Supplier's note

  1. Technical Breakthroughs:

    • Aluminum Alloy 319: 30% lighter than cast iron, reducing engine weight while maintaining heat dissipation.
    • Precision Temperature Control: ±1.5°C accuracy in the Pro Model ensures stable performance in extreme climates.
    • Enhanced Corrosion Resistance: The Pro Model’s 500-hour salt spray rating triples industry standards, ideal for marine or industrial vehicles.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard road vehicles (e.g., Polo sedan) requiring basic thermal regulation.
    • Advanced Model: Recommended for high-performance engines (e.g., Ibiza CUPRA) needing precise temperature control.
    • Pro Model: Best for harsh environments (e.g., off-road Fabia RS) where durability and extreme reliability are critical.

With the Pro Model’s triple-certified corrosion resistance, you can safely handle salt-heavy winter roads or industrial debris. Pair its lightweight aluminum with advanced pressure tolerance to ensure long-term engine protection without compromising performance.
