Due to increased environmental electromagnetic pollution, sensitive and accurate measurements are often affected by RF noise. The application of Comtest RF shielded rooms provides the highest possible shielding attenuation, creating a controlled electromagnetic environment to perform highly sensitive testing without distortion.
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.
Crafted with pure copper panels and copper shield room construction, this RF shield room delivers exceptional EMI protection from 14 kHz to 40 GHz. It maintains over 100 dB attenuation up to 10 GHz, and 80 dB up to 40 GHz. The copper-based construction and RF shielding foil provide unparalleled electromagnetic isolation, making it ideal for EMI-critical installations such as MRI rooms and EMC chambers.
Shielding panels are fabricated from cold-rolled steel with 2-3 mm galvanized sheet, electroplated with copper for seamless shielding. Panels utilize CO2-protected welding and 4.4 cm overlapping seams for mechanical strength and zero EMI leakage. The interior is reinforced with copper finger strips and tape for conductive continuity and assembly integrity.
Incorporates cellular waveguide honeycomb vents (300x300x25mm) for noise-free airflow and EMI suppression. Includes built-in power filtering boxes (16A/25A/30A) for low-leakage AC line entry. Additional copper waveguides, foam absorbers, and beryllium copper fingers ensure thermal management without sacrificing shielding.
Delivered as a turnkey RF shield room solution, it includes copper shielding foil, copper wool rolls, beryllium copper fingers, steel waveguides, anti-static flooring, and compliance-grade EMI filters. Designed specifically for medical and EMC environments, it assures consistent screening for sensitive equipment like MRI scanners.
Tailored to facility size, panel configuration, access door type (manual, electromechanical, or password-activated), power box specs, waveguide-port layout, window options, and optional anti-static flooring. HAOZHUO delivers custom RF shield room solutions scaled for medical, industrial, and defense sectors.
