Arteco Expands Low-Conductivity Coolant Options for EV Indirect Cooling Systems

Why It Matters

Low‑conductivity coolants reduce short‑circuit risk and improve thermal management, giving OEMs a safer, more efficient tool for next‑generation EV platforms.

Key Takeaways

• Arteco now offers three low‑conductivity coolants for EV indirect cooling.
• All formulations keep conductivity under 100 µS/cm, meeting GB 29743.2.
• New variants use silicate‑OAT and phosphate‑OAT chemistries for aluminum compatibility.
• Coolants available with bio‑based or recycled base fluids under ECO program.
• Supports battery longevity and faster charging by limiting fault currents.

Pulse Analysis

The rise of indirect cooling architectures in electric vehicles has heightened the need for coolants that do not compromise high‑voltage safety. Traditional antifreeze fluids can conduct electricity at levels that trigger fault currents if a leak reaches battery modules or power electronics. Arteco’s three‑product Freecor EV Milli series, each engineered to stay below 100 µS/cm, directly addresses this vulnerability while meeting stringent Chinese GB 29743.2 and ASTM D8566 specifications, positioning the line as a benchmark for low‑conductivity performance.

Beyond safety, the chemical diversity of the lineup—standard OAT, silicate‑OAT, and phosphate‑OAT—gives vehicle manufacturers the flexibility to align coolant chemistry with specific thermal‑management strategies and aluminum heat‑exchanger designs. The silicate and phosphate variants extend inhibitor life and mitigate residue buildup, a critical factor for long‑range EVs that undergo frequent fast‑charging cycles. Arteco’s ECO program, which offers bio‑based or recycled base fluids, also taps into the automotive industry’s push toward greener supply chains, adding a sustainability narrative to the technical advantages.

For the broader EV ecosystem, Arteco’s expanded portfolio could accelerate adoption of indirect cooling systems, especially as OEMs seek to reduce system weight and improve packaging efficiency. By delivering a solution that blends electrical safety, thermal efficiency, and environmental credentials, Arteco sets a competitive bar that may spur other coolant manufacturers to innovate similarly. The move underscores how ancillary components, once peripheral, are now central to achieving higher energy density, faster charging, and longer vehicle lifespans.
