We are a designer, manufacturer and seller of clean technology plate heat exchangers and related systems in the PRC. Our products are used by our customers in the industrial, residential and commercial markets in China to improve energy utilization and efficiencies and reduce pollution by reducing the need for coal fired boilers. We design, manufacture, sell and service plate heat exchangers (“PHEs”), PHE Units, which combine PHEs with various pumps, temperature sensors, valves and automated control systems, and heat meters for use in commercial and residential buildings. We also design, manufacture and sell spiral heat exchangers and tube heat exchangers. Our products and systems are an increasingly important element in providing a clean technology, mission-critical solution to energy consumption and air pollution problems in China and are commonly used in a wide variety of industrial processes where heat transfer is required. Common applications include energy conversion for heating, ventilation and air conditioning (“HVAC”) and industrial use in petroleum refining, petrochemicals, metallurgy, food and beverage and chemical processing. Our PHE Units are custom designed by our own in-house engineers and sold under our Taiyu brand name, while our PHEs are sold under both our Taiyu brand as well as the Sondex brand name. We are an authorized dealer of Sondex PHEs in China.

A PHE is a device that transfers energy from one fluid to another across a solid surface. PHEs consist of a set of plates made of stainless steel, titanium or nickel alloy that are sealed by gaskets and then bolted together in a large metal frame. Plates come in a variety of sizes and wave patterns, and have large heat transfer surfaces and high thermal conductivity. The quantity and size of the plates and size of the PHEs and PHE Units vary according to particular application requirements.

Among the primary advantages of plate heat exchangers as compared to traditional shell-and-tube heat exchangers are their efficiency, compact design and ease of customization. PHEs have larger heat transfer surface areas and therefore greater thermal conductivity. As a result, a PHE can transfer the same amount of heat as a traditional shell-and-tube heat exchanger despite its smaller size. In China, coal is the predominant source of heat energy, and coal burning is a significant contributor to carbon dioxide (“CO2”) emissions. According to International Energy Statistics provided by the Energy Information Administration, a subdivision of the United States Department of Energy, in 2007, the consumption of coal accounted for 27% of the total primary energy consumption in the world. China was the largest producer of CO2 emissions from the consumption of coal in 2009, accounting for 48.4% of the world total.

The PRC government’s 12th Five-Year Plan announced in 2011 targets up to a 17% reduction in energy consumption and CO2 emissions per unit of GDP from 2010 levels by 2015. Furthermore, the PRC Ministry of Environmental Protection has issued CO2 emissions quotas through 2015 to provincial governments, providing clear energy and emissions targets to help ensure energy policies are implemented with defined carbon goals. As the PRC government continues to require the use of machines that produce more efficient heat transfer and utilize waste heat energy, PHEs will be an increasingly important element in reducing overall coal consumption in China, which will translate into lower heating costs, lower CO2 emissions for users and less pollution to the environment. According to the PRC government, China has cut energy use per unit of GDP by 14.4% between 2006 and 2009 and it aims to cut CO2 output per unit of GDP by at least 40% by 2020 compared with 2005 levels.

We currently focus predominantly on the domestic Chinese market. All designs of our PHEs and PHE Units are done in-house by our engineers utilizing advanced software and our proprietary in-house CAD software. Through our acquisition of Siping Beifang Heat Exchanger Manufacture Co., Ltd. (“Siping Beifang”) in 2009, one of the major plate heat exchanger manufacturers in China, we can manufacture our own plates, tubes and gaskets and can design and manufacture PHEs and PHE Units using component plates sourced from our own vertically integrated supply chain or from our main supplier of component plates, Sondex. Our plates provide solutions for a market segment with strong demand for PHE products that are priced 10-15% lower than PHE products manufactured with Sondex plates.

In early 2006, we launched a third product line, heat meters, which utilize the same sales channels and allows us to provide heat consumption information to users. Heat meters precisely measure the volume of heat usage, which is an important revenue stream for utility companies. While home owners commonly use heat meters in Western countries, widespread incorporation of heat meters has only recently taken hold in China. In July 2003, in response to rising energy costs and increased sensitivity to environmental issues, the PRC government made the use of heat meters required nationally for new construction installed with central heating; the requirement was extended in April 2008 by the Energy Conservation Law, Article 38, to cover existing buildings being retrofitted. We believe there are significant opportunities for strong incremental growth as the PRC government continues to focus on ways to cost effectively monitor and conserve energy.

