PCM Air Dryer
Phase change type air dryer, it only runs when it's needed, so the cost of electricity is 1/10
No more refrigeration dryer that runs all the time!
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 of OFF according to varying compressed air heat loads.

- Adapted Phase Change Material PCM (Patented)
- Stainless steel brazed plate heat exchanger with PCM filled in
- Automatically triggers refrigeration compressor to switch ON or OFF according to varying compressed air heat loads
- Up to 99% energy saving with the lowest cost
- Shortest period of return of investment
- Electrostatic capacity sensor
- Zero loss of compressed air when condensate water is discharged
- Automatically switch to timer mode at malfunction
- Integrated Cold Coalescing oil removal filter
- 99.8% oil removal efficiency
- When used with NGF filter installed upstream and filter element replacement had been in accordance with recommended maintenance
- Heat Exchanger replacement is confined to its leakage or blockage problem
Phase change in PCM dryer
- When a refrigeration compressor and condenser fan are running, the cold refrigerant in the chiller (evaporator) cools the liquid Phase Change Material(PCM) and it gradually freezes.
- When a PCM is sufficiently cooled and frozen, the refrigeration compressor and condenser fan stop.
- The compressed air is continuously cooled by the PCM while the refrigeration compressor is inactive. No power is consumed during this period.
- The PCM gradually melts as it adsorbs heat from the compressed air, and when fully melted, the refrigeration compressor and condenser fan resume to cool down the PCM.
- Compressed air saturated with water vapour enters the stainless steel brazed 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 vapour condenses into liquid droplets which are then removed by high efficiency external moisture separator with No Loss Drain.
- Then aerosol and oil mist condensed from oil vapour are removed by high efficiency external oil filter with a No Loss Drain.
- Chilled air returns through air-to-air heat exchanger (re-heater) where it is reaheated before exiting the dryer. This is to prevent external sweating of piping when clean and dry compressed air travels to point of use.
