Pneumatic Circuit

Hot and humid air entering this product is cooled down by the cooler. The moisture condensed at this time is separated by the drain separator and exhausted automatically. The pressure of the dry air is adjusted by the regulator, and oil mist and solid particles are separated by the micro mist separator with pre-filter and super mist separator. The temperature of the dry and high-purity air is adjusted by the heater, and the air is supplied to the outlet side.

*The type without filter is not applicable.

Refrigerant Circuit

The HFC gas contained in the refrigerant circuit is compressed by the compressor, and cooled and liquefied by the condenser. When passing through the capillary tube, the HFC gas is regulated and its temperature decreases. While passing through the cooler part, it evaporates rapidly, taking the heat from the compressed air, and is sucked in by the compressor. The capacity regulating valve opens when the compressed air has been cooled sufficiently, and prevents condensed water from being frozen by excessive cooling.

*1: ANR is the value at 20°C, atmospheric pressure and relative humidity 65%.
*2: About 10 minutes are required until the temperature becomes stable after setting the temperature.
*3: The upper limit of the settable outlet air temperature varies depending on the conditions even within the operating range. Be sure to read the selection document before selecting the models.
*4: The rated performance is the performance when the operation of each part is stable without fluctuations in operating conditions and power supply. If the air flow capacity is beyond its specified range or if the air flows intermittently, the outlet air temperature range or temperature stability may not be satisfied. (If this happens, install a purge line and flow the compressed air continuously.)
*5: When the outlet air temperature is set in the range of the ambient temperature ±5°C.
*6: Keep the voltage within -5 to +10% of the rated voltage. If there is voltage fluctuation, the outlet air temperature stability may decrease. So if highly accurate temperature adjustment is required, use a stable power supply to make the voltage fluctuation smaller.
*7: The specification changes depending on the cleanliness of the inlet side air. It may take time until the cleanliness of the filter outlet side air stabilizes immediately after start of operation. The filter performance only applies to the built-in type filter.
*8: 1 m in front of the product, 1 m in height, without load, stable conditions.

Condensed Water Calculation

Condensed water calculation chart

Condensed water calculation chart

How to calculate the amount of condensed water

Example: To obtain the amount of condensed water when the pressure is applied to air up to 0.7 MPa with an air compressor, then cooled down to 25°C, with an ambient temperature of 30°C and a relative humidity of 60%.

  • 1. Trace the arrow mark from point A at an ambient temperature of 30°C to obtain intersection B on the curved line for the relative humidity of 60%.
  • 2. Trace the arrow mark from intersection B to obtain intersection D on the pressure characteristic line for 0.7 MPa.
  • 3. Trace the arrow mark from intersection D to obtain intersection E.
  • 4. Intersection E is the dew point under pressure of 0.7 MPa with an ambient temperature of 30°C and a relative humidity of 60%. The value for E is 62°C.
  • 5. Trace intersection E upward, and trace from intersection D leftward to obtain intersection C.
  • 6. Intersection C is the amount of moisture included in the compressed air of 1 m3 at 0.7 MPa and a pressure dew point of 62°C. The amount of moisture is 18.2 g/m3.
  • 7. Trace the arrow mark, starting from F for a cooling temperature of 25°C (pressure dew point of 25°C) to obtain intersection G on the pressure characteristic line for 0.7 MPa.
  • 8. From intersection G, trace the arrow mark to obtain intersection H on the vertical axis.
  • 9. Intersection H is the amount of moisture included in the compressed air of 1 m3 at 0.7 MPa and a pressure dew point of 25°C. The amount of moisture is 3 g/m3.
  • 10. Therefore, the amount of condensed water is as follows:

(Per 1 m3) Amount of moisture at intersection C - amount of moisture at intersection H = amount of condensed water or 18.2 - 3 = 15.2 g/m3

Dew Point Conversion Chart

Dew point conversion chart

Dew point conversion chart

How to read the dew point conversion chart

(Example) To obtain the atmospheric pressure dew point at a pressure dew point of 10°C and a pressure of 0.7 MPa.

  • 1. Trace the arrow mark starting from point A at a pressure dew point of 10°C to obtain intersection B on the pressure characteristic line for 0.7 MPa.
  • 2. Trace the arrow mark starting from point B to obtain intersection C at the dew point under atmospheric pressure.
  • 3. Intersection C is the conversion value -17°C under the atmospheric pressure dew point.

Precautions

Avoid installing in the following locations

  • Avoid locations in direct contact with wind or rain and locations with high humidity. (Relative humidity 85% or more)
  • *Avoid exposure to direct sunlight.
  • *Avoid locations that contain large amounts of dust, corrosive gases, or flammable gases.
  • *Avoid locations with poor ventilation and high temperatures.
  • *Avoid locations where there is strong magnetic noise (strong electric field, strong magnetic field, or surge).
  • *Avoid locations or conditions where static electricity is discharged to the body.
  • *Avoid locations where the temperature rapidly changes.
  • *Avoid locations where the dryer is likely to be damaged by lightning.
  • *Avoid locations with an altitude of 2,000 m or higher. (This does not apply to storage and transportation.)
  • *Avoid locations where the dryer could draw in high-temperature air discharged from an air compressor or other dryer.
  • *Avoid locations subject to strong impact or vibration.
  • *Avoid conditions where an external force or weight that could deform the dryer is applied.
  • *Avoid locations where the drain could freeze.
  • *Avoid installation on machines for transportation, such as vehicles and ships.
  • *Avoid locations subject to sudden changes in pressure or flow rate.
