Hankison PHDM 59 – Heatless Modular Desiccant Air Dryer
High-Capacity Drying. Modular Efficiency. Reliable -40°F Dew Point Protection.
The Hankison PHDM 59 Heatless Modular Desiccant Air Dryer delivers dependable, clean, ultra-dry compressed air in a compact and energy-efficient form. Designed for demanding applications—laboratories, medical facilities, pharmaceutical production, automation systems, CNC machinery, and industrial environments—the PHDM 59 provides exceptional moisture control without the bulk or complexity of traditional twin-tower dryers.
Built to provide a consistent ISO 8573-1:2010 Class 2 pressure dew point of -40°F, this dryer protects sensitive pneumatic tools, valves, robotics, instrumentation, coatings, and processes from moisture-related contamination, corrosion, and downtime. With a 59 SCFM @ 100 PSI flow capacity, the PHDM 59 is ideal for mid-sized compressed air systems requiring reliable, continuous moisture removal.
Purchasing through Compressed Air Advisors Online—America’s choice for compressed air solutions—gives you expert guidance, nationwide support, and access to top-tier industrial air treatment products.

How the PHDM 59 Works
The PHDM Series utilizes a dual-tower desiccant regeneration process:
-
Tower 1 dries the incoming compressed air.
-
Tower 2 simultaneously regenerates via a controlled purge cycle.
-
After each timed cycle, the towers automatically switch roles.
-
Continuous, heater-less operation ensures simple, trouble-free performance.
