Oxy-hydrogen technologies

NEC Ltd. Is focused on developing of Electrolysis Generators and the OXY-HYDROGEN gas integration in to ecological friendly systems for industrial and domestic use!

Reduce energy consumption & bring real value to our partners.
New energy Corporation Ltd. is an engineering company, established to develop and implement energy-saving and environmentally friendly technologies.

Since 2014 NEC Ltd. is focused in the OXY-HYDROGEN generator design and constructions. During the years the company is working on technology improvements and cost effective gas production. The NEC Ltd. generators are known with their reliability and packed size.

Our philosophy is to implement OXY-HYDROGEN gas to and products and/or end processes.

Based on the idea for cost effective OXY-HYDROGEN gas production, we developed our machines, using self-invented devices and technologies:

  • Self-developed electrolytic cells (stackable)
  • Device and Technology for 100% gas extraction
  • Low electrolyte saturation – 3-5% only
  • Device and Technology for gas drying
  • Industrial Automation controlled process
  • Automation controlled heating and cooling technology
  • Remote access – real time control and analysis of the machine and process

The gas generators, produced by our company are unique in their efficiency – performance related to input of energy (electricity) and there is still no such equivalent known, even worldwide.



Vitrification is a process of hazardous waste material integrations in liquid glass structure under high temperature (above 1400 degrees Celsius). Hazardous waste can be, but not only:

  • Fly ashes from Municipal Waste Incineration/ Incineration process
  • Bottom ashes from Municipal Waste Incineration/ Incineration process or other residual of burning process
  • Asbestos

OXY-HYDROGEN gas is the cost-effective heating carrier allowing the process to achieve the needed temperature above 1400 degrees in a short time. NEC Ltd conducted in partnership with BalBok Engineering Co. in laboratory environment vitrification of hazardous waste in form of bottom ashes and fly ashes from incinerating installation. The results were excellent and according BalBok Engineering Co laboratory the end product is in stable condition and is not any more hazard. That means it can be dispose with no more impact on the environment.



Internal combustion engines. OXY-HYDROGEN gas mixed with the primary fuel. As result: increasing of the engine efficiency, respectively lowering the basic fuel consumption up to 30% and reducing harmful emissions up to 70%. Actually, this technology is economically applicable to large engines – trucks, buses, some marine and locomotives engines, industrial machinery.

  • Cleaning of internal combustion engines. The problem with the pollution inside the internal combustion engines (deposits, oxides) is very typical in trucks, buses, cars. Treatment the engines with OXY-HYDROGEN gas, removes deposits and oxides, improves engine performance, reduces fuel consumption and harmful emissions. The treatment increasing engine life, avoid expensive chemical cleanings, and generate savings from cost reductions.
  • Integration of OXY-HYDROGEN systems in existing (or suspended from work due to pollution problems) heat and power plants working with oil or low-caloric fuels.
  • Improving the efficiency along with emissions enter the permitted norms of heat and power plants working with low-calorie fuels.
  • Production of standalone systems for full burning in eligible environmental standards of low caloric or waste fuels – oil, coal, waste oils, biofuels


A technology that allows to use Oxy-Hydrogen gas mixture instead of standard gases as Propane and Acetylene used in gas steel cutting processes.

Using Oxy-Hydrogen gas mixture as part of the cutting process gives following advantages:

  • Ecologically friendly technology: No carbon oxides and other harmful gases are generated during the process. Only water vapour is produced during the cutting process
  • Less total amount of Oxygen used in the process: lower amount in the cutting process and lower pressure than usual .The heating Oxygen is not used in the process.
  • Faster cutting speed: the percent vary from 25 to 50%.
  • No structure changes and no thermal deformations of the material due to the “point” heating during the cutting process.
  • Up to 70% cost savings can be achieved using the technology
    Faster cutting speed : the percent vary from up 25%, but is impressive in thicker materials.
    “point” heating of the material gives no structure changes and no thermal deformations. Besides purely technical, environmental and financial benefits, it is very important to note, that the OXY-HYDROGEN gas used, is produced and consumed locally and only when needed. This lower the costs for transport and storage of oxygen gas, and eliminates many regulations for handling oxygen gas.


Our company is developing new technology innovation, which can solve most of the problems, related to the harmful exhaust gasses, generated during the incineration processes. Integrating our unique device, we implement new kind of burning technology in the combustion processes in the primary and secondary combustion chamber of the incinerator. This solve most of the problems, related to the harmful exhaust gasses: elimination of dioxins and flue gasses, final filtration and elimination of the rest, harmful exhaust gases. Our technology is suitable for any type of incinerator, creating, after implementation, a 100% clean device.



The process of enriching the water with Oxy-Hydrogen gas in form of nano-bubbles gives benefits in many processes in Agriculture, Aquaculture, Aquaponics, Animal farms, Soil regeneration etc.

Using Oxy-hydrogen gas enriched water in Agriculture gives benefits, like improvements in resistance to diseases, soil life improvements, resistance to salinity and production of stronger and healthier livestock.

   DPF/Catalytic converter regeneration system

In recent years there has been a tendency to increase the requirements of environmental standards for exhaust gases of internal combustion engines, especially for diesel ones.

The factory-fitted dust particulate filters and catalytic converters have their own life, which, in the dynamic time we live in, is running out too quickly. Poor fuels, improper engine  maintenance also help to further shorten the life of these components.

Unfortunately, the cost of replacing these components is quite high, as in old cars (over 5 years) it may be comparable to the cost of the vehicle itself.

This issue has not been the case since yesterday, and various technologies for cleaning dust particulate filters are available on the market.

Based on the above, NEC Ltd developed a technology with no analogue for cleaning of dust particulate filters and catalytic converters of diesel engines. Using the oxy-hydrogen gas properties of combustion, we created a gas mixture specifically for this purpose. The ignited gas mixture reacts with the deposits in a specific manner by destroying them without disturbing the ceramic structure of the treated part. The cleaned workpiece is processed at “point” in layers to prevent lateral heat transfer to the surrounding surface.

No harmful gases are emitted during the process, making it environmentally friendly and harmless to the operators of the procedure.

chevronbefore and after

  • Environmentally friendly. No chemical compounds are used.

  • The technology consumes 6% of the electricity needed by other similar technologies

  • 75% less time needed for one single recycling compared to other DPF cleaning methods

  • 98% factory's DPF's parameters are reached

  • Better result compared to other known technologies on the market
