Heated Air Dryer For Compressed Air System 120m3/min

Tips: Due to the wide variety of air dryer, it may not be possible to display them all on the website. If you need any, please contact us by email or phone.

The Heated Air Dryer for Compressed Air System 120m3/min operates on the principle of pressure swing adsorption (PSA) with heated regeneration. It consists of two towers filled with desiccant material (typically activated alumina or silica gel). While one tower adsorbs moisture from the compressed air, the other undergoes regeneration using heated ambient air supplied by a blower.

Working Principle:

1.Adsorption Phase: Wet compressed air enters the adsorption tower, where moisture is trapped by the desiccant bed. Dry air exits the system.

2.Regeneration Phase:

Heating: Ambient air is heated and passed through the saturated desiccant bed to evaporate and remove moisture.

Cooling: The bed is cooled using dry air to prepare for the next adsorption cycle.

Switchover: Valves automatically switch between towers to ensure continuous dry air output.

This dryer is equipped with safety bypass valves, relief valves, and inline check valves for reliable operation. Its integrated design allows for easy installation and minimal maintenance.

1.Robust Construction

Features high-quality valves and heaters for durability and long service life. The desiccant bed is designed for minimal dusting and extended life.

2.Low Operating Costs

Long switching cycles (4-8 hours) reduce wear and tear on components. Minimal purge air consumption lowers overall operating costs.

3.Safety and Reliability

Includes multiple safety features such as bypass valves, relief valves, and alarms for secure operation. PLC-based control allows for automated and precise operation.

4.Easy Maintenance

Integrated design with accessible components for straightforward servicing.

1.Electronics Manufacturing

Prevents moisture damage during circuit board production and assembly.

2.Food and Beverage Processing

Ensures air quality meets hygiene standards for packaging and handling.

3.Pharmaceuticals

Provides oil-free dry air for manufacturing and packaging processes.

4.Chemical and Petrochemical

Protects instruments and processes from corrosion and contamination.

5.Power and Industrial Plants

Used for instrument air and control systems.

1.Startup

Check valve positions and ensure the system is pressurized gradually.

Set the switching cycle (typically 4-8 hours) using the PLC controller.

2.Normal Operation

Monitor pressure dew point and system pressure drop.

Check for alarms or alerts on the control panel.

3.Regeneration Phase

The Heated Air Dryer for Compressed Air System 120m3/min automatically switches towers for regeneration.

Heating and cooling are controlled to ensure complete desiccant reactivation.

4.Shutdown

Follow proper shutdown procedures to avoid moisture retention in the desiccant beds.
