THERMOLIQUID MEG Antifreeze is a heat transfer fluid based on monoethylene glycol. It protects installations against freezing, boiling, corrosion and foam formation. This product is primarily intended for the refrigeration industry. It remains one of the best fluids thanks to its low viscosity at negative temperatures. Consult our guide on glycols to discover all the uses of these products.
If your technical constraints allow it, its harmful nature leads us to recommend replacing it with our THERMOLIQUID MPG.
The advantages of THERMOLIQUID MEG:
- it does not contain nitrite but a 100% organic corrosion inhibitor that provides enhanced protection for radiators, pumps and pipes (note that a dilution greater than 33% of THERMOLIQUID MEG Concentrate would no longer provide sufficient corrosion protection).
- excellent compatibility with elastomers used in seals
- good protection for bus, truck and car engines.
- has a high boiling point that reduces the risk of cooling system overheating
- free of silicates or other mineral salts, it therefore presents no risk of scale deposits.
- can be safely used in cast iron, aluminum or copper alloy cooling systems
- contains a bittering agent (denatonium benzoate) to prevent accidental ingestion.
This product is classified as toxic category 4 by ingestion and toxic to target organs by repeated exposure category 2
THERMOLIQUID MPG avoids the constraints related to this classification.
Dilution table:
| Target freezing point (+/-2°C) | -15 | -20 | -25 | -30 | -35 |
