Ultra-EG

Ethylene glycol high‑efficiency heat transfer fluid

Ultra‑EG is a glycol‑based heat transfer fluid designed for industrial cooling systems and HVAC applications where efficient heat transfer and reliable performance are critical. Based on mono ethylene glycol, it is specifically developed for technical systems where there is no risk of contact with food or drinking water. The fluid provides protection against freezing, corrosion and deposit formation, while maintaining low viscosity for improved system efficiency and reduced energy consumption.

Glycol concentration, composition and packaging can be adapted to specific system requirements, and our team is available to advise you on the best options for your application.

Engineered for high‑load industrial systems

Ethylene glycol offers superior heat transfer efficiency compared to many alternative heat transfer media. Ultra‑EG is engineered to utilize these properties in systems that require fast heat exchange, stable performance and dependable operation under demanding conditions.

An advanced corrosion inhibitor package protects system components against oxidation, scaling and metal degradation. This protection helps maintain system efficiency and extends the service life of critical components such as pumps, pipes and heat exchangers.

Stable performance under changing temperatures

Ultra‑EG provides strong freeze protection while maintaining consistent heat transfer efficiency, even during rapid temperature fluctuations. This makes the fluid well suited for installations exposed to varying operating conditions or continuous start‑stop cycles.

Typical applications

Ultra‑EG is commonly used in:

  • Industrial cooling systems
  • Refrigeration installations
  • Large HVAC systems
  • Process temperature control
  • Data center cooling circuits
