Refrigerated Air Dryer, Refrigerant R134a (HFC) High Temperature Air Inlet, IDU□E Series (IDU3E-20-L)

SMC

Refrigerated air dryer that protects pneumatic equipment from moisture.
[Features]
· Removes the vapor from the moist compressed air delivered by the compressor, and prevents it from causing the pneumatic equipment to fail.
· Improved corrosion resistance with the use of stainless-steel heat exchanger.
· High-temperature intake air type.
· IDU-□E-10: Single-phase: 100 V AC (50 Hz), 100/110 V AC (60 Hz).
· IDU-□E-20: Single-phase: 200 V AC (50 Hz), 200/220 V AC (60 Hz).
· IDU-□E-23: Single-phase 230 V AC (50 Hz).

*1: Indicates the air flow capacity under the standard condition (ANR) (atmospheric pressure 20°C, relative humidity 65%).
*2: Indicates the air flow capacity converted by the compressor intake condition (atmospheric pressure 32°C, relative humidity 75%).
*3: The operating range does not guarantee use at rated air flow capacity.
*4: If the operating conditions differ from the rating, select the model referring to "Model Selection" in the manufacturer's catalog.
*5: Refer to "How to Order" in the manufacturer's catalog when selecting the power supply voltage.
*6: These are reference values under the rated conditions and are not guaranteed. Do not use these as thermal setting values, etc.
*7: For models IDU8E or larger, the energy-saving function is provided by adding an aftercooler as a cooling system.
*8: Products without option R do not come with a circuit breaker. Purchase a circuit breaker separately.

Structure Principle Diagram (Air/Refrigerant Circuit)

Humid, hot air coming into the air dryer is cooled down by a heat exchanger. Water condensed at this time is removed from the air by a drain separator and drained out automatically. Air separated from the water is heated again by the heat exchanger to obtain the dried air, which goes through to the outlet side.
For models IDU8E to 15E1, the humid, hot air introduced to the air dryer is cooled down by an aftercooler before being cooled down by the heat exchanger.
