Hankison HPR-25 Air Dryer

The Hankison HPR-25 Air Dryer is a heavy-duty, non-cycling refrigerated solution engineered for industrial-grade moisture removal in compressed air systems. Maintaining a consistent 38°F pressure dew point, this unit effectively prevents downstream contamination and equipment corrosion by stripping water vapor from 25 SCFM airflows. Designed for rugged performance, the HPR-25 utilizes a smooth bore copper tube-on-tube heat exchanger to ensure high thermal efficiency with minimal pressure drop, typically under 5 psig at rated conditions. This 115V single-phase model is a direct replacement for 2815-004, HKN-HPR-25, HKN-HPRP-25, and K-8025 air dryers, making it a drop-in upgrade for existing 3/4-inch NPT lines. Equipped with an integrated centrifugal separator and a reliable electronic timed drain, the HPR-25 refrigerated dryer offers superior condensate management without the need for complex cooling fans, thanks to its quiet-running static condenser design. This unit is built into a compact, epoxy-coated steel cabinet to withstand harsh mechanical room environments while utilizing environmentally friendly R-134a refrigerant.

• Stable Dew Point Control: Achieves a steady 38°F (3°C) dew point to protect pneumatic tools and sensitive instruments from liquid water.
• High-Efficiency Heat Exchange: Copper tube-on-tube design maximizes heat transfer while maintaining a low-profile pressure drop.
• Automatic Condensate Removal: Features a timed electronic drain valve and centrifugal separator to eliminate moisture across varying inlet loads.
• Direct Drop-In Compatibility: Standard 3/4-inch NPT connections and 115V power allow for seamless replacement of legacy Hankison HPR series models.
• Maintenance-Friendly Design: No internal mesh to foul and a fanless static condenser reduce service intervals and operational noise.

What is the maximum inlet temperature for the HPR-25?
The unit is rated for a maximum inlet air temperature of 120°F (49°C) and a maximum ambient temperature of 110°F (43°C).

Can this dryer replace the older HKN-HPR-25 models?
Yes, the HPR-25 is the current technical equivalent for legacy part numbers 2815-004, HKN-HPR-25, HKN-HPRP-25, and K-8025.

Does this unit include an integrated drain?
Yes, the HPR-25 comes standard with an automatic electronic drain valve to ensure consistent moisture expulsion without manual intervention.
