FlexShield designs and delivers passive EMF shielding for Data Centers and high‑sensitivity environments, ensuring compliance, reliability, and long‑term performance.
Low‑frequency electromagnetic fields generated by transformers, high‑voltage lines, busbars, and high‑power cables are a growing technical and regulatory challenge. Increased power density and proximity to sensitive electronics drive failures, performance degradation, and exposure risks. FlexShield ensures reliability, compliance, and safety.
Electromigration, hot‑electron effects, antenna radiation, and long‑term exposure risks impacting people and equipment.
Up to 15% of electronic equipment failures are linked to EMF interference in critical environments.
Long‑term EMF exposure can impact health; compliance limits protect staff and occupants.
EMF interference increases failure rates and degrades sensitive electronics performance.
Shielding safeguards uptime in mission‑critical facilities.
We design solutions for transformer rooms, cable trays, busbars, and sensitive areas such as data halls, labs, and cleanrooms. Each design is tuned to exposure targets and operational constraints.
Validated in laboratory and on‑site conditions with documented results.
High‑permeability and high‑conductivity materials work together to deliver absorption and eddy‑current cancellation at low frequencies.
Shield transformer rooms, cable trays and busbars, or protect sensitive server rooms, labs, and cleanrooms near EMF sources.
Performance‑equivalent shielding with recycled metals to reduce CO2 and water footprint without compromising certification.
Standard, High‑Performance, and Ultra‑High‑Performance trays for power and data runs.
Standard, High‑Performance, and Ultra‑High‑Performance backplanes for sensitive zones.
