Full Turnkey Solutions

We offer the Raymond EMC Modular R.F. Shielded Enclosure System as a full turnkey solution starting from the design phase through to the on-site installation and R.F. Shielding Effectiveness certification complete with any electrical, HVAC, life-saving system or seismic requirements. 

Our basic Modular System consist of solid core panels, made from two 28 gauge galvanized steel panels laminated to a high density wood core, clamped together using a 1/8” galvanized roll-formed framing system.  Special tri-lobular rolling/thread-forming TORX fasteners set on four inch centres of the framing system ensure an RF-tight seal while providing even compression down the entire length of each piece of framing.  Corners are sealed using bronze cast tetrahedral corner caps.

The standard R.F. Shielded Door for our Modular System is our manually-operated  single knife-edge QuietDoor however any of our R.F. Shielded Doors can be easily integrated into our System.

We offer a complete list of options to satisfy virtually any client requirements.

  • R.F. Vestibules for maintaining enclosure integrity during personnel entry and exit
  • R.F. Power Line Filters for bringing AC or DC power into the enclosure
  • Full internal electrical distribution including load centre, power outlets and light fixtures
  • R.F. Signal Line Filters for bringing control voltage in and out of the enclosure
  • Honeycomb Waveguide Air Vents for heating, ventilation and air conditioning including dielectric ductwork canvas collars for properly connecting incoming parent building ductwork to the air vents
  • 12” x 12” Brass Bulkhead Connector Panel
  • R.F. connectors and filtered feedthroughs
  • Copper Screen Panels for viewing windows (Reduces overall R.F. Shielding Effectiveness)
  • Waveguide pipe penetrations for water- or gas-based fire suppression systems
  • Waveguide pipe penetrations for bringing fibre optic cables into and out of the Enclosure
  • Absorber and ferrite tile lining
  • Cosmetic finishes including drop ceiling, commercial-grade vinyl floor tile, raised computer floors and cosmetic wall finishes
  • Functional finishes including ESD floor tile, acoustic wall finishes and sound-proofing panels
  • Shielded column wraps for Enclosures built around parent building support columns
  • Seismic Engineer-approved structure support systems

Versatile Design Capabilities

Our Modular System can be expanded or reduced to meet virtually any size requirement while maintaining its R.F. Shielding Effectiveness performance characteristics. Smaller modular enclosures are designed to be free standing structures whereas larger enclosures can be easily tied into parent room walls and ceilings where support is required. For seismic locations or locations where support from the parent building is not possible, enclosures are supported with specially designed and engineer-approved support structures that meet local zone ratings.

Our highly experienced team of engineers and draughtsmen works directly with the client to ensure optimum room layout and conformity to both client and industry specifications. The proposed layout is then modeled using the latest SolidWorks 3D CAD software package allowing us to provide highly accurate and realistic drawing packages to our clients for their approval prior to manufacturing.

Wide Range of Applications

Our System is suitable for practically any size enclosure, ranging from our 4’ x 6’ x 7’ QuietStation R.F. shielded workstation to 3000 sq. ft. IT departments and aircraft hangars.

Typical applications include

  • Security Areas
  • EMC Product Compliance Testing
  • Instrumentation Repair and Calibration
  • Production and Quality Product Line Testing
  • Cellular and Paging Service Centers
  • High Voltage Test Labs
  • Secure Computer Rooms
  • Wireless Product Testing
  • Metrology Labs
  • Magnetic Resonance Imaging (MRI)
  • Medical Equipment and Instrumentation
  • Biomedical Engineering Labs
  • Embassies and Consulates

Easy Installation

Raymond EMC employs some of the most experienced Installation Specialists in the industry with extensive experience installing our full turnkey Systems including complex electrical, mechanical and architectural components.

The materials for our Modular System are pre-cut in our factory as per client-approved assembly drawings prior to delivery to the client site. This ensures a quick installation process with minimal interruption at the client site. 

Standard R.F. Shielding Effectiveness

Our standard Modular System meets or exceeds the R.F. Shielding Effectiveness requirements as outlined in the military, scientific and medical specifications that govern the R.F. Shielding industry.

Magnetic Fields: 20dB at 1kHz rising to 55dB at 10kHz and 95dB at 200kHz
Electric Fields: 100dB from 200kHz to 50MHz
Plane Waves: 110dB from 50MHz to 1GHz
Microwaves: 100dB at 10GHz
(Shielding Effectiveness Testing Standard: ITSG-02, IEEE Std 299-1997, NSA-65-6)

Raymond EMC offers on-site R.F. Shielding Effectiveness Certification, as per ITSG-02 or IEEE-299, on all installations to certify our product.

Complies with Industry Standards
Our Modular R.F. Shielded Enclosure System conforms to the following industry standards: 

Method of Attenuation Measurements for Enclosures, Electromagnetic Shielding, For Electronic Test Purposes. 1956
