Application Industry: Chlor-Alkali Production, such as membrane/diaphragm cell for Cl₂, H₂, NaOH; Chlorate Manufacturing, such as NaClO₃, sodium chlorite; Water Treatment, such as NaOCl, ClO₂, on-site Cl₂; Precious Metal Refining, such as gold/silver chloride electrolysis.

A Chlor-Alkali Rectifier, unlike standard industrial rectifiers, must keep current rock-solid while blocking reverse events. If the DC wavers — even briefly — side reactions kick in, membranes degrade, product quality drops, or worse, you compromise safety. That’s why it’s the core of any chlor-alkali or chlorination plant.

› Chlor-Alkali Production — That’s Where You Get Caustic Soda and Liquid Chlorine
Take saturated brine. Run electrolysis. Out comes Cl₂, H₂, and NaOH.Membrane cell and diaphragm cell plants use this setup all the time. A Chlor-Alkali Rectifier is the standard choice here.

› Chlorate Manufacturing

Same thing applies. You need continuous DC to make sodium chlorate (NaClO₃), sodium chlorite, and other chlorine derivatives. Both chlor-alkali rectifiers and chlorination rectifiers can handle this.

› Fine Chemical and Water Treatment Industries

These rectifiers power sodium hypochlorite generators, chlorine dioxide systems, and on-site chlorine generation units for industrial water treatment. Chlorination rectifiers are particularly common in water treatment applications.

› Precious Metal Refining

You’ll also find them in electrolytic purification of precious metals. Gold chloride, silver chloride solutions—that sort of thing. Both rectifier types work well here too.

› Exceptional Energy Efficiency and Low Harmonic Performance

36-pulse and 48-pulse configurations as standard. Add APF (active power filter) and THD drops below 3%. Overall efficiency hits 98.5%.

› Advanced Corrosion Protection and Cooling Design

Fully enclosed cabinets, conformal coatings, and optimized cooling. Proprietary designs improve thermal balance and reduce maintenance.

› Modular Hot-Swappable Architecture

Drawer-type modules. Swap a faulty one without stopping production. That’s 24/7 operation.

› Dual-Core Digital Control Platform

DSP + FPGA gives you accurate pulse sync, fast response, soft-start, and automatic current recovery. Minimizes stress on electrolytic cells.

› Grid-Friendly Design

Optimized transformer and rectifier configurations improve electromagnetic compatibility. Less interference with surrounding instruments, better plant power quality.

» Selection Considerations for Chlor-Alkali Rectifiers

› Pulse Number Selection

Match pulse count to local power quality requirements and plant capacity.

6-pulse: Small-capacity applications

12-pulse: Conventional industrial systems

24/36/48-pulse: Large-scale chlor-alkali facilities needing superior harmonic performance

Higher pulse number = lower harmonic distortion.

› Voltage Regulation Range

Cell voltage changes as electrolyzers age. Get enough transformer regulation range to maintain efficient operation over the full service life.

› Cooling Method

Above 15 KA? Use closed-loop pure water cooling. Air-cooled only for lower-capacity installations in clean environments.

› Safety Configuration

High-speed DC breakers and comprehensive protection are essential. No shortcuts.
