Product Description
Refrigerated air dryer with improved corrosion resistance due to the use of a stainless-steel heat exchanger.
[Features]
· 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.
· Air flow capacity increased up to 40%.
· Power consumption reduced up to 40%.
· Energy-saving design.
· Exhaust heat reduced by 25%, controlling increases in ambient temperature (air-cooled specification) and reducing heat discharging water amount (water-cooled specification).
· Inlet air temperature: 35°C (22E, 37E) / 40°C (55E, 75E).
· Outlet air pressure dew point: 10°C.

*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.
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 drained out automatically by the auto drain. Air separated from the water is heated by a cooler re-heater (heat exchanger) to obtain the dried air, which goes through to the outlet side.
