CR-100INNOCHILL

EV & Hybrid Battery Coolant

High-priority low-conductivity coolant for EV and hybrid battery thermal management.

Conductivity
≤ 2 μS/cm
Freeze point
-38°C
Thermal conductivity
0.25 W/m·K
Quick AnswerAn EV coolant has to do more than remove heat. It must protect aluminum and mixed metals, remain compatible with seals and hoses, maintain acceptable viscosity through the operating range and meet the electrical-conductivity requirement defined by the vehicle or subsystem.
