Does anyone have or use a oxy tank filling system? need input

[schmoinkel]

Well once again i'm pissed off at my oxy supplier. They were bought out by Airgas not long ago and, long story short, our business relationship has gone sour. Evidently the $5000 a year that I spend with them is not good enough for them to want to keep me around.

Sooo, i'm on the edge of buying one of these set ups to fill my own tanks but haven't heard anyone talking good or bad about it.

It will definitely pay for its self within a year, so thats plus one right there. No more lugging tanks around every week, plus two. I'm sure there are others.

The only bad thing I can foresee is that it takes about 20-30 hours to fill a k tank, witch I go trough about one a day. So the thing is going to be running a lot. I talked to Paul the fellow that owns the company, he said (I think this is what he said) that it draws about the same power as two one hundred watt bulbs and he compared the noise level to his new washing machine.

I would really like to hear from anyone that has any experience with these or this type of set up.
I've just got to get away from these dam tanks, they're a vexation on my spirit and the scurge of my life. (i think i just sold myself right there)

Thanks in addvance.......Scott

oh yeah hear is the link to the one i'm talking about (http://www.dichroicimagery.com/product_info.php?cPath=93&products_id=18136)

You will get some hits soon but I would like to add to discussion these under 5k set ups seem to fill tanks in 20-30hrs can one pressure biulding pump use two ogi 20's and fill 1 every 15 hrs. Is it the oxy-con that need's the rest or the filling machine or both.

can't speak for that setup, i have the setup from OGSI. OG20 and Rix microboost. had it 3 months, i have off and on issues with the OG20 but i think they may all be resolved shortly, will report back in the future.

the two machines together draw just under 1 kilowatt. they recommend you only run it 12 hours per day, so thats 12 kwh per day, you can look at your bill and do some basic math to figure out what your'e paying for a kwh to know how much it will cost you to run this setup. i connect my OG20 and Rix to two K bottles, the more K bottles the lower the pressure, the more oxy you will get out of this system. with 2 K bottles i run this system about 10 hours and get usually around 1300psi, a little over a half a K bottle. they recommend only running it 12 hours a day and only 5-6 days a week so thats right around 3 K bottles a week. it sounds like you use more than 3 K bottles a week so i dont think this system would be enough oxy for you.

it cost me around 7500 then another ~150 in welding fittings, and of course 2 K bottles. energy wise it costs me about 50 bucks a month and i have really really high energy rates (around 24 cents per KwH) in terms of noise its not bad, but not as quiet as a modern washing machine. the piston of the compressor in the microbooster is easily noticed through the walls from my house to the garage. the guys that sleep above the garage hear it when its on, so i don't get to run it at night :(

i actually measured it with a db meter and at 6 feet its about 63 db. hard to describe the sound, but its really not that loud. i live in a suburban area and ive had no complaints other than my housemates asking that i dont run it at night.

pressure matters, filling 1 K from start to finish is hard. i'm attaching a chart that the engineers from OGSI sent me, it shows you that as the pressure in the tank increases the speed this system is able to fill bottles slows rapidly. they only recommend filling to ~1500psi because of this. the solution is simple, use more than 1 tank, at 1500psi x 2 tanks is twice as much oxygen, same pressure.

See here:

i may be wrong but if the flow rate is up to 16scfh, and the og20 is capable of 22scfh, i dont believe you'd gain by adding another og20 since the rix would seem to be the limiting factor there. does that answer your question JR?

[schmoinkel]

Are you saying that your filling two bottles at once and getting 1300 psi in both at the same time?

