Ethyleneglycol

What is ethylene glycol used for?

Ethylene glycol is used as a coolant in cooling systems, for example a chiller or freezer. A common problem in cooling systems is wear caused by limescale and rust. Using ethylene glycol prevents this and considerably extends the service life of cooling systems. These glycols are used in the refrigeration and HVAC industries.

Applications of ethylene glycol

Huchem supplies special ethylene glycol for refrigeration and HVAC installations. It contains inhibitors and additives against rust and limescale and is non-corrosive. The product is virtually odourless and slightly viscous, mixes well with water and is not volatile. Axti Temp E is colourless and transparent as standard, but can also be supplied in blue and red (on request).

Advantages of this product

• Non-corrosive
• Inhibited against corrosion

Instructions for use

At a new start-up, drain the entire system and clean and flush it thoroughly. Then add the required amount of glycol. Let the system come up to operating temperature slowly and allow the air bubbles to escape. Top up the system to the required level if necessary.

Mixing ratio

• 20% product, 80% demineralised water = protection to -6°C
• 30% product, 70% demineralised water = protection to -13°C
• 40% product, 60% demineralised water = protection to -21°C
• 50% product, 50% demineralised water = protection to -33°C
• 60% product, 40% demineralised water = protection to -57°C

As mentioned above, Huchem also supplies ethylene glycol undiluted, see Ethylene Glycol 100%. Ethylene glycol is available in various pack sizes; for smaller users a 20 litre can is available from our webshop. Would you like a specific mixing ratio or quantity? Please contact us.
