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 specially specifies the use of low to very low electric conductive coolants. Please follow the OEM instructions.
Arteco's OAT low conductive coolants are specially designed to use in battery and hybrid vehicles where electrical conductivity is considered as an important parameter.
