HIGH POWER TRANSFORMER RECTIFIER SYSTEMS FOR ELECTROCHEMICAL APPLICATIONS

Added Benefits of Power Electronic Systems Supplied by Neeltran — Robust and
Reliable Power to run your processes.

Neeltran, is uniquely positioned as one of the few companies in the world that
designs and manufactures its own transformer rectifiers and rectifiers. 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.

This combined testing to eliminate integration problems at the site and to
assure the shortest commissioning time, resulting in significant cost savings
and the highest quality units. Our rectifiers for electrochemical plants will
exceed your needs.

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 for your electrochemical needs. Neeltran
offers oil cooled transformer with water cooled rectifier as well as water
cooled transformer with water cooled rectifier which is the lowest cost solution
(green solution). Whether a traditional Oil Transformer and water cooled
rectifier or an all in one, E House style. Our rectifiers for chemical plants
can servive your needs.

Markets served for electrochemical rectifiers and transformers are: Chlorate,
Chlor alkali, Chlor-alkali, Chlorine, Hydrogen and all other gasses and
chemicals that use electrolytic processes.
