Engineered for extreme duty cycles, low DC ripple performance, and seamless OEM/ODM integration into electrochlorination skids, hydrogen electrolysers, and heavy chemical process lines.
Electrochlorination—the electrochemical process of passing an electrical current through a brine or seawater solution to produce sodium hypochlorite ($NaOCl$) on-site—serves as a critical foundation for biofouling control, industrial water disinfection, municipal wastewater treatment, and marine ballast water management across Turkey. The core driver of efficiency, longevity, and operational stability in any On-Site Hypochlorite Generation (OSHG) system is its Direct Current (DC) power conversion architecture.
As premier OEM/ODM power supply specialists, Powerstax engineers thyristor-controlled transformer rectifiers and switch-mode DC power supplies tailored specifically to meet the grueling ambient, electrical, and chemical conditions of the Mediterranean, Aegean, and Marmara industrial corridors. In electrochlorination electrolysis, the direct current supply directly dictates cell anode wear rates, energy consumption per kilogram of equivalent chlorine, electrolytic gas venting safety, and overall process uptime.
The electrolytic production of sodium hypochlorite operates according to basic stoichiometry. At the anode, chloride ions undergo oxidation to produce chlorine gas:
To sustain continuous electrolysis without degrading mixed metal oxide (MMO) coated titanium anodes, the electrochlorination power system must deliver precise, tightly regulated current density. Uncontrolled AC harmonics or high DC ripple currents exceeding 5% drastically accelerate anode coating erosion through localized thermal stress and localized micro-pitting. Powerstax rectifiers are designed with sub-2% DC ripple filtering and active constant-current regulation modes, maximizing cell stack lifespans beyond 7 to 10 years even under continuous 24/7 duty cycles.
Industrial buyers in Turkey frequently evaluate two main electrical topologies for OEM/ODM electrochlorination power units: Thyristor (Silicon Controlled Rectifier - SCR) Transformer Rectifiers and High-Frequency Insulated Gate Bipolar Transistor (IGBT) Switch-Mode Power Supplies (SMPS).
| Technical Parameter | Thyristor (SCR) Transformer Rectifiers | High-Frequency IGBT Switch-Mode (SMPS) |
|---|---|---|
| Primary Power Range | High Current / Megawatt Scale (500A to 20,000A+) | Modular Chassis / Scalable Blocks (50A to 3,000A) |
| Electrical Efficiency | 88% – 93% (Load Dependent) | 92% – 96% (High Frequency Switching) |
| DC Ripple Factor | < 5% (Standard 12-Pulse), < 2% with LC Filter | < 1% High Purity DC Output |
| Power Factor (PF) | 0.80 – 0.92 (Requires Compensation at low load) | > 0.95 Active PFC across entire range |
| Thermal & Harsh Enclosure | Oil-Cooled (ONAN/OFAF) or Air-Cooled IP55 Cabinet | Water-Cooled / Air-Cooled Sealed Modules (IP65) |
| Polarity Reversal Speed | Integrated Mechanical or Solid-State Switch (Slow) | Full H-Bridge Electronic Inversion (Fast Reversal) |
For large municipal water treatment facilities in Istanbul (İSKİ) or heavy marine anti-fouling installations in Izmir ports, thyristor rectifiers offer rugged, line-frequency isolation with unmatched tolerance against input grid transients. Conversely, for compact containerized ballast water treatment systems (BWTS) and localized industrial skid systems, modular IGBT power supplies supply spatial compactness and near-unity power factor without heavy external transformers.
A persistent operational challenge in Turkish coastal electrochlorination systems is scaling caused by calcium ($Ca^{2+}$) and magnesium ($Mg^{2+}$) hydroxides depositing onto cathode surfaces during seawater electrolysis. Manual chemical acid washing causes unwanted downtime and chemical handling risks. To eliminate scaling, advanced electrochlorination cells employ periodic Automatic Polarity Reversal (APR).
Powerstax custom OEM rectifiers incorporate programmable polarity reversal logic via high-reliability solid-state switches or motorized reversing contactors. During polarity reversal, the power system smoothly ramps down output current to zero, executes a seamless bridge polarity flip, and ramps back up to setpoint current within milliseconds. This process removes mineral scale automatically without subjecting the electrolytic stack to electrical or mechanical shock.
Customized power supply configurations engineered to meet the geographic, maritime, and municipal standards of key economic hubs in Turkey.
Turkey’s shipbuilding sector in Tuzla and Yalova requires IMO D-2 and USCG compliant electrochlorination rectifiers. Powerstax supplies shock-vibration tested, IP65-sealed DC power units designed for harsh marine engine rooms with ambient temperatures reaching 55°C, ensuring continuous biofouling prevention in sea chests and cooling channels.
Major water authorities across Istanbul, Ankara, and Izmir are actively transitioning from hazardous gaseous chlorine tanks to safer On-Site Hypochlorite Generation (OSHG). Our OEM rectifiers integrate Modbus-RTU and PROFIBUS digital interfaces, allowing municipal SCADA networks to monitor amp-hour production, cell voltage, and power consumption in real time.
Coastal thermal, natural gas combined-cycle, and nuclear power installations (such as Akkuyu NPP and Mediterranean power plants) utilize massive volumes of seawater for condenser cooling. Powerstax custom heavy-duty rectifiers (up to megawatt scale) provide uninterrupted continuous DC power to massive electrochlorination cells, suppressing macro-fouling organisms like mussels and barnacles.
