Working Conditions
- Max Ambient temperature +38°C
- Minimum ambient temperature +1°C
- Maximum inlet air temperature +45°C
- Nominal inlet air pressure 7 Bar
- Maximum inlet air pressure: 16 Bar
- Out let air pressure drop P: 0.2 Bar
- Maximum electric power:
- Noise level < 70dbA
- At nominal compressed air inlet
pressure 7 bar, ambient temp 38°C & inlet temperature of 45°C
conditions - achived pressure Dew point +3°C / ADP - 22°C
- Max inlet air temp to the dryer +45°C
and above we recommend after cooler to reduce the inlet air
temperature.

Puronics System Refrigerant Dryers
Functioning principle of the dryer.
The dryers of the RD series are
basically made by two different circuits. A compressed Air circuit
divided into two, heat exchangers and a refrigerating circuit. The
hot and humid input compressed air passes through the air to air
exchanger and then reaches the evaporator (air-freon exchanger),
where it is cooled by the refrigerating circuit until it reaches the
present dew point, thus condensing the humidity it contains. IN the
moisture separator the condensed humidity is then separated and
removed by auto drain.
The advantages of such a system are
essentialy two, first of all the air input is pre - cooled , so the
refrigerating system can be sized in order to guarantee a more
limited thermal jump, with an energy saving of about 40-50%, and
secondly no cold air is conveyed through the compressed air line,
thus preventing overall the formation of condensate on the external
surface of the piping.
