Letter Re: A Closer Look at TruProtect EMI/EMP-Shelter Bunkers
Jim,
I’m the CEO of TruProtect. I have noticed that every time you mention our Faraday cage shelters that our web site visit statistics go off the charts. The only problem is that [few of the visitors] stay and look at the bunkers in detail. People just assume that they are little bitty things. But you can live in these, and live pretty nicely.
Here is the key information about our [RF/EMI/EMP-]shielded bunkers: The regular storm shelter bunker variants are just alike except we omit the RF/EMI door and replace it with a storm steel door. We also omit the RF/EMI filtering on the electrical, data and the filtering on the HVAC. We cover the floor with either indoor outdoor carpeting or a high grade astroturf. Your choice. We can also put a final coat of paint on the walls and ceiling, your choice of colors.
We were asked to design and build the original bunkers for a banking concern in Brazil so they could shield their computer data [emanations from TEMPEST-type hacker interception]. We started with a new 40′ shipping container and built 3 that were shipped down there. There are plenty of the used ones but we decided to use the new ones because they have no dings or splits in them. Besides you never know what they were used for or what was shipped in them. Once the customer got them and put them to use they were ecstatic. In effect you have a double faraday cage once we are through modifying them. You can see everything TruProtect has to offer at our web site. We can taylor TruProtect for about any need or situation.
In building the bunkers we first lined the floor with 1/4″ steel overlaying the usual wood flooring. Then we took the TruProtect RF shielding modules and applied them to the ceiling. We chose the modules(pictured on our web site) because they offer the shielding and the added bonus of the 18 gauge (g) metal. We filled the 3″ void with fiberglass and this added comfort and more sound proofing. Then we added the TruProtect RF modules to the walls. All this shielding is started at the front and brought to the 4′ mark from the rear 2 doors. At this 4′ mark we added a 3/8″ steel wall across the opening. This wall is then covered with the TruProtect RF modules as well. It is in this wall we weld in a RF door. These doors are custom made and our cost is $7,500, alone. These doors are used in all Army, Air Force and many other government installations because of the way they work and they are care free for years. It is rated at 60-70db so it is a very [RF emanations] secure door. Once we get the door installed we add shielded electrical and data ports to this wall on the left side. On the right side we place a HVAC unit that is shielded as well. The 2 big swinging doors at the rear have a dead bolt apparatus that allows you to lock them once you have entered. In essence you have a double door barrier once inside.
