EERSTA FROST EON FC RM is a coolant specifically designed as a low electrical conductivity coolant for direct cooling of fuel cell stacks. It is a mixture of ultra-pure water and high-purity antifreeze grade glycol. The coolant contains non-ionic additives for corrosion protection and electrical conductivity control. Compatible with stainless steel, aluminum, copper, brass and common elastomers as well as thermoplastics found in cooling systems with the addition of the following benefits:

• low viscosity
• reduced back pressure
• less wear on parts, bipolar plate protection and crack prevention
• organic additive technology
• maintenance-free protection against freezing and boiling
• low and stable electrical conductivity (< 5 μS/cm)
• ready to use, no further manipulation nor dilution needed
• available with bitterant agent for use in aftermarket
• compatible with fuel cell cooling system components including but not limited to the ion exchanger, radiators and hoses
• corrosion protection for fuel cell system components
