The Airpol refrigeration air dryer is an ideal component of a pneumatic installation which removes water and water vapour from compressed air and ensures drying at the pressure dew point temperature of +3ºC.
The pressure dew point defines the temperature to which compressed air can be cooled without condensation of the contained water.
The atmospheric air sucked in by the compressor contains water vapour and solid impurities. After compression, the exhaust air has a temperature about 10 degrees higher than the ambient temperature (screw compressor). As a result of the contact with ambient conditions and the resulting temperature difference, the air cools and condensate is precipitated from it, which can cause corrosion, accelerate wear and tear on pipelines and installed equipment and tools, and thus disrupt the production process. A perfect solution that can minimise the risk of these adverse effects is the use of a refrigeration air dryer together with compressed air filters. They allow to obtain air dried and free from impurities.

Reliable, economical and simple solution to avoid condensation and corrosion caused by it in systems.
Airpol OPA and OP series refrigeration air dryers use marginal amounts of energy to maintain the compressed air system in an optimum condition, effectively and reliably removing moisture and ensuring dry air in the system.
Incoming compressed air with an average temperature of +30ºC ÷ +45ºC is initially cooled in the air/air exchanger to a temperature of +14ºC ÷ +23ºC. Then, in the evaporator of the cooling cycle, the air is further cooled and reaches the set dew point temperature of +3ºC, which is necessary to condense the water vapour present in the compressed air cycle.
What are the benefits of compressed air drying?
• extended service life of connected pneumatic tools,
• improved process reliability,
• positive impact on the reliability of devices powered by compressed air,
• savings in the cost of inspection and servicing of machines,
• reducing the risk of corrosion of pneumatic systems,
• possibility of avoiding unexpected disruptions of production processes,
• limiting the amount of oil condensate that needs to be disposed of,
• environmental protection,
• assurance of obtaining a 4th class of compressed air quality in terms of water content according to ISO 8573-1.
Installation diagram of the refrigerated air dryer
Installation (A)
3 – prefilter (Q) and fine filter (P or S), 4 – by-pass and ball valves
Installation (A) is reccomended when constant compressor operation and constant air delivery is required.
Installation (B)
3 – prefilter (Q) and fine filter (P or S), 4 – by-pass and ball valves
Installation (B) is recommended when there is no constant compressed air intake, and disposable air demand is much higher or significantly lower than the nominal compressor capacity. Air receiver volume must be big enough to provide the required quantity of dried compressed air.
