Swamp coolers collect and breed all kinds of bacteria and mold in the water. As the cooler operates, these organisms can travel into your home and ca...
You will need a 1N4005 diode and a 62k ohm 2 watt resistor to make a pulsing DC power supply
Mount the diode and resistor on a piece of perf board. The band (cathode) of the diode should be toward the left. The direction sets the polarity.
Be sure to observe polarity of diode. The line cord is soldered at the resistor end and the electrode is attached at the diode end.
Don't forget to solder the joint between the resistor and the diode.
Cut off the plug end of a line cord. Cut the green ground wire and the white neutral a little shorter that the black (120V hot). Strip only the black...
Solder the black lead to the resistor end of the assembly.
Solder to the diode end a length of wire with a quick disconnect female connector.
Check your wiring and cover with two layers of heat shrink tubing. I used "sticky shrink" (the type with hot melt glue) on the final layer. The stick...
This is what it should look like. The generator is ready to have the electrode made.
Attach a length of wire to the "electrode" with a pipe clamp to a 4 inch brass nipple with 1/2 inch inside diameter or larger. Use a heavy gauge wir...
Attach a male quick disconnect connector to the other end of the wire.
The completed ion generator with wiring ready to install in your swamp cooler
Place the electrode in the water and plug it to the power outlet inside the swamp cooler. I modified the outlet so continuous 120 vac is supplied to ...
The electrode can be placed near the intake of the water pump to allow water to flow though the pipe. Because the bottom of my cooler is epoxy, the ...
Over time, small amounts of the brass will enter the water as ions of copper and zinc and will attack the mold and bacteria. Measured current of .89 ...
This Project at my websiteWARNINGUse care when handling the device when on. Remember the device is connected to the mains.Current is limited, but a sm...
