DHC Desiccant Dryer
At a Glance
Why Heat of Compression?+ -
The DHC Series heat of compression desiccant air dryers from Gardner Denver provide an energy efficient solution to remove moisture from compressed air. Thermal energy generated during the air compression process of the compressor is utilized to regenerate the offline desiccant tower. Consuming under 50 watts, the energy efficient design offers the lowest cost of operation when compared to conventional dehydration technologies. Ideally positioned for use with oil-free compressors, the DHC Series turns “waste heat” into energy savings that will directly impact the bottom line.
Take Control of Monitoring+ -
The controller for the DHC Series is equipped with a comprehensive diagnostic system that provides real-time operating status, service reminders and fault conditions. Information is communicated to the user with a highly visible two line, sixteen character vacuum florescent text display screen. The dryer comes furnished with solid-state controls located in a polycarbonate, NEMA4/4X, IP66 rated enclosure. The controller includes an RS 232 communications port and Modbus registers for remote monitoring. As standard, voltage-free dry contacts provide remote alarm capabilities.
Optional Dew Point Demand Control System+ -
A dew point demand control system automatically extends the drying cycle to compensate for changes in operating conditions. By sampling the compressed air exiting the drying tower, the demand control system delays tower switchover until the moisture content at the sample port rises to the predetermined set point.
