High Power Transformer Rectifier Systems For Electro Winning and Metal Refining Applications
Added Benefits of Power Electronic Systems Supplied by Neeltran – Robust and Reliable Power to run your 24/7 processes.
At Neeltran, we are uniquely positioned because we are one of the few companies in the world that designs and manufactures its own transformer rectifiers and rectifiers in the same facility under one management team. This unique capability allows for combined Full Current and Full Voltage factory testing of the transformer and rectifier in their actual configuration prior to shipment.
An experienced client requires combined testing to eliminate integration problems at the site and to assure the shortest commissioning time. This results in significant cost savings and produces the highest quality units.
Neeltran possesses multi-industry, engineering, and manufacturing experience that helps us to be flexible and design products that meet your specific technical and safety requirements.
Markets served for electrowinning and metal refining dc power supply: Copper, Nickel, Zinc, Cobalt and other non-ferrous metals that use electrolytic processes.
Product Range: 5 kA to 60 kA per 6 pulse unit, multi-pulse configurations with total process up to 240 kAdc available.
