We are having some good debate at the moment on set ups and it is inline with what I am doing moving forward.

So here is my ideal set up taking into account this would fit in a Transit 115 with a payload of 1500 kgs

Two Zeta pressure washers with two hotboxes, a shelf above them to hold two cox reels and a 1500 litre water tank.

This would give me heat to two operators, with the flow reduced and diverted back to tank or switching one machine off and using both hotboxes off one machine.

I have had two set ups made that allow me to run two machines into one splitter, with non return valves as a safety option - these could link the two machines together giving an output @ 3000psi on 60LPM and an option to run four men from one van if I need to @ 15LPM

Post your own ideals

Do you mean transit 350 115 ?

[Rob_Mac]

Yes

It will be overweight when full of water but not as overweight as my current Transit & H & M set up is now.

 The transit would be overweight .....£1 per kilo if they catch you. You would have a 1000 kilo's in water to start with. You would need a 5 tonner ...call it plant and run it on cherry!
Could exchange build you a 60litre boiler?

[Rob_Mac]

The cost would be?

Don't know... ask them. http://www.exchange-engineering.co.uk/

I would go for a 40hp+ diesel engine running 2 pumps both on a clutch pulley so i could disengage either pump if I did'nt require a duel operator machine

[Matt Gibson]

Im with Mike on the twin pump idea. Never liked the fact that a single pump split means when one operator releases the trigger the other gets all the flow.

I think my ideal setup would be the one I mentioned in my other post. My existing machine in my van setup as it is (21 lpm) and a hi flow jetter on a trailer with a large tank/genny/twin reels

Exchange wouldn't make one, they weren't interested in making a cover for my 21 litre burner, they only sell covers for 15 litre one's.
I've got one of them on mine with a 6 inch gap at the bottom. I plan to open the top, move it down so it sits on the frame then a piece of chequer plate to box over the top.

[BDCS]

Why noy get a plastic one made ?

Have you got a pic / sizes local guy makes them, think I show one on our facebook page.
With reference to Hot boxes we only use them occasionally, hence hire them in. However we seem to be picking up a fair bit of Graf / gum work at present, hence makes sense to purchase one just wondered...  how do they perform if left unused for long periods, coils etc. It will be stored in our chem store. Thks

[Matt Gibson]

Mike,
 
mine doesnt get used for long periods. its kept in the van as its attached to the machine. starts and fires straight up when i turn it on. burns a bit black for a while but its heats up fine.

[Blast Away]

Just gotta keep an eye on the flow switch now and again, if that goes it will keep burning when off the trigger.

[BDCS]

My flow switch it vertical - I've removed the spring so it fires up on lower flows but the weight of the plunger returns it

[Matt Gibson]

My boiler is plumbed into my machine full time by the looks of it. So im guessing the water is running through the flow switch all the time even when its not switched on.

Does that sound right?

[BDCS]

Yes that could be right - no reason why not apart from reducing coil life

[Mike Halliday]

I removed my flow switch and have the machine solely controlled by the thermostat, I fitted a second uploader set lightly lower so when I release the trigger some water still passes through the burner and back into the holding tank,

As my machine is used for carpet cleaning it helps as my flow can be very small, so small it would not activatev the flow switch even with the spring removed.

Thermostat controll also stops the massive heat spikes you can get when the burner constantly stops then starts.

[BDCS]

I hope your thermostat never fails. So you unload some pressure , hot side of the boiler back to tank ? So this means that the pump is using warm water as feed ? Maybe i've not understood 

[Mike Halliday]

yep you are spot on,

only a pump failure would cause a problem then the burner would be on with no water flow. if thermostat stuck it would be noticeable by a massive increase in temp but I would notice this within a minute
or so and would shut off the machine

it does heat the water tank but never high enough to effect the pump, its only a trickle going back to the tank
