Mixture Mono Ethylene Glycol with Demi-Water (Customized)
Buy MEG with Demi-Water Mixtures in Bulk, Drums and IBCs – Custom Blend Ratios Available
Rotterdam Chemicals Group supplies customized mixtures of Mono Ethylene Glycol (MEG) and Demineralized Water (Demi-Water) for industrial and technical applications where high thermal efficiency, reliable freeze protection, and consistent system performance are required.
These MEG-based mixtures are supplied as ready-to-use fluids to eliminate on-site blending and ensure accurate concentration control. By combining MEG with mineral-free Demi-Water, the mixture delivers excellent heat transfer performance, controlled viscosity, and predictable freezing point behaviour, while reducing the risk of scaling and fouling in closed-loop systems.
Rotterdam Chemicals Group supplies MEG and Demi-Water mixtures in multiple ratios to match your operating conditions. Typical ratios include MEG/Demi-Water 20/80, 30/70, 40/60, and 50/50. Other ratios are available upon request to support specific freezing point, viscosity, and thermal performance targets.
What is the MEG and Demi-Water Mixture?
A mixture of Mono Ethylene Glycol (CAS 107-21-1) and Demineralized Water (CAS 7732-18-5) is a clear, colourless liquid formulated to deliver efficient heat transfer, freeze point depression, and corrosion protection in industrial systems.
Mono Ethylene Glycol is characterised by its high thermal conductivity and low freezing point, making it a preferred glycol for applications requiring maximum heat transfer efficiency. Demineralized Water provides a low-mineral, low-conductivity base that supports stable system operation and reduces the risk of mineral deposits and heat exchanger inefficiencies.

Frequently Asked Questions (FAQ)
Why choose a pre-mixed MEG and Demi-Water blend?
Pre-mixed blends ensure accurate concentration control, reduce handling on-site, and deliver predictable system performance.
Can you supply a specific MEG concentration?
Yes. Standard ratios include 20/80, 30/70, 40/60, and 50/50, with custom ratios available on request.
What packaging formats are available?
The mixture is supplied in bulk, drums, and IBCs. ISO tank supply can be arranged on request.
Is a high-purity blend available?
Yes. High-purity blends are available for applications requiring tighter control of impurities and conductivity.
