Hello @user-cd7cg6ez1b, we will be happy to share our plans with you. We recently shared an email with a viewer, and it may have been you, showing how we built our Nitrox Stik. If it wasn't you, send us an email to info@lakehickoryscuba.com, and we will be happy to share the plans on how to build your very own.

I love the setup you got. I have the same compressor. But where did you get the blending tube or the kit? Did you make it your self? I live 5 hrs away from any one that can blend. I would love to put together my own blending set up and I like yours. I’m an instructor. I’m a tech diver. I have done a lot of nitrox fills when I worked for a dive store, but we pre blended in banks. Now that I’m on my own I would like to put together a kit like yours. It’s perfect for just me. Nice video by the way.

Hello yann devouassoux, this was one of our old back up compressors that we have now replaced. The Blending Stick was made by us, and is very simple to do. Send us an email, lakehickoryscuba@gmail.com, and we can send you the plans on how to make your own.

I watched your new cylinder prep video where you covered your cascade fills. Since you bleed down one customer cylinder to another to equalize all cylinders being filled is there a risk of someone having a cylinder that was previously filled with a higher O2 mix than air messing with the other cylinder being filled where their air MOD could be affected? Obviously we check mixed gas fills, and I’ve caught bad fills before (27% that’s should have been 32%). After that I also started checking air fills just to be sure that there wasn’t an error filling them.

Hello Caleb Mcelhaney, our fill operators are trained specifically on our fill stations, and for any mixed gas, they verify all mixes after the fill. Top offs as some would call them, can cause certain mixtures to be wrong. This is why all of our fill operators are required to go through the SSI XR Gas Blender course and they routinely get trained in compressor maintainence as well. Customers are also required to verify fills prior to leaving with their cylinders. We encourage all customers to verify even their air fills prior to diving.

Hey Darren Gibbs, not sure what is going on with my email, but I received on the company's and have responded to it. There are plans and pictures attached. Hope this helps.

How much does the air flow through the stick (and therefore the amount of O2 you have to add) change as the tank fills? I'd assume it slows down significantly as the pressure goes up. Also how do you like that QuickStick analyzer? I've been thinking of getting one just to double check my own tanks.

@diversdown2116

4 жыл бұрын

it does not change. the compressor runs at a constant rpm so the inlet takes in the same as if it is at 100psi as it would at 3000psi the only time they mess up is if your O2 reg is bad or the compressor belt is loose but that should not happen with a proper look over before you use it. i added a solenoid valve to shut off the O2 when the compressor shuts off or losses power. just so no O2 builds up. a pure O2 hit in the compressor could be very bad

Hello Dan Bowkley, b st john explains it very well. The intake can only take in so much air at a time. The micro adjustment on the O2 cylinder only controls how much O2 flows into the Nitrox Stick itself. As far as the analyzer, I have used just about all of them. They all work great, this just happens to be the ones I am using now.

So do you prefer to add compressed O2 rather than use a membrane type system? When would you use one over the other?? Thanks!

@LakeHickoryScuba

Most shops will either use partial pressure blending or continuous blending method due to cost. Membrane systems tend to be more expensive, and most shops choose not to make the investment upfront.

Hello lee Owen, glad you liked the video. I am very familiar with a membrane compressor system. Outside of visiting shops that use them, and playing with them at DEMA, the big diving show each year, I have never owned one. We recently purchases a new compressor a few years ago, and was considering getting one. We opted out for several business and financial reasons.

Hi there Quick question, why the analyser before the compressor was reading 31.3 and after filling was marking 29.9 And should you leave venting a bit before filling the actual cylinder? Thanks in advance Manny

@LakeHickoryScuba

Hello @user-he8hy2cc3t, the short answer here is Charles's Law. Partial pressure will change as temperature changes. During the filling process, the gas is heated during the compression stage, and over time will cool, thus losing pressure. When this happens, mixes can change.

Hey brian. That’s a brilliant idea. But what happens if the oxygen is contact in with oil inside the compressor Does it not initiate flame hazard?

Hello David allen, we have several compressors. This is the one we use for Nitrox fills. We have a much larger Bauer that we use for most air fills. It has 4 cascade cylinders that we typically will fill from.

Bryan - I enjoy your videos. I don't mean this question as a "gotcha" one--I just want to see if I am missing something. I assume the process of filling the tank in the video was a continuous one and so what you set the initial fill for the stick is what you should get when you do the final analysis with the hand-held sensor. Given that assumption, I didn't understand why the locked in pressure on the O2 sensor was set at 31.3% (7:00 minute point on the video) while you later said it measured 29.9% (9:00 minute point). Did I miss something (sadly, not a rare occurrence!)? Thanks.

Hello jbunderwaterservices4132, from the beginning of time (the beginning of the scuba industry selling mixed gases), there has always been differences in opinons on using Oxygen Cleaned Cylinders for anything other than standard breathing gas 21%. Fill station operators are required to abide by DOT and CGA gas laws in the United States. Most shops (non International Training Shops) that are certified through PSI / PCI, will require cylinders to be Oxygen Cleaned for any gas mixture above 21%. What you are referring to as Nitrox Cleaned is not an accurate way to describe the actual cleanning of the cylinder. With Oxygen Cleanning, the entire purpose of the process is to eliminate all hydrocarbons from the cylinder. Once this is complete, as long as Modified Grade E Air (Oxygen Clean Air) is used, the cylinder will remain Oxygen Cleaned until the cylinder valve is removed. Once atmospheric air is re-introduced into the cylinder, it theoretically is no longer Oxygen Cleaned. Now the argument we here all the time is, if you are using pre-mixed or pre-blended gas mixtures (in short a Nitrox Stik mixing station) then the risk of the fire triangle occuring is limited to the point, the fire hazzard no longer exist. Only during the mixing phase of partial pressure blending, does the fill operator have a substantial risk of injury. Whether a fill operator follows this way of thinking or not, he or she is still bound by the insurance company that covers the shop, and the current DOT and CGA gas laws. Thus, they follow the rules. The simpliest solution to not have to worry about the shop giving you any hassle is to buy a small compressor and building your own Nitrox Stik for practically nothing. I have built them in the past for less than $100. You can pick up a small compressor for around $2000. Thus, for $2100, this would be paid for after about 210 fills, not including filters, oxygen, and normal maintainence fees.

@@chrispayne806 It seems you're confusing two things. There's only one compressor in the video: the blue Bauer Junior II. That's what compresses the gas into the cylinder. It pulls in gas through the yellow/green Nitrox mixing stick. The stick has two inputs, air from the tip and pure oxygen on the side from that big cylinder (which has a pressure reducer on it, a simple regulator valve). Inside the stick, the air and oxygen mixes and a nitrox analyzer at the bottom of the stick gives the operator feedback so they can adjust the oxygen input flow to get the desired mix on the output. That output goes straight into the compressor and from there into your cylinder.

Is your compressor compatible with O2 over 21%?

Geez you are doing it all wrong, everyone knows you use BLUE masking tape. LOL One danger of a cold cold fill is that the pressure can shoot up if the water is warmer. I remember a cold day (well for Florida at 60 degrees) I setup my tanks, and put them in the spring water (at 72 degrees) when I went to put them on they went up another 250psi.

@LakeHickoryScuba

Thankfully Charle's Law plays a big role in the matter. For every 1 degree temperature change, your PSI will either raise or lower 5 psi. With this being said, most valves are rated to 5000 psi, as is the test pressure of most standard 3000 psi cylinders. So the likelihood of a cylinder being jeopardized by an over fill due to heating up, is highly unlikely.
