Glycol or Inhibited 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. Chiller Circuit Glycol Brine is used for lowering the freezing point and enhancing the heat transfer efficiency.

Glycol Brine Solutions are of majorly 3 types used in today's world for heat transfer & thermal storage, such as Mono Ethylene Glycol (MEG), Propylene Glycol (PG) and Diethylene Glycol (DEG). Inhibited Mono Ethylene Glycol(Inhibited MEG), Inhibited Propylene Glycol (Inhibited PG) and Inhibited Diethylene Glycol (Inhibited DEG) Brine solutions are also available that provides protection of metal against crevice and cavitation corrosion.

General Name: Ethylene Glycol based Heat Transfer Fluid


Synonyms: 1,2-Ethane-di-ol, Ethylene di-hydrate, 1-Ethylene Glycol etc.


Product Description:


 Mono Ethylene Glycol (also referred as Ethylene Glycol) is an organic compound having molecular formula as HO-CH2-CH2-OH. Ethylene Glycol is widely used as an antifreeze and automotive heat transfer fluid. It is clear, colorless and practically odorless liquid completely soluble in water.

Handling Measures, Precaution & Storage:


 Mono Ethylene Glycol is toxic and must be handled with all necessary precautions. Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals.


 Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. It should not be injected.


 Ethylene Glycol is slightly hygroscopic & must be stored under conditions so that contamination with water and adsorption of moisture are prevented.


 The storage temperature of MEG is not critical, in that there will be no hazardous condtions created by storage of this product at any ambiance temperature likely to be encountered. 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.


 MEG is a stable chemical and is not expected to deteriorate significantly with time provided if it is stored as indicated. As a good industrial practice, it is however recommended that it should not be stored for periods longer than 6 months.


 Bulk tanks should be of HDPE, non-rusted stainless steel or mild steel. Hoses should be of polypropylene or SS.


 Drums should be stored in dry conditions away from sources of direct heat, preferable in the unopened original containers. Opened drums must be re-closed tightly immediately after drawing out material.
