27 September 2010 – Tri-Tech Holding Inc. (Nasdaq: TRIT), a premier Chinese company that provides leading turn-key solutions in China for water resources, water and wastewater treatment, industrial safety and pollution control markets, announced today that its affiliate, Beijing Satellite Science & Technology Co. (BSST), has won a RMB 7.8 million (approximately $1.15 million) Phase II bid from the China Petroleum & Chemical Corporation (Sinopec) for an automated monitoring and communication system in the Puguang gas field in Sichuan Province.

Phase II represents an expansion of the information gathering and monitoring Phase I project, which includes the 48-station system implemented by BSST in September 2010 at the Puguang field.

The new project includes engineering, procurement, installation and commissioning for 26 monitoring stations. The system connects the gas field SCADA control center with the gas wellheads and control valve stations, providing real time safe and reliable backbone and backup data transmission channel, to gather and safely transmit all the production data in real time.

BSST is applying the Siemens SCALANCE Industrial Ethernet switch and router used in Phase I. BSST expects to complete the project by December 2011.

Tri-Tech President Gavin Cheng said, “Following our successful completion of Phase I in 2008, we were pleased to be awarded this Phase II expansion project. This will be the first time we have used a redundant fiber optic ring and a wimax wireless link as a backbone and backup communication channel in a gas or oil field.”

Tri-Tech CEO Warren Zhao added, “Following the Sinopec award of the turnkey project for a 800M TETRA Network Communications System award announced last week, this industrial Ethernet based project is another important step in demonstrating Tri-Tech’s expanding capabilities and our ability to build a long-term relationship with large petroleum and petrochemical companies.”
