The electrochemical industry relies on rectifier transformers for processes such as chlor-alkali production, electrolysis, and metal plating. Our high-current rectifier transformers deliver reliable DC power for these critical processes.
Chlor-Alkali Production
Chlor-alkali electrolysis requires large amounts of DC power for the production of chlorine, caustic soda, and hydrogen. Our rectifier transformers are designed to deliver the high currents and stable voltage required for efficient chlor-alkali production, with multi-pulse configurations for improved power quality.
Electrolysis and Metal Plating
For copper electrorefining, zinc electrowinning, chrome plating, and other electrolytic processes, our rectifier transformers provide the precise DC power required. We offer custom voltage and current ratings to match your specific process requirements.
Hydrogen Production
Water electrolysis for hydrogen production is a growing application for rectifier transformers. Our high-efficiency rectifier transformers help minimize energy consumption in hydrogen production facilities, contributing to the economic viability of green hydrogen.
Custom Engineering for Electrochemical Processes
Every electrochemical process has unique electrical requirements. Our engineering team works closely with customers to design rectifier transformers optimized for their specific process, including custom voltage ratios, current ratings, impedance, and cooling methods.

Secondary Current and Duty
Our rectifier transformers for electrochemical duty are designed with secondary currents up to 10,000 A. For context, that sits inside the normal industry band rather than at its edge: a single chlor alkali electrolysis unit typically runs around 40 kA DC, aluminium potline rectifier groups generally fall between 25 kA and 100 kA, and the largest specialist manufacturers publish figures up to 180 kA. 10,000 A therefore suits potline sections, plating lines, water treatment electrolysers and general electrochemical duty without pushing the design into an unusual regime.
What matters more than the headline current is how the unit behaves under it: multi pulse phase shifting to hold grid harmonics down, valve side busbar design that keeps parallel paths balanced, and a cooling arrangement matched to a load that runs continuously at full output. We specify all three against your rectifier topology and duty cycle.
