Product Description

Large refrigerated air dryer with energy-saving design.
[Features]
· Refrigerated air dryer that protects pneumatic equipment from moisture.
· Removes the vapor from the moist compressed air delivered by the compressor, and prevents it from causing the pneumatic equipment to fail.
· Voltage (IDF190D-3): Three-phase: 200 V AC (50 Hz) / 200/220 V AC (60 Hz).
· Voltage (IDF190D-9): Three-phase different voltage (built-in transformer).
· Power supply voltage: 220 V / 380 V / 400 V / 415 V / 440 V.

*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: Products without option R do not come with a circuit breaker. Purchase a circuit breaker separately.
*8: JIS 10K FF is used as a flange.

Structure Principle Diagram (Air/Refrigerant Circuit)

High temperature humid air from the air compressor passes through the air re-heater (1) and is pre-cooled by dehumidified cool air. Then it is cooled to the specified temperature by the air cooler (2) using the evaporation heat of the refrigerant.
At this time, the oil mist and moisture generated by condensation are automatically exhausted by the auto drain (3).
The cooled and dehumidified air goes back to the air re-heater (1), and heat is exchanged with hot air that flows into the air re-heater. It is supplied as dry warm air without "sweating" in the piping system.
