The PWM has become the new standard of current
control for advanced HHO Kit enthusiasts. Rather
than just straight current flowing into your generator (Brute
Force), these PWM boards control a "Pulsed Current"
by pulsing off and on rapidly. Some pulse at a fixed frequency,
and have current adjustable. Others allow both current
and frequency to be controlled. Some argue that the frequency
is critical, but we have found no evidence that it makes any difference
in all of our testing.
is a definite advantage though, to using a Pulse Width Modulator
to more precisely control the current to your HHO kit. You may
find that best mileage is at 17 amps, or 22, or 25...etc. Having
that extra control makes it nicer for dialing in your HHO generator
to the perfect setting.
I NEED A PWM?
That is a common question. If your HHO kit is cheaply made of
acrylic or PVC that melts at 180-190 degrees F, then YES! If you
don't control the current it will melt around the terminals and
leak. Ours are designed to withstand even constant currents of
50 amps+ without damage. They don't need one to regulate current
for protection like cheaper models, but if you want more precise
control- they are great to use.
WHAT ABOUT FREEZING TEMPERATURE?
YES! You should DEFINITELY use a PWM for your
HHO kit if you live in frigid climates or areas of extreme freezing
area. By increasing the electrolyte concentration and controlling
current with a good PWM, you can prevent freezing to - 40 degrees
Fahrenheit or Celcius! We show you how in our installation kit
