Frequently Asked Questions (FAQ)
Q1: What is a regenerative desiccant air dryer?
A: It’s a twin-tower system that uses desiccant material to remove water vapor from compressed air, automatically regenerating one tower while the other operates.
Q2: What dew point can this dryer achieve?
A: A regenerative desiccant air dryer can achieve dew points as low as -70°C, depending on model and operating conditions.
Q3: What is the difference between heatless and heated types?
A: Heatless models use a portion of dry air for regeneration. Heated models use electric or blower heat, reducing purge loss and improving energy efficiency.
Q4: How often does the desiccant need to be replaced?
A: Typically every 1–2 years under normal conditions. Proper pre-filtration can extend desiccant life.
Q5: Can I use this dryer in high-humidity environments?
A: Yes. The regenerative desiccant air dryer is designed to handle high inlet moisture loads and still deliver ultra-dry air.
