ETC Receives Contract for Combustion/Dilution Air System

Southampton, Pa, July 16, 2007: - Environmental Tectonics Corporation's (AMEX:ETC) ("ETC" or the "Company") Environmental Testing and Simulations Systems Division today announced receipt of a contract to supply a Combustion/Dilution Air Supply (CDAS) system, with pressure control feature, to a major domestic engine supplier in the Detroit area. The CDAS will be used to test automotive engine performance, as well as emissions.

ETC has been designing and manufacturing testing and simulations systems for the automotive and Heating, Ventilation and Air Conditioning Industries for nearly four decades. Test systems designed specifically for the automotive industry include environmentally controlled drive-in chambers, A/C Systems, test benches and calorimeters, component and full vehicle development wind tunnels, engine development systems and automotive emissions testing systems.

ETC's standard Conditioned Air Supply (CAS) System, a product of many years standing in the automotive industry, provides combustion air for testing engines and dilution air for exhaust emission measurements. The system delivers air at precisely controlled temperature, humidity, and pressure. It also includes HEPA filters to insure that the delivered air is free of pollutants. This system greatly eliminates the uncertainties arising from variations in air temperature, humidity and pressure.

Theresa Wagner, Environmental Systems Division Sales & Marketing Manager, stated, "As always, ETC is committed to providing our customers with high quality, well-proven, test equipment to assist them in achieving their goal of automotive excellence, with focus on fuel efficiency, low emissions and dynamic performance. We are proud that our customer has contracted with ETC to help fulfill this mission."
