Heatless regenerative desiccant dryers from 7 to 40 cfm

Durable space-savers

Compact DC-HF series desiccant dryers are reliable, quiet and efficient. Thanks to high-quality and generously dimensioned components, these durable space-savers also guarantee impressively low life-cycle costs. 

Configurable operating modes contribute even more energy-saving potential. Flexible compressed air connections and the SIGMA CONTROL SMART controller’s standard-equipped network interface ensure easy installation and integration into the compressed air network.

• PDP down to -94 °F
• Network-capable SIGMA CONTROL SMART controller
• KAESER FILTERS – with ECO-DRAIN on prefilter

Your benefits:

• Durable and reliable unit design 
  The durable design of DC-HF series desiccant dryers is evident thanks to such high-quality features as long-lasting aluminum desiccant tubes, maintenance-free shuttle valves and cartridges filled with a pressure-resistant desiccant material that remains stable in the presence of liquid water. For maximum protection of the desiccant material and the downstream piping network, these compact dryers are equipped with highly efficient KAESER FILTERS.
• High efficiency – ultra-low pressure dew points
  Optimized flow conditions ensure maximum desiccant regeneration capacity for minimal air demand. Even at sustained high load levels, the required pressure dew points (-40/-94°F) are reliably achieved with minimal pressure loss, either in fixed cycles or via Pressure Dew Point Control. Moreover, further energy savings can be achieved if necessary by means of Compressor Synchronization Control or operation in Intermittent mode.
• Quick installation and simple network connection 
  For simple functional checks and swift element changes, efficient KAESER FILTERS are mounted on the outside of the machine. Flexible connections allow them to be attached in variable positions to the upper valve block. The front panel offers simple and convenient access to the valves, silencers and ECO CONTROL SMART controller.

The perfect partner: the KCF oil/water separator

The Kaeser Condensate Filter (KCF) automatically removes lubricant from compressor condensate. This allows for easy and economical disposal of condensate in an environmentally responsible way. The low maintenance system requires no electricity for operation.

Minimize maintenance costs

Where air demand is low, maintenance costs often play a decisive role in achieving lower life-cycle costs. Therein lies one of the DC-HF series desiccant dryer's core strengths; 

in addition to their efficient operation, they also stand out for their particularly long maintenance intervals of 5 years for valves and desiccant material. This makes these durable space-savers especially economical. 

In comparison with conventional dryers, more than 20% of the costs for maintenance parts can be saved, while further savings are contributed by the reduced number of maintenance tasks required for the valves and desiccant material.
