HHO Dry Cell Kits
Our HHO Dry Cell
and HHO Dry Cell Kits are assembled from all top of the line parts and materials designed for Max. production
Our complete HHO Dry Cell kit and HHO Dry Cells have been supplied to thousands of satisfied customers world wide.
Having been in the hydrogen on demand business for years now, we have seen a lot of hho parts and products come and go.
One question we receive frequently about our hho generator kits is - Why are your Dry Cells and complete install kits less than others ?
Sometimes by huge amounts.
It is really quite simple, We started out to help people save money when gas prices were outrageous in 2008 and that is still our main purpose. We don't make much per unit, but it is a blessing to us and those who are saving on fuel bills.
I can not answer why there are hydrogen generator "salesmen" selling hho kits for ridiculous prices. Most of the Hydrogen Generators out there put out the same volume of hho gas or maybe less than what our hho dry cell kit has proven to produce time and time again.
I can only truthfully tell you what our hho cells and kits will and will not do for you. I can also truthfully tell you YOU DON'T NEED HUGE AMOUNTS OF HHO.
With our hho dry cell install kit it is our purpose to provide a high quality Hydrogen on Demand System that is a complete solution for the average "DIY" hho generator installer. You don't need to be a professional mechanic to install these hho dry cell kits.
With our complete dry cell kit the customer does not have to figure out what hho parts he or she needs and how the whole system is supposed to go together.
We have designed our dry cell kits so that all of the key components and instruction needed for a successful Hydrogen on demand installation are provided.
This makes it easier for you to start getting the benefits of this exciting hho technology within hours of receiving your complete hho kit.
We also strive to give you the best possible customer service. You don't have to be a prior customer to get help or answers about hho systems from us.
Please contact us if there is a question you need answered, or if there is anything we can do to make it easier for you to install any type of
Hydrogen on Demand System.

Hydrogen on demand on Big Diesels
Coming Very Soon
Those of you that have been following our hho blogs and updates know that we have been working on a larger scale hho generator system for Long haul Diesel trucks. We will be introducing the most affordable and dependable Hydrogen on Demand system on the market for large diesel trucks. The main components of our Diesel Hydrogen on demand system will be similar to our very popular hho dry cells, our dry cell design has proven to be the most dependable and maintenance free hho generator available.
I would like to post a heart felt Thank You to the hho dry cell distributors that have helped to produce and perfect this system.
- Mark in Arizona - who is currently installing test models of our hydrogen on demand diesel system in Washington State on large fleets.
- Kevin in Nevada who has experimented with our 21 plate systems on vehicles as early as 2008 models, and proven gains from 20% to 40%. Kevin will be installing our diesel HHO Generators on independently owned and operated tractor tralors.
- Byron in the Netherlands - Byron has made it possible for costmers overseas to get their hho dry cell systems faster and has also arranged for professional installs. We are making arrangements for the new HHO diesel systems soon.
What is an HHO Dry Cell Kit
Don't let the term "DRY CELL" kit fool you, these hho generators create hho gas the same way other "water splitting" devices do. By using electrolysis to split water into hho gas, a more appropriate name would be "hho sealed generator".
The dry cell hho generator receives electrolyte from the bubbler tank reservoir by means of gravity feed. Once the electrolyte fluid enters the hho dry cell/generator, it forces the hydrogen and oxygen (hho gas) back up and into the bubbler tank reservoir located above the cell along with the water mixture where the hho gas rises and is then pulled into the engine's intake system via a hose located at the very top of the bubbler tank reservoir. The water then recirculates back to the hho generator (drycell).
All of this is accomplished WITHOUT the use of any pump as the bubbling action from the electrolysis alone creates the pressure needed. Unlike wetcell hho generators where the electrodes are submersed in electrolyte mixture and continually heat the fluid, hho dry cell generators separate the electrolyte container from the hho generator, this makes the system run cooler and more efficiently with less amperage draw on your charging system.
These hho generators are very compact and fit where others cannot. But don't let the size fool you. Due to the design of our hho dry cell compared to other designs we produce more hho gas with less amps than other hho generators 2 or three times larger.

