Construction (Air/Refrigerant Circuit) IDU22E, IDU37E, IDU55E, IDU75E Humid, hot air coming into the air dryer will be cooled down by a heat exchanger. Water condensed at this time will be removed from the air by a drain separator and drained out automatically. Air separated from the water will be heated by a heat exchanger to obtain the dried air, which goes through to the outlet side. Note 1) Air flow capacity under the standard condition (ANR) [atmospheric pressure 20°C, relative humidity 65%] Note 2) Air flow capacity converted by the compressor intake condition [atmospheric pressure 32°C, relative humidity 75%] Note 3) The operation range does not guarantee the use with normal air flow capacity. Note 4) Select the air dryer model according to “Model Selection” (pages 26, 27) for models beyond the rated specifications. Note 5) These values are reference values under rated conditions, and are not guaranteed. Do not use these values for the thermal set values, etc. Note 6) Product other than the option R is not equipped with a circuit breaker. Please purchase an appropriate circuit breaker separately. Note 7) The part number for the auto drain components only excluding the body part. Body part replacement is not possible.
