Locating MMO coated Ti mesh for Chlorine Generator


I plan on building a Chlorine Generator for a 30,000 gallon pool however I am having difficulty locating a site that sells and ships MMO coated Ti mesh. I plan on using it for both the cathode and anode. If anyone knows a supplier that sells it at a reasonable price I would much appreciate it. Also I have chosen a 10A 30V power supply, however would it be enough?

Edit: I am looking for a supplier that ships to the US



Variable power supply: 0-10amps, 0-30volts

Why not just purchase a chlorinator replacement cell from a swimming pool supplies shop?

Laserred had some not too long ago but he's current;y out. I can't say I am happy as I needed a 2inch by 6in peice with a Ti strip welded on.. I don't have the tools to weld or work titanium but for chlorate anything MMO seems to hold up the best. I hope he sells more soon.

I finally found a Chinese site that sells Ti with MMO, thx for the suggestions though. Also I was planning on using Ti screws with Ti bolts and washers instead of Ti strips to connect my mesh while drilling holes bigger than the screws in the anode and cathode so one screw would only make contact with either the cathode or anode with a piece of Ti strip in between each washer and mesh to improve conductivity with nylon screws holding the plates together. Then I was going to use silicon to seal the space between the PVC pipping and the screw.

Just a few thoughts....

That power supply will have a fair chance of crapping out ( if not your first cell run,later runs)on you with the heavy duty draw that E. cells tend to use. That supply is a switching power supply. What you really want is an analog transformer based supply with analog voltmeters* ammeters. The problem is that you will almost certainly need to build this thing yourself, and its understandable if you can't do that. There is a whole section of this forum dedicated to such problems, in case you haven't seen yet( FYI when you read MOT here, it means Microwave Oven Transformer). BUT since you are not running a Chlorate/Perchlorate cell you might get away with it. Its a risk you may have to take.

How about an old ATX power supply?
Very cheap and compact, no DIY rectification needed.
Most 400W models have over 30Amps on the 12V rails, with ewually impressive amperages on the 5V rail.

That has been the topic of more than a few threads over in technochemistry, and for very good reasons. The PC power supplies provide very stable DC power. This extends electrode life significantly and should increase yields. There is one technical issue that sticks out in my mind asbout them though: to keep the power supply on, a slight load must be kept on a certain color cable( it is a voltage set I can't remember right now) orr the supply will shut off. I think a small light and current& voltage meter display should be enough but , again, its been some time and I would need to review my notes and the threads here. With luck an older member here can link the exact threads but I hope this explains some of it. Mind the Wattages though: Cells needs plenty of power and you still have to watch for the voltage drop a load will inevitably create. I know for Chlorate & perchlorate cells there is an ideal voltage to maintain and it isn't the same for every need.

Thx for the suggestion I found a power supply priced nicely that is also decent quality. However, which cable would I use, would the PCIE power cables be the best choice as they must withstand high end gpu's? Also how many amps do commercial chlorine generators usually draw and what voltage do they typically run at?


Additionally I plan on using a bypass tube for my cell and I have calculated I could fit a maximum size cell 2.1x2.1 inches inside the 3in tube that is 18 inches long. Therefore if I used approximately 1/4 of an inch in spacing between each plate I could fit a maximum of 8 2x18 plates, which probably is overkill.
