Resense Transformation of High-Capacity Circular Batch Galvanizing Line for JODEAR Group

Project Overview

• Client Name: Chongqing Jiangdian Power Equipment Co., Ltd. (Jodear Group)

• Industry: Power Transmission & Steel Structures

• Project Type: Brownfield Upgrade (Old Line to Circular Layout)

• Key Challenge: Maximizing throughput within existing space while meeting strict environmental NH3 emission standards.

Client Background

Jiangdian Group (Est. 1996) is a leading modern enterprise in China’s power infrastructure sector, boasting an annual output of RMB 2 billion. With three major production bases covering 800+ acres, they are a core supplier for State Grid and China Southern Power Grid. Their products are exported to 40+ countries across Asia, Africa, and Latin America.

Technical Specifications

This project involved upgrading a traditional line into a high-efficiency Vertical Circular Galvanizing System.

Key Technical Highlights & Innovations

1. Circular Layout Transformation

We converted the client’s aging linear facility into a Vertical Circular Galvanizing Line. This significantly optimized the material flow, reduced crane idle time, and increased the "Dips per Hour" to 8, maximizing ROI for the existing factory footprint.

2. Advanced Emission Control (NH3 Removal)

To meet modern environmental ESG standards, the line features a sophisticated dual-stage filtration system:

• Side + Top Suction: Captures 98%+ of fumes at the source.

• Spray Tower Post-Dust Collector: Specifically designed to neutralize and eliminate Ammonia (NH3) from zinc smoke, ensuring clean emissions.

3. Energy Efficient Flux Heating

We implemented a Graphite Heat Exchanger for the flux heating system. Compared to traditional methods, this provides superior corrosion resistance and thermal conductivity, drastically reducing energy consumption.

4. Integrated Smart Control Center

The line is managed by a Centralized Monitoring System (CMS).

• Real-time Analytics: Displays and adjusts all operational parameters.

• Live Surveillance: Integrated video feeds for total shop-floor visibility and safety management.

  
  

The Result

The upgraded line has empowered Jiangdian Group to produce ultra-high voltage (1100KV) power tower components with higher consistency and lower environmental impact, cementing their position as a top-tier global supplier.

"This transformation didn't just boost our capacity; it modernized our entire environmental and management workflow."
