Why AURON HT-200?

Developed for high-temperature cooling systems

When standard coolants reach their limits, AURON HT-200 ensures reliable heat dissipation and long-term process stability.

Thanks to its high boiling point and extremely low vapor pressure, fluid consumption remains low even at elevated temperatures. At the same time, its high chemical stability ensures a long service life and reduced maintenance costs.

Outstanding electrical properties

AURON HT-200 combines efficient cooling with high electrical insulation.

Technical specifications:

• Dielectric breakdown strength approx. 30 kV
• Dielectric constant approx. 4.2
• Specific resistance approx. 10¹² Ω·cm

This allows the fluid to safely and directly cool sensitive electronic components.
