DC-HF Series 7 to 40 cfm

Heatless Regenerative Desiccant Dryers

Superior moisture removal in low flow applications

Twin tower desiccant dryers deliver the low pressure dew points needed for the most moisture sensitive applications or when the compressed air piping will be exposed to cold temperatures. Since desiccant dryers are more expensive to operate, it makes sense to only use them for the application that requires them. DC-HF series desiccant dryers make it possible to dry smaller flows just where you need them. They are ideal for point of use applications.

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°F/-94°F) are reliably achieved with minimal pressure loss, either in fixed cycles or via pressure dew point control. Multiple control modes offer further energy savings.
The towers are designed to limit the air velocity. This prevents bed fluidization, desiccant dusting, and ensures proper contact time between the air and desiccant.

Reliable drying and filtration

The durable design of DC-HF 2.0 – 11.3 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. These dryers come standard with a coalescing pre-filter and a dust collecting after- filter to trap desiccant dust.

Convenient installation

DC-HF series dryers are furnished in ready-to-mount cabinets. They arrive completely assembled, piped, wired, and fully charged with desiccant. Simply make the utility connections and the air dryer is ready for operation.
Wall or floor mount options. Multiple filter connection configurations give you flexibility when facing limited space. For simple functional checks and swift element changes, efficient Kaeser filters are mounted on the outside of the machine, The electronic Eco-Drain condensate drain is delivered fully wired. When service is needed, the front panel offers fast, convenient access to the desiccant cartridges, valves, and silencers.

Network connection

The Eco Control Smart controller provides floating message contacts, and a Modbus TCP interface is standard. DC-HF series desiccant dryers can be connected to a Sigma Air Manager 4.0 or other plant control systems. Operating parameters and messages can be monitored remotely in real-time.
