dryers

When reliable, high purity compressed air is essential, turn to HD series heatless compressed air dryers. HD series dryers have been engineered to deliver instrument quality, -100º F pressure dew point compressed air with unparalleled dependability.

At the heart of every HD, 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 HD series dryer sized for 200 – 3000 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.  dryers come standard with the Cycle Saver dew point demand switching controller, which reduces unnecessary purging under

low flow and low moisture load conditions. The Cycle Saver and more advanced EMCON II energy saving controllers are also available as options on models
