Inhibited Mono Ethylene Glycol Brine (Inhibited MEG) is used as an industrial coolant, antifreeze heat transfer  fluid. The inhibitor package is designed to protect brass, copper, solder, steel, cast iron, aluminum and other metals commonly found in the industrial cooling and heating systems.

The effectiveness of Inhibited Mono Ethylene Glycol Brine (Inhibited MEG) in preventing corrosion has been proven in extensive laboratory and in actual service tests. Using Inhibited Mono Ethylene Glycol Brine (Inhibited MEG) for heat transfer applications instead of brine solutions or un-inhibited ethylene glycol reduces maintenance costs and improves heat transfer efficiency.

Chemtex's Inhibited Mono Ethylene Glycol Brine (Inhibited MEG) outperforms Dowtherm, Dowcal and Norkool range of inhibited ethylene glycol based heat transfer fluids.

Applications : Thermal Storage System, Automobile Coolant Manufacturers, Pharmaceutical & Bulk Drugs, Snow-melting & Refrigeration, Cold Storage Systems, Oil Refineries, Ice Skating Rinks, Rubber Industry, Cold Rolling Mills, Milk and Dairy Industry, Meat Processing Industry, Solvent Extraction Units, Vanaspati and Vegetable Oils.

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.

Chemtex’s PG (Propylene Glycol) Brine Corrosion Inhibitor is a special compound designed to prevent corrosion in multi-ways. PG (Propylene Glycol) Brine Corrosion Inhibitor  treats the surfaces of the metal making them less susceptible to corrosion. PG (Propylene Glycol) Brine Corrosion Inhibitor buffers the organic acids formed as a result of glycol oxidation. Inhibited PG or PPG based heat transfer fluids   provides corrosion protection without reducing system’s heat transfer efficiency.

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