GTEMCELL Ltda shielded chambers are built up as modular construction. Due to individual modules, any size of the chamber can be realized. Big chambers may require an outer supporting structure or alternatively, the shielding material can be attached directly to the building. Panels are manufactured of 2,0 mm thickness hot galvanized sheet steel double bordered. 

Gtemcell offers an innovative shielding product made of a highly conductive double layer of aluminum with internal reinforcing mesh in polyester for the coating and creation of shielded environments within pre-existing structures. The application frequencies range from a few Mega Hertz to several GHz with an electric field attenuation of 45-80dB. The great advantage is ease of application even on curved and complex surfaces and lower costs which make this application particularly attractive. GTEMCELL supplies the shielded fabric or performs all the environmental shielding work. The aesthetic finishes are the responsibility of the customer. 

The construction includes a preliminary inspection to evaluate all the "critical" aspects such as the openings present: doors. windows, air conditioning systems, electrical connections and consequently draw up an economic evaluation of the costs. 

Low-profile 12'×10' floor plane with matching vertical wall (up to 12'×10') in galvanized steel. 

Staggered two-layer floor design: wide metal-to-metal overlap, ultra-low impedance, almost zero step height. 

Fast install (1–2 days) with full bonding/continuity verification to the building ground or a shielded room. 

Delivers repeatable EMC/ESD results by minimizing loop impedance and stray coupling paths.

This product is a chamber made of a flexible metal fabric tent assembled as a cavity that provides a periodic electromagnetic environment that is randomly polarized, spatially uniform, and isotropic.

The walls of the chamber are inducted in mechanical vibration between 5 and 20Hz, able to reflect the electromagnetic waves inside the tent with a reverberation effect. VRC finds applications to create an electromagnetic environment for immunity and emission testing. The reverberation tent chamber offers the advantage of higher field-to-input power ratios and faster test throughput times than other test methods.

The IEC 61000-4-21:2003 is a comprehensive standard for performing electromagnetic testing with a reverberation chamber.

The modular construction of the tent fabric allows customized dimensions assembly to meet space limitations e/o including the device under test. The VRC is supplied complete with a technical panel and optional filters.
