DFX Series - Refrigerated Compressed Air Dryers 3,000 – 12,000 SCFM

The DFX Series dryers feature a unique design that incorporates a 3-in-1 heat exchanger (pending patent).

1. The DFX Series utilizes a phase change material (PCM) heat transfer medium between the refrigeration and compressed air circuits that serves as a reservoir for thermal storage.
2. The thermal reservoir is comprised of a patent pending heat exchanger filled with a phase change material that efficiently transfers heat energy through a “change of state”. The PCM changes from liquid to solid back to liquid in a continuous cycle.
3. The refrigeration circuit operates to cool down the PCM until it forms into a solid at which time the refrigeration system cycles off.
4. As the compressed air enters the PCM to air section of the heat exchanger, the PCM media absorbs heat from the airstream and begins to thaw the PCM media at a constant temperature.
5. When most of the PCM media has turned to liquid the refrigeration system cycles on to again cool down the PCM media turning it back into a solid.
6. This cycle repeats as required to meet the corresponding compressed air load on the DFX Series dryer.
7. This innovative approach to heat exchange in the DFX Series dryers demonstrates a significant advancement in temperature regulation technology.
