How do I control the temperature of the water in the Electrolyzer, given the electrolytic process is exothermic* and can boil? |
Solution |
*exothermic: Releasing heat. |
|
The easiest way to control the temperature is by limiting the amount of Baking Soda. There should not be any boiling with 1.5 teaspoons in a single jar (12 Volts), or 4-5 teaspoons in each jar when they are in multi-cell (each jar gets only 6 Volts). Unless you've installed it in a really hot area of the engine - .in which case move it to a cooler area, or protect it with some metal shield.

YOU MUST REMEMBER AT ALL TIMES THAT ELECTROLYZERS ARE DIFFERENT. They are not produced by a standardized robot. Any difference in electrode wire, size and density of the spiral, as well as other factors, will change the heat behavior of any Electrolyzer. This means that the number of teaspoons above is VERY generalized. You must experiment to find the safe limits of your own system. Also remember that the vehicle itself, and every location in that vehicle, has different heat factors (temperature and the ability to dissipate heat and get rid of extra hot air) as well as magnetism and vibration. All these factors will make different safe points even with the very same Electrolyzer. |

Another way to reduce the heat is to build a Multi-Cell system if you're currently using a single jar (see User Manual Chapter 14, or DVD 4). You have to understand the purpose here. The main reason for a multi-cell is to produce more HHO and save more money on fuel. In which case you would probably want 4 or 6 cells (jars). However, another important reason is to REDUCE HEAT thanks to the 6-volt operation instead of 12-volt operation. In which case even adding just another single jar would do the trick as far as reducing heat. |
|
To achieve this effect, the second jar must be connected in series, and the amount of baking soda adjusted accordingly to 6 Volts (see book/DVD for details). |
|
One last popular way worth mentioning is to use a PWM circuit. PWM means Pulse Width Modulator, and is an optional electronic device that controls the amount of power delivered to the Electrolyzer or Multi-Cell system. A regular 12 Volts power source is connected at the input of the PWM, and the electronic circuit changes the ratio of ON time to OFF time (controllable by a knob), thus creating an effect of reduced overall energy, over time in general, delivered to the Electrolyzer. Another good reason to use PWM in HHO production is to excite the electrodes many times a second, resulting in a more efficient, less heat producing electrolysis. |

PWM circuits are available on our website and others, with or without a box. Just make sure to select a circuit that can carry the current required by your Electrolyzer(s). Take a safety factor of 50%-100% because these babies tend to heat up very quickly. For example, if your HHO system draws 15 Amps, use a true 30-amp circuit. By 'true' I mean that it can provide 30 Amps continually and under harsh ambient temperatures, not momentarily in a cool lab. If the safety margins are small (you'll feel the heat sink heats up almost too high to touch), add a cooling fan above the heat sink and close to it. |
