Knight Pneumatics offers Van Air HL Series heatless regenerative dryers that can be supplied with a range of control options to suit specific applications.
All Van Air HL Series heatless regenerative dryers 200 scfm and larger include the hold feature and switching failure monitor.
The hold feature maintains system pressure and conserves purge air by the closing action of the purge exhaust valve when the compressor unloads or is on standby. The switching failure monitor ensures instant warning of disruption of operation cycle to ensure a fast response.
There is a selection of control options available with HL Series heatless regenerative dryers including the standard controller included with models HL-200 to 2500 Touchpad controllers with real-time status display.
The cycle saver is included on models HL-300 and larger. They are optional on models under 3000 scfm.
EMCON II energy management control is optional on all regenerative dryer models. This control adjusts purge to actual moisture load conditions for maximum savings, lowest possible operating cost and a -40°F dew point.
