E3 was founded by an entrepreneurial team led by Dr. Tang Ming. The company's initial focus was to solve the safety/energy conservation problems that have plagued scientific laboratories around the world for nearly half a century.

Tang Ming, Ph.D. in cosmochemistry from University of Chicago; worked for Ford Motor Company for 12 years at senior management positions in different functions in North America, South America, Asia and Europe; After returning to China in 2002, he has achieved consecutive successful start-ups in different high-tech fields, including KananjiMediTechCo., which was acquired by BettaPharma, with CM082, a national major new drug creation project.

Fume Hood and Air Damperin scientific laboratories are the core hardware  that determine the laboratory's safety/energy saving level. The Bernoulli LaminarAir Curtain Fume Hood, developed by the E3 Team over the years, successfully solved this problem with 0.00ppm containment and more than 80% energy saving. Their another product, SmartFlow Air Damper, surpassed the functions of the famous Venturi valve at a fraction of cost.  Both products were evaluated by domestic and international HAVC experts as disruptive innovations in HAVC field for decades.
