HEMP Shielded Generators
Hardened Structures of America offers High-Altitude Electromagnetic Pulse/Geo-magnetic Disturbance (HEMP/GMD) shielded generators as the perfect addition to your hardened or unhardened shelter, home, or commercial/institutional/or government facilities.

Large Power Systems
Did you know that large power systems can be directly affected by Electro-Magnetic storms?

Larger HEMP Protected Electrical Power Systems can be accomplished in several ways.

Multiple generators paralleled together to carry the load

  • Would require multiple shelters and thus be easier to transport to the site

Larger generators, each capable of carrying the load

  • Shelter weight and size may become a limiting factor in certain locations

Pre-engineered construction

  • We design the structure and construct pre-assembled components
  • Size and weight of components would depend on transportation options, rigging equipment on site, and physical restraints on site

Switchgear Retrofit
Our EMP Engineering team can analyze your existing electrical system and design, fabricate and install a switchgear retrofit to mitigate the harmful effects of HEMP.
