It is the obligation of RISHENG and our return to RISHENG that provide you the effective, reliable, perfect and satisfactory compressed air purification.

We are always trying our best to adhere to the idea” innovation speeds development”, propose the way to solve the problem of compressed air drying purification.

In 1996, RISHENG manufactured the first national patent new equipment-----Combined Compressed Air Dryer through the positive cooperation with some design institutes in Dec. 1998, which passed the provincial evaluation and is imitated by many competitors since it came out because of its high energy-saving.

In 2001, we succeeded in empoldering “R404a environmental Refrigeration Compressed Air Dryer”, and perfecting series of environmental products in the following 4 years. (R134a /R404a/ R407C)

In 2002, we succeeded in empoldering the biggest External Heat Regenerative Dryer in the Asia, it is characterized as: single flow capacity is 620m3/min, using technical method to regulate the pressure and temperature flexibly, and it is tested by battalion successfully.

In 2003, we succeeded in empoldering the energy-saving model “low air loss Blower purge (vapor) Regenerative Dryers” (purge air loss<2%)

In 2005, we succeeded in empoldering a new energy-saving product “no air loss and Blower Purge Regenerative Dryers”

In 2005, we succeeded in empoldering the biggest Refrigeration Compressed Air Dryers, which Single flow capacity is 620m3/min

In 2006, In order to comply with environmental protection and throw ourselves into response for the slogan of “The construction economize type society”, issued by China government, RISHENG firstly produced two series of new products “environmental refrigerant system” Refrigeration Compressed Air Dryers and high energy-saving  “no air loss and Blower Purge Regenerative Dryers” in China.

In 2007, we successfully passed the procedure of “factory site audit” and “sealed products test”, which was organized by “license checking department of compressed air dryer”, and firstly passed the test of “production license” and formally gained it which was awarded by national license office, the No. of the production license is XK06-010-00074.

We have been always pursuing on highest quality and the spirit of “serve for the community on the basis of faith keeping” since the establishment in 1993. So the Risheng attaches much importance to the product quality, contract execution and after-sales service, hence wins customer’s trust and takes the leadership in production and sales volume in compressed air purification sector in China. Risheng’s products are now widely used by many famous large and medium companies in china.
