Environmental Tectonics Corporation's BioMedical Division Announces Multiple
Hyperbaric Chamber Sales

SOUTHAMPTON, Pa., Oct. 29 /PRNewswire-FirstCall/ -- Environmental Tectonics
Corporation's (OTC Bulletin Board: ETCC) ("ETC" or the "Company") BioMedical
Division today announced a record month for sales of their Baramed monoplace
chambers. Dave Mitchell, Vice President of ETC Controls Group, said, "A total
of 15 chambers have been sold within the last 30 day period. While our
industry is not immune to the current economic conditions, this record
performance reflects the technological superiority of our chamber and the
versatility of our O.S.C.A.R.(TM) (Operating System for Control And
Recordkeeping) system."

ETC is the industry's leader in computerized monoplace hyperbaric oxygen
chambers. The technology and expertise that is incorporated in ETC chambers
originates from our long standing diverse corporate background in software,
hardware and electrical design.

Like all monoplace hyperbaric chambers designed and manufactured by ETC
BioMedical, the unit contains O.S.C.A.R.(TM), ETC's integrated computerized
system which offers a comprehensive Electronic Medical Record (EMR) of the
treatment each patient receives.

Our automated operating system also includes programmable treatment protocols
and a patient friendly pressurization alternative (Smooth Ride(TM)), which
minimizes complications due to middle ear and sinus barotraumas without
increasing compression time. As an added safety feature, ETC's chambers
feature a full manual override system to avoid premature termination of
treatment protocol as a result of extended power outages.

ETC was incorporated in 1969 in Pennsylvania and this year we have celebrated
our 40th anniversary. Our core technologies include the design, manufacture
and sale of Training Services (TSG) which includes (1) software driven
products and services used to create and monitor the physiological effects of
flight; (2) high performance jet tactical flight simulation, and; (3) driving
and disaster simulation systems, and Control Systems (CSG) which includes: (1)
steam and gas sterilization; (2) testing and simulation devices for the
automotive industry, and; (3) hyperbaric and hypobaric chambers. Product
categories included in TSG are Aircrew Training Systems (ATS) and flight
simulators, disaster management systems and entertainment applications. CSG
includes sterilizers, environmental control devices and hyperbaric chambers
along with parts and service support.
