Product Introduction
The HQ-EV0 series motor vehicle antifreeze coolant pioneers the industry as it is crafted from polyester-grade ethylene diol combined with a highly efficient blend of corrosion inhibitors, defoamers, and other superior additives. Its freezing point can be customized to fit specific needs, ranging from an impressive -60ºC to -20ºC. This coolant is engineered for a broad spectrum of temperatures, operating smoothly from a frigid -55ºC up to a scorching 120ºC. It comes pre-diluted, allowing for direct application without the need for additional preparation. Designed for versatility and efficiency, it's ideal for cooling systems in electric vehicle power batteries, motors, electronic controls, and power exchange stations.
With superior thermal conductivity and exceptional metal corrosion protection, it ensures the reliable and safe operation of power batteries and all other electrically charged components.
Championing environmental safety, it is formulated without nitrites, amine salts, phosphates, borates, or silicates, offering a greener, cleaner solution.
The product boasts a replacement cycle of 3 years or 150,000 km, whichever milestone is achieved first, ensuring long-lasting performance.
Compliance with stringent EU RoHS, REACH, and other regulatory standards underscores its commitment to quality and safety.
