Data Centers
Modern data centers operate in one of the most demanding electromagnetic environments today. High-density server racks, power distribution systems, and cooling infrastructure create multiple pathways for EMI and RFI to enter or escape the system.
At MAJR Products, we design EMI and EMP shielding solutions that support the full data center environment—from enclosure integrity to airflow systems—helping ensure performance, security, and compliance in mission-critical facilities.
The EMI Challenge in Data Center Environments
Government and commercial data centers are densely packed with servers, routers, and power systems, all operating simultaneously. These systems generate and are exposed to electromagnetic interference from both internal and external sources.
Without proper shielding, these environments can experience signal degradation, system instability, or data integrity risks.
But shielding in data centers is not just about blocking signals. It must coexist with airflow, cooling, and accessibility—making design significantly more complex than traditional enclosures.
Integrated Shielding Across Data Center Systems
Effective EMI shielding in data centers requires a system-level approach.
Shielding must be applied across:
- Enclosures and cabinets
- Doors, panels, and access points
- HVAC systems and ventilation paths
- Cable and power ingress points
Each of these areas represents a potential vulnerability if not properly addressed. MAJR’s solutions are designed to create a continuous electromagnetic barrier across all system interfaces.
Shielded Ventilation and Airflow Control
Data centers rely heavily on airflow to manage heat, especially when using high-efficiency or evaporative cooling systems.
However, every airflow opening introduces a potential EMI leakage path.
MAJR’s honeycomb ventilation panels and shielded airflow solutions allow facilities to maintain cooling performance while preserving shielding integrity. These systems are engineered to support high-volume airflow without compromising electromagnetic attenuation.
Applications in Data Center Design and Retrofit
MAJR supports data center projects across multiple phases, including:
New construction, where shielding is integrated into the facility design from the beginning.
Retrofits and upgrades, where existing environments must be brought up to modern EMI and EMP standards.
Secure and government facilities, where shielding must meet strict compliance requirements.
We also support reverse engineering and replacement of legacy shielding systems, ensuring continuity without requiring full redesign.
Meeting Data Center Shielding Requirements
Data center environments often require compliance with stringent shielding and EMC standards, depending on application. These may include:
- TEMPEST / secure facility requirements
- EMC compliance for commercial infrastructure
- EMP protection for critical systems
- ICD/ICS 705 compliance for secure data
MAJR products are designed and tested to support these requirements across both commercial and government environments.

White Paper – How Military-Grade Shielding Strategies Protect Government and Commercial Data Centers From EMI & RFI
Government and commercial data centers are densely packed with servers, routers, power supplies, and network switches, making them susceptible to both electromagnetic interference (EMI) and radio frequency interference (RFI). Such interferences tend to come from both internal and external sources, including improperly shielded equipment, nearby broadcast towers, industrial machinery and purposeful criminal activity. Left unaddressed,…
