How to calculate the amount of condensed water

Example) To obtain the amount of condensed water when the inlet air of a compressor is pressurized to 0.7 MPa then cooled down to 25

°

C.

Given an ambient temperature of 30

°

C and a relative humidity of 60%.

1. Trace the arrow mark from point A of ambient temperature 30

°

C to obtain the intersection B on the curved line for the relative humidity of 60%.

2. Trace the arrow mark from the intersection B to obtain the intersection D on the curved line for the

0.7 MPa pressure characteristics.

3. Trace the intersection D to obtain the intersection

E.

4. The intersection E is the pressure dew point at 0.7

MPa with an ambient temperature of 30

°

C and a relative humidity of 60%. The value for E is at

62

°

C.

5. Trace the intersection E upward to D and leftward to obtain the intersection C on the vertical line.

6. The intersection C is the amount of water which is included in the compressed air 1 m 3 at 0.7 MPa, a pressure dew point of 62

°

C. The amount of water is 18.2 g/m 3 .

7. Trace the arrow mark from F (cooling temperature

25

°

C (pressure dew point 25

°

C)) to obtain the intersection G on the pressure characteristic line for

0.7 MPa.

8. From the intersection G, trace the arrow mark to obtain the intersection H on the vertical line.

9. The intersection H is the amount of water which is included in the compressed air 1 m 3 at 0.7 MPa, pressure dew point of 25

°

C. The amount of water is 3.0 g/m 3 .

10. Therefore, the amount of condensed water is as following. (per 1 m 3 )

The amount of water at the intersection C

– the amount of water at the intersection H

= the amount of condensed water

18.2 – 3.0 = 15.2 g/m 3

Specific Product Precautions 1

Be sure to read this before handling. For Air Preparation Equipment Precautions, refer to “Precautions for Handling Pneumatic Devices” (M-03-E3A).

Installation

Caution

• Avoid locations where the air dryer will be in direct contact with wind and rain. (Places where relative humidity is greater than

85%)

• Avoid exposure to direct sunlight.

• Avoid locations that contain much dust, corrosive gases, or flammable gases. Failure due to corrosion is not covered under warranty. However, when the risk of corrosion is high, select

“Option C” (copper tubing with anti-corrosive treatment).

• Avoid locations of poor ventilation and high temperature.

• Too close to a wall etc. Leave sufficient room between the dryer and the wall according to the “Maintenance space” in the operation manual.

• Avoid locations where a dryer could draw in high temperature air that is discharged from an air compressor or other dryer.

Air Piping

Caution

• Be careful to avoid an error in connecting the air piping at the compressed air inlet (IN) and outlet (OUT).

• Install by-pass piping since it is needed for maintenance.

IDFA3E

Compressed air inlet Compressed air outlet

Valve closed

Valve open

IDFA4E to 15E

The air exhaust should not flow into the neighboring equipment. (Top side)

• Avoid locations subjected to vibration.

• Avoid possible locations where the drain can freeze.

• Use the air dryer with an ambient temperature lower than 40

°

C.

• Avoid installation on machines for transporting, such as trucks, ships, etc.

Compressed air inlet Compressed air outlet

Valve closed

Drain Tube

Caution

• A polyurethane tube is attached as a drain tube for the IDFA3E to 37E. Use this tube to discharge drainage.

• Do not use the drain tube in an upward direction. Do not bend or crush the drain tube. (Operation of the auto drain will stop water vapor from discharging through the air outlet.)

IDFA22E, 37E

Power Supply

Caution

• Connect the power supply to the terminal block.

• Install a suitable circuit breaker applicable for the specific model.

• The voltage fluctuation should be maintained within

±

10% of the rated voltage.

Air Piping

Caution

IDFA55E, 75E

Compressed air outlet Compressed air inlet

Auto Drain

Caution

The auto drain may not function properly, depending on the quality of the compressed air. Check the operation once a day.

Valve closed

Valve open

Cleaning of Ventilation Area

Caution

Remove dust from the ventilation area once a month using a vacuum cleaner or an air blow nozzle.

• When tightening piping at the air inlet/outlet tube, the hexagonal parts of the port on the air dryer side or piping should be held firmly with a spanner or adjustable angle wrench.

• Variations in operating conditions may cause condensation to form at the surface of the outlet piping. Apply thermal insulation around the piping to prevent condensation from forming.

• Vibration resulting from the compressor should not be transmitted through air piping to the air dryer.

• Do not allow the weight of the piping to lie directly on the air dryer.

Time Delay for Restarting

Caution

Allow at least three minutes before restarting the dryer. If the air dryer is restarted within three minutes after being stopped, the protection circuit will be activated, operating light turns off and the dryer will not be activated.

Protection Circuit

Caution

When the air dryer is operated under the following stated conditions, a protection circuit is activated, the light turns off and operation stops.

• When the compressed air temperature is too high.

• When the compressed air flow rate is too high.

• When the ambient temperature is too high. (40

°

C or higher)

• When the fluctuation of the power supply is beyond the rated voltage

±

10%.

• When the dryer is drawing in high temperature air that is discharged from an air compressor or other dryer.

• The ventilation port is obstructed by a wall or clogged with dust.

Compressor Air Delivery

Caution

Use an air compressor with an air delivery of 100 l /min or larger with the IDFA3E to 75E series.

Since the auto drain of the IDFA3E to 75E is designed in such a way that the valve remains open unless the air pressure rises to

0.15 MPa or higher, air will blow out from the drain discharge port at the time of air compressor start-up until the pressure increases. Therefore, if an air compressor has a small air delivery, the pressure may not be sufficient.
