Extremely Dry Air for 200-2000 SCFM Applications

Large Heatless

Engineered for long service life and superior protection of your air-operated equipment and processes, Van Air Systems HL series heatless regenerative desiccant compressed air dryers deliver the peace of mind of high quality, value and fast delivery.

All HL series compressed air dryers include patented Interlock Logic valve sequencing to protect compressed air systems from premature loss of flow or pressure. Interlock Logic guarantees that each phase of the drying cycle is completed before the next can begin. This ensures uninterrupted air flow at constant pressure for downstream equipment and prevents accidental vessel re-pressurization, a vital safety feature.

HL series compressed air dryers have a full range of control features. Standard touchpad controllers (on models HL-2500 and below) include real-time status displays, plus a hold feature to preserve system pressure and conserve energy. The controller also features a switching failure monitor for immediate notification of any cycle disruption.

Optional energy-saving controls, such as Cycle Saver™ and PLC-controlled EMCON II®, automatically adjust cycles to reduce component wear and save energy when air system demand fluctuates.

With many models in stock and ready to ship within 24 hours, rapid delivery from the Van Air factory ensures that an HL series dryer arrives when it’s needed.
