We have experienced well-trained teams in management, marketing and post-sale service. €œKeep innovating€ is core belief of our company. In the past years, we keep developing new core technology and make a great progress in global marketing, and our products have been exported to most of developed countries such as U.S, EU, Australia, and Japan.After years of research and innovated by Science institutions, combine the theory of air heat pump with new technologies and take full advantages of regenerative energy such as air and solar energy. We have developed new series of products like Air energy and heat pump water heater, central air conditioning heat pump water heater. We have made a miracle in big, middle, and small hot water and air conditioning supplying systems. The series of products with many advantages: energy-saving (only costs 20% as much as the ordinary water heater system), environment-protecting, safety, high thermal efficiency, stable and long life, low failure running rate etc. We will lead the new trends of cool-hot water supplying, and the air conditioning supplying system in the world. All the products passed the ISO9001:2000 certification in Hong Kong, Guangdong and other main manufacture bases, also successfully passed other quality & safety standards such as CCC, UL, CE and so on. All the products checked by the quality monitoring and testing center of Guangdong Province, and were awarded firstly for €œcertified product€. The air energy and heat pump water heater and central air conditioning water heater system are wildly in factories, schools, hospitals, hotels, restaurants, bathing center and so on.
