Van Air HLS Heatless Regenerative Desiccant Air Dryers

Models HLS-55 through HLS-150 delivery 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 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.