In 2011, we anticipate launching a new product line, heat pumps, in the domestic Chinese market. Heat pump systems provide heating, cooling and hot water for residential and commercial buildings and process heat for industrial applications using small amounts of electricity. Heat pumps are replacing conventional energy sources such as oil, gas and coal by using the solar energy stored in water, soil and air or recovering heat from wastewater or exhaust air. The various advantages of heat pumps in terms of energy efficiency, operating cost, CO2 emission reduction and their ability to provide heating and cooling in one machine has made them the leading energy source for new buildings in Germany and Austria, and has replaced conventional fossil fuel based technology in these countries to a large degree. We plan to begin designing, manufacturing and selling heat pumps for the rapidly growing heat pump market in China in 2011.

In 2010, we generated net sales of $125.4 million and net income of $22.7 million, representing year-over-year growth rates of 52% and 47%, respectively. We experienced similar growth rates from 2006 to 2010, during which period our total revenue increased from $8.2 million to $125.4 million (a compound annual growth rate (“CAGR”) of 98%), and our net income grew at a 129% CAGR from $0.8 million in 2006 to $22.7 million in 2010.

Our headquarters and principal manufacturing facilities are located in Shenyang, China, where we have a 210,137 square foot state-of-the-art production facility. We operate two other production and assembly facilities in China, and anticipate expanding our facilities and production capacity in Shenyang in 2011. As of December 30, 2010, we had 776 full time employees and 180 seasonal employees.

We serve the utility and industrial sectors throughout China. Participants in these industries are large users of PHEs, PHE Units and related accessories. We also serve the HVAC sector. Participants in this industry are large users of heat meters. We also provide after-sales services on our PHEs, PHE Units and heat meters to these industries. These services include maintenance, repair and supplying spare parts.

According to the “China Heat Exchanger Industry Report” (hereinafter referred to as the “Industry Report”) issued by Zero Power Intelligence Co., Ltd., an independent market research firm in China, the world heat exchanger market has grown significantly in the past several years. Global sales of heat exchangers grew from $29.7 billion in 2005 to $38.6 billion in 2008, or 30%, according to the Industry Report, and reached an estimated $50 billion in 2010, according to our research. The Industry Report expects the market to grow to $55.3 billion in 2012.

Environmental Conditions in China. According to the report entitled “The Cost of Pollution in China,” published in 2007 by the World Bank, the combined health and non-health cost of air and water pollution in China amounts to an estimated $100 billion a year. Moreover, the report found that air pollution, especially in large Chinese cities, is leading to higher incidences of lung diseases, cancer and respiratory problems. According to a report commissioned by the Energy Foundation published in 2008, these problems are directly attributable to the fact that 80% of China’s CO2 emissions come from burning coal.

Growing Demand for Heating Water. China currently provides households throughout 17 of its 34 northern provinces with heating water. As new cities grow along with the emerging middle class, so does the demand to expand this supply into new cities, industrial parks and other provinces. Heating water in China is generated by local power plants which pump emitted hot water from the power plant through a closed loop system to a water heating company and then through a network of pipes up to a distance of 50 kilometers. These systems of heating stations and sub-stations utilize numerous PHEs and PHE Units, which provide a dual purpose: a cooling system for the power plants and a heat source for residents and factories.

Heightened Environmental Awareness. Management expects the PRC government’s upcoming 12th Five-Year Plan to target cuts of CO2 output per unit of GDP by at least 40% from 2005 levels. Furthermore, the Plan is expected to have clear energy and CO2 emissions targets to help ensure energy policies are implemented with defined carbon goals. The implementation of PHEs and PHE Units in new construction facilities, and as replacements for legacy shell-and-tube heat exchangers, can help meet these goals because of their increased energy efficiency.

Urbanization. According to the CIA World Factbook, 47% of China’s population lived in urban settings in 2010. Additionally, according to the National Bureau of Statistics of China, 15 cities near and around our sales and service centers have a population of more than five million. Eight of these Chinese cities are among the world’s fastest growing, increasing at an annual rate of 2.3% or more. China’s urbanization has led to new infrastructure development and existing infrastructure improvements that require ongoing investment in heating solutions.

Provider of Key Elements Used to Improve Energy Efficiencies and Reduce Coal Pollution. We offer a full line of PHEs, PHE Units and heat meters, and will introduce heat pumps in 2011. The primary advantages of plate heat exchanger technology, compared to traditional shell-and-tube heat exchanger technology, are efficiency, compact design and ease of customization. PHEs have larger heat transfer surface areas and therefore also have greater thermal conductivity. As a result, PHEs can transfer the same amount of heat as a traditional shell-and-tube heat exchanger, but with the benefit of a smaller size unit.

