Environmental Tectonics Corporation Announces Major 100% EtO Sterilizer Equipment Contract
May 21, 2003
SOUTHAMPTON, Pa., May 21 /PRNewswire-FirstCall/ -- Environmental Tectonics Corporation (Amex: ETC) is proud to announce that it has been awarded a contract to deliver another 12-pallet 100% Industrial Ethylene Oxide sterilization chamber valued at $575,000 to a major contract sterilization company. This is the sixth unit purchased as part of this customer's continued growth. Because of the exemplary operational track record of the five chambers already in service with this customer, this new contract calls for ETC to design and deliver the new chamber to exactly the same performance specifications as previously supplied.

This sterilizer will feature ETC's unique Air Jacket Heating (AJH) system. This approach not only avoids the costly maintenance and repairs commonly associated with traditional water jacketed vessels, it maintains superior temperature distribution throughout the chamber, thus giving better overall performance and substantial energy savings.

ETC was selected for three primary reasons, its extensive experience in designing, manufacturing and installing large industrial 100% EtO Sterilization Systems, the track record of the ETC 100% EtO equipment already in service with this organization for the last 5 years, and ETC's competitive pricing.

Michael W. Allen, V. P. of ETC's Biomedical Systems and Sterilizer Group, commented, "Our ability and willingness to work with clients in order to develop the best possible solution to their problems is only one of the things that sets ETC apart from our competitors. This team approach enables our clients to tap into the expertise it has taken us many years to develop and get the equipment they need to do the job and maximize their return on investment. I believe this is why we are able to develop long-term relationships with our clients based on mutual trust, the quality of our products and ability to provide the very latest in sterilization systems controls technology."

ETC provides consultancy services to assist clients with facility design; specialized construction and retrofit control system upgrade requirements. This service enables companies wishing to develop or expand an EtO sterilization capability to achieve the best possible return on their investment by optimizing equipment selection and product throughput while maximizing facility safety.

ETC 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.
