COOLING WATER
TREATMENT CHEMICALS |
Used by various sectors like power generation,
Petrochemicals, Fertilizers & Refineries, Locomotives
/ Automobiles, etc. |
| |

|
ANTISCALENT &
DISPERSANT – a specially designed unique
formulation for scale inhibition. It is a
powerful dispersant & antiscalant agent
especially customised for the control of scale,
deposition & fouling in recirculating cooling
water system. It has a very strong dispersing
ability that enables the easy dispersion of
insoluble particulate matter like clay, mud,
silt, etc. and prevents their accumulation in
low velocity areas. It effectively prevents Ca,
Mg & Zn phosphate scales. |
 |
CORROSION &
SCALE INHIBITOR - a specially designed
unique formulation for corrosion & scale
inhibition. It is a blend of cathodic & anodic
inhibitors to controls corrosion of multi-metals
in cooling water systems. It also eliminates
scale formation on heat transfer surfaces of
cooling water system due to the combined effect
of antiscalant & powerful dispersant. |
 |
BIODISPERSANT – a specially formulated
product to control slime formation on surfaces
of cooling water cooling water system and to
optimize heat transfer capacity by keeping the
heat transfer surfaces clean. It contains
non-ionic surfactants alongwith solubilizing &
penetrating agents. It improves the performance
of chlorine & non-oxidizing biocides by removing
and dispersing slime & deposits thereby exposing
trapped microorganisms. It is non-toxic &
non-polluting and also has no chlorine demand.
|

|
BIOCIDE –
A range of biocides to control microbial growth
observed in the cooling water system. It is a
wide spectrum biocide to be used to control
algal, bacterial and fungal growth in cooling
water systems. It also controls Anaerobic
bacteria like Sulphate reducing bacteria, etc. |
 |
 |
POLYMER –
It is based on organic polymer for nil phosphate
system designed to eliminate scale formation on
the heat transfer surfaces under cooling water
conditions. It also contains powerful deposit
controller which disperses suspended matter and
is removed during normal blowdown. |
 |
CORROSION
INHIBITOR FOR CLOSE LOOP CIRCUIT - It is
available in borate nitrate based & borate free
formulation for the closed loop systems. It is
specially formulated with new generation
chemicals to control corrosion of multimetal
systems. It also contains low molecular weight,
multifunctional polycarbonxylates alongwith
organic antiscalent to efficiently control
corrosion and scale deposits on heat transfer
surfaces. |
