Page 5: Basic
1.3 Basic Compressed air contains contaminants such as water, oil and particles. Impurities need to be removed or their concentration reduced to an acceptable level according to the requirements of the application. The ISO 8573-1 standard specifies the purity / quality of the air for contaminants. The humidity (water vapor content) can be expressed in terms of Pressure Dew Point (PDP). -

Page 11: Refrigeration Air Dryer Operation
4 Refrigeration air dryer operation The refrigeration air dryer is designed to remove moisture from the input air to achieve the desired dew point at the exit. All refrigeration air dryers described above operate according to the same principle. The operation of the refrigeration air dryer can be divided into two main circuits: Air and refrigeration circuit. -
Page 12: Refrigeration Air Dryer Components
5 Refrigeration air dryer components 5.1 Compressor The compressor sucks the gaseous phase of the refrigerant from the evaporator (low pressure side) and compresses it to the condensation pressure (high pressure side). Built-in compressors are manufactured by leading manufacturers and are designed for applications where high compression ratios and high temperature differences are present. -
Page 13: Controller Rdc 3
5.4 Controller RDC 3 The controller can be started by holding SET + UP button for 3 seconds. For three phase dryers, it is recommended that the controller remains in OFF state for 2 hours before startup. At startup, the controller shows the time remaining until compressor starts by displaying t0 and remaining seconds. -
Page 14: Electric Scheme Rdc 3
5.4.1 Electric scheme RDC 3 The controller has 3 outputs (230 V), for compressor, fan and drain. The other outputs are for alarm. The alarm is triggered via opto triac, which can handle 600VAC/50mA. Controller can also be turned OFF/ON via In. Remote by changing the parameter 13 (Remote control) from 0 to 1. -

Page 18: Automatic Mechanical Condensate Drain
5.6. Automatic mechanical condensate drain Automatic mechanical condensate drain AOK 13PA has been developed for fully automatic discharging of condensate or any other non-aggressive fluid from compressed air system. The unit can be installed as external drain on any application specified below. Condensate accumulates in reservoir and when the level is high enough condensate is being discharged from the system without any air losses. -
Page 19: Capillary Tube
5.9 Capillary tube The capillary tube is located between the condenser and the evaporator and functions as a metering device for reducing the pressure of the refrigerant. The pressure reduction is a design-based function. The length and inner diameter of the capillary tube are precisely dimensioned, ensuring good performance in all designed conditions. -
Page 20: Storing

Page 23: Start-Up
10 Start-up 10.1 Before start-up Before start-up, check that the operating parameters correspond to the nominal values indicated on the data label of the dryer (frequency, air pressure, air temperature, ambient temperature, ...). This dryer has been fully tested, packaged and checked before shipping. Nevertheless, it may happen that it is damaged during transport. -
Page 24: Maintenance
12 Maintenance During the maintenance work on the refrigeration air dryer, turn it off and wait for at least 30 minutes for it to cool down. Some components can reach high temperature during operation. Avoid contact with these components until they completely cool down. Daily check that the dew point shown on the controller is appropriate. - Page 25 ● The dryer does not start. ● Dew point sensor incorrectly detects temperature - check if the sensor is fully inserted into the sleeve. ● The compressor does not work. ● Ambient temperature is too high, or ventilation is too low - ensure adequate ventilation.
