GAOHUI Heavy Duty Plating Power Supply (30V/2000A) for Electrocoagulation

This is not another generic cargo-cult rectifier. It is a precision-engineered industrial DC power supply built specifically to solve the brutal operating realities of electrocoagulation wastewater treatment. Where competitor units falter under scale buildup and fluctuating conductivity, the GAOHUI 30V/2000A rectifier delivers unwavering DC current to drive the electrolytic process that precipitates heavy metals and destabilizes emulsified oils. If you are sourcing from a reliable industrial high frequency rectifier factory, you stop over-specifying and start optimizing your CapEx. This unit targets the sweet spot of electro-flocculation: the exact voltage-to-amperage ratio required for high-efficiency contaminant removal.
KEY FEATURES AND ENGINEERING HIGHLIGHTS
Advanced IGBT Inverter Topology: Unlike bulky, inefficient SCR-based units, this rectifier uses isolated-gate bipolar transistor switching to achieve >90% conversion efficiency. This translates directly into lower electricity bills and reduced cooling requirements for your treatment plant. The high-frequency design eliminates copper losses found in traditional low-frequency transformers.
Precision Constant Current/Constant Voltage Control: Electrocoagulation is a current-driven process. As electrode plates foul or water conductivity shifts, this power supply automatically adjusts voltage to maintain your setpoint amperage. This is non-negotiable for achieving consistent floc formation and heavy-duty DC power supply price performance ratio.
Ruggedized Air-Cooled Architecture: For harsh environments where cooling water quality is suspect, this unit uses forced-air cooling. The industrial-rated fans are positioned to keep IGBT modules and capacitors at safe operating temperatures, even at full 2000A output. This air-cooled design eliminates the risk of water leaks destroying your power supply.

PART 2 ADVANCED BUILT-IN PROTECTION SYSTEMS
Your electrodes will short. The water will spike in temperature. A maintenance worker will drop a tool across the DC bus. This unit is engineered to survive those moments with a multi-layer protection stack. It includes: overcurrent (instantaneous foldback), overvoltage crowbar, excessive temperature cutoff (IGBT heatsink), phase-loss detection, and a dedicated arc-fault sensor. The system also monitors load continuity to detect open circuit conditions caused by electrode breakage. This protection philosophy differentiates a proper IGBT rectifier manufacturer from assemblers.
PART 3 TARGET INDUSTRIAL APPLICATIONS
While built for electrocoagulation, this rectifier’s robust DC output makes it suitable for a range of tough electrochemical processes: industrial wastewater flocculation for heavy metal precipitation (removing copper, nickel, zinc, lead), electro-flotation sludge separation, electrolytic descaling of cooling water loops, and electrochemical oxidation of organic pollutants like dyes and phenols. It is also the right choice for bench-scale research moving to pilot-scale validation. The stability of the rectifier is the foundational variable in any reproducible electrochemistry.
PART 4 CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
Your waste stream is unique. Your electrodes are a specific alloy. Your basin geometry is different. We do not believe in forcing your process into a one-size-fits-all box. The GAOHUI engineering team configures each power supply. We can build any custom current voltage rectifier within the range of 1V – 1000V and 1A – 100,000A. Input is AC (single/three phase), output is always pure DC.
Our standard customization modules include: Process Timer for batch dosing cycles, Multi-Stage Profile Control to automatically adjust current/voltage during growth and settlement phases, Ampere-Minute Integrator for dosing based on total charge passed, and Automatic Reverse Polarity to de-passivate electrodes during off-hours. We also integrate Soft-Start to prevent sudden current surges that trip upstream breakers. Control interfaces include RS485 Modbus RTU, Ethernet TCP/IP, and 4-20mA analog. For advanced process control, we offer Pulse Functions (1Hz to 3000Hz adjustable frequency and duty cycle) to modulate electrical double-layer charging and optimize energy usage per gram of contaminant removed. Contact the factory to discuss your specific chemical and physical constraints for a machine that matches your actual process, not a catalogue spec.
