Radio Frequency Shielded Doors: RF Radio Frequency Barrier & TEMPEST Shielding

KriegerShield

Radio Frequency Shielding

Krieger's radio frequency doors and windows are used in installations where TEMPEST standards are required, or where there exists a need for a radio frequency barrier for high frequency shielding.

RF Shielding Principles (PDF)

Radio Frequency Shield

≥ 60dB of shielding effectiveness in the electric, planewave, and microwave fields in the frequency range of 1 KHz to 18 GHz.

Magnetic field shielding performance meets the attenuation requirements of NSA 73-2A (1 kHz, 10dB; 10 kHz, 20 dB; 100 kHz, 30dB; 1 MHz, 40dB; 10 MHz, 50dB).

Tests and Certifications

Division 8 Standard

NSA 65-6
MIL STD-285

Custom Manufactured to Your Specifications

Door Configuration

Single, or pairs of, hinged doors, in standard and custom sizes, manual or power operated. Assemblies can be tied into any type of shielding construction.

Frame Configuration

Krieger offers standard frame designs and can engineer special frame profiles to complement wall construction and architectural style.

Fire Labels and Positive Pressure

Up to 1½ Hours:

UL 10C, UBC 7-2, UBC 7-4 450° and 650° temperature rise, up to 1½ hours UL 10C

Smoke Labels:

Up to 20 minutes

Robust Seal

Krieger's unique radio frequency seal does not use a knifed edge found in other radio frequency doors, rather it is similar to robust weather stripping, dramatically increasing the door life while reducing maintenance costs.

ADA Compliant

Krieger's radio frequency doors meet the ADA threshold requirements of ½" without portable ramps, allowing them to be used in any location.

Performance Combinations

KriegerShield radio frequency doors can be manufactured for multiple performance requirements including acoustical, bullet resistance, blast resistance or any combination thereof.
