NEW PRODUCTS - INTEGRATED COMPUTERISED SOLUTIONS: ADAPTING YOUR VEHICLE TO MAKE HHO WORK.
There are now three basis product solutions/kits available from the site, in addition to being able to order cells only either assembled or preassembled. Please see the description for each product below, to find out which will suit your needs, before ordering. We have a range of products packaged with and without electronics suitable for different engine sizes from cars to trucks.
We have now introduced a comprehensive electronic package, which incorporates the cell(s) and DEFIEs (Dual 02 sensor and MAP sensor). The signals from the 02 sensors and MAP sensors are adjusted by our DEFIE to bring these values back into the correct range. The units are suitable for the latest ECU controlled fuel injection systems - from OBDII onwards. Our DEFIE will allow the engine to take full advantage of the higher octane, faster burning fuel mixture afforded by the induction of HHO.

HHO PRODUCTS:
Standard HHO Kit
FULL KIT SINGLE CELL - Euro 285

This hydrogen fuel cell kit includes all that you need to convert your vehicle to a hydrogen hybrid, converting water to hho gas as fuel additive to diesel or petrol engines. It does not come with electronics device and is therefore suitable for older pre OBDII computersied engine systems. In addition to the single assembled fuel economy cell (see below), the box of components includes: a 30amp relay, reservoir, safety valve*, electrical wiring, nylon re-enforced plastic pipe, electrical connectors, fuse holder and ties.
Included in the box is an instruction sheet, which will guide you through the process.
If you are not of a mechanical bent, a local mechanic will be able to install the unit in about an hour.
Our Hydrogen Dry Cell is assembled from all top of the line materials
The plates are 3.5" x 3.5" 18 gauge 316L stainless steel
The O Rings are 3/32" compressed to 1/16"
The O Rings are EPDM rubber heat resistant to 260 degrees
The Acrylic is 4"x4"x1/2 OR 7"x7"x1/2 thick rated at 300 degrees
The 2 hose barbs are 1/4"
The attachment bracket angles are aluminium
2 1/4-20 wing nuts for easy connection to the power source.
Standard HHO Kit Including Integrated Computer Solutions
HHO KIT PLUS DUAL SENSOR DEFIE - Euro 575
A comprehensive electronic package, which incorporates the cell(s) and dual DEFIEs (Dual 02 sensor and MAP sensor). The signals from the 02 sensors and MAP sensors are adjusted by our DEFIE to bring these values back into the correct range. The units are suitable for the latest ECU controlled fuel injection systems - from OBDII onwards. Our DEFIE will allow the engine to take full advantage of the higher octane, faster burning fuel mixture afforded by the induction of HHO.
This dual sensor device manipulates the voltages relayed to the ECU via i) the oxygen sensors - by telling the ECU the fuel mixture is rich, it will tell the fuel injectors to inject less gasoline and use more hydroxy. And ii) the MAP/MAF sensor enhancer: this manipulates the voltages being sent to the ECU from the MAP or MAF sensor, effectively controlling the air/fuel ratio.
The electronics package we have developed over a three year period of time has the ability to allow the engine to have a normal cold start and warm up cycle. This is critical to avoid stalls and stumbling of the engine during warm up. All DEFIE units come with Ammeter and on/ off switch to be installed in the cab. The Ammeter is important as it will tell the operator that the hho unit is working and how much the current is drawing, which is a good indication of hho output.
FEATURES:
Works on all O2 sensors, narrow band, wide band, and ARF sensors. Simple to move, clearly labeled terminal jumpers to change unit to desired use.
Works on any Map/Maf sensor that operates on 5 volts.
Soft Start feature which is important to avoid stumbles and stalls when the engine is cold. The unit gradually increases the voltage offset you program from zero offset to full offset in 4 minutes. Can be turned off if you wish.
ECM reset feature can be turned off if you wish.
Push Button Adjustment for the finest adjustment available on any unit. 1.2mv per push.
Special Terminal to read offset voltage.
Green and Red LED lights to let you know what is set and that the unit is working.
All solid state microprocessor,built into the project box of your choice.
Pre-wired clearly labeled for quick, easy installation
HHO KIT PLUS SINGLE SENSOR DEFIE - Euro 525
As above but a single sensor device suitable for vehicles requiring adjustment to O2 sensor only.
HHO Fuel Economy Products - Cell Only
FUEL CELL (ONLY) ASSEMBLED Euro 155

This hydrogen fuel economy cell has been properly assembled and leak tested in our facility and is ready to be put to work giving greater economy and lower emissions for a long and reliable life.
Although the cell is compact it is very efficient and produces the most efficient amount of hydrogen with very low heat and this results in a long service life. Converts water to hho gas as fuel additive to diesel or petrol.
Our Hydrogen Dry Cell is assembled from all top of the line materials
The plates are 8.9cm x 8.9cm ( 3.5" x 3.5") 18 gauge 316L stainless steel
The O Rings are 2.44mm ( 3/32" ) compressed to 0.8mm (1/16")
The O Rings are EPDM rubber heat resistant to 127 deg (C) ( 260 degrees (F))
The Acrylic is 10cmx10cmx12.7mm) (4"x4"x1/2") thick rated at 300 degrees(F) 148 deg (C)
The 2 hose barbs are 6.35mm ( 1/4" )
The attachment bracket angles are aluminium
2 6.4mm (1/4-20) wing nuts for easy connection to the power source
FUEL CELL (ONLY) UNASSEMBLED Euro 125

SORRY THIS ITEM IS NO LONGER AVAILABLE
This is a collection of highest quality components for you to assemble and connect to your own reservoir. Converts water to hho gas as fuel additive to diesel or petrol. The materials used are the very best we can get and will give excellent service and economy when assembled following the simple instructions.
Made from high quality 316L stainless steel which has the most resistance to corrosion and is designed to work reliably in the harshest environments.
