GLYCOLS AND BRINES
The application thresholds of water can be expanded to -58 °F up to +338 °F using glycol or brine (pressure compensation is required from approx. 230 °F depending on the water content). The excellent thermal properties of water are only slightly compromised. In addition, a modern additive technology leads to good corrosion protection and improved thermal stability.

Do you have any specific questions about our glycols, brines, services or applications?
Here you will find all the key information you need, clearly and precisely presented, and always available!
What are the advantages of water-glycol based coolant fluids compared to pure water solutions?
What are the advantages of water-glycol based coolant fluids compared to pure water solutions?
Water-glycol mixtures provide reliable freeze protection, prevent corrosion, and improve operational safety in cooling and heating systems. They are ideal for applications where temperatures can drop below 32 °F.
How do I choose the right glycol concentration for my application?
How do I choose the right glycol concentration for my application?
The concentration depends on the required freeze protection: About 25% glycol for -14 °F, and around 45% for -22 °F. Excessive concentration can reduce heat transfer efficiency—always follow manufacturer guidelines.
When is it beneficial to use a brine solution instead of glycol?
When is it beneficial to use a brine solution instead of glycol?
Brines are often used when very high thermal conductivity is needed, such as in industrial processes or geothermal systems. However, they are more corrosive than glycol and therefore require careful material selection and proper inhibitors.
How often should the quality of a water-glycol or brine system be checked?
How often should the quality of a water-glycol or brine system be checked?
An annual analysis is recommended. pH, inhibitor levels, freeze point, and contamination should be monitored to detect corrosion, deposits, and efficiency losses early.
Are water-glycol mixtures and brines compatible with all system materials?
Are water-glycol mixtures and brines compatible with all system materials?
Not all seals, metals, or plastics offer the same level of resistance. Aluminum and galvanized components can be sensitive. Always consult manufacturer approvals and material compatibility charts.
