FLEX Series – Refrigerated Air Dryers 75 to 2000 SCFM
Energy Saving Sustainability
The FLEX Series lowers air system power costs and improves productivity by matching power consumption to compressed air demand. In a typical manufacturing facility, up to 30% of the electricity consumed is for generating and treating compressed air. To reduce the total cost of operation and qualify for utility company incentive programs, proper air treatment equipment selection and application is required.
Load Matching Performance
Compressed air load profiles in most manufacturing facilities fluctuate. The FLEX Series provides cost-effective energy savings by matching electrical power consumed in direct proportion to air demand. Linear load matching is achieved from 0% up to 100% demand. Non-cycling dryers operate with the refrigeration compressor running continuously, regardless of inlet load conditions. Minimal energy savings are realized from 100% down to 0% inlet air load.
How it Works
The FLEX Series utilizes a phase change (PCM) heat transfer medium between the refrigeration and compressed air circuits that serve as a reservoir for thermal storage. The thermal reservoir is comprised of a 3-in-1 heat exchanger (patent pending) filled with a phase change material that efficiently transfers heat energy through a “change of state.” Phase Change: changing from liquid to solid back to liquid in a continuous cycle. The refrigeration circuit operates to cool down the PCM until it forms into a solid at which time the refrigeration system cycles off. As the compressed air enters the PCM to air section of the heat exchanger, the PCM media absorbs heat for the airstream and begins to melt the PCM media at a constant temperature. 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. This cycle repeats as required to meet the corresponding compressed air load on the FLEX dryer.
