Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance Engine Boost: Designed to enhance engine power output in heavy-duty excavators (BL71, BL70, BF4M2012) by compressing intake air, enabling more efficient fuel combustion and increased torque.
  • Durable Metal Construction: Built with robust metal materials (steel/cast iron) to withstand extreme temperatures, pressures, and mechanical stresses in industrial environments.

Key features

  • 1. Corrosion-Resistant Metal Construction

    • With a durable metal body (steel/cast iron), you can ensure long-lasting performance in harsh construction environments. Up to 30% more resistant to wear and heat than standard turbochargers

  • 2. Robust Flange Design for Secure Mounting

    • With a reinforced flange and multi-bolt attachment system, you can achieve stable installation and reliable operation under high-stress conditions. Designed for seamless integration into excavator engines like the EC140/EC210.

  • 3. Enhanced Power Output for Heavy-Duty Use

    • With optimized airflow efficiency, you can boost engine power by up to 25%, enabling faster and more powerful performance in earthmoving and industrial applications. Outperforms standard models in high-demand scenarios.

  • 4. Tailored for Construction Machinery Demands

    • Designed specifically for excavators (BL71/BL70/BF4M2012), you can handle continuous operation in rugged environments. Engineered to adapt to heavy lifting and prolonged use in construction sites.

  • 5. Manufactured to Industrial Quality Standards

    • With Witze’s reputation for precision engineering, you can trust compliance with safety and durability certifications critical for construction machinery. Certifications subject to manufacturer confirmation.

Supplier's note

  1. Three Technical Breakthroughs:

    • Material: Metal construction provides 20% higher durability than plastic alternatives.
    • Heat Resistance: The Pro model’s 800°C tolerance exceeds industry standards by 33%.
    • Customization: Adjustable turbine sizes enable 25% faster airflow optimization than fixed designs.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard excavators (e.g., BL70) requiring reliable, everyday performance.
    • Advanced Model: Ideal for medium-duty operations, offering 15% higher airflow for tasks like earthmoving.
    • Pro Model: Designed for heavy-duty applications (e.g., BF4M2012 engines), with triple the heat resistance of competitors, ensuring safe operation in extreme conditions.

With the Pro model’s 800°C heat resistance, you can safely handle prolonged high-temperature exhausts, paired with its premium rotational speed to maximize power output. The Advanced model’s enhanced airflow makes it 20% faster than traditional models, ideal for balancing cost and performance. Choose based on your engine’s workload and environmental demands.
