1. Internal Frame
A free-standing, aluminum channeled, post and beam Series 300 frame
supports the weight of port plates, multiple vents for both intake and
exhaust, the modular fabric panels and RF anechoic foam panels. Internal
frame channels are used to create a clamping system with fabric overlaps
to provide an RF tight seal. The patent pending design conductively
connects every horizontal and vertical frame member in the system.
2. Metal Ground Plane Floor
An aluminum sheet ground plane system is conductively connected to the
frame and modular fabric panels allowing heavy units to enter and exit.
The floor plane system uses a rabbet edge design and connected using EMI
shielding gaskets and flush-mount clamping bars. The perimeter floor
plates contain hardware that clamp to the tent’s modular fabric panels
which establishes a RF tight seal.
3. Removable Fabric Panels
The removable panels for the modular tent enclosure are made with
NovaSelect™ conductive silver/copper/nickel fabric, externally coated with
an acrylic that minimizes particle shedding and metal plating breakdown.
The flexible “hardware cloth” is cleanroom ISO Class 7 (Class 10,000 –Fed.
Std. 209) compatible. Every modular panel has stainless steel grommets
installed around the outside perimeter to allow for stud/clamp connection
to frame system and aluminum panel floor system.
The single door / double row flexible magnet seal (US Pat. No.
9,029,714) is a separate detachable panel and uses the aluminum bar
clamping system on larger size enclosures. Because each panel is
conductively connected to each other, the equipment door does not require
a threshold, facilitating access.
4. Modular Anteroom
An external anteroom can be added for access once the main door has
been secured. The anteroom is permanently attached to a modular panel
connecting the unit to the internal frame and aluminum ground plane floor.
The anteroom can optionally accordion fold towards main chamber to help
minimize the footprint.
External anterooms include the standard conductive fabric floor with
heavy duty vinyl protective layering on top and bottom. All four walls and
ceiling inside the anteroom can be covered with optional lightweight fire
barrier or ESD material.
5. Anechoic Foam Panels
Anechoic foam panels are installed on internal frame system as needed.
Encased when specified, to prevent shedding and comply with ISO Class 7
(Class 10,000 –Fed. Std. 209) cleanroom specifications,
