Fridge Dryers

Compressed air filtration


THE FRIDGE DRYER makes possible to treat the air coming from a compressor by lowering the dewpoint of water to 3°C (37.4°F) and to ensure a quality of air in conformity with the standard ISO 8573.1 Class 1.4.1.

It is advised for : All analytical instruments where moisture in too great quantity can be problematic.

Reference : CQ 00(Air flow rate)A



Quality of the air obtained

ISO8573.1 Class 1.4.1.
– Water dewpoint 3°C (37.4°F)
– HCs non CH4 < 0.01 ppm.
– particles < 0.1 micron.


Without danger to the environment

The cooling agent used R134a is inoffensive and not polluting.


Easy maintenance

Frontal access to all the elements.


Compact, easy to install


Timer controlled solenoid valve to drain the condensates.


High operating temperature

Until 60°C (140°F) in compressed air and 50°C (122°F) in ambient air thanks to the R134a refrigerant.


  • Multi-function screen
  • Power consumption depending on the load
  • Up to 90% reduction in rated consumption
  • Automatic purge
  • Low voltage for driving
  • Modifiable screen from °C to °F
  • Option: alarm contact and 0 - 10V analog signal for dew point ratio
  • Refrigerant used R134a, for the total respect of the ozone layer
  • Compact design
