Application

RF cages are used to provide electromagnetic shielding for environments where sensitive electronic equipment operates or where electromagnetic emissions must be contained. Commonly installed in facilities such as MRI scanner rooms. The cage prevents external radio-frequency interference from entering the enclosed space and limits the transmission of internally generated electromagnetic signals to the outside environment, ensuring reliable equipment operation and compliance with electromagnetic compatibility requirements.

Description

For an MRI scanner to operate effectively, it must be housed within a fully enclosed RF cage (faraday cage) made up of six sides, consisting of floor, ceiling, walls, control window and entrance door.

RF cages are meticulously constructed using pure electrically deposited copper fixed to a modular timber frame to ensure structural integrity. Each cage is custom designed, manufactured and installed under strict quality control measures.

Features and benefits:

  • Manufactured to suit individual site requirements.
  • Framework made in panels at premises and assembled on-site by trained personnel.
  • Acoustic insulation incorporated within the cavity of the RF copper wall panels and ceiling panels.
  • Constructed using pure electrically deposited copper fixed to a modular timber frame to ensure structural integrity.
  • Custom designed, manufactured and installed under strict quality control measures.
  • All necessary electrical cables, medical gas pipes and other supplies are discreetly routed through the wall cavities of the RF cage.
  • Electrical filters and waveguides are used to protect the RF Cage from any outside interference.
  • Specially designed doors are manufactured to withstand the rigorous demands of MRI facilities while ensuring reliable functionality with minimal maintenance. 
  • Doors meet the required RF attenuation standards and are finished with a high-pressure laminate finish for durability.
  • The control window features an aluminium frame with a layer of blackened copper mesh with a double-layer safety glass, providing clear visibility for operators.
