Hangzhou Risheng Decontamination Equipment Co., Ltd.

Research and Development

Research and development are key sources of our growth.  Relying on technological innovation and advanced facilities, our senior engineers research new products and improve our production capacity.

Since our establishment, our company has increased investment in R&D year-on-year to maintain our position as a leader in the air drying field.

In 1994, our company was evaluated as "State Hi-Ttech Enterprise" jointly by the Zhejiang Provincial Committee of Science and Technology and the Hangzhou Committee of Science and Technology.

In 1998, our patented low-dew point combined dryer developed by Risheng starting in 1996 passed the Provincial Level New Product Appraisal.

We began marketing a new generation of refrigerated dryer models for compressed air in 2000, and introduced the Sunshine series refrigeration dryers with environmental-friendly refrigerant in 2002.
