    Strong points of our products

    Hydrogen fuel cell hho gas generator dimensions - the small size of our Hydrogen fuel cell hho gas generators allows easy installation in all cars. The dry cell can also be installed horizontally or vertically allowing greater flexibility for the installation.

    Hydrogen fuel cell hho gas production - despite its performance, the cell size is relatively small in proportion to the quantity of gas produced ensuring optimum operation over time. The easy reconfiguration of the plates (plus, minus, neutral), by a system of terminals, allows a better optimization according to your needs.

    Stainless steel plates – our plates are manufactured in 316 L stainless steel, laser cut, with a special chemical and physical treatment developed by our team to extend the operational life of the Hydrogen fuel cell hho gas generator. You will not see brown deposits in our dry cells. A certificate from the manufacturer guarantee the quality and durability of stainless steel that we use.

    Flanges - the new nylon flanges have been developed solely for our Hydrogen fuel cell hho gas generators. Good physical resistance and, above all, thermal resistance (melting point 190-350°C) makes nylon the best selection material for these products. As the Hydrogen fuel cell hho gas generator will be installed in the engine compartment, where the temperatures inside in summer can be very high, the thermal resistance of the materials used is very important.

    Gaskets and Seals - we use special elastomers made from EPDM rubber (temperature limits of use: -40 to 200 ° C), with a square section and large contact surface. Optimal distribution of pressure throughout the sealing surfaces.

    Bubbler tank - bubblers serve two purposes - cleaning the Hydrogen fuel cell hho gas and acting as a safety barrier. When Hydrogen fuel cell hho gas is produced from a dry cell, some water vapour is produced as well. This water vapour can carry tiny particles of electrolyte which can cause damaging corrosion. As the Hydrogen fuel cell hho gas bubbles rise up the column of water inside the bubbler they are "filtered" of any electrolyte particles that were attached to the water vapour. The result is much cleaner Hydrogen fuel cell hho gas. In the event of a flashback, the bubbler acts as a safety barrier. If a flame reaches the bubbler and ignites the HHO that has accumulated at the top, the water column will prevent the Hydrogen fuel cell hho gas from going on to the dry cell because the flame cannot skip from bubble to bubble.

    Summary of the strong points of our products:

  • Construction materials with very high quality ensuring a long product life;
  • Easy plate reconfiguration (positive, negative and neutral) by a system of terminals, for optimizing the performance of your system;
  • Absence of brown deposits in the dry cell and electrolyte circuit;
  • Stable operating temperature of the Hydrogen fuel cell hho gas generator without risk of overheating
  • Isolation of the cell to withstand extreme cold in winter conditions in order to continue to be effective even in the more severe conditions;
  • High system security based on protection bubbler tank.

The National Car Test

(Irish: An tSeirbhís Náisiúnta Tástála Carranna; abbreviated NCT) is a roadworthiness test, which all cars in Ireland must undergo.

What to Do if You Have Failed on Emissions?

If you failed the NCT Emissions test you should buy a 1 HHO KIT Hydrogen generator for fix CO emissions. Drive your car for 1 to 2 days 100 km and then take a re-test. Most Motorists should pass on the 2nd attempt. Watch video and pictures of NCT Exhaust emission PASS.



The vehicle has failed an emissions test or the exhaust emissions are too high as measured by an emissions analyser.

USUAL CAUSE smog test

There are numerous components that if not working properly, can cause high emissions or an emissions test failure. You should read each of the components description and operation in the emission control system section of the manufacturer’s manual covering your vehicle in order to gain a working knowledge of each system. These systems are designed to reduce the emissions (as set by NCT emissions standards). If any of these emissions components fail, emissions can increase. Along with these systems, other components such as spark plugs, plug wires, and filters can also increase emissions if defective. Emissions or smog is a generic term used to describe certain harmful gases in the exhaust. Hydrocarbons (HC), Carbon Monoxide (CO) and Oxides of Nitrogen (NOX) are usually measured in an emissions test. The NCT certain limits on each of these harmful gases emitted. Carbon Dioxide (CO) is also measured, but is not considered a harmful gas. When the measured gases from the vehicle exceed the NCT limits, the vehicle fails the emissions test.


Diagnosis of high emissions can be an involved process that usually requires special tools and measuring equipment. However, armed with a test report indicating what gases are high can help you determine what systems may not be functional. If the vehicle has failed as a result of high CO and HC, the CO failure should be diagnosed first. If the “Service Engine Soon” or “Check Engine” light is on it should be diagnosed prior to any emissions diagnosis. CO Failure is the result of an excessively rich air fuel mixture. The following is a list of the most common causes:

HC Failure is the result of incomplete combustion. Any item that causes incomplete combustion can result in high HC. The most common causes are:

NOX Failure is the result of combustion temperatures that are too high. The most common causes are:


If the engine is due for a tune up it is wise to perform preventative maintenance prior to spending too much time diagnosing the emissions problem. Proper vehicle maintenance can go a long way in keeping a vehicle’s emissions within specifications. A complete tune-up should consist of: spark plugs, ditributor cap and rotor (if equipped), spark plug wires, air filter, fuel filter, and oil change. Although performing this service is no gaurantee of a passed emissions test, it certainly increases the likelyhood of success. If the vehicle has over 60,000 miles on it and has failed for the reason of high CO, installation of a HHO KIT Hydrogen Generator might be a prudent investment especially if the vehicle is only equipped with one sensor.
