I was over at that site doing some homework and on 7/19/2002 M. Stillwell[epps] and John [envriospec] had some stuff to say about there products.
SEVERE DUTY was the title.
I wish that thread were here.
Two intelligent people with diffrent idea's on how to get better result's.
They stopped that thread too soon.
I would like to read more from them on that thread .
Also this opens the door to JOHN to talk about the new FIRE CANNON-ALL STAINLESS PW
Seems this unit is going to raise the bar on skid units as well as price.
two-20 gal fuel tanks!!!!!
optional water cooled engine.
optional dual gun set-up[two units in the space of one]
Tell us more JOHN.
P.S. post it in the correct thread, not here.
 
Better ask him directly. John does not want to or will not post here for some reason.
 
Ron, I also seen that unit with the dual wand off of one machine...

The question really came to me when, I was pricing two machines...
What happens if that one machine fails, you are out two machines with out having two ... To me it still makes more sense to buy two machines, instead of buying just the one... I would like to see the weight, machine verses two machines...

I prefer having two independent machines, in case something goes wrong with one, I still have another. It really depends on your vehicle though, for the right application, two guns from one machine would be great.

John Allison, you're welcome to post on the bbs any time you want..........as was said above, please keep any direct product references or advertising in the distributor sections.
 
just think

of how nice it would be to run a 48" surface cleaner with 10 gpm HOT.
I would have my current unit as back-up.
There is something about a possiable 50% trade in?
So Mike if you were into flatwork you could trade one in for 50% off a dual machine and still have a back up.
My question is where do you get the water supply from for a 10 gpm unit?
Not everyone has trucks like Mr Olsen.
I dont understand why e-spec would try to market a unit like this? Who on any of the bbs can steadaly supply a 10 gpm wash unit?
Am i missing something here?
10 gpm a 500 gal tank and a 5 gpm spigot hooked to the tank. What is your run time? 75 min.?
unless you use a fire hydrent,have two sep. water spigots,or have 1000 gal of water on board you cant get a large shopping center done without stopping, correct?
 
I just read about a Powerwashing Company that is based out of Florida. They have around 7 Employees and they do mostly Commercial Cleaning. There machines are rated at 12gpm. They clame because of the large GPM they can clean real fast.

I would Imagine that they have at least 500gal water tanks that they show up at the job filled up. Then they probably hook up to the bldg's water spickot where the water is probably coming out at least 8gpm(This is a guestimate but the commercial work that I do even though I never really checked the gpm's it is definitely much higher then the average residential gpm's which most of the time is about 5gpm's).

So if the above is the case then they should have no problem running those 12gpm's PW's. It all makes sense to me and we can all agree that GPM's are a major factor in cleaning. If I ever become more successful with my business I would look to have a much greater gpm's coming from my PW's then the 4 & 5's I have now.
 
I agree with the two machine idea. However, you may want to check out some of Greg's posts on his board about the same issue. He was looking to go to a one machine 2-gun concept to save space in his vehicle.

His logical was pretty credible.
 
On PWNA bb There is somebody selling a pretty new Allison 2 man PW and New Dual Axel Trailer with a bunch of extra's(Tanks,wands etc.) Asking price is $9000. I'm sure if anyone really wants it they could negotiate that price down some.
 
More GPMs = clean faster. Are you really using that much more water then?

1 hour @ 5.5 GPM's = 330 gallons
40 mins @ 10 GPM's = 400 gallons


not much of a difference.
 
A couple comments since my name was mentioned.

When considering higher volume machines be sure you are comfortable with how the machine regulates the flow of water and heat to the burner. If you want to operate at reduced flow the burner must be able to detect that and not super heat the water. I say this because I had a boiler (brand new) that could not handle the variable water flows that we run (of course the salesman said it could before we had it installed)!

The reason I point this out is the machines that we looked at a few years ago, the burners were set up to either be on or off. So when you operated at less than full water volume the water temperature would/could exceed the set point considerably. In my case I wanted 180-200 degree water and got well over 300 degrees!

The folks that we bought it from took it back. I ordered a different boiler (another manufacturer) that can handle our type of operation much better. Our new boiler has a modulating fuel valve to control the flame in the burner. We also have the capability to make steam (when and if we want too)! We routinely run (while on the same job) variable flows. Since we have ball valves on the end of our hoses we can and do run any flow up to the maximum of our pump.

If I were in the market for a new machine like the one you are describing I would expect it to have at least a 1,000,000 Btu burner, a liquid cooled engine and run on a single fuel, Lp or K1. I would prefer Lp.

I don't own a hot water machine ( will be purchasing one), but I have had nightmares about just what Dave described on the 2 gun units. I have always wondered how much downturn (in flow rate) both the heating system (burner) and unloader have. I'd run the machine for an extended period of time before I took it out of the supplier's shop.
 
High volume machines

I run two diesel 10 and 12 GPM pressure washers all day long. They take two water spigots and three if you have the access. Meyers pumps and clean as fast as you can move the wand. Water volume always is king and we use around 1800 to 2000 psi to clean buildings, drives etc. These are cold water machines and we don't have a great need for hot water in our business. But a burner that will keep up with this volume is something I would be interested in soon. Keep cleaning, it was cool in FL today 55 in the am. I will have to buy a jacket if this keeps up! Jim
 
Jim, you wouldn't happen to be related to a Mike Twist in the Northern Miami area would you? Also, I used to live in W. Palm about a year ago. Worked at Rachel's and Diamond's.
