We produce and supply a wide range of Cooling tower biocide or open recirculating water biocides which are widely used for cleaning the closed loop systems to remove the microbial present in the water. The fouling present in the water obstruct the systems from proper functioning and working which can be removed by using these cleaners. Biological growth of algae, slimes and bacterial deposits prevent the normal functioning of the systems.

  Biocides function in the removal and prevention of spores, fungi, legionella pneumophila bacteria,   and many other bacteria etc in cooling tower water.

 
Cooling water biocide is very vital for healthy cooling water treatment for their following benefits:-

They avoid plugging of the nozzles with algae and biological foulants.
They prevent water borne life taking disease - legionella disease.
They improve heat loss because living organisms cause rise in water temperature.

 
Application:
Cooling Towers , evaporative condensers, cooling water heat exchangers, adiators, air washers, gear boxes, blow mouling machines, injection mouling machines, housings, d. G. Sets  etc.

Specification:
Form: Liquid / Solid
Specific Gravity: Variable
pH: Variable
Solubility: Completely/sparingly soluble in water

Dosage:
Cooling water biocides are normally fed to the re-circulating water by slug dosage directly to the ct sump (basin). The amount of to prevent or remove biofouling depends on the quality of feed water and plant operating conditions. The specific dosage rates will be specified by the csl technical representative.

 

Major Benefits:

Prevention of bio-fouling in system avoid plugging of nozzles avoids mic (microbiologically induced corrosion) prevent water borne disease improve the heat loss because living organisms cause rise in temperature of water.

Cleaning Chemicals play a vital role in making the machines and equipments to operate & function properly. Some major industrial coolant & heating machines & equipments go out of work due to the problems like dirt, dust, grease, oil and presence of inorganic and inorganic foulants. These problems are removed by using Chemtex’s offered range of cleaning chemicals while improving the efficiency and functionality of the machines. Due to small negligence and mistake cooling & heating equipments can get crash and be insensitive to work. We implement closed loop system maintenance which is a vital part of HVAC and ACnR maintenance program. this maintenance program can overcome the bigger loses like power loss, system efficiency loss, HTF (Heat Transfer Fluid) and Refrigerant fouling and degradation, loss of system life, un-scheduled maintenance jobs for de scaling and fixing leaks and bursts due to corrosion. The major area of Closed loop maintenance are being employed in Chemtex Speciality Limited which include Proper system cleaning & passivation after commissioning and corrosion Control. More detail information about above matter is available at www.chiller-chemicals.com.

Propylene glycol is used as antifreeze agent and industrial coolant in different industries where contamination with food is possible, de-icing solutions etc. Propylene glycol is generally regarded as safe for use in food. It is used in the industries like food, beverage etc for heat transfer, also used in vehicles. Antifreeze Coolant should be efficient in transferring the heat as well as preventing scale and corrosion.

Propylene glycol [HO-CH2-CH(OH)-CH3] is pronounced as pro'puh-leen-gly'col. It is a clear, colorless, slightly syrupy liquid at room temperature. The compound may exist in air in the vapor form though it must be heated or briskly shaken to produce a vapor. It is actually a multi-variant chemical compound. Propylene glycol - in an industrial cooling and heating process terminology is referred as industrial coolant or heat transfer fluid (HTF) or the common fluid that is used in large installations for transporting heat from one place to another.

Features :
  • serves as a solvent
  • offers outstanding stability with high flash and boiling points
  • reduces the freezing point
  • increases the boiling point
  • helps to bind and transport other substances (excipient)
  • holds and dissolves active ingredients equally in a medium
  • connects and stabilizes insoluble fluids (emulsifier)
  • attracts/holds water/moisture (hygroscopic)

Usage :
  • As an emulsification agent in Angostura and orange bitters
  • As a moisturizer in medicines, cosmetics, food, toothpaste, shampoo, mouth wash, hair care and tobacco products
  • As a carrier in fragrance oil
  • To produce polyester compounds
  • As a base in deicing solution
  • In smoke machines to make artificial smoke for use in firefighters' training and theatrical productions
  • As a solvent for food colors and flavorings
  • As an ingredient, along with wax and gelatin, in the production of paintballs
  • As a wetting agent, used to determine drying time in paints and coatings

A non-toxic substitute of Ethylene Glycol :

Propylene Glycol is the replacement of Ethylene Glycol in newer automotive antifreezes and de-icers in aircrafts. Like Ethylene Glycol, Propylene Glycol also has the special physical characteristics of depression of freezing point when mixed with water. It happens due to disruption of hydrogen bonding. Pure water freezes at 0OC. But aqueous solution of Propylene Glycol (10% by weight) has a freezing point of -3OC. 30% by weight aqueous solution of Propylene Glycol freezes at -12OC and a 60% by weight Propylene Glycol and water mixture can further lower down this freezing point to -51OC.

Why Glycol turned into red color ?

Because of the extensive corrosion & rust in the system metal makes the glycol turn reddish in color. At this point the glycol is fouled with iron contaminants that increase the glycol degradation rate. It is important to add corrosion inhibitor to the glycol system to avoid such degradation of glycol.

Application Areas :

Beverages & Juices, Breweries & Distilleries, Packaged Food Freezing, Canneries & Preservers, Fish Processing Units, Pharmaceutical & Bulk Drugs, Poultry Processing Industry, Thermal Storage System, Heating and Cooling Systems, Snow Melting and Refrigeration, Ice Skating Rinks, Vegetable Oil Industry, Ice Manufacturer, Cold Storage Systems etc.

Product Physio-Chemical Data :
  • Form and Appearance - Clear, colorless liquid
  • Assay as Propylene Glycol - 99.8%
  • Specific Gravity - 1.04 (approx.)
  • Molecular Wt. -  76.0548 gm/mol
  • Solubility in Water - 100%

Handling Measures, Precaution & Storage :

Propylene Glycol is slightly hygroscopic & the storage temperature is not critical, it must be stored under conditions so that contamination with water and adsorption of moisture are prevented. It should be noted however for product quality reasons the storage temperature should not go above 40°C. At below freezing temperatures the product viscosity might become too high for transfer from the storage containers with the pumps available. PG is a stable chemical and is not expected to deteriorate significantly with time provided if it is stored as indicated. The drums should be stored in dry condition, better to use the original drums rather than the other drums and if the drums are opened then it must be closed tightly at unused situation. The chemical can be stored up to 6 months.
