GAOHUI 30V 2000A IGBT Electrocoagulation Rectifier for Industrial Wastewater Treatment and Heavy Metal Precipitation

Part 1: Key Features & Engineering Highlights

Heavy-Duty DC Power Supply Engineered for Electrocoagulation: This 30V 2000A industrial high frequency rectifier factory direct unit is specifically designed for demanding wastewater flocculation and electrolysis processes. It delivers stable, ripple-free DC output critical for efficient heavy metal precipitation and electrocoagulation EC water treatment.

Advanced IGBT Switching Technology: Utilizing the latest IGBT modules, this rectifier achieves over 90% efficiency, reducing operational costs compared to traditional SCR units. As a leading IGBT rectifier manufacturer, we ensure minimal heat dissipation and a compact footprint for your plant.

Precision Voltage and Current Regulation: Switch seamlessly between constant voltage (CV) and constant current (CC) modes with a regulation accuracy of +/-0.5%. This is essential for maintaining consistent current density during electrocoagulation, ensuring repeatable treatment results and lower custom current voltage rectifier price per liter treated.

Robust Air-Cooled Design: Built for continuous industrial operation, the forced air cooling system maintains optimal internal temperatures even at full 2000A load. This eliminates the need for complex water cooling loops, simplifying installation and reducing maintenance for your wastewater treatment line.

Part 3: Advanced Built-in Protection Systems

Your investment is safeguarded by a comprehensive suite of real-time protection features. The system includes Over-Voltage Protection (OVP) to prevent damage to downstream electrodes, Over-Current Protection (OCP) to limit surges during flocculation, and Short-Circuit Protection (SCP) for fault tolerance. Additionally, Over-Temperature Protection (OTP) automatically reduces output or shuts down the unit if internal temperatures exceed safe limits, ensuring long-term reliability for your electrocoagulation process.
