Description
AR 425P6 Premium Cycling Refrigerated Air Dryer
The ELGi Airmate AR 425P6 is a cycling refrigerated air dryer engineered to remove moisture from compressed air while reducing energy use at part‑load operation. Cycling dryers use thermal storage (glycol thermal mass) to allow the refrigeration system to cycle on and off as demand changes.
This series is designed to maintain a stable pressure dew point while aligning compressor run time with load requirements. A smart controller provides dew point visibility and indicates energy‑saving (ECO) operation for easier monitoring.
Key Features
- Cycling refrigerated design: Glycol thermal mass supports cycling operation and energy savings when air demand drops.
- Smart controller visibility: Displays pressure dew point temperature and indicates ECO/energy‑saving operation.
- Integrated system components: Certain capacity ranges include built‑in pre/after filtration to reduce external piping (when configured).
- Efficient heat exchange: Plate‑type heat exchanger design supports strong thermal efficiency and low pressure drop.
- Automatic condensate removal: Float (mechanical level sensing) drain design supports reliable moisture discharge.
- Compliance focused package: Designed for industrial refrigerated drying applications with common North American installation requirements.

Benefits
- Lowers operating cost at part load: Cycling operation reduces unnecessary refrigeration compressor run time.
- Supports consistent air quality: Refrigerated drying helps prevent water carryover and condensation in plant air systems.
- Simplifies install and service planning: Integrated filtration (where included) and controller visibility help streamline maintenance.
- Quick fit into existing piping: 2" NPT connections support common installations.
Installation & Application Notes
- Rated capacity is typically stated at nominal conditions (100°F ambient, 100°F inlet air, 100 psig) unless otherwise noted.
- Provide proper inlet filtration and condensate management to protect downstream equipment and maintain dryer performance.
- Verify drain piping is properly routed and that the drain actuates during commissioning.
- If your configuration includes filters, plan periodic element changes; reference annual kit B009408170030 when applicable.
- Allow service clearance for condenser cleaning, electrical access, and routine inspection.
The AR 425P6 is a strong choice for facilities that want refrigerated drying with cycling energy savings and straightforward monitoring.
Frequently Asked Questions
AR 425P6 Premium Cycling Refrigerated Air Dryer
▶️ Question: What makes a cycling refrigerated dryer different from a non‑cycling dryer?
Answer: Cycling dryers use thermal storage (often glycol) so the refrigeration system can cycle off when demand is low. This typically reduces energy use compared with continuous‑run refrigeration.
▶️ Question: What dew point should I expect from this dryer?
Answer: This model is designed around a refrigerated dryer dew point of about 38°F (Pressure Dew Point) under rated conditions. Real‑world dew point can vary with inlet temperature, ambient conditions, and airflow.
▶️ Question: Does this dryer include filters?
Answer: Some model ranges are available with integrated pre/after filtration to reduce external piping. Confirm your exact configuration and accessories list for included filtration.
▶️ Question: How should I maintain the condensate drain?
Answer: Verify the Float (mechanical level sensing) drain actuates and discharges condensate as intended. Keep drain lines clear and route them to an appropriate condensate management system.
▶️ Question: How do I plan filter maintenance if filters are included?
Answer: If your configuration includes filters, plan periodic element changes and keep a replacement kit on hand. Where listed, kit B009408170030 supports annual service planning.
