SANTA BARBARA, CA -- (Marketwired) -- 05/09/13 -- STWA, Inc. (OTCBB: ZERO) ("STWA" or the "Company"), a developer of applied efficiency technology solutions for oil and fuel delivery systems in the multi-billion dollar global energy market, announced today that the Company's AOT™ Midstream has completed the final manufacturing and certification steps for use in the United States of America.

The first AOT™ Midstream Crude Oil Viscosity Reduction Technology production unit was released from production May 8, 2013.

AOT™ Midstream serial number 000001, Model: 36-12-600#-1200/200-042013-S-000001 is one of STWA's long distance commercial pipeline products, designed for use at pipeline pump stations throughout North America.

The 20-ton, 33.3 foot long industrial efficiency device is a 36 inch inner diameter pressure vessel, with 12 inch series 600# inlet and outlet nozzles rated for 1,200psi of continuous duty operation. It is loaded with STWA's AOT™ proprietary equipment and mounted to its own frame assembly design, known as a "skid", which allows the end user to mount the device in either horizontal or vertical orientation.

The AOT™ Midstream serial number 000001 shown is being shipped with 12" 600# pipeline mounting hardware and components compatible for installation to commercial pipeline pump stations in North America.

"This first unit off of the assembly line marks a key milestone for our Company as it has been a major collaborative exercise between all parties involved, and we thank each for their respective contributions for the design, engineering, parts and assembly processes," stated Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "The team has been working closely with intellectual property partners, potential customers and supply chain members since last spring to design this first unit, and others in line behind it, to meet the rigorous demands of high capacity throughput on commercial pipelines around the world. Thank you all for your support."
