8GPM Pressure Pro Cold Water Charging system for Hot Box

Use a large battery and maybe get the cutoff ignition that stops the igniter after the flame starts.

Anyone running a 12v Largo with a Pressure Pro 8GPM washer?

Matt, any particular reason you're wanting to go the 12v route as opposed to the 115. I bought the Largo 115, 8-12 GPM horizontal hotbox and will be using a stand alone generator (Generac 3300 watt). There must be pros and cons to either route.

If you're wanting to run the 12v hotbox off of the Pressure Pro 8GPM do you have the Honda GX630 or GX690 engine? I have the Honda 8GPM with the GX630 engine and just did not want to sacrifice any horsepower that would be needed to power the hotbox. Maybe the GX 630 will handle it but I feel better with the 115v hotbox with separate generator for powering it.

Keep us posted on which route you take. Good luck with it whichever unit you choose.
 
I just re-read your original post and see that your machine has a GX630 engine. Won't you need at least a 20 amp charging system as opposed to the 17 amp? I'm sure others will chime in with info about whether this will work or not.
 
The ADC burner won't make enough heat for 8 gpm. The SDC will heat the water, but uses every ounce of power coming off the engine's charging system. If the smallest thing goes awry and the voltage drops off at all, the ignitor will have a melt down. You'd be much better off with a 120 volt hot box and a generator as Rick said.

Yes. From what I ubderstabd it needs a 20 amp. I researched this weekend abd couldn't find anything to confirm that it is the 17amp other than the "20amp was optional". apparently the 20 amp has a 40a fuse whereas the 17amp has a 30a fuse. So I will probably check that for confirmation this afternoon when I get back. Maybe I'll go the 115 and generator route. My rig is Just very tight on real estate.

I feel ya on that note. My trailer is 6'x12' (formerly 14'x6') tandem axle that I cut two feet off of the back so it would fit in my enclosed garage and still have room for 55 gallon drums of bleach on the garage floor. My trailer is pretty tight with 225 gallon water tank, 35 gallon chem tank, stand alone generator, 8 GPM and 4 GPM pressure washers, 18 gallon gas tank, two stacked Titan reels, one Cox reel for spare hose, 6'x2' toolbox, and now an added Largo horizontal hotbox.

Yeah, I really needed the vertical hotbox due to lack of space but preferred the horizontal for stability due to lower center of gravity. It all actually fits just fine and is laid out to be very easily functional with room to access any and all equipment on the trailer.

You could change out the stator in the honda for the 25 amp

What are min generator requirements if I go 115v. Trying to measure.

Some guys say that a 2,000 watt generator will work but I got the 3,300 watt generator. Starting up requires more power, then running after start-up the power requirement is much less. I would not go less than 2500 watts from what I've read on these forums. Also, if you ever need to run extra lights for nighttime work the bigger generator will earn its pay. You can even use a small microwave to heat up a meal since you can't leave the work sight without rolling up hoses and packing up equipment. To me the stand alone generator has benefits. My Generac 3300 will run 10.5 hours at half power on a single tank of gas so that covers an entire work shift. The tank holds 3 or 4 gallons so that's not too bad at all. Besides, the customer is going to pay for all of my fuel and gas anyway.

Another thing, if the generator was to fail you can always get a replacement by renting or even going to Lowe's and buying another one if you have to. You won't have to dismantle it from your hot water skid or take the entire skid to a shop for repair. There may be some disadvantages with the 115v hotbox and generator but there are plenty advantages too.
 
Matt, when you go shopping for a generator it's a good idea to take a good look at it to see where the muffler exhaust exits the motor and also where the starter rope is located. May sound stupid but since you're gonna be placing the generator in a tight spot you'll still need access to the starter rope (if manual start) and plenty of room for the exhaust to avoid other objects on your trailer. I only say this because I had a time finding the right spot for my generator that would allow access to starter rope as well as ample space for the exhaust to exit the machine.

If you can afford one of those inverter generators they are smaller, lighter, and use less fuel. You could probably just transport one of those in your large tool box and not have to mount it on the trailer. But they are quite pricy.
 
I understand the pull cord location... I have a scare from a washer mounter with a tuff pull cord shut off location ( had a hose burst and was tying to shut it down when my foot slipped and the corner of the diamond plate tongue box punctured the skin just below the outside of my lower leg bone below the knee...) I looked at the inverter ones.... they are pricey........ but so is everything......Northern has a knock off brand for half the price of a Honda... Obviously they have a smaller foot print or overhead print... deeding where it is mounted... I assume they are just as durable and perform the same as the bigger ones on wheels etc..
 
What is an inverter generator?
 
2000 watt peak inverter generators is what I have used for close to 5 years now. I have had the largo big burner (says 8-12 gpm, really max is 8 gpm) for 4 years running off these small generators. Start the inverter up, give it 30s - min of warm up, switch the burner, turn it on eco mode and work for 10 hours on a gallon of gas.

I would recommend 120v over 12v in your situation, also would keep in mind with the bigger burner you can drink diesel quick. Turning the heat up, I can run through a tank in 4-5 hours no problem, keep that in mind if you are using lots of heat, you will need some extra diesel.
