    Description

    Structure & Working Principle​

    1. ​Tank System​

      • ​Double-layer insulation: 6mm carbon steel inner tank with epoxy anti-corrosion coating + 50mm rock wool insulation (static heat loss ≤12°C/8h).
      • ​Rapid heating: Achieves 10–15°C/h heating via Riello burner and thermal oil coils, maintaining asphalt viscosity at 160–200°C.

    2. ​Smart Spray Control​

      • ​Dynamic calibration: Automatically adjusts pump speed (0–1450 rpm) based on input parameters (spray volume: 0.3–3L/m², width: ≤4m) and real-time vehicle speed (0–15 km/h).
      • ​Dual operation: Preset recipes via cab touchscreen or manually override settings for complex areas (e.g., corners, manholes).

    3. ​Hydraulic Folding Spray Bar​

      • ​3-section design: Horizontally extends to 4m, vertically adjusts height, and pivots 30° for obstacle avoidance.
      • ​Redundant pipeline: Built-in backup channels ensure uninterrupted operation during nozzle maintenance.

    4. ​Self-Maintenance System​

      • ​Nozzle cleaning: Post-operation auto-flushing with diesel and compressed air reduces clogging risk, extending nozzle lifespan by 40%.
      • ​Fault diagnostics: Siemens PLC monitors temperature, pressure, and flow, triggering alarms and logging error codes for quick troubleshooting.

    ​Applications​

    • ​New road construction: Base layer priming (0.3–0.5L/m²), waterproofing (1.2–1.5L/m²), and bonding layer (0.8–1.2L/m²).
    • ​Road maintenance: Crack sealing with modified emulsified asphalt, bridge deck repairs.
    • ​Extreme conditions: Operates at -15°C with preheated thermal oil circulation.

    ​Technical Advantages​

    • ​Energy efficiency: 20% lower fuel consumption vs. competitors due to optimized burner frequency control.
    • ​Multi-media compatibility: Easily switches between hot asphalt, emulsified asphalt, and rubberized bitumen with modular pump/valve components.
    • ​Global compliance: Supports 380V/220V power and diesel generators, meeting EU, Asia, and Middle East standards.
