Company's History

RISHENG set up.
 
1992
In Feb. 1994, Risheng commenced to produce the first refrigerated compressed air dryer.
 
1994
Our "refrigerated compressed air dryer" and the "Domnick hunter" flange compressed air filter were used in the largest steel company in China, which named "Baosteel Group Corporation."
 
May 1995
Risheng's 2000m2 of a plant was completed and put into use.
 
May 1997
"Risheng" built the test base for the full load test of the compressed air dryer which capacity is bigger than 20m3/min.
 
September 1998
Risheng finished the development of huge refrigerated compressed air dryer, and put it into use in Shanghai  " Baosteel Group Corporation".
 
December 1999
Risheng finished the development of the 3rd generation refrigerated, adsorption and combined compressed air dryer.
 
December 2000
Risheng successfully researched and developed a range of green refrigerated compressed air dryer with R404a environmental protection refrigerant. In the next four years, we continuously perfecting the green products (R134a,R404a,R407C)
 
April 2001
At the invitation of "domnick hunter", general manager Mr Zhang and so on 3 person of "Risheng" went to UK "domnick hunter" for training again.
 
October 2002
Risheng successfully developed energy-saving "low-loss external heating blast air (steam) regenerative adsorption dryer" (regeneration air consumption <2%, capacity of 150m3/min), and put it into use in Shanghai "South Korea's Samsung".
 
July 2003
Risheng successfully developed a new product of "zero air loss of heated blower regenerative adsorption air dryer" with energy saving efficiently, and put it into use in Tianjin "Korea Samsung".
 
September 2005
