RF/EMI Shielded Rooms

Shielded enclosures can be designed and built from a small desktop mounted unit to Aircraft hangar sized facilities.

Overview

Global EMC’s RF/EMI System 7000 shielded room (Faraday cage) is an electrically conductive volume that can be manufactured and designed in any size or shape. The principle is that radiated electromagnetic waves (magnetic/radio/microwave) hit the exterior of the room and flow around the outside in conducted micro-energies. The typical frequency range of the shield is 10 kHz to 18 GHz but can be extended to 1 kHz to 86 GHz if required. The shielded room can be adapted to Tempest and NEMP requirements upon request. Shielded enclosures can be designed and built from a small desktop mounted unit to Aircraft hangar sized facilities. The shielded enclosure will be made in a bespoke size to fit the host building and maximise the usable space.

The shielding is an enclosure of all walls, ceiling and flooring using 2mm modular pan steel. This shielded enclosure gives superb performance. It is a modular assembly of individual steel fabrications that are produced from 2mm galvanized sheet steel. These are folded at the edges of each panel to form flanges which are bolted together. Double wire mesh gasket is placed between each flange to form a high performance electromagnetic seal.
