Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Rust Prevention: Non-alloy zinc anode designed to sacrificially corrode, protecting marine structures like ballast tanks from rust and corrosion in harsh aquatic environments.
  • Durability: High-purity zinc composition ensures consistent and long-lasting corrosion protection without alloy impurities, maintaining structural integrity over time.

Key features

  • 1. Material Technology

    • With high-purity zinc alloy composition, effectively prevent corrosion in marine ballast tanks, offering 20% higher protection than standard zinc anodes*. The non-alloy designation ensures purity and reliability in harsh saline environments.

  • 2. Performance Parameters

    • With a durable zinc alloy design, provide a 30% longer service life compared to magnesium anodes in saltwater applications*. This extends maintenance intervals and reduces replacement costs for maritime equipment.

  • 3. Scenario Solutions

    • With application-specific design for ballast tanks, ensure optimal corrosion protection in maritime environments where generic anodes may fail*. The anode’s structure is tailored to withstand the dynamic pressure and corrosive conditions of ship ballast systems.

  • 4. Certification Standards

    • With DNV GL certification, meet rigorous marine industry standards for reliability and safety*. This ensures compliance with global shipping regulations and enhances trust for commercial maritime use.

  • 5. Cost Efficiency

    • With cost-effective pricing, reduce maintenance costs by up to 15% compared to aluminum anodes while maintaining performance*. The zinc alloy’s balance of affordability and efficacy makes it ideal for budget-conscious marine operations.

Supplier's note

  1. Technical Breakthroughs:

    • Zinc Alloy Core: Outperforms pure zinc anodes with 15% longer lifespan in chloride-rich waters.
    • Hexagonal Reinforcement: Reduces installation torque by 25% compared to smooth rods, minimizing tool wear.
    • Thread Locking Grooves: Prevents loosening in vibrating environments, a 30% improvement over standard threads.

  2. Version Selection Guide:

    • Base Model: Ideal for small vessels or low-salinity ballast systems (e.g., inland waterways).
    • Advanced Model: Suitable for offshore platforms or ships with frequent saltwater exposure.
    • Pro Model: Best for heavy-duty applications like oil tankers or subsea equipment, where extreme load and corrosion resistance are critical.

With the Pro Model’s 40% higher corrosion resistance than industry standards, you can ensure decades of protection in corrosive marine environments. Pair its nickel-plated threads with reinforced tank fixtures to eliminate maintenance downtime.
