How to Calculate Outlet Air Temperature

The outlet air temperature can be calculated by the inlet air temperature, ambient temperature and air flow capacity using the following procedure.

(Example) Inlet air temperature: 100°C, Ambient temperature: 20°C, Air flow capacity: 2,000 L/min (ANR), Air pressure:
0.7 MPa, Model: HAA22-14

Correction factor by ambient temperature

1. Use an outlet air temperature of 38.5°C from the Outlet Air Temperature table. In this case, use correction factor line A.
2. Next, use the correction factor by ambient temperature chart to obtain a correction factor of 1.35 at the ambient temperature of 20°C on line A.
3. Divide 38.5°C (from step 1) by 1.35 (from step 2) to obtain the outlet air temperature. Outlet air temperature = 38.5 ÷ 1.35 = 28.5°C

	(B)	5,700	35	40	43
	(C)	7,000	36	42	45

Conditions:

Air pressure 0.7 MPa, ambient temperature 32°C.
An inlet air temperature of 50°C is saturated air. At 70°C or more, it is humid air with a dew point of 67°C.

Precautions

Caution on Design

Caution

1. Do not obstruct the aftercooler's vent inlet and outlet, and be sure to install the aftercooler more than 20 cm away from the walls and other equipment.
2. Install the aftercooler in a location that facilitates maintenance and inspection.
3. Install the aftercooler in a location with minimal vibrations.
4. Because the surrounding temperature increases due to the exhaust heat from the aftercooler, ventilate the area with an exhaust fan, etc.
5. The air-cooled type aftercooler cannot be used in a location where the temperature exceeds 50°C. To use in such a location, use a water-cooled type aftercooler instead.
6. The maximum allowable temperature of the inlet air is 100°C.
If the inlet air exceeds this temperature, select an appropriate water-cooled type aftercooler.
7. Prevent fins from becoming clogged. Do not use this aftercooler in an area that has viscous dust (electrostatic paint powder, oily particles, etc.). If it must be used under such conditions due to unavoidable circumstances, please contact the manufacturer support center beforehand.

Mounting

Caution

1. Do not interchange the connections to the compressed air inlet and the compressed air outlet. When tightening the air inlet and outlet piping, make sure to use a pipe wrench to hold the inlet and outlet nozzles of the product.
2. Connect a drain pipe because drainage is created when the compressed air is cooled.
3. The drain pipe must have a minimum pipe bore of 10 mm and a maximum length of 5 m (when installing an optional auto-drain).

Maintenance

If the aftercooler is equipped with an auto drain, the following mounting frame is necessary. Mounting frame (Option: Refer to p. 11 Accessories)

Caution

1. Inspect the cooler at least once a week, and clean it to prevent it from becoming obstructed.
2. Discharge the drainage on a regular basis in accordance with the amount of drainage that is created. (The optional auto drain is recommended for automatic discharge.)
