Structure Principle Diagram (Air/Refrigerant Circuit)
Humid, hot air coming into the air dryer is cooled down by a cooler re-heater (heat exchanger). Water condensed at this time is removed from the air by a drain separator (auto drain) and drained out automatically. Air separated from the water is heated by a cooler re-heater (heat exchanger) to approximately ambient temperature to obtain the dried air, which goes through to the outlet side.

*1: Indicates the air flow capacity under ANR (atmospheric pressure 68°F (20°C), relative humidity 65%).
*2: Indicates the air flow capacity for each outlet pressure dew point.
*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.
*7: When a short-term interruption of the power supply (including momentary interruption) occurs in this equipment, the restarting of normal operations may require some time or may be impossible due to the operation of protective devices even after the supply of power returns.
