Organically based coolants for electric vehicles

Renowned makers of electric vehicles rely on factory-side filling with our premium antifreeze concentrate FROSTOX® HT12.

On the premise that electric vehicles are the future standard of CO2-neutral mobility, new requirements will also result in terms of e-engine and battery coolants. Electromobility is thus accelerating the demand for renewable solutions. Organically based products will therefore be playing a decisive role in the use of fossil resources in the automotive industry.

Future driving is electric and organically based.

Passenger cars with combustion engines usually require about 5 liters of coolant; electric vehicles on the other hand up to 18 liters. Monoethylene glycoles (MEGs) comprise 92 – 95 percent of the ingredients. This results in great potential for the environmental balance, in that it is possible to replace them with organically based products made of renewable raw materials.

The renewable monoethylene glycol (bMEG) used by HAERTOL comes from UPM Biochemicals, which is constructing the world’s first wood-based biorefinery for sustainable chemicals made of biomass at the chemicals site of Leuna.

UPM gets its supply of hardwood for production from regional, sustainably cultivated and certified forests. No land is used which competes with agricultural use or the production of food.


Our first sustainable product is FROSTOX® HT12 eco, a premium antifreeze concentrate on the basis of bMEGs which, as a pure drop-in solution, possesses the same chemical composition and functionality as our FROSTOX® HT12.

These bMEGs are made using certified wood sourced regionally in Germany, and are completely recyclable, sustainable and CO2-optimized.
