*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: These are reference values under the rated conditions and are not guaranteed. Do not use these as thermal setting values, etc.
*6: Products without option R do not come with a circuit breaker. Purchase a circuit breaker separately.

Structure Principle Diagram (Air/Refrigerant Circuit)

Structure Principle Diagram: IDU22E/IDU37E/IDU55E/IDU75E (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.
