Q&A

1. Have a stable and consistent outlet pressure dew point

■ Reasonable cylinder design ensures that the contact time between compressed air and desiccant is 4.8 seconds, which meets the dew point requirement of the finished air. 30% desiccant balance is used to compensate the natural aging of desiccantand ensure the drying effect.

■ Large diffuser to ensure that the airflow passes through the desiccant layer evenly, eliminating the phenomenon of channel flow.


2. The loss of regeneration air is less than 12%

■ Excellent barrel design, save 95% of the heat of adsorption, the stored heat is used to increase the temperature of the regeneration air in the regeneration stage, improve the desorption capacity of the equipment, and make the regeneration more thorough.

■ The reverse convection method is used for drying and regeneration, and the best effect is when the moist air flows through the dried adsorbent.

■ The amount of regeneration air can be adjusted according to the operating load demand of the dryer.


3. Long service life of desiccant

■ Appropriate barrel size keeps the flow rate and time of the air through the desiccant layer in the best condition, and fully exerts the performance of the desiccant.

■ Reasonable system configuration, before the airflow enters the barrel, the oil content and heavy pollutants in the airflow are removed immediately by the efficient degreasing treatment to avoid the pollution of the desiccant layer.


What material are your air tanks made of?
We have carbon steel and stainless steel.
How to choose between microthermal and heatless adsorption dryers?
In general, it is enough to choose the microthermal suction dryer, which consumes less compressed air than the heatless adsorption dryer, so the economy is better.
Why should the air handling capacity of a dryer be greater than the compressor discharge?
Because the dew point temperature of the air has to be taken into account. Compressed air, after passing through the compressor, contains a certain amount of water vapor. The dryer needs to remove this excess water to bring the compressed air to the desired dew point temperature. If the dryer's capacity is the same as the compressor's exhaust volume, the air may not be dried sufficiently during the process due to insufficient margin, resulting in a final compressed air quality that does not meet the requirements.
How much more air is handled by the dryer than is discharged by the compressor?
The air handling capacity of the dryer should be about 1.25 times the exhaust volume of the compressor.
What is the principle of water removal in a refrigerated dryer?
Condensation to remove water, the refrigerated dryer by reducing the temperature of the compressed air, so that the air's water storage capacity deteriorates, and the water that can not be stored becomes liquid and is removed from the compressor.
What is the refrigerant in a refrigerated dryer?
R22
What is the maximum inlet temperature for a high temperature refrigeration dryer?
80℃
What is the pressure dew point of a high temperature refrigerated dryer?
2-10℃
What is the desiccant of an adsorption dryer?
Activated alumina + molecular sieve
What is the filter cartridge replacement interval?
