HL Heatless Compressed Air Dryer

Van Air Systems HL Series Regenerative Compressed Air Dryer

When reliable, high purity compressed air is essential, turn to HL series heatless compressed air dryers from Van Air Systems. HL series dryers have been engineered to deliver instrument quality, -40ºF pressure dew point compressed air with unparalleled dependability.

At the heart of every HL series dryer is a patented Interlock Logic 3-way inlet transfer valve. Tested to more than 1 million cycles, every movement of the valve is pneumatically interlocked, guaranteeing precise tower sequencing every time. The
interlocked valve sequencing protects your compressed air system from premature loss of flow or pressure – each phase of the drying cycle must be completed before the next can begin. This ensures uninterrupted air flow at constant pressure for your downstream equipment.

Every HL series dryer sized for 200 – 2000 SCFM comes standard with the robust solid state Touchpad Controller. The Touchpad Controller includes a cycle hold feature for preserving purge air when the compressor unloads. The Cycle Saver and more advanced EMCON II energy saving controllers are also available as options on models HL-200 through HL-2000.

Extremely Dry Compressed Air for 200 - 2000 SCFM
  • 200 through 2,000 SCFM
  • -40° F or -100° F pressure dew point
  • Interlock Logic Sequencing
  • ASME Code vessels
  • Reliable
  • Simple
  • Long service life

Models HL-200 through HL-2000 deliver a low -40° F dew point to protect pneumatic equipment and processes from the harmful and costly effects of compressed air moisture. For even greater protection, these models offer the flexibility of switching to a -100° F dew point when needed. The cycle hold feature preserves system pressure, conserves purge air and saves energy by automatically closing the purge exhaust valve when the compressor unloads or is on standby. It resumes the cycle when compressor flow returns. The cycle monitor also features a membrane panel housed in a NEMA 4X enclosure which clearly displays dryer operation with LED indicators for each step in the cycle sequence.
