Our company is a famous enterprise specializing in energy construction contract management systems and building energy-saving constructions. Our company is committed to the overall design of energy systems and technology development, application and promotion of energy-saving products. With the international energy supply tensions, our company's strategy has been gradually shifted to focusing on the application of heat pump technology. Our company is a major unit of the World Ground Source Heat Pump Association (IGSHPA). We have participated in drafting the ASHRAE standards of heat pump technology. In recent years, our company has been focusing on the promotion and application of natural refrigerants.

We are engaged in the research, application and development of energy conservation and environmentally-friendly refrigeration, air conditioning, and heating products and technologies. We have developed water-source heat pumps, air-source heat pump hot water units, Wei-integration units, wind Lengleng (hot) water air-conditioning units, chillers, and other industrial products.

Our company has also independently researched and developed long spiral pipe casing efficient heat exchangers, reaching the domestically advanced level. Our titanium, nickel-brass, and stainless steel pipes and other special corrosion-resistant heat exchangers can be widely used in swimming pools, water, temperature and other special places.
