BPD Heated Blower Purge Regenerative Desiccant Air Dryer we design and produce for energy savings and consistent operation automatically controlled via PLC and touch screen. It uses a high efficiency blower to take in ambient air required during the heat regeneration cycle to adsorb moisture from the desiccant.
Comparing Heatless and Heated purge, the heated blower purge reduce the dry compressed air is used during the dry air cooling regeneration period for reduced heat and dew point spike at tower switchover. And the unique parallel cooling mode further reduces the heat and dew point spike prior to tower switchover.
BPD Heated Blower Purge Regenerative Desiccant Air Dryer adopts early heat regeneration termination feature. This feature terminates the heat regeneration early and eliminates the unnecessary heater and blower on-time saving energy.
Features
1. Automatically adjusts the regeneration cycle maintaining dew point and extending the drying cycle
2. Switching is less frequent, reducing dryer maintenance and fully utilizing desiccant capacity
3. Bigger purge tower and lower airflow speed improve improve reliability and performance of purge.
4. Heating regeneration cycle takes in ambient air, no compressed air is used during this phase.
5. PLC programmable controlling system, NEMA 4steel enclosure, easy operation and easy reading.
7. 6. Interlocked protective system, safety and reliable
