Humid hot air entering the air dryer is cooled in the aftercooler (air-cooling
style) and then further cooled by the cooler.
At this time, the condensed moisture is separated from the air by the drain
separator and automatically discharged. (IDU3D uses hot refrigerant vapor for
reheating.)
The dried clean air is heated by the hot air that has entered the dryer. It is then
discharged from air dryer outlet.

air outlet
Aftercooler
Fan motor
Evaporation
thermometer
Outlet air
pressure gauge
Humid hot air entering the air dryer is cooled in the after-cooler.
It then enters the reheater to creat an initial condensation with
cooled and dehumidified air. The hot air is cooled further and
dehumidified inside the cooler as heat is transferred to the
refrigerant. The water vapor condensed by the cooling process is
cooled and discharged automatically through the auto drain.
Cool air is then heated again inside the reheater (heat is
transferred from incoming hot air), before leaving the air dryer.

Hot humid air entering the reheater is precooled by
dehumidified cool air. (The hot air is cooled further
and dehumidified inside the cooler as heat is
transferred to the refrigerant. The water condensed
by the cooling process is collected and discharged
automatically by the auto drain.) Finally, the cool
dehumidified air is heated in the reheater by hot inlet
air and discharged in a dry state.

High temperature humid air is cooled in the reheater . Then it is further cooled
to a specified temperature using the evaporation heat in the air cooler . The oil
mist and moisture occurring due to condensation is exhausted through the auto
drain . Cooled and dehumidified air is returned to the air reheater
and heat
is transferred from the incoming high temperature air. It is then exhausted out of
the air dryer as dry air.

The power supply transformer can be integrated with an air dryer. It is used
when a refrigerated air dryer is using a non-standard voltage specification.
The power supply transformer for IDF120D to 240D is installed inside of the
air dryer. Therefore, external dimensions are the same as the standard
product.

Air temperature (Pressure dew point) °C
[Example] If air at 30°C and 60% humidity is pressurized to 0.7MPa, the dew point of the air will be 62°C. (
) If this is cooled to 25°C, the amount of
condensed water generated will be 15.2g/m³. (
) Therefore, with an air flow rate of 3m³/min (22kW equivalent compressor), the amount of condensed
water per unit of time is 15.2 x 3 x 60 = 2736g/h.

IDU/IDF
Air Preparation Equipment Precautions 1
Series
Be sure to read before handling.
Selection
Precautions on Design
Employ a safe design so that the following type
of unexpected conditions will not occur.
Caution
1. Do not allow flow greater than the rated flow
rate.
Warning
1. Design so that high temperature compressed
air does not flow to pneumatic equipment.
In case of cooling equipment failure (stoppage of cooling water
in water cooled type after cooler, stoppage of fan motor in air
cooled type after cooler, etc.) on the air supply side, high temperature compressed air can flow downstream and cause damage or malfunction of downstream equipment.
2. Use a design that allows for stoppage of the
compressed air supply.
Compressed air flow may be stopped by freezing of a refrigerated air dryer or malfunction of the switching valve (heatless dryer).
Caution
If the flow exceeds the rated flow rate even momentarily, this
can cause drainage and oil to be sprayed downstream or cause
damage, etc.
2. The product cannot be used with low pressure air (blowers).
Operating below the minimum operating pressure can cause reduced performance and malfunction. If this type of use is unavoidable, contact SMC in advance.
Mounting
Caution
1. Confirm the mounting orientation.
1. Use a design that prevents reverse pressure
and back flow.
Reverse pressure and back flow can cause equipment damage
or malfunction, etc.
Give attention to safety measures, including handling procedures.
Selection
Since the mounting orientation is different for each piece of
equipment, this should be confirmed either in this catalog or in
the instruction manual. Mounting in a tilted orientation can
cause faulty drainage discharge, auto drain malfunction and
damage in some types of equipment.
2. Ensure suffient maintenance space.
When installing and mounting, be sure to allow the space required for maintenance and inspections. Confirm the necessary
maintenance space in the instruction manual for each piece of
equipment.
Warning
1. When selecting equipment, first adequately
confirm the purpose for which it will be used,
the required specifications and the operating
conditions (pressure, flow rate, temperature,
environment), etc. Then select equipment
from the latest catalogs without exceeding
the specification ranges. Contact SMC in advance regarding any questions.
2. Do not use for caisson shields, breathing,
medical treatment or for blowing of medicine
or food products which will enter the human
body.
This cleaning equipment is exclusively for use with industrial
compressed air, and should not be used for other applications.
If other application is unavoidable, give attention to safety
measures and contact SMC in advance.
3. This product cannot be used on board vehicles or vessels.
This product cannot be used on board vehicles, vessels or other transportation devices, because vibration will cause damage.
If this type of use is unavoidable, contact SMC in advance.
27
Piping
Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and
other debris from inside the pipe.
2. Wrapping of pipe tape
When screwing together pipes and fittings, etc., be certain that
chips from the pipe threads and sealing material do not get inside the piping.
Furthermore, when pipe tape is used, leave 1.5 to 2 thread
ridges exposed at the end of the threads.
3. Implement measures to prevent drainage
from collecting inside piping.
Drains should be installed in the lower sections of piping that
rises, or piping should be designed with a slight taper provided
along the direction of flow so that drainage will not accumulate.
4. Confirm IN and Out ports.
When piping is being installed, take care to prevent incorrect
connection of the water and air sides, or the IN and OUT ports.

Be sure to read before handling.
Maintenance
Air Supply
Warning
Warning
1. Do not use with fluids other than compressed
air.
1. If an abnormality occurs, stop the compressed air.
Cleaning equipment is designed exclusively for use with compressed air. Contact SMC in advance if a fluid other than compressed air is to be used.
If abnormalities such as smoke, unusual odor or unusual noise
occur, stop the inflow of compressed air, as this may indicate a
fire.
2. Do not use compressed air which contains
chemicals, organic solvents or corrosive gases.
2. When performing inspections, set the compressed air pressure at zero.
Do not use compressed air containing chemicals, organic solvents, salt or corrosive gases, as this can cause damage
and/or malfunction, etc.
3. Use within the operating pressure range.
The operating pressure range is determined by the equipment
being used. Operation beyond this range can cause damage,
failure or malfunction.
Operating Environment
Warning
1. Do not use in the following environments, as
this can cause failure.
1. Locations with an atmosphere of corrosive gases, organic solvents or chemical solutions, or where there may be contact
with these.
2. Locations where there is contact with sea spray, water or
steam.
3. Locations which receive direct sunlight. (Sunlight should be
blocked to prevent deterioration of resin from ultra violet rays,
and over heating, etc.)
4. Locations near heat sources with poor ventilation. (Heat sources should be blocked off, because radiated heat may cause
damage due to softening of materials.)
5. Locations with impacts or vibration. (Check the specifications
for each series.)
6. Locations with high moisture and dust. (Contact SMC in advance.)
When the compressed air side is to be disassembled for auto
drain inspection, separator element replacement or film module
replacement, etc., confirm that the pressure is at zero before
proceeding.
Caution
1. Do not place heavy objects on the unit or use
it as a step.
The equipment may be deformed or damaged, and if balance is
lost, falling may cause injury.
2. Discharge drainage regularly.
Accumulation of drainage in equipment, piping or other areas
can cause malfunction of the equipment or unexpected trouble
due to splash over into the downstream side, etc. Therefore, the
amount of drainage and the operation of auto drains should be
checked every day.
2. Adhere to the fluid and ambient temperature
ranges.
The fluid and ambient temperatures are determined by the
equipment being used. Operation outside of the prescribed
range can cause damage, failure or malfunction, etc.

Specific Product Precautions 2
Air Preparation Equipment Precautions
Refer to pages 26 through 28 for safety instructions and cleaning equipment precautions.
Protection Circuit
Time Delay for Restarting
Caution
Caution
When the air dryer is operated under the following conditions, the
protection circuit is activated, the light goes off and operation
stops.
• When compressed air
temperature is too high
• When compressed air flow
rate is too high
• When ambient temperature
is too high (40°C or higher)
• When power supply is
beyond rated voltage by
±10%
• When ventilation port is obstructed by a wall or clogged with dust
Compressor Air Delivery
Allow at least three minutes
before restarting the dryer. If
the air dryer is restarted within
three minutes after being
stopped, the protection circuit
will be activated, the operating
light goes off and the dryer will
not be activated.
Please wait
three minutes!
Crank Case Heater
Caution
Caution
Use an air compressor of 100 l/min or greater air delivery with
IDF2D to 4D/IDU3D, 4D, and 300 l/min or greater air delivery
with IDF6D to 75C/IDU6D to 75C.
A crank case heater is installed on IDF370B. Energize the crank
case heater 12 hours prior to operation of the dryer to prevent
trouble occurring in the refrigerant compressor.
Since the auto drain of IDF2D to 75C/IDU3D to 75C is designed in
such a way that the valve remains open unless the air pressure
rises to 0.15MPa or higher, air will blow out from the drain
discharge port when the air compressor starts up until the pressure
increases. Therefore, if an air compressor has a low air delivery,
the pressure may not be sufficient.
Auto Drain
Caution
The auto drain may not function properly, depending on the quality
of compressed air. Check its operation once a day.
Cleaning of Ventilation Area
Caution
Remove dust from the ventilation area once a month using a
vacuum cleaner or an air blow nozzle.
