I have a NX fill station with the nitrous filter, air/water separater, and digital scale. I have it all hooked up in my living room with the mother bottle(siphon tubed) just a few inches away. I plan on selling refills to the racers in my area, but I'm new to this process. I'd like to be as safe as possible aswell as give my customers what they paid for.

Question 1 - Do I need to heat up my mother bottle? I have a small household heater that I could use. I know I need to get a pressure gauge too.

Question 2 - Does the temperature matter on the bottles I'm filling? Should I chill them? They'll most likely be warm from the hot Texas weather.

Question 3 - Will the pressure be too high if I'm filling a half full bottle that's kinda warm already or one that already has a lot of pressure? I'm worried that when I add to the bottle, I'll exceed the max pressure and I'm not sure if many of the racers down here install burst discs.

Question 4 - Should I offer to freeze-fill for customers who don't mind waiting(if I have the space in my deep freezer). It only takes a couple hours right?

I'd appreciate any help or advice ya'll could give me.

Maybe call a trusted sponser and ask them those question, i am sure they wouldn't mind helping you out.

You have a 100 PSI air source to function the Pump?

I am setting up to do the same thing, just waiting on my bottle stand for non siphon Mother bottles from Chris @ Nitrous Outlet.

Gonna do what the other shops do, look for the MT weight on the bottle and add 10 (for a 10 pound bottle) to the fill weight on the scale (or ensure bottle is empty weigh it, and add 10 for fill weight).

Spraying will be enjoyable now that I don't have to drive two hours round trip for refills!

Yeah, I have a big compressor to feed it.

I figured that's how it should be done, but I wasn't sure. I was reading all these topics about people getting air instead of nitrous, or exploding bottles. Then some guys were saying they wouldn't even go to a shop that used a pump rather than a freeze-fill.

Racers around here travel about that far to get their refills too. Hopefully I'll be the new "source" for refills down here.

do you have to have a license? where do you get the nitrous from(supplier)? All they do around here is freeze fill them out of a 5' deep freeze.

No, you don't need a license. You should go to some of the welders in your area and ask them where they get gas. Or go to your local H.E.B. - find out where they get their gas[helium] and dry ice. Then call that company and see if you can place an order and pick it up when H.E.B. gets theirs.

Pumps are a bigger PAI IMO I do not use one at all.

I keep the mother bottle in the garage put the smaller bottle in the freezer for 20-60 mins just depends on temps and fullness of both botles.

Be careful it is easy to overfill a bottle using this meathod I will put 11-12lbs in my bottle but only 10 in others. Most shops around here will only get 8-10 lbs with a pump.

I came home with a full 7lbs once

I tell my friends to freeze/chill there bottles b4 they come if they can.

Keep track of what you use you get ~45-50 good easy fill lbs from a 55-60lb bottle, I use the last 10 for my self as it takes longer to fill.

BTW way why would you do it in your Living Room?

NO

Question 2 - Does the temperature matter on the bottles I'm filling? Should I chill them? They'll most likely be warm from the hot Texas weather.

Yes and Yes

Question 3 - Will the pressure be too high if I'm filling a half full bottle that's kinda warm already or one that already has a lot of pressure? I'm worried that when I add to the bottle, I'll exceed the max pressure and I'm not sure if many of the racers down here install burst discs.

It can be but since I dont use a pump mine never are.

Question 4 - Should I offer to freeze-fill for customers who don't mind waiting(if I have the space in my deep freezer). It only takes a couple hours right?

Yes and no
I would tell them the colder they bring the bottle the better and faster the fill.

It's in the living room because we didn't have anywhere to put it. It's a small house and it's setup kinda funny. My wife doesn't mind it and nobody ever comes to my house anyway.

So are you guys that do fill and freeze just running a direct line from the mother bottle to the reciever bottle?

The pump type work perfectly fine, you jsut have to have the bottle on the scale, and keep pumping until the thing's up to 24 lbs for a 10 lb'er

SY732

All the setups I have seen do.

SY732

But dont let it get too hot...but why would you stop at 24 I always freeze and fill mine to 25-26.

because the bottle is designed to hold 10 lbs of notrous, NOT 11 or 12... that's probably the first reason.

#2 is consistancey, start filling bottles too much and it's gonna **** with your tuneup.

If you're just goofing on the street and not actually racing for real, I guess it doesn't matter though
