• A polyurethane tube of 10mm external diameter is attached to the drain tube. The outlet end of the tube is
released to atmosphere. And let drain flow through the tube into a scupper and so on.

• Using the pressure of the compressed air, drain will be discharged periodically. Fix the outlet end of the tube so
as not to swing during discharge.

• Prevent the drain tube from riser piping.

• Prevent the drain tube from being folded or flatted. Since the drain tube is coming from the bottom of the body,

be careful to avoid the body from stomping over the tube during installation.

Warning

During drain work, follow the procedure that you define to keep the safety of worker (ex. Put on
protective glass, apron, and gloves).

In case that oil gets mixed in the wasted water that is discharged from the auto drain, the waste liquid treatment

3 - 1

Air Dryer (IDF1E-10～IDF15E-10/20) 3 Operation / Shutdown

Caution

Avoid frequent On/Off operation, which can cause troubles.
The auto drain used for the product has a structre that closes the valve with air pressure hig her

than 0.15MPa. Therefore, until the pressure increase, air will be emitted form the drain outlet at
the begining of opening the IN side valve. Keep in mind that sometime the pressure cannot
increase enough with air compressor that has low dischage flow rate.

3-3 Shutdown

• Turn off the illuminated switch.

• The lamp will go out and then, the operation will be stopped. Depending on the condition of operation, hot air

continues to be emitted from the ventilation grille by the cooling fan for a while after turning off the switch,
which is not an abnormality but a process for safety shutdown.

3-4 Cautions about restart

• One must wait for at least 3 minutes before restarting air dryer after it has been shut down. Failure to do this
may cause safety devices to trip due to over load.

3-5 Check points before restart

Check following points before you start operation. If any abnormalities occur, immediately stop the operation. Turn off the
illuminated switch of the product and then the breaker to the power supply.

• There is no leakage of compressed air.

• Compressed air pressure, temperature, flow rate, and ambient temperature meet the specifications.

• Drain is being discharged from the drain tube.

• The pointer of evaporation thermometer is indicating in the green zone.

• There are no abnormal sound, vibration, or smelling.

3-6 Precautions for long-term non-operation

• If the product will not be operated for more than 24 hours, for example at the weekend, turn off the ILS (switch
with lamp) or power supply, for energy saving and safety. It is also recommended to r elease the pressure
inside the compressed air piping and this air dryer.

6-4 Compressed Air and Refrigerant Circu it / Operation Principles

y IDF１E

Compressed Air Circuit

Humid hot air entering air dryer is cooled in

the cooler. At this time, the condensed

moisture is separated from the air by the

drain separator and automatically

discharged.The dried clean air is heated by

the reheater untill it gets about the same

temperature as that of ambient air. It is then

discharged from air dryer outlet.

Refrigerant Circuit

The Fluorocarbon charged in the

refrigerant circuit is compressed by the

compressor and cooled by the condenser

to become liquid. Then, going through the

capillary tube, it is decreased the pressure

to reach a low temperature. Passing

through the cooler part, it

draws heat from

compressed air and intensely boils. Finally

it is inhaled into the compressor again. The

capacity control valve opens to prevent

dew drops from freezing when

compressed air is cooled enough.
