Why AURON HFE-7100?

Multifunctional fluid for cooling, cleaning, and drying

AURON HFE-7100 was developed for applications that require a combination of electrical insulation, rapid heat dissipation, and gentle cleaning.

The fluid meets these requirements through:

• high flow efficiency
• electrical insulation
• low surface tension
• rapid evaporation
• high chemical and hydrolytic stability
• suitability for single-phase immersion cooling
• versatile use as a coolant, cleaner, and diluent

Outstanding electrical properties

AURON HFE-7100 is suitable for applications where cooling and electrical insulation are required simultaneously.

Technical Specifications:

• Dielectric breakdown voltage: > 25 kV at a distance of 2.54 mm
• Dielectric constant: approx. 7.27
• Specific resistance: > 10⁸ Ω·cm

This makes the fluid suitable for direct component cooling, power electronics, and sensitive electrical assemblies.

Developed for modern cooling systems

AURON HFE-7100 is suitable for, among other things:
