Description
Altec AIR HRL-0025 Heatless Desiccant Air Dryer
The Altec AIR HRL Series consists of high-capacity regenerative (heatless) desiccant air dryers designed to meet the needs of the industrial compressed air market. Model HRL-0025-1 is rated for 25 SCFM @ 100 PSIG.
Standard equipment includes ASME / CRN approved pressure vessels, factory installed filters with differential pressure gauges and a pre-filter timer drain, E-Z switching valves for extreme valve life, and an ETL listed Pro-Logic controller with a NEMA 4 enclosure. Regulated purge flow helps maintain optimum settings regardless of operating pressure, and -40°F/C outlet dew point air is standard.

Benefits
- Industrial-grade construction: ASME / CRN pressure vessels and bolt-down construction support demanding installations.
- Moisture control performance: -40°F/C outlet dew point is standard for the HRL Series.
- Service visibility: Differential pressure gauges and a pre-filter timer drain help support routine maintenance.
- Reliable cycling components: E-Z switching valves are designed for extreme valve life.
- Consistent purge settings: Regulated purge flow helps maintain optimum settings regardless of operating pressure.
Installation & Application Notes
- Sizing is based on the Compressed Air and Gas Institute (CAGI) ADF 200 Standard for compressed air at 100 PSIG inlet pressure and 100°F inlet temperature with a -40°F pressure dew point.
- For inlet pressures other than 100 PSIG, maximum inlet flow (-40°F/C PDP) = INLET Flow × INLET Flow Factor (A) at actual pressure (see multiplier table).
- 150 PSIG is standard maximum inlet pressure; for inlet pressures that exceed the HRL standard input, contact Altec AIR for assistance.
The Altec AIR HRL-0025 is a heatless desiccant air dryer configuration rated for 25 SCFM @ 100 PSIG with approximately 3.75 SCFM purge and 1/2" NPT connections.
Frequently Asked Questions
Altec AIR HRL-0025 Heatless Desiccant Air Dryer
▶️ Question: What inlet conditions is the HRL flow rating based on?
Answer: Sizing is based on the CAGI ADF 200 Standard for compressed air at 100 PSIG inlet pressure and 100°F inlet temperature with a -40°F pressure dew point.
▶️ Question: How do I size for inlet pressures other than 100 PSIG?
Answer: Use the multiplier table: maximum inlet flow (-40°F/C PDP) = INLET Flow × INLET Flow Factor (A) at your actual inlet pressure.
