6 Redmax torches on Concentrators and Natural Gas

[Glassroots]

I'm looking to run 6 red max torches on concentrators with a pressure tank AND Natural Gas at 5psi. Does anyone have experience with this type of setup? From reading on the forum it looks like I would need 3 concentrators per torch.

Sounds like a good start.

There are several ways to do it.

More storage tank capacity volume vs pressure.

Slightly higher pressure for extra volume.

Somewhat depends on the worker and there torching style.

With a good amount of storage in a tank, you can get by with less lpms.

For a hard worker I'd say 70% of the torches consumption, with 30-60 gallons of holding tank space.

That would keep you pulling stacks all day!

That's on the o2 side. I'm not familiar with natural gas

6 red maxes would want a good dose of natural gas, You can call the natural company, most the time they will upgrade the service and stick in a bigger meter and regulator, may want to pipe in a bigger pipe like what a pizza restaurant or small laundromat would need. Boost pressure and the bigger pipe for volume, not huge but more then normal households, run you a 1-1/2 -2 inch pipe or something at 5-10 psi. The natural gas pipelines in the street are at a higher pressure so it feeds everyone good. even in my residential area the engineer told me the pipe running down my street is at 55psi.

Good choice to go natural gas, propane needs 2.5 times more oxygen then NG, you use twice as much natural gas due to the BTU factor so oxygen use stays the same pretty much, the biggest factor is its 10 times cheaper then propane.

As far as oxygen to do a HVLP you will want a huge tank and lots of concentrators. In that scale you can get kick ass compressors with horsepower so it would rock if you can get enough concentrators, like 60 lpm+. a 500 gallon tank at 100 psi is not even as much as 2 k tanks so think about that, about 12,000 liters and 2 k tanks about 14,000 liters. you need to do the math along side some actual usage data.
You can regulate in some supplemental oxygen from a tank if you draw the system down too much.

Running 6 torches is not that big a deal but it is when they are inefficient torches.

12862.5 liters...lol 500 gallons @100 psi room temp

yea I know, its not very much when you think about it.

3 feet round by 10 feet. big shops with big air tanks tend to hang them from the ceiling.

Only $2,000. weighs 1,100 pounds.
