FLEX Series - Refrigerated Air Dryers 75 to 2000 scfm

DRYERS - COMPRESSED AIR / REFRIGERATED COMPRESSED AIR DRYERS

FLEX Series Sustainable Energy Saving Solution

Features

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 electricity consumed is for generating and treating compressed air. To reduce 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.

Linear Energy Savings

FLEX Series dryers automatically cycle (on /off) the refrigeration compressor in response to inlet load conditions. As the inlet air load is reduced, the power requirement to dry the air is matched in proportion to the demand. For example, at 60% inlet air load, a non-cycling dryer consumes 96% of the full load power consumption, a 4% energy savings. By comparison, at 60% inlet air load, the FLEX Series consumes only 60% of the full load power, a 40% energy savings.

Theory of Operation

How It Works

  1.  The FLEX Series utilizes a phase change (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 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

  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 for the airstream and begins to melt 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 FLEX dryer.