After Installing Your Complete HHO Dry Cell Kit:
Start by checking all your connections. Make sure your amp meter and inline fuse have
been installed.
Now start your vehicle. While it's running, watch for bubbling action inside of your
Reservoir. You should be able to see the gas entering the Reservoir
tank. On the reservoir tanks you get with your complete hho dry cell kit from hho2u.com
you will notice the return line is higher up on the tank, the water level should be just above the
hho gas/water inlet.
Now it's time to check how many amps your dry cell is pulling. We recommend always installing an ampere meter
when installing any hho generator kit, whether you are installing our complete hho dry cell kit or another hho generator
an amp meter is needed to monitor the system.
All our hho dry cells are designed to run at 10-18 amps without overheating at all. Our 11 plate dry cell will
produce over 1 liter of HHO gas per minute at this amp rate and the 21 plate dry cell kit will produce 2 liters of HHO gas per minute
if you have everything hooked up according to the instructions. (that's all the hydrogen your vehicle will need to see an improvement in fuel mileage).
See th truth about Amp Draw -- Why You want to keep amp draw under
20 amps for your hho dry cell system.
Notes From A Professional Mechanic Who Installs HHO Dry Cell Kits :
If you have installed everything correctly on your hho dry cell kit, within a short time, you will notice that the engine
starts to sound dramatically different. It will sound smoother and quieter. Your RPM's may be unstable for a couple of minutes. This is normal. The HHO gas is starting to change the combustion cycle and cancels the pinging and the engine is now adjusting to the
changes. Your RPM's will normalize in a couple of minutes.
Congratulations! Your new HHO Dry Cell Kit is now producing Hydrogen Gas!
HHO2u's hydrogen generators are professional Hydrogen on Demand Systems, our hho dry cells are not made out of Home Depot parts or kitchen utensils like with many other hho generator designs. All our hho dry cells are built with 18 gauge 316L Laser cut stainless steel plate.
This is for the expert experimenter; not the novice. What you do with this is up to you.
However... Keep in mind if you install this in a vehicle you may still need something to fool the computer
- leaning out the fuel mixture for the HHO gas to take FULL effect.
Yes, we have installed and have reports of many complete hho dry cell systems that require no
computer lean outs, and these do work, we recommend that you run your new hho dry cell for a test run
and accurately measure the fuel consumption with and without your hho dry cell system performing.
HOW THIS HHO DRY CELL WORKS
This hydrogen generator ( hho dry cell ) design is a circulating system in which the water travels from the reservoir through the cell and then back into the reservoir. No water pumps are needed.
The key to this circulating system is the cell. This cell design acts like a pump creating a self siphoning system that carries the gas and water back into the reservoir. The reservoir stores the water that is circulated through the system as well as acts as a bubbler system separating the water from the hho gas and lastly helps cool operating temperatures.

IS BIGGER BETTER With HHO Dry Cells ?
Please do not take our word on what your about to read. Do your own hho gas research, you might end up buying something that your vehicle does not need. Just because something is bigger, does not mean it works better. We can only tell you what we have honestly experienced while experimenting with Hydrogen on demand systems and developing hho generators and hho dry cells. The newer vehicles only need a small amount of HHO Gas, (apx. 1/4 to 1/2 LPM per liter of motor) to mix with the fuel to get great results.
One Question you may have is life and maintenance of your HHO Dry Cell Kit.
The cells that we use personally have about 20K miles on them. The 316L stainless steel Plates we use should last about 50K miles if maintain properly.
The only part of the cell that needs replacement are the orings roughly every 5-10K miles this will vary depending on how hot the cell runs over time. This is the cheapest part of the cell, Oring replacement kits are approximately $2.40 for 12 orings.
The only maintenance needed is to check the water levels and make sure there are no leaks in the system.
It is very important to maintain a water level of at least 1qrt.
How often do I check the water level ?
The average reports we get back from customers that install our HHO dry cell kits is that they are using approximately 2 cups of electrolyte mix to travel around 700 miles. This will vary, so we recommend you check the water levels at 250 and then 500.
If you have done your research, as you very well should on this awesome Hydrogen on Demand technology, you will find hundreds of sites offering all kinds of HHO Dry Cells and HHO Dry Cell Kits. The HHO Dry Cell Kits on our site have been tried an tested by thousands of hydrogen on demand installers.
Finding the right Hydrogen on Demand System or HHO Dry Cell is the most important thing for all who want to use these devices to clean up our environment and save money while doing it.

Here is what you can expect from your HHO Dry Cell Kit
The Good reports keep coming in - most of the testimonials are on our testimonial page but I though I would share a few.
I just talked to a gentleman in Florida that installed the 21 plate hho dry cell kit on a 2006 Avalanche and was very excited that his hho generator was pumping out about 2 LPM at 18 amps and he went from 13 to over 16 miles per gallon of gasoline. ( Jan- 2010 )
Here Is fraction of the positive Emails that came in recently (Posted July - 2010) :
Good Evening Larry,
I finally got hold of a KOH supplier here in Holland. Because of 9-11 and all those terrorist stories its not easy to get even the simplest chemicals here. I am now in the process of testing the drycell and i am getting amazing results.
For example without using the Dry cell my car computer displays 224 km (to go with the remaining fuel) If I switch it on I am getting a reading of 293 km. That's a 30.8 % gain. We are now going to move on to our hho dry cell kit on the Diesel.
Larry;
Thought I would let you know how my install went. We put the 11 plate hho dry cell kit on a 2000 jeta. After a few fill ups we are getting 38 miles per gallon as before we got 30. This is Awesome, Thanks. from New York.