Organized Industrial Zones (OSB) in Bursa, Tekirdağ, and Gaziantep demand electro-oxidation power systems for toxic dye color removal and municipal discharge compliance. Our high-frequency switch-mode power supplies deliver precision current regulation for electrochemical advanced oxidation processes (EAOP).
Desalination projects in drought-sensitive agricultural zones like Izmir, Antalya, and Bodrum rely on electrochlorination for RO membrane biofouling prevention. Powerstax rectifiers deliver precise low-dosage hypochlorite generation, protecting sensitive reverse osmosis membranes from chlorine damage while stopping biological growth.
For Black Sea energy exploration projects (Filyos onshore/offshore processing plants), our rectifiers feature ATEX/IECEx compliant enclosures, structural anti-corrosion coatings, and dual redundant control electronics for non-stop performance in hazardous offshore zones.
The Turkish industrial landscape is undergoing a massive transformation driven by green energy transition goals, international maritime mandates, and strict environmental wastewater discharge codes. As a primary exporter and custom supplier serving Turkish system integrators, Powerstax aligns its power architectures with these emerging trends:
With Turkey's ratification of the Paris Agreement and the implementation of the EU Carbon Border Adjustment Mechanism (CBAM), Turkish industrial exporters—especially in steel, chemicals, and textiles—are under intense pressure to reduce energy consumption. Old transformer rectifiers operating at poor efficiency (<80%) generate massive thermal losses. Powerstax high-efficiency IGBT switch-mode rectifiers (exceeding 94% conversion efficiency) allow Turkish factories to significantly curb kWh energy draw per kilogram of chlorine generated, lowering carbon footprint audits.
Industrial facilities operating inside Turkey’s OSBs often experience grid voltage variations, harmonics disturbance, and transient surges (400V AC nominal grid ±15% fluctuations). Standard commercial power supplies suffer high failure rates under these grid stress points. Powerstax designs custom electrochlorination rectifiers equipped with wide AC input tolerance, integrated transient voltage suppression (TVS), and passive/active power factor correction (PFC) filters to ensure uninterrupted plant operations despite industrial grid fluctuations.
Turkish water engineering skids are increasingly exported throughout Europe, the Middle East, and Central Asia. Turkish Original Equipment Manufacturers (OEMs) demand power systems with international standard certifications (CE, ISO 9001, UL compliance readiness) and universal digital protocol compatibility (CANopen, Modbus TCP, Ethernet/IP). Our customizable footprint designs allow Turkish skid builders to drop complete, pre-tested power modules into their standard skid frames with zero mechanical redesign.
Built on decades of high-reliability power supply engineering, Powerstax combines British design precision with global manufacturing scale to serve Turkey's most demanding applications.
Clean-sheet electrical and thermal engineering. We build power systems customized to your exact physical footprint, cooling type (water/forced air/oil), and enclosure rating (IP20 to IP66).
Every rectifier unit undergoes 100% full-load burn-in testing, high-potential isolation dielectric tests, and documented harmonic analysis prior to shipment to Turkish ports.
Advanced multiphase phase-shifting transformer designs and specialized LC output filtering limit ripple below 2%, dramatically extending expensive titanium anode electrode life.
Comprehensive export documentation including Certificate of Origin (COO), ATR customs forms, CE compliance certificates, and seamless DDP/CIF shipping to Istanbul, Mersin, and Izmir ports.
Clear answers to standard technical, commercial, and import questions encountered during power system sourcing for Turkish projects.
Our electrochlorination power supplies are fully compatible with Turkey's standard 3-phase grid rating of 400V AC at 50Hz. We also design custom multi-tap input transformers supporting 380V, 415V, and 690V AC to accommodate specialized industrial estate (OSB) sub-stations or shipboard auxiliary generators.
For marine and coastal installations in locations like Tuzla, Gemlik, or Iskenderun, we engineer enclosures with heavy-duty IP55 to IP66 powder-coated stainless steel (316L option), conformal-coated internal PCBs, and sealed liquid-to-air or liquid-to-liquid water cooling heat exchangers to prevent salty air ingestion.
Yes. Powerstax rectifiers provide flexible control interfaces including classic isolated 4-20mA / 0-10V analog signals, as well as digital protocols such as Modbus RTU (RS485), Modbus TCP/IP, PROFIBUS, and CANbus. This allows easy plug-and-play communication with Siemens S7, Schneider, or ABB PLCs popular in Turkey.
We provide complete export documentation packages required by Turkish Customs Authorities, including Commercial Invoice, Packing List, Certificate of Origin, ATR Movement Certificate for tariff-free customs entry under EU-Turkey Customs Union agreements, CE Declaration of Conformity, and ISO 9001 factory inspection certificates.
Polarity reversal is managed automatically via integrated digital logic controllers. Users can adjust the reversal frequency (e.g., every 2 to 4 hours) based on raw water hardness levels. The unit safely ramps DC output to zero, toggles solid-state bridge networks or motorized switches, and ramps back to target current with zero voltage spikes.
All standard Powerstax electrochlorination power systems come with a comprehensive 12 to 24 month factory warranty. We offer spare parts kits (including replacement SCR modules, control boards, and fuse blocks) and provide direct remote engineering diagnostics and FAT (Factory Acceptance Testing) video verification prior to dispatch.
