Magna-Power Electronics is a supplier of power conditioning equipment for DOW Water & Process Solutions EDI Modules and SnowPure EDI Modules. These two companies manufacture and market leading-edge electrodeionization (EDI) modules for the production of ultrapure water. EDI, or electrodeionization, is a continuous process used in industrial and commercial water purification systems, with reverse osmosis, to remove all ions and salts from water. It replaces traditional batch deionization resin bed technology which requires large quantities of chemicals for regeneration.
