All RF shielded rooms, reverberation and anechoic chambers supplied by Comtest Engineering are built as a modular concept by using the components in our product range as building blocks. This enables us to supply many different and unique solutions in almost every dimension and form. Depending on the application, the flanges of the shielded panels can be installed on the inside. This allows the chamber to be positioned close to the existing walls of the parent building.
This modular frame construction is wrapped with electroplated copper which can conform to any design criteria. The engineered and bolted system enhances RF integrity with wide 4.4 cm (1 3/4") seams that are highly compressed, offering a seamless shield surface. Interior fasteners do not have to penetrate the shield surface by design, which enhances the long-term life of the shield.
The HAOZHUO RF shield room is specifically designed to meet the stringent shielding requirements of MRI systems and EMC environments. With tested shielding effectiveness reaching up to 120dB across frequencies from 14kHz to 40GHz, it effectively isolates sensitive medical equipment from external electromagnetic interference (EMI) and radiofrequency (RF) noise. This ensures uninterrupted diagnostic performance and accurate imaging results. By integrating advanced shielding materials including beryllium copper fingers, brass honeycomb filters, copper panels, and steel waveguides, the system creates a sealed environment ideal for high-precision applications.
Built with modular steel and copper panels, this RF shield box solution allows easy customization based on room size, application, and installation constraints. Every component is engineered for seamless integration, including 2mm/3mm galvanized plates and large-format copper foil (1380mm x 0.105mm). Modular panels enable fast onsite assembly or disassembly, offering minimal downtime during medical room conversions or expansions. Whether for a standalone RF shield room or integration within existing infrastructure, the system guarantees full compatibility without compromising shielding integrity.
The shielding panels are crafted using molded cold-rolled steel plates, jointed and welded with CO2 protection to reduce deformation and enhance mechanical strength. The exterior copper shield (electroplated for consistent conductivity) adheres tightly across seams, while wide 4.4cm overlaps ensure no leakage or weak points in shielding coverage. The durable structure withstands long-term use in high-demand environments like hospitals, research labs, and EMC test centers. The system also includes CO2-protected bolted frames, interior copper tape, and copper wool rolls to enhance surface continuity and longevity.
Each RF shield room comes equipped with precision-designed accessories: MRI doors (standard size 1.2×2.1m), RF shield windows (0.8×1.2m), honeycomb ventilation (300x300mm or 300x600mm), power filters (16A/25A/30A), copper waveguides, and foam absorbers. Optional enhancements like anti-static flooring, steel gasbag doors, and light-activated shielding doors provide complete functional coverage. Every element supports safe, comfortable operation for patients and staff, with rigorous attention to EMI sealing and airflow management.
This system isn’t just a standard RF shielding foil enclosure — it’s engineered for the demands of modern medical imaging facilities. It eliminates electromagnetic distortion in MRI scans, preventing ghosting or artifacts caused by external noise. Simultaneously, its EMI filters and waveguide ventilation system maintain cooling and equipment protection without compromising shielding levels. The result is a medical-grade RF shield room that improves reliability, safety, and diagnostic output.
