Environmental Tectonics Corporation Announces Joe Gibbs Racing Adds ETC's Conditioned Air Supply System to Enhance Engine Testing Capability

    SOUTHAMPTON, Pa., March 19 Environmental Tectonics
Corporation (Amex: ETC), today announced that Joe Gibbs Racing (JGR), the 2000
NASCAR Winston Cup Series Champion, is now utilizing ETC's Conditioned Air
Supply System (CAS(R)) for improved accuracy in their race car engine testing.
    JGR's dedication to winning includes a commitment to finding the most
advanced technology available to help improve the performance and durability
of their racing engines.  In their quest to attain superiority through the
newest advances in engine testing equipment, JGR has forged a close
partnership with ETC, the designers and manufacturers of the CAS.  ETC's
equipment will improve the accuracy and repeatability of JGR's engine testing,
helping them to improve their competitiveness in NASCAR Winston Cup Racing.
    The CAS provides psychometrically controlled air for improving the
accuracy and repeatability of engine performance testing.  Utilizing ETC's CAS
unit and its Engine Pressure Control (EPC(TM)) device eliminates the adverse
effects of variations in temperature, humidity and barometric pressure.  The
CAS is much more cost-effective than the traditional method of testing in a
climate-controlled chamber.  The CAS system also allows elimination of the
variable of ambient weather from engine testing, thereby permitting refinement
and improvement of engine performance under all types of conditions.
    JGR's Head Engine Builder, Mark Conquist -- "2000 Engine Builder of the
Year" -- states, "We are using the ETC CAS system to enhance our engine
testing capability.  In the ultra-competitive arena of Winston Cup Racing, we
need technical partners like ETC and their CAS to help us improve the accuracy
and repeatability of our engine testing."
    ETC's Testing and Simulation Systems Division has been designing and
manufacturing the most technologically advanced equipment available for
Automotive, HVAC, Aeronautical and various other industries for over thirty
years.  Visit their website at http://www.etcusa.com or contact Mr. Chuck East for
more information.
    ETC designs, 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.
