Supplier's note

1. Key Technical Breakthroughs:

   • Enhanced Chemical Resistance: The Pro Model’s 130-hour resistance triples industry benchmarks, enabling safe use in corrosive environments.
   • Extreme Temperature Tolerance: The Pro’s -40°C to +150°C range outperforms competitors, ideal for Arctic or desert climates.
   • Pressure Handling: The Pro’s 20 MPa rating ensures zero leakage in high-stress industrial compressors.

2. Optimal Version Selection:

   • Base Model: Suitable for standard buses in temperate regions (e.g., urban transit).
   • Advanced Model: Ideal for heavy-duty buses in moderate climates (e.g., long-haul transport).
   • Pro Model: Required for extreme environments (e.g., mining vehicles, Arctic buses) where durability and pressure stability are critical.
     Example: With the Pro’s triple-certified materials, you can safely handle aggressive fluids while maintaining performance in sub-zero temperatures.
