Arteco coolants not only protect against frost, corrosion or overheating, they also provide a long life fluid, minimising the need for replacement and maintenance! This is Arteco's quadruple protection!
Good news! Arteco coolants are used and already approved for most of today's hybrids!
As a general rule, all current approvals on Arteco products remain valid for the manufacturers' hybrid vehicles. Those are vehicles where the internal combustion engine (‘ICE’) is complemented with some form of electric propulsion. Another version is the extended-range electric vehicle (E-REV), where the e-propulsion system is complemented by an ICE to produce the required electricity.
Where do cooling systems and their coolants differ?
- In today's commercial applications, a liquid coolant is used in so called ‘indirect cooling’ systems. In these applications, the coolant does not come into direct contact with the electric components of the propulsion system, and hence the risks associated with potential short circuits is eliminated. This is why many of the classic coolants may be used.
However, in some cases the manufacturer specifically specifies the use of low to very low conductive coolants. Please read and follow carefully the OEM instructions!
For these coolants, Arteco is your ideal partner for a suitable coolant.
- In ‘direct cooling’ systems, the coolant is in direct contact with the electrical parts of the battery, and needs to be non-conductive. Introducing a regular coolant may damage the battery and/or cooling system permanently, or cause short-circuits. For this purpose, other type of fluids are used.

Frequently asked questions
- What is Electric Conductivity?
Electrical Conductivity (EC) or specific conductance represents the ability of a matter (solid, liquid, gas and plasma) to allow the transport of charged particles. A high EC indicates a material that readily allows electric current.
EC is commonly signified by the Greek letter σ (sigma), but also κ (kappa) and γ (gamma) are sometimes used. The SI unit (International System of Units) of EC is Siemens per meter (S/m), whereas for engine coolants and heat transfer fluids (HTFs) µS/cm is often used.
In electrolytes such as an engine coolant or HTF, electrical conduction happens by ions - which is the collection of anions and cations - traveling, each carrying an electrical charge. The conductivity of ionic solutions/electrolytes varies with concentration of ions and temperature. Think about distilled water as an almost insulator whereas salt water is a reasonable fair conductor.
As can be understood from the above, the quality of the dilution water itself (linked to the total ion content) plays an important role in the EC of the coolant. Secondly, the inhibitor technology is affecting the EC level as well. And in addition, when the coolant or HTF is circulating in the system it might pick up remnants from machining and other contaminants, all having an impact on the overall EC. It is therefore incorrect to deduct from the EC value the dilution ratio of an engine coolant or HTF.
