ENVIRONMENTAL TECTONICS CORPORATION - Press Release
Environmental Tectonics Corporation Announces the Award of an Altitude Simulation Contract for China
July 23, 2002
SOUTHAMPTON, PA: July 23, 2002- Environmental Tectonics Corporation's (Amex: ETC - news) Environmental Division today announced that the company has been awarded a contract to supply an Altitude Simulation System for vehicle testing at high altitudes to First Automobile Works (FAW) in Changchun, China. The Altitude Simulation System will be integrated with the ETC Climatic Drive-in Chambers currently under construction at FAW.

ETC has been designing and manufacturing Testing and Simulations Systems for the Automotive and HVAC Industries for the last 32 years. The test systems designed for the automotive industry includes 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.

An Altitude Simulation System provides an additional capability of testing vehicle performance and emission at high altitudes under extreme environmental conditions. The ETC Altitude Simulation System can simulate up to 10,000 feet.

ETC's Altitude Simulation System is a uniquely designed system where high altitude conditions are simulated for the engine induction air and exhaust. A controlled pressure drop of engine intake air is generated by using a valve and vacuum pump system. Similarly, the reduced pressure conditions are created for the engine exhaust. The ETC Altitude Simulation System is much more cost efficient than providing an Altitude Simulation Chamber. This technology is also applicable to the NASCAR and FORMULA 1 racing teams.

New vehicle design and performance verification requires extensive testing. This performance verification is done under extreme environmental conditions. A climatic drive-in chamber provides such a facility and is equipped with a chassis dynamometer, temperature and humidity controls, solar and wind speed simulation, etc. A climatic drive-in chamber can create conditions from extremely cold to extremely hot and humid in just a few hours, thus allows testing 24 hours a day and eliminates the need to drive the vehicle to places with extreme weather for testing.

ETC's climatic drive-in chamber is a stainless steel chamber measuring 56 feet in length, 25 feet in width and is12 feet high. The chamber has a temperature range -50°F to 122°F with relative humidity of 20 to 95%. The chamber includes a 250 kW chassis dynamometer, wind and solar simulation capability and is equipped with the latest and most accurate sensors, controls, and data acquisition system and is fully automated. Adding an Altitude Simulation System enhances the capability of Climatic Drive-in Chambers.

The chamber creates very precise test conditions thus generating very accurate and repeatable results. The chamber will be used to evaluate air conditioning systems, engine performance, fuel economy, exhaust emissions, etc.

ETC (the "Company") also designs, develops, installs and maintains aircrew training systems, public entertainment systems, process simulation systems (sterilization and environmental), clinical hyperbaric systems, environmental testing and simulation systems, and related products for domestic and international customers.
