Looking for Info on Parts Cleaner

I am not aware that the EPA endorses any products of this type.
Nor do I know of any web resources on the system one parts washer.

This is what I know based on an intern project that tested it:
The equipment is a variation on a tub-on-a-drum parts washer that has a 
solvent still built into it.
It typically uses mineral spirits as a solvent although other solvents or 
cleaners might also work.
If mineral spirits is used it is no friendlier in terms of worker exposure 
than a Safety Kleen parts washer
or any similar washer, unless a soil being removed is an exposure risk.
It is onsite, closed loop recycling, so it removes some of the 
transportation hazard compared to
typical washers, and some exposure hazard compared to the use of an 
external still onsite.

In practical terms, the washer worked well, and impressed the users in 
terms of ease of use
and solvent cleanliness.  They found the solvent reservior to be small, 
such that it needed daily distillation to keep up with a heavy work load. 
 The unit was also relatively costly.
The intern host determined that a parts washer with fine filtration 
-lengthening solvent life - made more sense for them.

P2TECH folks --

As someone working primarily in R&D,  I usually find myself safely 
from the real world (and, perhaps more importantly, the real world is 
insulated from me!).

On occasion, however,  I end up at the receiving end of actual technical
assistance requests.

This is, of course, a clear indicator that there are people in industry who
are truly desperate for help!  (But you knew that already).

As a case in point, I received the following request today:

			"I am interested in finding out some information
about a particular parts cleaner for industry that is supposed to be more
environmentally friendly than its competitors.  It is called System One. 
you tell me if the EPA endorses this product or if they have any 
about it?"

In an effort to find information on this product, I've checked the usual
suspect sites (DLA's Environmental Products Catalog
http://www.dscr.dla.mil/products/epa/eppcat.htm, Envirosense's various
search functions http://es.epa.gov/,  Thomas Register
http://www.thomasregister.com/, WRRC's large document collection at
http://www.p2pays.org, etc).  Can't find the aforementioned "System One".
Hence this request.

Information on either the product and/or on specific search strategies for
alternative cleaning technologies & products would be welcome.
At one time I was familiar with a lot of what's online,  but with new
resources becoming available daily, it never hurts to ask.

Thanks in advance,
