GTEMCELL Ltda  shielded chambers are built up as a modular construction. Due to individual modules any size of chamber can be realized.  Big chambers may require  an outer supporting structure or alternatively the shielding material can be attached direct to the building.

Panels are manufactured of 2,0 mm thickness hot galvanized sheet steel double bordered. The corners are welded RF-tight. The panels are screwed together all around.  Rf-shielding is guaranteed by a double-row wire mesh gasket.

A standard door 1×2mt clear opening is supplied with 3 rows of contacts. Floor cover can be fitted to individual requirements. Two ventilation honeycomb panels and 2 technical panels supplied. We will can also supply lighting, electrical distribution, interior lining, air conditioning, control and data lines in agreement with the user.

In case of medical use the chambers can be manufactured out of copper or aluminum sheets.
