Inhibited Propylene Glycol

Chemtex has the full range of Inhibited Glycol either it is Inhibited Ethylene Glycol or Inhibited Propylene Glycol. We are offering both types of Inhibited Glycol. Inhibited Ethylene Glycol is mainly for industrial use except any types of food or beverage or dairy etc. related industries where contaminations of Inhibited Glycol with food or drinks products are possible. In those special cases we have Inhibited Propylene Glycol which especially designed for food grade to use in food products related or manufacturing industries.

Inhibited Propylene Glycol

Bright Green Colored Inhibited Propylene Glycol

The effectiveness of Green Colored Inhibited Propylene Glycol in preventing corrosion has been proven in extensive laboratory and in actual service tests. Using Inhibited Propylene Glycol for heat transfer applications instead of brine solutions or uninhibited propylene glycol reduces maintenance costs and improves heat transfer efficiency.

Boiler Water Alkalinity Builder

Corrosion in general terminology is the destructive attack of metal. Metal loss or damage can occur due to chemical & electrochemical reaction, physical erosion or biological attack. Corrosion is always because of chemical reaction. Water corrosiveness is determined by the impurities present in it. Oxygen, dissolved solids, gases and acids in water attack the common construction material.

Major Problems due to Corrosion:-

  • Metal loss (capital loss)
  • System leakage or burst
  • Water / Fluid contamination
  • Poor heat transfer (power loss)
  • Corrosions are of various types and differ with application to application.

Major Types of Boiler Corrosion:-

  • Uniform/General Corrosion due to high temperature
  • Pitting Corrosion due to high temperature and chloride
  • Galvanic Corrosion due to multi-metals
  • Oxidation Corrosion due to oxygen and carbon dioxide
  • Stress Cracking Corrosion due to high pressure and temp.

Condenser Descalant

Descalants or Descaling Agents are chemical compounds that effectively dissolves, disperse or purge the scales, rust and soil deposits from heat exchangers and pipelines by means of re-circulation method, fill and soak method or immersion method. A descalant is always designed by keeping in mind the type of deposit and metallurgy of the system. Proper Corrosion Inhibitors are added in descalants to avoid damage to system metals.

After acidic descaling of system, it is important to passivate and neutralize the system with proper Passivating Agents for avoiding chances of flash rusting after descaling.

In some cases Scale Softeners and mechanical means like brushing and scrubbing of tubes is also required for heavily fouled systems.

Descaling is a labor oriented job and requires system downtime. Hence, the use of alternatives such as Online Descalants and Antiscalants are getting popular.

Inhibited Ethylene Glycol

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.
