Fernox S1 Readymix

Fernox S1 is a clear, orange liquid with a distinct, faint odour. It has been specifically formulated for use as a heat transfer fluid within solar thermal heating systems at elevated temperatures. Fernox Solar S1 employs volatile corrosion inhibitors that will protect the installation when the heat transfer fluid is in either a gaseous or liquid state at temperatures in excess of 180º C.

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.

• An inhibited heat transfer fluid for all solar thermal applications
• Frost protection to -28°C
• Volatile corrosion inhibitor for protection in gas and liquid phases
• Stable pH across the range of operational temperatures
• Compatible with all makes and models of solar panels
