Compressed air is fed into the dryer and is pre-cooled in the air-to-air heat exchanger by the outgoing cold compressed air.

The pre-cooled air then passes through the refrigerant-to-air heat exchanger where it is further cooled to the required pressure dew point.

The moisture in the compressed air condenses out and is collected and discharged automatically. Finally, the cold discharged air is rewarmed by the incoming compressed air. This saves energy and prevents any moisture forming beyond the dryer in the compressed air system.

 Ultrapulse: State of the art in fridge dryer regulation

This microprocessor-based control device is the heart of this generation of fridge dryers.

By monitoring parameters such as cooling temperature, pressure in the fridge circuit as well as dryer specific parameters, the actual operational condition of the dryer is calculated. If indicated by the measured data, the fridge compressor will be shut off for a pre-calculated period.

The pulsating measuring of the temperature (several times per second) and the use of the aluminium heat exchanger as a storage mass ensures a quick response to load changes without risking dewpoint spikes above the set level. In addition, the processor controls monitors the condensate drain which works without loss of compressed air

  • Important advantages of the dryer generation
  • Ultrapulse-controlling from SD 0100 AP as standard
  • Multi Functional Display load controlled energy consumption,
  • reduction down to 10% of nominal energy consumption load
  • controlled drain low voltage monitoring
  • Display is changeable from °C to °F 
  • High operation parameters
  • Environmentally friendly refrigerant R-134a
  • Compact and easy to install cabinet

The Multi Functional Display shows all relevant parameters:

  • Current pressure dewpoint
  • Operation mode Normal/Summer/Automatic Power consumption related to the whole life time Alarm signal Alarm history
  • Maintenance necessary Operation status of the drain Operation hours
  • Fridge compressor on/off Current energy consumption
