to vent or not to vent

There are many reasons to leave the doors open when running.

To give the machine cooler air, most small engines are air-cooled.
To reduce the amount of carbon monoxide.
To reduce the smell of engine exhaust/ diesel exhaust/soot (soot will build up on everything around the engine)
To keep the area from getting to warm and possibly affecting any chemicals in the trailer.

I am sure there are more reasons but these should give you some ideas.

I am looking for box trucks and when I put the hot water skid in there, it will be in the back of the truck but I will also have a large fan blowing out towards the back to get rid of exhaust fumes/heat and to circulate cooler air into the truck box. I will look at having some ducting made to bring the burner exhaust and engine exhaust closer toward the back door or possibly swing out when the door is open.
 
That looks very nice Ron.
 
ok thanks for the input i think i will get something rigged up for the burner exhaust. i had originally thought of putting the skid in vertical with truck with burner towards rear gate. but im going to put it in sideways a couple feet in so i can put reels in front of that. I think i would like to try and vent right out the side towards the top no way im cuttin into my roof its fiberglass transparent!
 
I will be installing the hot water skid in the back of the box truck by the roll up door.

I will start looking for 12 volt fans, if they are available, if not then I might have to go with a regular box fan with an inverter, maybe that will work.

Not sure what kind of fans people are using to vent their trucks and trailers, time to start looking.
 
I have a gas engine unit that we have a open vent hole in the roof for when it gets super hot. The fans engine seems to suck air from the opening and then blows it out the roof hatch. Fans really only blow hot air around so you need to get it out.

Running a high-temp vent through the roof has several "NOT so rain-tight" issues involved,
and cutting holes in fiberglass roofs are especially problematic..
Another way..
is to get a "Draft Inducer" from Grainger,
to better "eject" the exhaust out the back door,
and just put a roof-vent-fan in the roof, or top of a side, to get heat out'da rig.
 
Jerry, what about those of us that don't want to cut holes in the side or roof of the box truck, what would you recommend as for a fan or something to get the exhaust out and help cool the box?

Thanks.

Chris, I got a hood made that vents out of my back door. Works slick! IMO it's a far better way than trying to blow out the soot and heat with a fan.
 
Gerald why would your burner be putting out soot?I have mine in a box truck with a translucent top and no venting and no sooting.Just wondering if you have it tuned in right?
 
I wanted to get the heat from the burner and the exhaust from the engine out of the truck but also to help get some of the heat that comes from the engine out of the box also.

I could have some duct made that would work from a local shop once I get the truck and install the hot water rig in there, not sure how much it will be but I think they can make it.
 
A good heating and air shop with a fab department really can do wonders all you really need is 2 45 degree stacked on top of the burner and point it outside the box if its mounted towards the back.A guy that builds some of the best hotboxes you can get said a 90 degree can be to much he said 2 45 s would be better and use stainless steel.
 
Thanks Hal.

I would also like to include the exhaust from the engine into the same duct if possible out the back of the truck.

I have not seen a soot issue on any of the hot water machines I have.

Picture this..
Heater vent running straight out the back door from roof-hanging or wall-supported vent,
..with a draft-inducer helping to push the exhaust out and away from the back of the rig.
And in summer time.. ALSO have a high-velocity box-fan mounted up high, blowing out a door,
..to additionally remove hot air and exhaust fumes from the "enclosure".

These engines y'all run are much better-off with fresh, oxygenated cool air,
just as much as you are.
The air filters getting clogged prematurely are costing you replacement-filter-money,
spark-plug money, fuel economy dollars, reduced productivitry, and reduced profits-per-job.

While you're doing your taxes.. take note..
5% more income could have sent you on a FAT vacation,
or added a new tool for even better profits.
..like say.. a Vacuuming Surface Cleaner. :{)
