Product Information

Evans Extreme Duty remains liquid to -67ºF, and its atmospheric boiling point is 298ºF, making it an appropriate coolant for all regions, including arctic and equatorial. Evans Extreme Duty is formulated with a blend of glycols and anti-corrosion additives that do not require water to dissolve. Its high boiling point and the absence of water vapor, acts to fight cavitation and the low electrical conductivity of Evans Extreme Duty, sharply reduce incidents of electrolysis.

  • Boiling Point: Above 298°
  • Antifreeze Properties: Protects below -67°F
  • Benefits: Reduces maintenance, Improved viscosity, prevents boil-over, lower system-pressure, provides unbeatable protection against corrosion and electrolysis.
