TotalEnergies Coolelf EV Micro – Premium Coolant for Fuel Cell and Electric Vehicles
TotalEnergies Coolelf EV Micro is a ready-to-use premium coolant for fuel cell electric vehicles (FCEV) and battery electric vehicles (BEV). It is based on ultra-pure water and high-purity ethylene glycol with low electrical conductivity. The non-ionic additive technology is free from 2-EHA, nitrites, borates, and amines, ensuring environmental compatibility and excellent material protection. Boiling point: 108 °C (ASTM D1120).
Product Advantages
• Ready-to-use mixture with ultra-pure water – no mixing required
• Designed for fuel cell and battery electric vehicles
• Excellent corrosion protection for aluminum, copper, brass, stainless steel, and other FCEV/BEV components
• Compatible with ion exchangers, radiators, hoses, and common elastomers and thermoplastics
• Very low and stable electrical conductivity (<3 μS/cm at 25°C; <5 μS/cm at 60°C, ASTM D1125)
• Low viscosity, reduced pressure, and lower wear thanks to non-ionic additives
• Prevents cracking and corrosion on bipolar plates
• Maintenance-free due to stable inhibitors
• Environmentally friendly through carefully selected additives
Typical Applications
• Fuel cell electric vehicles (FCEV)
• Battery electric vehicles (BEV)
