9.1 Place of installation
Note!
Ambient conditions!
In the event that the dryer is not installed under suitable ambient conditions, the ability of the device to con-
dense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and in a
loss of efficiency and performance of the dryer.
This in turn leads to overheated condenser fan motors, to malfunction of electric components and to a
breakdown of the dryer.
Do not install the dryer in an environment in which chemicals with a corrosive effect, explosive gases, toxic
gases, evaporation heat, high ambient temperatures or extreme dust and dirt can be found.
Minimum installation requirements
Choose an area which is clean and dry, free from dust and protected against atmospheric disturbances.
The load-bearing zone must be even, horizontal and able to bear the weight of the dryer.
Minimum ambient temperature +1°C.
Maximum ambient temperature 50°C.
Leave a free area of at least one metre in all directions of the dryer. This space is necessary to facilitate maintenance
works.
The dryer does not need bottom attachment. However, in installations in which the device is suspended, an attaching
part will be required for the suspended device.

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 RA 40 has a nominal capacity of 240 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
Factor (F1) = 1.05
Factor (F2) = 0.88
Factor (F3) = 0.70
Factor (F4) = 1.37
Every data element has a corresponding numerical factor, which, multiplied with the nominal capacity, is as follows:
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:
required nominal capacity
Min. air throughput = factor (F1) x factor (F2) x factor (F3) x factor (F4)
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
Factor (F1) = 1.05
Factor (F2) = 0.88
Factor (F3) = 0.70
Factor (F4) = 1.37
For the selection of the suitable dryer type, the required air flow must be divided by the correction factors of the pa-
rameters indicated above:
180
Min. air throughput = 1.05 x 0.88 x 0.70 x 1.37 = 203 m³/h
The suitable model is, therefore, DRYPOINT RA 40 (240 m³/h – nominal capacity).

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 neces-
sary. 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.

9.6 Electrical connections
Danger!
Supply voltage!
The connection to the electric mains should only be carried out by qualified skilled personnel and must
correspond to the legal provisions in force in your region.
Prior to connecting the device, please check the type plate to avoid exceeding the indicated values. The voltage toler-
ance is +/- 5%.
DRYPOINT RA 3-60 dryers are supplied with a VDE 16A standard power cord and safety plug (two-pole and earth
connection). DRYPOINT RA 80-160 devices have a junction box on the back plate.
Make sure that suitable fuses or circuit breakers in accordance with the indications on the type plate are available.
The wall socket must be equipped with a fault current circuit breaker (In=0,03A) which must be adjusted according to
the power consumption of the dryer (see nominal values on the type plate of the dryer). The cross-section of the power
supply cable must correspond to the power consumption of the dryer. In this respect, the ambient temperature, the
cable laying conditions, the length of the cables and the requirements of the local electricity supplier need to be con-
sidered.
Danger!
Supply voltage and missing earth connection!
Important: ensure that the plant is connected to earth.
Do not use plug adapters at the power plug.
Possible replacement of the power plug must only be carried out by a qualified electrician.
9.7 Condensate drain
Danger!
Compressed air and condensate under pressure!
The condensate is discharged at system pressure.
The drain pipe needs to be secured.
Never direct the condensate drain pipe at persons.
The dryer is delivered with an already integrated electronically level-controlled BEKOMAT condensate drain. Connect
the condensate drain with a collection system or container by properly screwing it on.
Do not connect the drain with pressure plants.
Do not discharge the condensate into the environment.
The condensate accumulating in the dryer contains oil particles which were released into the air by the
compressor.
Dispose of the condensate in accordance with the local provisions.
It is advisable to install a water-oil separator, to which the total amount of condensate from the compres-
sors, dryers, tanks, filters etc. is supplied.
We recommend ÖWAMAT oil-water separators for dispersed compressor condensate and BEKOSPLIT
emulsion-splitting plants for emulsified condensate.
