STWA AOT Midstream Gains ASME Certification

AOT(TM) Midstream Crude Oil Viscosity Reduction Product Clears Important Commercial Equipment Certification Milestone

SANTA BARBARA, CA -- (Marketwired) -- 04/18/13 -- 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 achieved ASME (American Society of Mechanical Engineers) Section VIII, Division 1 certification.

The ASME Boiler and Pressure Vessel Code (BPVC) analyzes and tests the equipment to provide grounds for safe operating parameters, and a margin for useful service life for the product. The international code certification process analyzes the structural and manufacturing integrity of commercial equipment and is a part of the clearance process for installation of new equipment to commercial installations. Successful completion of this step is required prior to clearance from regulatory agencies to approve installation of the new equipment to customer installation sites.

"The ASME certification process is an important milestone for our new commercial equipment," stated Mr. Cecil Bond Kyte, Chairman and CEO of STWA, Inc. "Our team and our supply chain have been working diligently to make the AOT™ Midstream into the latest 'Must Have' equipment for this important industry. Achieving successful ASME certification for the equipment is a key step towards achieving this goal."

ASME helps the global engineering community develop solutions to real world challenges. Founded in 1880 as the American Society of Mechanical Engineers, ASME is a not-for-profit professional organization that enables collaboration, knowledge sharing and skill development across all engineering disciplines, while promoting the vital role of the engineer in society. ASME codes and standards, publications, conferences, continuing education and professional development programs provide a foundation for advancing technical knowledge and a safer world.

About ASME BPVC Section VIII Division 1
This Division of Section VIII provides requirements applicable to the design, fabrication, inspection, testing, and certification of pressure vessels operating at either internal or external pressures exceeding 15 psig. Such pressure vessels may be fired or unfired. Specific requirements apply to several classes of material used in pressure vessel construction, and also to fabrication methods such as welding, forging and brazing. It contains mandatory and nonmandatory appendices detailing supplementary design criteria, nondestructive examination and inspection acceptance standards.

About AOT™ Midstream
The AOT™ Midstream enhanced oil transport system is a commercial crude oil pipeline flow assurance product designed to be installed at pipeline pump stations in the upstream, gathering and midstream sectors. AOT™ is a turn-key product that uses an ultra-low amperage electric bath to encourage particulate matter aggregation of the paraffin and/or asphalt content of the crude oil being transported to reduce the viscosity of the crude oil quickly and easily. The reduction of viscosity holds key benefits to the energy production and transportation industry. The product holds advantages over currently adopted flow assurance technologies in use around the world today. AOT™ has been independently verified and tested by numerous third party entities such as the United States Department of Energy mentioned above, for the efficacy of AOT™ for the reduction of crude oil viscosity. Test reports and related links are available on the Company's website.