Established Leader and Brand Name in the Growing China Heating Industry. We have established a leading brand name in the fragmented Chinese heating industry and seek to utilize this awareness to become the leading Chinese supplier of PHEs, PHE Units and related products in the rapidly growing Chinese market. We are one of the leading domestic producers of PHE Units under the Taiyu brand and management estimates that we have approximately a 12% share of the PHE Unit market in China based on our internal market research, which tracks PHE projects in China valued over $1.5 million. We believe the Taiyu brand name is recognized for its quality and efficiency, which we believe we can leverage to improve our reputation as a leading seller of high quality PHE Units in China.

Quality Engineering, Research and Development. We emphasize efficiency, durability and quality engineering in all of our products. All of our products utilize the latest technologies, and our designs are created using advanced software systems. We have eight registered patents in China for PHE products and heat meters. To maintain our competitive edge in the marketplace and keep pace with new technologies, we fund research and development on an on-going basis to find improved efficiencies in design, cost and energy capture. Research and development costs for 2010, 2009 and 2008, were $1.89 million, $1.36 million and $1.02 million, respectively. We plan to continue to invest in research and development to identify new industry applications for PHEs, improve and expand our product lines, including the introduction of heat pumps in 2011, develop multifunctional PHE Units and modify PHE designs to meet current market demand.

Strong Technical Support. The selection of PHEs and PHE Units requires technical knowledge regarding the operating temperature, pressure, corrosivity, viscosity and purity of the fluid as well as the pressure loss within the system. Our unique design software enables us to provide high quality and timely technical support to ensure our customers receive the right equipment for each project. We also provide a streamlined and error free installation process to minimize project complications.

Enterprise-Wide Design, Production and Control Systems for Efficient Pricing and Streamlined Manufacturing. Our technologically advanced CAD systems are integrated with our real-time enterprise resource planning and finance systems. This advanced, integrated platform allows our field salespeople to input orders, obtain draft models, access quotes and confirm delivery dates within minutes. The platform also enables inventory and production personnel to accurately schedule and reduce lead production times to five days for PHEs and ten days for PHE Units. We believe these lead times are some of the best in the industry and provide an unparalleled level of customer service.

First-Rate Customer Service and Reliable Product Delivery. We believe that our employees provide first-rate customer service, technical expertise and product knowledge to streamline the selection, design and installation processes. We provide after-sales service through our local service centers and deliver products on time to meet tight project deadlines. Our focus on delivering premium service separates us from our competitors and has been critical in helping us win a number of projects for various multinational companies and local governments.

Diversified End Markets and Customers. Our PHEs and PHE Units are broadly used across a variety of industrial end markets including the energy (i.e., conventional and nuclear power plants), HVAC, petroleum refining, petrochemicals, metallurgy, food and beverage and chemical processing end markets. We also benefit from a diverse customer mix, with no individual customer accounting for greater than 10% of sales in 2010, 2009 or 2008. This end market and customer diversification helps to insulate us from sales volatility that would occur if we concentrated in specific industries. The majority of our customers are utilities, engineering and construction companies and industrial companies.

Proven Ability to Identify and Acquire Strategic Targets. We have completed multiple strategic acquisitions since 2008, including Siping Beifang, SanDeKe Co., Ltd. (“SanDeKe”), Gustrower Warmepumpen GmbH (“GWP”) and Shenyang Bingchuan Refrigerating Machine Ltd. Co. (“Bingchuan”). Each acquisition has accelerated our strategic plan by: (i) adding manufacturing capacity; (ii) broadening our product offerings to include multiple heat exchange systems; (iii) facilitating access into new geographic regions throughout China; (iv) improving our cost structure; (v) enhancing our engineering capabilities; and (vi) helping us enter new and higher growth end markets. We have proven our ability to complete successful acquisitions and believe there are additional acquisition opportunities both in the domestic Chinese market and internationally that we may potentially pursue.

Experienced Management Team. Our senior management team has extensive business and industry experience. Jun Wang, our Chairman, President and Chief Executive Officer, was the founder of Taiyu in 2002. He was a sales manager for Honeywell International Inc. from 1996 to 1999 and a sales manager for Alfa Laval from 1994 to 1996. Mr. Wang obtained his master’s degree in Engineering from Tsinghua University in 1989. Zhijuan Guo, our Chief Financial Officer, has over 15 years of finance and accounting experience and has been with us since inception in 2002. Xudong Wang, our Vice President of Strategy and Development, served previously as the vice president of an international financial firm. Wen Sha, our Vice President of Marketing, has extensive sales experience and industry contacts. Prior to joining us as a regional sales manager in 2005, he served as the general manager of Nanjing Hui Dun Ltd. and as sales director of APV Accessen in Shanghai, a leading international PHE firm. Feng Chen, Ph.D., our Chief Technology Officer, joined us in 2008 as part of our SanDeKe acquisition. Prior to founding SanDeKe, he served in a leading engineering position in China with Alfa Laval.

