CDHM Series

Dual Tower Desiccant Air Dryers

The CDHM Series desiccant air dryers use the proven “Pressure Swing Adsorption” (PSA) method for drying wet compressed air. This requires having two identical towers containing hygroscopic desiccant. The unique design of the CDHM Series allows for the dryer to start and stop with a compressor or point-of-use equipment to eliminate purge loss when off. The solid-state memory feature allows the dryer to start where it left off in the drying cycle to prevent wet air downstream.

BENEFITS

Solid-state timer with LED display for visual monitoring
Built-in timer memory
Low-velocity air through the desiccant for more efficient drying
Large internal air passages to reduce pressure drop
NEMA 4 components (protects against water spray and dust)
Minimal threaded connections for fewer leak points than competitive units
Easy change out desiccant cartridges
Components are all easily serviced and field-replaceable – no special tools
Full repressurization before tower switch-over causes less shocking of the desiccant and no pressure fluctuation
No plug mufflers – will not rupture or reduce dryer efficiency
6-ft. electric power cord
