NATURAL GAS CO-AND TRI-GENERATION - CHP SYSTEMS - TECHNICALLY SUPERIOR BY DESIGN

Natural Gas Cogeneration and Tri-Generation CHP Systems
     

 
2G® NA-TEC® Natural Gas Cogeneration & Tri-Generation Technology    High-End Performance & Unmatched Quality
 

Our advanced 2G® NA-TEC® energy generation technology “combined heat and power” (CHP), also known as co-and tri-generation solution, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. By installing a CHP system designed to meet the thermal and electrical base-loads of a facility, cogeneration can greatly increase the overall operational efficiency while decreasing energy costs. At the same time, CHP reduces the emission of greenhouse gases.


Our NA-TEC® cogeneration CHP technology is a seamless system integration for a variety of technologies, thermal applications into existing building infrastructures. Natural gas has one of the lowest CO2 emission values of fossil fuels. With its well developed supply system (network grid), this natural resource has enormous potential to increase efficiency in the energy sector. Highly profitable energy generation modules from 2G® provide customers independence and significant savings.

2G® NA-TEC® CHP systems are composed of advanced and optimized natural gas engines, components, and materials skillfully incorporated into one connection-ready cogeneration module to be more efficient, stronger and longer-lasting than ordinary and conventional CHP designs. Our systems are designed for unsurpassed operation economy. We created the next generation of energy efficient natural gas CHP modules

2G®’s thermodynamically optimized MAN® gas engines with 2G-Drive® technology are ideal for biogas (CHP) installations. The technology behind 2G® gas engines and their controls makes them highly reliable, offering superior efficiency with extended engine life. The added benefits of these 2G-Drive® MAN® gas engines over the conventional standard MAN®, or any other gas engine in a similar size range, include an increase of up to 25% higher electrical efficiency, and in average 35% lower maintenance cost.

   
 
 

NA-TEC® cogeneration CHP technology is an integrated energy system that can be modified depending upon the needs of the energy end user. Onsite electrical power generation provides many advantages, combined with waste-heat recovery for heating, cooling, steam, dehumidification, or other process applications. A compact CHP design with integrated control-and switchgear, thermal energy distribution system and advanced enclosure options.

We offer more value than our competition by focusing on advanced technology improvements “superior by design”, and “system efficiency”, rather than just packaging a standard gas engine. Our NA-TEC® cogeneration power plants deliver exceptional performance while ensuring the environmentally friendly generation of electricity and heat at a combined efficiency often exceeding 90%.

CHP is more efficient, less fuel is required to produce a given energy output than with separate heat and power. Higher efficiency translates into lower operating costs, reduced emissions of all pollutants, increased reliability and power quality, reduced grid congestion and avoided distribution losses.

Thanks to our advanced 2G® NA-TEC® co-and tri-generation technologies, our natural gas CHP plants are able to achieve an overall efficiency rate exceeding 90%. This provides building operators such as hospitals, hotels, universities, schools, shopping malls, office complexes, processing facilities, factories, and other industries with high energy efficiency, profitability, independence, and in some cases they can become energy suppliers themselves.

Irrespective of the application or configuration,… 2G®'s CHP cogeneration modules can be easily integrated into any type of building, industrial facility, or HVAC infrastructure.

Traditionally cogeneration plants in North America have been sized between 1 and 10MW because smaller engines could not provide the same high efficiencies. 2G®’s thermodynamically optimized MAN® gas engines with 2G-Drive® technology are ideal for combined heat and power (CHP) installations. Now customers can also effectively utilize CHP’s <500ekW for on-site power generation, heat production, cooling, and for commercial or industrial heat recovery applications in decentralized locations. 2G offers an extensive range of natural gas CHP units from as small as 27ekW up to 3000ekW (larger units are available upon request).

In late 2010 our factory reached a milestone of 1500 CHP cogeneration systems manufactured, supplied and installed. Thanks to an additional production plant opened in 2009 and a new factory extension completed in November 2010, the total number of installed CHP systems is expected to reach more than 1800 by the end of 2011.

When it comes to highly efficient  cogeneration our customers don’t take chances. Time after time the worlds leading CHP developers select 2G® to safeguard their investment and success. Why? Because there is no higher level of quality, efficiency, and durability available. We could offer you promising words,… but the numbers of installed units say it all.
