Operation Principle
Two columns of adsorption dryers are filled with a special moisture-absorbing substance—adsorbent (active aluminum oxide, zeolite, silica gel). Let’s consider the operation principle of this equipment in detail:
- The cold regenerated adsorption dryer receives a compressor-pressurized stream of moist air, which passes through a layer of adsorbent material under pressure, and the moisture is absorbed by it, resulting in dried compressed air at the outlet.
- In parallel, another column receives a small portion of compressed dry air, which regenerates the adsorbent.
- Dry air is then fed to the dryer outlet and further into the pipeline system.
- All drying processes are controlled, and operational indications are given to an operator via a control panel consisting of a PLC, an operator panel, valves, and sensors.
In cold regeneration, a portion of dried compressed air is used to regenerate the adsorbent. It is fed into the desiccant bed in such a way that dry air absorbs the accumulated moisture and removes it. The regeneration process is then carried out without heating.
Cold Regenerated Adsorption Dryer Components
Equipment main components:
- Pressure gauge.
- Pressure vessel.
- Automated control system.
- Inlet/outlet air filtration system.
- Pneumatic silencer.
- Pneumatic air supply valves.
Cold Regenerated Adsorption Dryer Advantages
The unit features the following characteristics:
- Easy installation and operation.
- Compact dimensions.
- The set dew point precise maintenance at -40°C.
- Long production life due to the adsorber’s durability.
- Significantly lower equipment cost compared to heat regeneration dryers.
- Compressed air losses for regeneration at nominal capacity and pressure are no more than 10-15%.
- Compact dryer dimensions allow you to install it in a container or in closed premises.
In addition, dryer units can be optionally equipped with following instrumentation and automation:
- inlet and outlet air pressure sensors;
- outlet air dew point sensor;
- outlet air temperature sensor;
- outlet air flowmeter.
What benefits do you get from this? For example, adding a dew point sensor or flow meter allows you to manage cycle times and operate your equipment more efficiently and optimize energy costs in your facility. Our cold regeneration adsorption dryer uses activated aluminum oxide as the adsorbent. Optionally, silica gel can be used.
