITOR
• Readily miscible with water which accelerates working efficiency.
• Doesn’t contain chromate thus causes no pollution and environment
friendly.
• Cost effective and even small concentration exhibits desired
results.
CLEANING: - Before start of the
treatment, closed cooling system should be cleaned ON-LINE/ OFF-LINE.
Special efforts must be made to remove as much iron as possible (which
is present due to formation of corrosion product) preventive treatment
should follow cleaning immediately to prevent fresh cleaning.
Our Products
ICI-716, ICI-717(I) & ICI-717(II) are chemicals that offer
comprehensive and result-oriented treatment in order to control these
problems consequently & users can achieve the maximum result from the
closed Systems.
Product is based upon a combination of anodic and cathodic corrosion
inhibitors. It increases solubility of calcium and magnesium salts in
the water, and protect lining against corrosion & pitting.
PRODUCT BENEFITS
ICI-716, ICI-717(I) & ICI-717(II) products have been specially
formulated to prevent corrosion in closed system. They provide
following benefits.
* Specially formulated to disperse the soluble ions in circulating
water, thus, no precipitation takes place.
* Superior steel corrosion inhibition under wide range of pH and
alkalinity fluctuations.
* Formulated as per your water parameters.
* Doesn’t contain chrome or heavy metals, which are harmful effluent
thus environmental friendly.
* Active ingredient works at lowers dosage.
* Prevents fouling due to presence of special dispersant.
Dosage & Feeding
The water holding volume of system, quality of water and other
relevant factors determines dosage. We will provide technical
assistance and will suggest particular product, its dosage, in
accordance with your plant operating conditions and quality of water.
Handling
Avoid contact with skin, eyes & cloths. In case of contact, wash with
plenty of water.
Packing
50 & 200 Ltrs. HDPE Containers.
