PCM Compressed Air Dryer
From 20HP to 3200HP and larger PCM Series is the ultimate solution providing perfect dehydration and enormous energy savings.
This PCM technology harnesses the latent heat occurs when PCM converts solid to liquid or liquid to solid, which automatically triggers the refrigeration compressor to switch On/Off according to varying compressed air heat loads.
How it works
Phase Change in PCM Air Dryer
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 from 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 com pressed air load on the FLEX dryer.
PMC 2.8 to 16.5
- Compressed air saturated with water vapor enters the stainless steel brazed plate air-to-air heat exchanger, is pre-cooled by the outgoing chilled air, and then directed to the stainless steel brazed plate PCM-to-air heat exchanger (evaporator) where it is further cooled by the Phase Change Material (PCM).
- As the air is cooled, water vapor condenses into liquid droplets which are then removed by high efficiency integral moisture separator with No Loss Drain.
- Chilled air returns through air-to-air heat exchanger (reheater) where it is reheated before exiting the air dryer. This is to prevent external sweating of piping when clean and dry compressed air travels to point of use.

Energy Saving Solutions
The PCM 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 PCM 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
PCM 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, at 40% energy savings.
