SILENTLITE®
is a unique LED lighting system designed to meet the demands of MRI. It uses non-switch-mode technology to drive the LED lamps and to charge standby batteries (giving seamless uninterruptable illumination in the event of black-outs).

Radio Frequency Shielding
We provide RF shielding - sometimes referred to as a 'Faraday Cage', to cover a wide frequency range from below 1kHz to 40GHz.

EEP installations are used to protect MRI scanners, buildings, rooms, cabins or transportable containers. We build and fit-out to a variety of levels and performance specifications as dictated by the user.

For RF shielding, EEP generally uses aluminium or copper (sheet or foil) and under certain conditions, galvanised steel to form the Faraday cage.

For more information see FAQ ‘Electromagnetic Shielding’

MRI Rooms
To function properly, an MRI scanner needs to sit in a special room or chamber shielded against Radio Frequency (RF) interference. Without such protection the very weak RF signals that emanate from the patient when scanned, would be overwhelmed.

The schematic illustrates the various components that go into making up a typical EEP MRI room.

The critical Faraday cage is constructed using pre-formed aluminium panels, an EEP shielded RF door and generally a laminated mesh window as well. Together these elements go to form a continuous RF shield around, above and below the MRI scanner.

Acoustic and thermal insulation is provided and fitted behind the decorative plasterboard as well as being added to the floor and ceiling. Appropriate physical access points are provided including a ceiling void access hatch and the necessary electrical power and data cabling is installed along with various services; all of which are shielded against RF penetration.

As a pre-cursor to building the room, EEP can also undertake an optional site vibration survey to ensure the ground conditions meet with MRI manufacturers’ specified limits.

EEP also design and install the associated quench system as well as magnetic field shielding to support the MRI installation. For more information on this and our doors, see ‘Shielded Doors’, ‘Helium Quench Pipe Systems’ and ‘Magnetic Field Shielding’.

Modular Rooms (Cabins) and Containers
The EEP portfolio also includes self-contained shielded Modular Rooms (Cabins) and Containers. These are built to various performance specifications and fitted out to a variety of levels as dictated by the user.

Test & Evaluation suites
We provide bespoke solutions to meet the express needs of the client. These solutions vary in physical size, shape and form of construction and include anechoic chambers.

TEMPEST / EMSEC* protected areas
EEP creates an electromagnetic sterile zone in the form of a Faraday cage complete with appropriate electrical filtration supported by EEP shielded equipment enclosures if required. This provides an area protected from electronic eavesdropping; one in which communications – data or voice, can remain secure.

* Electromagnetic emanations / (emissions) security

Electromagnetic Pulse (EMP) Protection
EEP undertakes the hardening of critical facilities against the damaging and disrupting effect an EMP produces. Protection generally comprises a Faraday cage coupled with the necessary surge suppression systems. All cables - power, signal, data and communications (both copper and fibre optic) entering and exiting the protected area, are protected with electrical filters

This work may take the form of a room, a whole building or simply the manufacture and supply of our EMP protected enclosures, cabinets or doors.

To ensure compliance with the high international performance standards needed to protect key infrastructure installations, EEP developed specific test equipment for this critical task.