Pursue High Growth Chinese End Markets. We are targeting our sales efforts on a number of high growth domestic Chinese end markets, such as the nuclear power, petrochemical and ship-building industries. We currently have a presence in these segments but we believe that there are significant opportunities to improve our market share by leveraging our premium product quality and high quality service. Our solutions are commonly used in many of these industries and customers continue to assess the cost savings and positive environmental attributes of PHEs.

Continue Organic Growth Initiatives. We believe that the current PHE market is fragmented and represents an excellent opportunity for us to gain additional market share from our competitors. We intend to continue to open new sales offices, hire additional sales personnel, expand into new distribution channels and improve the quality of our products. We also intend to continue to leverage our strong brand, quality customer service, engineering and reliable product delivery to gain incremental business with our existing clients. Finally, we believe that as we continue to grow, economies of scale and improved cost control measures will drive stronger profitability across all product lines.

Promote Heat Meters. In response to rising energy costs and an increased focus on energy efficiency, the Chinese government and local utility companies have made the use of heat meters compulsory in China. In July 2003, heat meters were required nationally by law for new buildings installed with central heating; the requirement was extended in April 2008 by the Energy Conservation Law, Article 38, to cover existing buildings being retrofitted. We are currently working with the General Administration of Quality Supervision and Quarantine, an administrative organ established under the PRC’s State Council, to establish a national heating standard in China. We also intend to leverage the Taiyu brand and our reputation in the PHE market to gain market share.

Introduce Heat Pumps. Heat pump systems are a rapidly growing market in China and the leading energy source for new buildings in Germany and Austria. Heat pumps have replaced conventional fossil fuel based technology to a large degree in these European countries for heating, cooling and hot water for residential and commercial buildings. We plan to begin designing, manufacturing and selling heat pumps in 2011 for the China domestic market.

Execute Strategic Acquisitions. We intend to continue to acquire select domestic or international targets that would enable us to enter new markets or gain entry into new industries. For example, the asset acquisition of Siping Beifang in 2009 provided us with an entrance into the petrochemical and high pressure chemical end markets, which were previously immaterial industries for us. We also acquired SanDeKe in 2008, which increased our PHE and PHE Unit production capacity. Due to the high pressure and heat tolerance demands of the petrochemical industry, we have also acquired valuable engineering expertise that may help us serve the nuclear energy industry in a meaningful way. In 2011, we completed the acquisitions of GWP and Bingchuan, which will extend our clean technology solutions into the rapidly growing heat pump markets in Europe and China. Management believes it has a strong track record of acquiring companies that fit our strategic goals of reducing pollution and saving energy, and of successfully integrating their operations so they are accretive to earnings and contribute to our rapid growth. We will continue to identify and review targets that are accretive to our earnings, easily integrated into our existing infrastructure and synergistic to our operations.

The selling shareholders identified in this prospectus may offer and sell up to 134,675 shares of our common stock that we have issued to them or that we may issue to them upon the exercise of certain warrants issued to them. The selling shareholders may sell all or a portion of their shares through public or private transactions at prevailing market prices or at privately negotiated prices.

The selling shareholders may sell all or a portion of the shares of our common stock beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of our common stock are sold through underwriters or broker-dealers, the selling shareholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions,

If the selling shareholders effect such transactions by selling shares of common stock to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling shareholders or commissions from purchasers of the shares of common stock for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the shares of common stock or otherwise, the selling shareholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the shares of common stock in the course of hedging in positions they assume. The selling shareholders may also sell shares of common stock short and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling shareholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

The selling shareholders may pledge or grant a security interest in some or all of the warrants or shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b) or other applicable provision of the Securities Act amending, if necessary, the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The selling shareholders also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

The selling shareholders and any broker-dealer participating in the distribution of the shares of common stock may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of the shares of common stock is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of shares of common stock being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling shareholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

The selling shareholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock by the selling shareholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock to engage in market-making activities with respect to the shares of common stock. All of the foregoing may affect the marketability of the shares of common stock and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock.

We have agreed to pay all expenses of the registration of the shares of common stock including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, that a selling shareholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling shareholders against liabilities, including some liabilities under the Securities Act, in accordance with our agreement to register the shares, or the selling shareholders will be entitled to contribution. We may be indemnified by the selling shareholders against civil liabilities, including liabilities under the Securities Act, that may arise from any written information furnished to us by the selling shareholder specifically for use in this prospectus, in accordance with the related registration rights agreements, or we may be entitled to contribution.
