Solar S1 5 Gallon

Product Code: 155727-0005

An inhibited heat transfer fluid which is designed to protect all solar thermal heating systems at elevated temperatures. This product is effective both in the gaseous and liquid state at temperatures in excess of 356 °F (180 °C).

  • Frost protection to -18.4 °F (-28 °C)
  • Volatile corrosion inhibitor for optimum protection in gas and liquid phases
  • Stable pH across the range of operational temperatures
  • Compatible with all makes and models of solar panels
  • Benchmarked against market leading products
  • Available as 5 Gallon product
Application, Fitting & Dosing

Solar S1 provides corrosion inhibition to all metals commonly found in solar thermal systems. Solar S1 is compatible with all non-metallics commonly found in solar thermal systems. It is ready to use and should not be mixed with other heat transfer fluids or diluted with water or glycol. If other heat transfer fluids have been previously used, drain the system completely and rinse with Solar S1 before filling.

Solar S1 is suitable for use in solar applications with stagnation temperatures in excess of 680°F (360°C) provided that the solar thermal system is correctly installed and dimensioned to allow the Fernox Solar S1 to withdraw completely through vaporization from the collectors when the maximum static temperature is reached. Solar S1 should not be exposed to temperatures of 356°F (180°C) or higher for prolonged periods. Temperatures in excess of 392°F (200°C) causes slow degradation of the fluid which can lead to a reduction in product life.
