Compressed air water removal solution
Thread Content
After the compressed air used for instruments in our production has been processed by filters and heatless regeneration dryers, there is still water in the air. Is there a more complete solution?
Have you used a cold dryer? Normal requirements: -40C under normal pressure
The air treated by the heatless regeneration drying system can achieve the treatment effect of -40 degrees Celsius, and its dew point can reach -40--70 degrees Celsius.； The most likely cause of this situation is that there is a problem with the operation of the heatless regeneration drying treatment system. The adsorption system is saturated and cannot switch to regeneration in time.
There is something wrong with your heatless regeneration dryer. Check it and replace the silica gel inside. It should be fine.
Using a cold dryer consumes too much power. My current approach is to install an extra set of regenerative dryers and connect them in series to improve the situation of water in the air. But I don't use silica gel. I buy molecular sieves, which works very well.
If the compressed air contains water, there must be a problem with the desiccant and it should be regenerated. The compressed air drying solution can be carried out step by step. First, use a cold dryer for cooling and drying. The processing temperature can be adjusted according to the actual situation, and then use a heatless regeneration or slightly hot regeneration dryer for drying to achieve the required drying degree. It may be more economical to use molecular sieves as desiccants.
