SYDNEY, AUSTRALIA and UPLAND, CA--(Marketwire - Jun 14, 2012) - Sustainable Environmental Technologies' ([ SET Corp ]) (OTCQB: [ SETS ]) (PINKSHEETS: [ SETS ]) worldwide distributor for its [ MultiGen ] product, World Environmental Solutions (WES), has received a purchase order to supply a MultiGen tri-generation system for an Australian Government Education Institution in the Riverina district of New South Wales. The natural gas-powered system will produce water from the air, heat, and reverse cycle air conditioning and electricity for the campus library and training rooms.

SET's MultiGen product is a unique solution that combines a number of highly reliable, efficient, low emissions, commercially proven technologies with its proprietary water-making technology. The MultiGen65g 90kWr system will provide a cooling capacity of 90kWr (26RT) to replace the facility's highly inefficient, obsolete air conditioning equipment. The water made from the air, approximately 450,000 litres per year (118,877 US gallons), will be used to irrigate nearby landscape. The natural gas-fired micro turbine component will generate 65kW of electricity per hour (569,000 kW per year), some of which will be used to power the MultiGen electric chiller while the micro turbine's waste exhaust heat will be used to power two absorption chillers. The chillers also can be fired by natural gas.

Excess electricity generated by the MultiGen system will be used at the site for other purposes, reducing the facility's grid requirement. The system can also operate as a back-up power supply in the event of an electricity grid failure. The MultiGen system will save an estimated 300 tons of CO₂ per year. The existing building management system will monitor the system's performance and gas consumed, as well as the electricity and water produced. Return on investment is expected within five years.

"The WES team spent countless hours on projections and quotations that were the catalyst for this first sale in Australia and prompted its use as an educational example for energy efficiency," said Mr. Bob Glaser, CEO, SET Corp. "We are confident that the success of this first unit will prompt many new orders. We thank and commend the WES team for their continued perseverance in achieving this milestone. We believe MultiGen will be embraced enthusiastically in Australia."

Grid-supplied electricity charges in Australia have increased by more than 40% in the last three years and are expected to increase a further 60% over the next two years due to the cost of new grid infrastructure and the July 2012 introduction of Australia's carbon tax. Many organisations are actively seeking solutions like SET's natural gas-powered MultiGen because gas prices increased by only 3.5% last year and are expected to hold steady, with predicted annual increases of 3.0 to 3.5%.

The Government's buying decision was influenced by MultiGen's ability to:

• Increase energy efficiency as a result of many functions from a single fuel source,
• Reduce reliance on the electricity grid,
• Buffer ever increasing grid supplied electricity price rises,
• Create savings resulting from peak shaving (i.e.: reduction in capacity, market and network charges),
• Act as an educational aid,
• Reduce greenhouse gas emissions and,
• Make water from air.

"During the last six months, we have worked with our technical partners and the facility to customize a MultiGen solution that meets the project requirements," WES CEO Mr. Wallie Ivision said. "Plans are already well advanced for the addition of a second MultiGen system at the facility, while a third is to be installed at another campus. We expect to receive more orders within the next three months."

This project is set to act as a prime example of energy efficient technology and also function as an educational aid. It is to be used as part of the HVAC engineering curriculum within the NSW Government's education program. WES will be working with educators to develop a MultiGen learning module to be integrated into the courses offered to students at the campuses where MultiGen systems will be installed.

MultiGen is a unique integrated and flexible solution that includes water-maker air handling units, air-cooled electric and absorption chillers, natural gas-powered micro turbine, heat exchanger, together with a gas compressor, chiller pumps, waste heat exhaust ducting and computer controls. MultiGen can be scaled to produce thousands of litres of water from the air per hour, megawatts of electricity and enough cooling and heating capacity for a large shopping centre or manufacturing facility.
