Hydrogen DC Power Supply for Green Energy Projects

DC Power Supply for Hydrogen Production

Neeltran Industrial DC rectifiers are custom designed to meet your hydrogen needs. Whether an indoor or outdoor solution, an oil or water cooled transformer, a compact or walk in rectifier (E-House) we have the ability to meet all of your specifications. Our team builds / designs transformers and rectifiers in its Connecticut facility to provide you a dc power system solution that exceeds your requirements.

Our rectifiers can power Green Hydrogen electrolyser production that uses Alkaline, PEM, and Solid oxide electrolyzers in hydrogen production.  Typical hydrogen applications are Fuel, Energy Storage, Energy Generation, and Industrial hydrogen.

Global Service

Neeltran services DC rectifiers in USA, North America, Central and South America, EU and in all other countries in which we sell.

Value to the Customer -

Reduced land footprint, ease of installation and lower install cost, no potential for environmental issues in many cases.

Range size from 1MW to 100 MW for electrochemical rectifiers.

Combined Full Current and Full Voltage factory testing of the transformer and rectifier in their actual configuration prior to shipment means quick start ups and improved quality.
