We specialize in shielded enclosure manufacturing, modification, 


refurbishment, installation, and RF testing.  CIR manufactures and 


installs steel clad, clamp together, shielded enclosures. We 


recommend the steel clad system because, with its sturdy 


construction, it is more easily modified.

 Our shielded enclosures house magnets manufactured by top names 


like GE Medical Systems, Siemens Medical systems, Philips Medical 


Systems, and Hitachi Medical Systems.
