As regenerating, in order to temporary lower the desiccant absorption ability to let the water molecule effuse out, about 7% dry air will go through the regeneration tower slowly after the air being heated up to 150℃, the stored heat also will take part in regeneration process for energy saving. For the circular employ ofabsorption-regeneration-absorption, the desiccant dries compressed air continuously to get deeply dried air. The technical performance already has reached the international high-level standard. It can be you ideal equipment with dew point lowering than -40℃.The working alternating cycle of twin tower can ensure stable output of satisfied compressed air. Its pressure dew point which can make up to -40℃is definitely can meet the high quality requirements of users. Due to the heater, it can keep good regeneration performance with less purge air loss.3）Configuration Process of Heated Regeneration Air Dryer4）Main Component IllustrationInlet Air Temperature 20-45℃Inlet Air Oil Content ≤0.1PPM Working Pressure 0.6-1.0MPa Dew Point ≤-40℃Regeneration Air Purge Loss 6%-8% Power Supply 1-6(Nm3/min)：AC220V 50HZ8(Nm3/min) andabove：AC380/220V50HZ6）Technical Requirementsa ）Matching Application of Heated Regeneration Air Dryerb ）During absorption process, desiccant is sensitive with the quality of inlet air: the oil content of the inlet air should be lower than 0.1PPM, otherwise, it will give an influence on the absorption performance, what ’s worse, it will reduce desiccant ’s lifespan and make an irretrievable damage.c ）In order to meet production need without any impact on continuous manufacturing, such as dryer maintenance and repairing, we suggest customers select by-pass system to equip at air inlet and outlet place.d ）When inlet air pressure changes, the capacity of air dryer should be recalculate with the following correction coefficient table.After CoolerBuffer Tank罐Water SeparatorScrew/Centrifugal Air CompressorHC-level FilterHigh Efficient Oil RemoverHeated Regeneration Air DryerDust FilterHA-level FilterTreated Compressed Air SourcePiston Air Compressor HC-level FilterAttention —Equipment Reasonable Configuration In order to reach the specific required performance and to avoid unnecessary faults,please take matching application configuration as reference.e）In order to win 5 to 10 minutes buffer time under the situation of unexpected blackout, we suggest our customers select air receiver equipped before the dryer.f）When there are several air compressors in the compressor room, the outlet pipe of every air compressor should all be quipped with check valve and isolating valve.7）Before and after the air dryer, we suggest our customers deploy air flow gauge, pressure gauge and temperature gauge for detecting and recording use.8）Please open the drainage valve at the bottom of the tower to drain for each start or shutdown.2、Operation Instruction of the Controller1）Parameters SettingPlease turn DIPSW on the left position (setting mode) to enter into controller parameter setting status.
