What We Protect

HEMP Shielding for Critical Equipment & Operations

Our shielded structures and enclosures reduce site vulnerability and protect critical infrastructure operations, military, government agencies, business data sites, hospitals, and more.

In the digital era, data centers are the heart of enterprise operations. Gaven Industries' HEMP-shielded enclosures are engineered to protect these nerve centers from EMP disruptions, ensuring the integrity and security of data. Our robust shielding technology defends against data loss and downtime, preserving mission-critical online services and digital commerce activities.

Modern buildings rely on complex environmental systems for functionality. Our enclosures provide a fortified barrier for generators, HVAC, and other operational technologies, safeguarding against electromagnetic incidents that could otherwise cause failures, ensuring continuous operation and occupant safety in commercial and residential buildings.

Integral to industrial control systems, SCADA systems monitor and control infrastructure, industrial, and facility-based processes. Gaven Industries designs HEMP-shielded enclosures specifically for these systems, providing a secure environment that prevents electromagnetic interference, thus ensuring uninterrupted industrial automation and critical public utility services.

We prioritize quality control at every stage, guaranteeing that all components meet rigorous standards. Gaven's kits undergo quality checks, both at the factory and at the job site, minimizing the risk of installation or operational issues.

Operations centers are critical for situational awareness and decisive action in both crisis and routine scenarios. Gaven Industries' enclosures are tailored to preserve the functionality of these centers under EMP threats, enabling seamless coordination and management of resources, personnel, and information across various sectors.

Military and defense readiness depends on the resilience of command centers. Our HEMP-shielded solutions are crucial in maintaining operational command and control (C2), as well as advanced communication, computer, intelligence, surveillance, and reconnaissance capabilities (C4ISR, C5ISR). These secure enclosures ensure that strategic and tactical operations can be conducted without the risk of disruption from electromagnetic events.

Gaven Industries' shielded enclosures are vital for medical operations and research laboratories, where precision and reliability are paramount. They protect sensitive medical devices and research instruments from electromagnetic interference, ensuring that medical procedures and scientific experiments can proceed with accuracy and without data compromise, contributing to patient safety and scientific advancement.

Refer to the attenuation characteristics charts to determine what material and cell size are right for your application.

Angle Frame:

  • This construction method typically involves a frame made of angled metal sections.
  • The frame is attached to the structure of the shielded enclosure, providing support for the waveguide material.
  • Angle frame construction is often used for installations where a rigid frame is required to maintain the shape and integrity of the waveguide panels.

Ducted:

  • Ducted waveguides are designed with a duct-like structure, allowing airflow to pass through the interior of the waveguide.
  • This construction method provides a pathway for air to flow while maintaining EMI/RFI shielding integrity.
  • Ducted waveguides are commonly used in HVAC systems where maintaining airflow is crucial, such as in data centers or industrial settings.

Ducted w/ Man Bars (Secure):

  • Ducted waveguides with man bars incorporate additional metal bars or grilles within the duct structure.
  • These man bars help to reinforce the waveguide and provide additional support for the ducted airflow.
  • This construction method is suitable for applications where increased structural integrity and security are required, such as in high-security environments or specialized industrial applications.
