What's the internal blower plumbing set up like? Does it come with 2.5" ports. And what kind of heat can it maintain with 1.5 gal per min flow constant, and what kind of heat can it keep with a spinner...I'm sure it can't handle two spinner heat wise for tile though. How does the heat exchange system work? What kind of fuel efficiency numbers would one be looking at?
The internal blower plumbing exits the blower then goes straight into a large bore blower exhaust heat exchanger and then from there flows through 2 x 2.5" mufflers upon then exiting the machine.
As for what heat can it maintain, at 2700 rpm it will easily hold 235-240 with a wand with 6 gpm jets. But your probably never going to run that engine at them revs constantly unless you are doing external hard surface cleaning, dual wanding or flood restoration.
I honestly did test the unit myself at lower revs, but I rang out client today that purchased this machine and asked him his thoughts. He is, or was a
HydraMaster CDS user. His
CDS machine in under 3 years old and has the salsa heater pack as well. He said at 1500 rpm, the Diesel Genesis was as hot as his
CDS, but has A LOT more vacuum in his words. He also said at 1500 rpm, it was quieter than his
CDS. He was quite impressed thus far with his new toy.
I agree with you though, due to the flow (unless your going to purchase an after market diesel burner or LPG setup) nothing is going to keep up with sub 240 deg temps with 2 tile cleaning spinners. It will however with 1 tile cleaning tool, hold very good temps still. You still will get temp with two tile tools, but nothing exciting I don't believe.
Bear in mind, from memory, a Diesel engines exhaust temp is around 800 deg F, whereas a gas engine the same size is around 1200 deg F, so the Diesel's aren't going to have as many burnable BTU's and therefore not feed the exhaust heat exhangers with as much heat. But what they slightly lack on the heat department, they more than make up for on the torque, reliability and longevity over the gas engines.
Rather than quoting something inaccurate, I will put them up after the weekend when we can calculate it and let you know real world figures.

Looks great. Can you take out the blower filter and take a pic? You guys said at Connections that you were working on an external SS debris filter like the one used in the trucks down under. How is that going?
Hi Lance,
Did you want to see in behind the blower filters? If so, I can do that a little bit later on. We have a third of our state under flood at the moment, and the client that owns this rig is flat out working. I will take you some photo's shortly however. The boys are PowerClean USA are working on a pre-filter like the one pictured. I don't know how theirs are going over there as I am from 'down under' and this is the one that we manufacture

looks good Jim, thanks of sharing.
tell me, what's that ball valve and port under the vac ports?
It that for the pump out?
also, what kind of heat does it maintain when running in single wand mode?
(1500rpm)
lastly, is the 125 gal waste tank a "usable" 125 gal?
Reason I ask that, word on the street is, the gas Genny waste tank starts sucking water thru the blower well before it's rated waste tank capacity
ps..hope to hear the GPH fuel usage that Tim asked too.
i hear the GPH on the gas Genny is in the 2.5 to 3 gph range.
Diesel fuel typically runs .25 to .35 cents per gal more than reg gas in my area
..L.T.A.
Larry, the ball valve under the 2.5" vac ports on the waste tank is part of the self cleaning waste tank system. It has a large filter basket that sits directly above that tap inside the tank. It has a shelf in there that collects any of the debris that comes through the bottom of the filter basket, so when you start the self cleaning system, a lot of the heavier debris will collect here and is easier to wash out of that shelf, than getting caught and having to try and wash it out of the bottom of the waste tank. There is also a flood jet that pushes from the back of the tank towards to big on/off tap down the bottom of the tank as well.
In regards to the waste tank size, you are correct. It is not "usable" to 125 gallons. But then again, no TM manufacturer (to my knowledge) ever quotes usable. The quote overall size and vacuum. Just like blowers. Manufacturers do this, I think not to misinform, but rather as a benchmark. The waste tank on the gas Genesis, just like the Diesel Genesis, and the same as the
Prochem and
HydraMaster waste tanks never will get to 100% capacity before the high waste water shut down kicks in or the APO float switch engages. But it won't suck water into the blower on the PowerClean machines or any major machine manufacturer for that matter (unless someone disconnects the high waste water level shut downs every manufacturer uses in the waste tanks). It may however, suck through some foam if it is floating around inside the waste tank. I will also get back on here as I stated above and post the diesel consumption.

The new location of blower filters should be much more convenient and add greatly to the usable space in the tank but I don't see why the filters will stay any cleaner. Won't the air flow just carry debris further down to the filters?
I think the cleaning jets in the bottom of the tank is a great idea. Do they actually get the gunk out the drain?
By the time the waste gets sucked through out large pre-filter and then through the standard waste tank filter, there is hardly any debris that enters the waste tank. But you are right, you will still get some, but nothing like a standard slide in waste tank with 'in-tank' blower air filters. And yes, the wash down waste tank jets to a good job, but bear in mind, most of our heavy debris is caught in the external filter first.

Larry......the Genesis doesn't have a lot of usable waste tank, and it does start sucking water IF your APO isn't working right. (or you forget to turn it on)
The Genesis is no different to any other slide in waste tank as I stated before. I am puzzled though how you mentioned your Genesis sucks water through the blower. Have you checked your high level shut downs. If they are routinely cleaned and tested, there is NO WAY water can flow into blower. As I wrote above with in Larry's reply, most blowers will suck foam/moisture if there is some in the waste tank. I normally see this if one of our customers is using a cheap and nasty prespray that has excessive foam.
Since you already own a Genesis (how old is your unit by the way RW?), you would have noticed in the photo above that PowerClean is now utilizing a larger and more industrial APO system. Under full vacuum load, this thing really pumps that large tank out quite quick. We were impressed.

Looks cool! what are all of the qd's on the from for? What is the expected price for the u.s. gonna be?
The large S/S on the bottom left if for incoming water. Because the Genesis runs a multi-temp cleaning system, that is what these are for. One Q/C is for cold water, another for warm water, and two high temp, high pressure Q/C outlets.
I am sorry, I don't know what the price is over there in the USA, but your nearest PowerClean distributor will be able to inform you. If not, Larry, the director of sales for PowerClean could shoot you an email.

What is the Valve in the middle of the dump tank for?
Hi Scott,
I mentioned this in Larry's reply. It is part of the waste tank wash down system.
Thanks for the questions/input guys. We appreciate hearing real cleaners questions and concerns.
Have a good weekend everyone (it is Friday afternoon over here so I am typing this from the future)
