High Power Transformer Rectifier Systems For Aluminum Applications
Added Benefits of Power Electronic Systems Supplied by Neeltran – Robust and Reliable Power to run your 24/7 processes.
At Neeltran, we design and manufacture our own rectifier-transformers and rectifiers in the same facility for aluminum duty units. 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 for Booster and Compensation supplies.
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. Please call us for your aluminum smelting power supply needs.
