_ Glycol Brine in an industrial cooling and heating process terminology is referred as coolant or heat transfer fluid(HTF) or the common fluid that is used in large installations for transporting heat from one place to another. Chiller Circuit Glycol Brine is used for lowering the freezing point and enhancing the heat transfer efficiency.


Glycol Brine Solutions are of various 3 types used in today's world for heat transfer & thermal storage, such as Glycol based brine such as mono ethylene glycol (MEG), propylene glycol (PG) and diethylene glycol (DEG). Inhibited Brine solutions of these brine solutions are also available that provides protection of metal against crevice and cavitation corrosion.

Brine or glycol coloring agent is a unique leak detecting instrument that is very easy and economical to use. Small amount of ALSTA GLO added to the system turns the whole glycol, brine or coolant solution to turn bright florescent green color. This color is unique in the way that it starts glowing in presence of UV light.

Now have comes two questions in mind - Why? And How? Especially when Propylene Glycol or Inhibited Propylene Glycol is used as heat transfer agent in food, beverage or brewery industries, there lays a possibility of contamination even though Propylene Glycol is harmless to our health up to a certain level. But to keep ourselves on the safer side of the problem, something has to be done to detect the leakage of Glycol from the system. But we are fortunate enough that it had already done. Chemtex’s continuous innovation blesses us with a perfect blend of Inhibited Mono Ethylene Glycol or Inhibited Propylene Glycol and a colored leak detecting media. This media turns the Glycol solution to fluorescent green or orange colored solution. So, whenever there is any leakage from Glycol systems, it will be visible during the daylight and even in the night time due to its fluorescent color.

The leak detection dye also has a very special feature that can make it very easy to detect small pinhole punctures or leakages at its very nascent stage before it takes a shape of a large puncture or burst and cause production and maintenance havoc. This special mechanism of the Brine leak detection dye is its ability to glow in the dark in presence of UV light. However, the bright green or orange color of colored Glycol remains easily detectable whenever or wherever there is a leakage and thus helps us to avoid unwanted contamination of Ethylene or Propylene Glycol especially with food items and other chemicals used in the system.

               At the last but not the least we can conclude with this belief that Chemtex is one of the leading international ISO 9001:2008 certified companies which provides its clients Inhibited Ethylene Glycol and Inhibited Propylene Glycol over the last few decades and will continue in near future. 

Inhibited Propylene Glycol is used in chillers, glycol systems, boiler systems, solar panels, and many other water based systems. It is usually produced from either propylene oxide or glycerol. For Chemtex’s Inhibited Propylene Glycol contact us at +91-33-7111-1111 or [email protected]

ALSTASHINE - Coil Cleaner is a non-acid liquid cleaner & brightener for complete removal of dirt, dust, greasy & oily soils, carbon deposits & grime on the aluminum fins & copper coils of AHU, FCU, Air Conditioners, Car Condenser and Radiator (external), Air Cooled Chillers, Air Cooled Condensers, Air Cooler Tube Bundle etc. It is easily used manually with normal, hydraulic or atomized sprayer. It rapidly cuts organic deposits and disinfects the system to circulate fresh & healthy air.

ALSTA SHINE has self foaming characteristics which immediately starts foaming when it comes in contact with dirt, enabling excellent penetration of the cleaning chemical into the coils for complete cleaning that instantly shows increase of CFM/Air Velocity in AHU (Air Handling Units). 

 Why Is Coil Cleaning Important  :   Air passing through the coil contains microscopic and minute dirt particles, as well as other foreign material. After some time, these debris build up on the coil surface, making it more difficult for  the cooling coils to provide cooling. This increases the operational costs. A dirty coil is insulated, & it takes longer time to cool. Unclean coils cause the followings: 1) Equipment are made to run longer giving it more wear and tear, 2) Use up more energy (electricity) than a clean coil, causing the energy costs to rise 3) It circulates un-healthy air & strictly compromises with the IAQ (Indoor Air Quality) Air conditioners are the single most energy consuming appliances in a building or facility. Dirty coils highly increases the operational cost. 

Application  :  AHU, FCU, Air Conditioners, Car Condenser & Radiator external, Air Cooled Chillers, Air Cooled Condenser, Air Cooler Tube Bundle etc.

Chemtex’s Propylene Glycol Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. It treats the surfaces of the metal making them less susceptible to corrosion. It buffers the organic acids formed as a result of glycol oxidation. Inhibited glycol based heat transfer fluids provides corrosion protection without reducing system’s heat transfer efficiency.

It is very important to use inhibitor in glycol system to prevent degradation of glycol. Glycol in presence to heat and air degrades into five organic acids namely :  Glycolic Acid, Glyoxalic Acid, Formic Acid,  Carbonic Acid & Oxalic Acid. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.

Also available Pre Inhibited Propylene Glycol and normal Propylene Glycol.
