Product Introduction
  • NOx Emission Value: ≤30mg/m³, equipped with ultra-low NOx burner.
  • Thermal Efficiency: 96-98%, condensing boiler.

Product Features and Advantages

  • Atmospheric Design, No Monitoring Required:
    Not subject to "Pressure Vessel Safety Law," no inspection needed, saving costs.

  • Three-Pass Structure for More Efficient Heat Exchange:
    The three-pass design ensures that high-temperature flue gases fully circulate inside the furnace, achieving up to 98% thermal efficiency.

  • Efficient Insulation with Minimal Heat Loss:
    Uses new lightweight insulation materials, resulting in minimal heat loss and excellent insulation performance.

  • Comprehensive Protection for Peace of Mind:
    Equipped with over-temperature, overpressure, and gas protection systems, ensuring stable operation and safety at all times.

  • Fully Assembled for Quick Installation:
    Integrated design, compact and elegant structure, fully assembled for quick installation, shortening the construction period.

  • High-Efficiency Combustion with Low NOx Emissions:
    Equipped with a well-known brand burner for complete combustion, high thermal efficiency, and low fuel consumption, achieving low NOx emissions.

  • Flue Gas Turbulence Technology for Improved Heat Exchange Efficiency:
    The convection section uses flue gas turbulence technology to increase the heat exchange surface area, significantly improving efficiency.

  • Condensing Heat Exchange for Fuel Savings:
    A condenser can be installed at the flue outlet to fully absorb the latent heat of the flue gas, significantly improving fuel savings, with thermal efficiency exceeding 100%.

  • Corrosion-Resistant Special Steel Condenser:
    To prevent acid corrosion from flue gas condensation, ND steel and other special materials are used for the finned tubes, improving heat transfer efficiency.

  • Intelligent Control with Multi-Unit Group Control:
    Features a colorful touchscreen PLC control system for easy operation, automatic fault diagnosis, and fully automatic operation.
