Accurate selection of refrigeration compressed air dryer

Conversion chart of Pressure dew point and Atmospheric dew point

According to the cooling type, our L series refrigeration compressed air dryer can be divided into two types:
the air-cooled type (F) and the water-cooled one (S).
When considering the final model of the refrigeration compressed air dryer, we need to ensure the following
technical parameters first, such as the real maximum flow capacity(m3/min), the min. inlet pressure(MPA(g)),
the max. inlet temperature (℃), the dew point temperature (℃), and the max. ambient temperature(℃).
Based on the above parameters, please refer to the following chart to get the modulus and put it into the
Pressure dow point ℃

following formula to get the selection capacity.

Technical Specification of RSXB Series Blower Purge Compressed Air Dryer
Reliable Design
Patented Process of RISHENG;
Supportive Ceramic Balls used at the bottom of adsorptio n tower make
uniform air-flow distribution,in this way ,desiccant can be protected
from soaking and also get longer service life,together with special
designed stainless steel flow divider,pressure loss can be greatly reduced.
Special designed high performance desiccant can get best dew point.
Famous blower is with reliable performance and low energy loss.
Pneumatic valves are made by special materials with superb
thermostability,by using double activate solenoid valves ,the reliability

Our patented flow is cryogenic adsorption and cold regeneration.
Porcelain ball in the bottom of tower can make more balance air flow,
which not only prevent desiccant in the bottom from soaking, but
also prolong desiccant life.
Special designed stainless steel dust strainer can greatly reduce
pressure loss.
Special customized high efficiency desiccant can ensure perfect
dew point.
Standard configuration for all range is high efficiency poppet valve,
which reliability and pressure loss are much more superior to thin
film vale, solenoid valve and ect.
Heat exchanger is with high efficiency plate-fin structure which is
imported from the West;
Precooler recovered more than 90% cooling capacity, and reduced
load of evaporator efficiently, so total energy consumption is only
70% of congeneric products.(DPOS：Dew Point OperationSystem)
DPOS energy saving system can prolong adsorption time and
reduce total energy consumption to less than 75%, even in the
fluctuate load condition.
All the adsorption tower, valves, pipings and ect are treated with
refrigeration heat preservation.
Environmental protection refrigerant for all range products, which
compliance with differenet environmental laws of different countries.
