Installation type A is recommended when the compressor functions with reduced step switching and when the total
consumption corresponds to the throughput rate of the compressor.
Installation type B is recommended when the air consumption constantly varies, with peak values which considerably
exceed the throughput rate of the compressor. The storage capacity of the tank must be dimensioned in such a way
that a possible short-term high air demand (peak air consumption) can be compensated.
Note!
Contaminated intake air!
In the event that the intake air is strongly contaminated (ISO 8573.1 class 3.-3 or poorer quality), we
recommend the additional installation of a prefilter (e.g. CLEARPOINT F040), to avoid clogging of the
heat exchanger.

9.3 Correction factors
Correction factor for operating pressure modifications:
Air inlet pressure bar(g) 4 5 6 7 8 10 12 14 15 16
Factor (F1) 0,77 0,86 0,93 1,00 1,05 1,14 1,21 1,27 1,30 1,30
Correction factor for ambient temperature modifications (air-cooled):
Ambient temperature ºC 25 30 35 40 45 50
Factor (F2) 1,00 0,99 0,97 0,93 0,88 0,81
Correction factor for inlet air temperature modifications:
Air temperature ºC 25 30 35 40 45 50 55 60 65 70
Factor (F3) 1,27 1,12 1,00 0,88 0,78 0,70 0,62 0,55 0,49 0,43
Correction factor for dew point modifications:
Dew point ºC 3 5 7 10
Factor (F4) 1,00 1,09 1,19 1,37
Calculation of the air throughput:
Air throughput = nominal capacity x factor (F1) x factor (F2) x factor (F3) x factor (F4)
Example:
The R A 40 has a nom inal capac ity of 24 0 m³ / h . Which is the max. permissible flow through the dryer under
the following operating conditions?
Air inlet pressure = 8 bar(g)
Ambient temperature = 45°C
Air inlet temperature = 50°C
Pressure dew point = 10°C
Every data element has a corresponding numerical factor, which, multiplied with the nominal capacity, is as follows:
Factor (F1) = 1.05
Factor (F2) = 0.88
Factor (F3) = 0.70
Factor (F4) = 1.37
Air throughput = 240 x 1.05 x 0.88 x 0.70 x 1.37 = 212 m³/h
212 m³/h This is the maximum throughput rate for a dryer under these operating conditions.
Selection of a suitable dryer for a given task:
Min. air throughput =
Example:
With the following operating parameters:
Required nominal capacity = 180 m3/h
Air inlet pressure = 8 bar(g)
Ambient temperature = 45°C
Air inlet temperature = 50°C
Pressure dew point = 10°C
For the selection of the suitable dryer type, the required air flow must be divided by the correction factors of the parameters indicated above:
Min. air throughput =
The suitable model is, therefore, DRYPOINT RA 40 (240 m³/h – nominal capacity).
factor (F1) x factor (F2) x factor (F3) x factor (F4)
1.05 x 0.88 x 0.70 x 1.37
required nominal capacity
Factor (F1) = 1.05
Factor (F2) = 0.88
Factor (F3) = 0.70
Factor (F4) = 1.37
180
= 203 m³/h

9.4 Connection to the compressed-air system
Danger!
Compressed air!
All works must only be carried out by qualified skilled personnel.
Never work on compressed-air systems which are under pressure.
The operator or the user must ensure that the dryer is never operated with a pressure exceeding the
maximum pressure value indicated on the type plate.
Exceeding the maximum operating pressure can be dangerous for the operator but also for the device.
The air temperature and the air flow at the inlet of the dryer must lie within the limit values indicated on the type plate.
The connecting lines must be free from dust, iron rust, shards and other contaminations and correspond to the flow
rate of the dryer. Should air with a very high temperature be treated, the installation of an aftercooler may be necessary. For the implementation of maintenance works, the installation of a bypass system is recommended, as is shown
in the following illustration.

The dryer was designed in such a manner that vibrations that may occur during operation are limited. Therefore, it is
advisable to employ connecting lines (flexible hoses, vibration-inhibiting fittings etc.) which protect the dryer against
possible vibrations in the pipework.
Note:
During the piping of the dryer, the inlet and outlet connections need to be fixed in position, as is
shown in the illustration.
Non-observance will cause damage.

9.5 Connection to the cooling-water network (water-cooled)
Danger!
Compressed air and unqualified personnel!
All works must only be carried out by qualified skilled personnel.
Never work on compressed-air systems which are under pressure.
The user must ensure that the dryer is never operated with a pressure exceeding the nominal values.
Possible overpressure can be dangerous for the operator but also for the device.
The temperature and the amount of cooling water need to correspond to the limit values indicated on the type plate.
The cross-section of the connecting lines which should preferably be flexible, must be free from dust, iron rust, shards
and other contaminations. We recommend employing connecting lines (flexible hoses, vibration-inhibiting fittings etc.)
which protect the dryer against possible vibrations in the pipework.
