Cooling Tower Chemical
An ecofriendly way to solve multiple problems of
cooling towers, heat exchangers, condensors, cold
storages, ice factories with a single chemical.
GRAMICID - C is a multi component product, which is
performing multiple functions at the same time.
The advantages are as follow:
Most Economical.
Biocidal, Fungicidal, Algaecidal & prevents
biofilming, due to Gramicid which used as a base in
the preparation of Gramicid - C.
Has killing action on protozoa.
Prevents Scaling & Fouling.
Prevents Biocorrosion and Chemical corrosion.
Good dispersant.
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.
Offers multi protection with a single chemical.
Universal use.
Totally ecofriendly & Biodegradable.

2. Economics
Increases the life of the equipment and saves
considerable amount of money by keeping the
equipment maintenance free for long periods.
Is most economical as compared to other products
available in the market as a single product is doing
multifunction.
The quantity required is at P. P. M. level hence
very economical.
Keeps the heat transfer surfaces clean & optimizes
heat transfer efficiency.
Brings the temperature down faster.
The antiscalant added in Gramicid - C prevents
scale formation for long time so also the anti
foulant of Gramicid - C helps in the water
remaining clear from fouling.
Shows a wide range of biocide activity both for
gram +ve as well as gram -ve bacteria.
Prevents sporogenesis, prevents yeast formation,
fungal growth, and algae growth.
Can be applied at temperature ranging from 0 oC to
95 oC, the efficiency increases at higher
temperatures. It can be also used in liquids
contaminated with organic matter.
It is tasteless & odour less when added to water.
Does not affect the pH of the treated water, in
effect it helps in maintaining the neutral pH.

Corrosion Prevention Chemical
Gramicid-25 is a combination of latest Antiscalent,
Dispersants & Corrosion Prevention Chemical Specially
formulated for Cooling tower water treatment.
The advantages are as follow:
Prevention of corrosion, Scales and non-biological
fouling by a single chemical.
Working as a water softening agent.
Most economical.
Affords multimetal protection.
Excellent control of carbonate, silicates, sulphate

3. & iron fouling.
Acid dosing is unnecessary in most instances as it is
effective over a wide pH range.
Keeps heat transfer surface clean & optimizes heat
transfer efficiency.
Contains no toxic chemicals and can be discharged
into effluent without any pollution problem.
Excellent thermal & hydrolytic stability.
Reacts with silica and ensures their removal during
blow down.
Disperses and removes old deposits of scales
gradually over a period of time.
Easy to handle being a liquid product.
Antiscalant & Corrosion Inhibitor for oil field water
treatment.
It’s also compatible with other oil field water
treatment chemicals.

Descalant Chemical
Gramicid-17 is a complex formulation of a 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
wide range of heating and cooling systems. It becomes
a versatile descaling agent which is safer still in terms
of equipment corrosion and safety of personnel.
Conventional descaling is a specialized job, it involves
considerable time, energy, money and expertise. The
descaling is done with acids like hydrochloric, the risk
involved in damage to equipment are considerable.
Personnel safety is also less. The inherent safety of
‘Gramicid - 17’ makes descaling a simple and routine
maintenance job.
The features of these are as follow:
Easy to handle
Harmless to equipment & personnel
Dissolves scales rapidly
Offers uniform descaling
Prolongs equipment life
Non-hazardous

4. Non inflammable
Does not pave the way for pitting corrosion
CONCENTRATION:
Gramicid- l7 is a powder, before use, it has to be
dissolved in water. An accurate estimate of the
quantity of Gramicid- l7required will depend on the
actual quantity of scale and the nature of scale that is
present in the equipment. A 3% - 10% w/w solution of
Gramicid- l7 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 for example scales found in sugar
evaporators, caustic evaporators in the aluminum
industry and black liquor evaporators in the pulp
industry.