Thanks for the info n3rd

I forgot to say, it comes with a three year waranty...was told that if for any reason i could not fill a tank he would fix it. I say that becouse I would hope to be able to run the thing every day or as much as I wanted not just 12 hours a day and not have it break down , they have to know people are going to run the crap out of em is what i'm trying to say.

the warranty is exactly the reason i would suggest NOT buying from ABR... but thats just me. how many threads on the shitty ABR service again??

in the 3 months i've had my setup i've needed 4 parts sent to me. i have a poor understanding of how oxygen generators work, so i'm VERY happy i have engineers that work with me and speak my language and send me the parts and help me install them. don't forget you're not only buying a machine that makes oxygen, but the warranty/support too. i can't imagine calling ABR and asking for help with something...

i fill two tanks simultaneously. when you connect more than one tank they equalize, so the pressure is the same in all that are connected. when i say 1300 thats me doing math. the gauge actually reads 650 and i have 2 tanks ;)

i hope i don't sound too biased :p my experience with OGSI has not been 10/10. but the promise of the product (cheap oxygen, at home, low noise and energy consumption, at the pressure i want) is very VERY nice, that and their support is pretty OK. i'm still very happy with my purchase, and i would recommend OGSI to other torchers that have some loot to kick down on the gizmo. but i won't get on a soap box and say they're perfect, however unlike ABR they'll ship it to the right address :bangHead:

[schmoinkel]

I hear ya....hahahah

I will buy directly for the manufacuer Extreme Oxygen (http://extremeoxygenproducts.com/) , there web site is not up to speed yet so i just used the link from ABR cus it had the info and pic. Never had a problem with ABR myself, I only use them maybe once a year if that, but I have read a lot of complaints about them around here.

It does seem to be a new product/company so good good point on the customer service.

:bangHead:

IF gauge says 650psi, that is all you have.... Your math theory is in error. You don't double pressure with two tanks, you double volume. pressure is what gauge says it is, IF gauge is accurate.


Dale

[sertaiz]

but he has two tanks so its the equivalent as one at 1300 just faster to fill.

[atseasick]

not really dale is correct you can not add 650 and 650 psi and get 1300. the volume doubles not the pressure. you are correct in it fills faster though. the more area you add the easier it is for the compressor. the energy or heat of compression is the killer. the higher the pressure the more energy or heat from compression is created expanding the oxygen molecules reducing the volumetric capacity discharged from the different stages of the compressor.

I dont know what booster extreme oxygen use but i have had a little to do with the rix compressor through the navy. they are tried and tested through many years of service. The American Navy divers actualy certified it on release many moons ago il see if i can find the link i found.

So basicaly the more volumetric capacity you have the less wear and tear on the compressor and the faster the volume will increase. Far more efficient to increase the tanks and keep the pressure down.

thats correct. i'm dumbing it down to my level :D

it would be nice if my gauge told me the cubic feet, thats the unit we should use, however we use pounds. both my tanks are filled to 650, and thats the same CF as 1 tank with 1300 pounds.

[jr23]

So 4 tanks each holding 300 would be even better for the machine as far as making it easier on the parts to insure less ware and tear? Or is that a flawed plan.

yes! how much easier? i'll let you know. Kaj has a couple more K bottles for me he said he'll bring by next time he comes to town. it'll happen sooner or later, then another ~$100 or so in welding fittings and ill get all 4 going. i'm hoping it gives me a little more o2 in the end of the day.

I am no math genius, but if I understand correctly. A K tank holds 250 cubic feet of oxygen @ 2500 psi. This is based on stated size and minimum fill pressure according to my oxy distr. So based on that presumption each 10 lbs. of tank pressure should equate to 1 cubic ft of oxy. If that math holds true then 650 psi should equate to 65 cubic feet of oxy.

[n3rd]

you're probably right, however i think a 250CF k tank is 2200psi at least on my regulator.

[schmoinkel]

Paul from EO told me a nifty little piece of info for getting tanks to use with a filling system, he said that he went to a tool rental place and got K tanks for $45 bucks each but the great thing was he will not have to pay till he brings them back, the tanks were probably full too. I have yet to contact any tool places here but man that would be sweet cus you wouldn't have to bring them back till the static test date was up.
You might want to check your local rental shops to see if that holds up n3rd
