Company facts

• Holds UL file XPLH.E342364 for liquid filled pad mounted distribution transformers.
• Its site lists a solar transformer supply to the Stillwater II plant in Nevada as a reference project.
• Builds at two sites near Pereira, an assembly plant on the Pereira to Cartago road and a metalworking plant on the La Virginia to Cerritos road.
• Its site says its manufacturing processes were developed by Colombian engineers drawing on American manufacturing practice.
• US customs records list shipments from Magnetron to an affiliate, Magnetron USA LLC, in Doral, Florida.

How they sell

Builds to order, so a purchase order buys a production slot rather than a unit on a shelf.

In practice that means a purchase order is a place in a queue. Ask for the lead time from purchase order in writing, and ask whether the quoted date is a ship date or a production start. Those are not the same thing and quotes rarely say which.

Where they fit on a job

CO origin makes this a candidate for federal and Buy American work, where TAA eligibility is a hard gate rather than a preference.

If the lead time does not work

These hold stock, so they are where to look when the date will not move.
