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.
› 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.
