REDARTI Thyristor-Controlled Plating Rectifiers are high-strength industrial power systems developed to withstand the heaviest physical operating conditions in heavy-industry surface-treatment plants requiring low or high current (zinc, hard chrome, nickel, copper, anodizing, electropolishing, etc.). In our systems, built with REDARTI's 100% local engineering and manufacturing quality, the electronic boards and sensitive hardware are housed in a specially isolated, protected compartment within the rectifier cabinet to guard against adverse external factors in harsh environments such as corrosive acid fumes, humidity and dust.
Developed for baths operating non-stop under heavy-duty conditions, the SCR-controlled rectifiers are equipped with a high-power transformer architecture offering maximum resistance to overloads, high temperatures and demanding duty cycles, together with top-tier hardware protection units.
Flexible, Customised Cooling Architecture (Air, Water, Oil and Oil+Water)
REDARTI Thyristor Plating Rectifiers can be built with 4 different advanced cooling technologies tailored to your plant's ambient conditions, capacity and project:
- Air-Cooled (A) Systems: A practical and efficient solution for low- and medium-power plating lines with standard ventilation conditions.
- Water-Cooled (W) Systems: Preferred at high power ratings or for special projects, this model uses purpose-made hoses resistant to high temperature, high pressure and chemical corrosion, plus integrated water circulation lines. It prevents heat dissipation into enclosed spaces.
- Oil-Cooled (O) Systems: Designed for special processes with heavily corrosive ambient conditions and continuous long-term operation. Features a specially dimensioned radiator (fin) design with a high heat-transfer surface, matched to the application and plant duty cycle.
- Special-Project Oil+Water-Cooled (OW) Systems: A tailor-made hybrid engineering solution for extremely high current ratings and extreme temperature environments, in which the transformer and power stage are immersed in oil and the oil is cooled through special radiator lines with an external water heat exchanger.
Hardware Isolation, Protection Units and Robust Transformer Design
REDARTI Thyristor Rectifiers are designed to give many years of trouble-free service:
- Electronic Boards Housed in an Isolated Compartment: To prevent acid fumes and corrosive gases from damaging electronic components, the microprocessor control boards and sensitive triggering hardware are protected in a separate sealed compartment inside the cabinet.
- High-Gauss, Powerful Transformer Architecture: A heavy-duty transformer with a silicon-steel core and copper windings of a high insulation class provides maximum resilience to momentary overloads and short circuits.
- Top-Tier Hardware Protection Units: Over-current, short-circuit, high-temperature (thermal), phase-loss and mains-voltage-fluctuation protection, plus water/oil flow-monitoring safety interlocks.
Flexible Control, Display and Automation Options
- Versatile Panel Alternatives: Digital LCD panel, precision analogue meters (voltmeter / ammeter) or Siemens PLC-based colour touchscreen (HMI) configurations, according to customer preference and bath operating habits.
- Remote-Control Box: Optional IP65-protected, wired external control box for convenient operation right at the plating bath.
- Full Automation (100% SCADA / PLC Compatible): In addition to standard RS485 Modbus RTU, integration with automated plants via Profinet, Profibus and 0-10V / 4-20mA analogue interfaces.
