desiccant air dryer which use blower regenerated method

Desiccant air dryers are essential in industrial settings—especially where pneumatic equipment, automated production lines, and precision manufacturing demand highly efficient and stable air drying. Designed for energy savings, intelligent control, and reliable long-term operation, these dryers ensure superior compressed air quality for all applications.

Features of Desiccant Air Dryer

1. Wide adaptability: Handles air inlet temperatures up to 40°C, pressure ranges from 0.4MPa to 1.0MPa, and dew point temperatures as low as -40°C to -70°C—meeting diverse industrial needs.
2. Energy-saving & high-efficiency: Equipped with regeneration temperature control, intelligent thermostatic heating, and air blower regeneration for efficient, low-energy drying.
3. Intelligent control system: PLC intelligent control with color touch screen HMI for real-time equipment monitoring, parameter adjustment, RS485 Modbus communication, remote operation, and fault alarms.
4. Multiple safety protections: Includes mechanical temperature switch, outlet pressure switch, and inlet valve status detection for safe operation in harsh conditions.
5. Optimized design: Features stainless steel heater and high-temperature-resistant vortex fan to ensure stability and durability at high temperatures.
6. Accurate dew point control: Built-in dew point control function ensures precise monitoring and adjustment to prevent moisture affecting downstream equipment.

Working Principle

The desiccant air dryer uses adsorbents (molecular sieve, silica gel, etc.) to remove moisture from compressed air in an adsorption tower. Periodic regeneration restores the adsorbent’s moisture-absorbing ability by heating and passing air through the tower, releasing captured moisture. A PLC-controlled system manages temperature, humidity, and safety functions, ensuring stable and efficient operation with minimal energy consumption.
