Our Company

Altex Technologies Corporation leverages the unique knowledge and experience of its staff, and available special analysis and testing tools, to provide these solutions, at a lower cost, for industry and the public

Altex is a privately held corporation, organized in the State of California, and located in the heart of Silicon Valley, just south of San Francisco. The company was founded in 1985, to pursue the development of novel fuels processing, combustion, thermal management and power systems technologies, including fuel cells, gas turbines, biomass conversion, burners and heat exchanger components and systems. The early focus of the company was on the research and understanding of fuels and combustion processes. This work was accomplished in cooperation with academic and government research laboratory personnel at Sandia National Laboratories, Livermore. During the mid 90s, the company focused on the transition of fundamental knowledge to benefit power, energy and environmental products. This transition of knowledge to innovative products has been applied to all our development activities
Altex's facility has nearly 15,000 square feet of space, with approximately one half devoted to testing and test article preparation. Test instrumentation covers all of the equipment needed to characterize fuels and combustion system performance, including flow and temperature monitors, total sulfur analyzer, GC, and continuous gaseous emissions (CO, CO2, O2, NO, NOx and unburned hydrocarbons) monitors. Below on the left is a picture of our nearly 3MWt test boiler system that can support burner testing. Also, an ASHRAE 33 standard heat exchanger test facility is available for testing radiators and cooling coils. This unit is pictured to the right.
Altex has unique combustion and heat management and fuels processing skills based on proprietary technology, based on 30 years of fuels processing and combustion R&D. Altex has strong relationships with several manufacturing partners that support Altex from demonstration commercialization. By integrating strong R & D with product commercialization, solution development can proceed to market in a timely manner, and at low risk.
