Hankison HPRN-100 Air Dryer

The Hankison HPRN-100 is an industrial-grade non-cycling refrigerated air dryer engineered to provide a consistent 38°F (+3°C) pressure dew point for high-demand pneumatic systems. Operating at 115V single-phase power, this unit delivers a 100 SCFM capacity and serves as the direct HPR-100 replacement, featuring an upgraded user interface and a 316 stainless steel brazed plate heat exchanger. The cross-flow heat exchanger design minimizes pressure drop while maximizing thermal efficiency across 0% to 100% flow conditions. This Hankison air dryer utilizes R-134a refrigerant and a hot gas bypass valve to prevent evaporator freeze-up during low-load periods, ensuring stable performance. A timer-operated drain valve with an integrated Y-strainer and a dew point indicator are standard, allowing for precise condensate management and at-a-glance system monitoring. Built for long-term reliability in professional compressed air treatment applications, the HPRN-100 includes 1" male NPT connections for seamless integration into existing 100 SCFM compressor lineups.

• Optimized Moisture Removal: Achieves ISO 8573-1 Air Quality Class 4-5 dew points using a specialized demister/separator.
• Advanced Heat Transfer: Herringbone geometry stamped into stainless steel plates creates turbulent flow for a self-cleaning effect and high thermal efficiency.
• Durable Construction: Features a powder-coated steel cabinet and a replaceable ambient air filter to protect the condenser from industrial contaminants.
• Simplified Maintenance: Equipped with an electronic drain valve and panel-mounted controls that allow for maintenance directly from the interface.

Common Questions

Does the HPRN-100 require a pre-filter for operation?
While the unit is built for durability, installing a high-efficiency coalescing filter upstream is recommended to prevent oil and large particulate from fouling the brazed plate heat exchanger.

Is this unit compatible with three-phase power systems?
No, the HPRN-100 is specifically designed for 115Vac, 60 Hz, Single Phase electrical infrastructures common in smaller shops and localized compressor rooms.

How does the non-cycling design benefit my air system?
The non-cycling refrigerated dryer design ensures the refrigerant compressor runs continuously to maintain a steady dew point, preventing the temperature spikes often seen in cycling units during varying load cycles.
