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.

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 nom inal 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:
3
 Required nominal capacity = 180 m /h
 Air inlet pressure = 8 bar(g)
 Factor (F1) = 1.05
 Factor (F2) = 0.88
 Ambient temperature = 45°C
 Factor (F3) = 0.70
 Air inlet temperature = 50°C
 Factor (F4) = 1.37
 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:
180
Min. air throughput =
= 203 m³/h
1.05 x 0.88 x 0.70 x 1.37
The suitable model is, therefore, DRYPOINT RA 40 (240 m³/h – nominal capacity).

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.

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 tolerance 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 considered.
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 compressors, dryers, tanks, filters etc. is supplied.
We recommend ÖWAMAT oil-water separators for dispersed compressor condensate and BEKOSPLIT
emulsion-splitting plants for emulsified condensate.

12.2 Functional description
Operating principle – All dryer models described in this manual function according to the same principle. The hot and
moisture-loaded air is led into an air/air heat exchanger. Afterwards, the air flows through an evaporator, which is also
known as an air/refrigerant heat exchanger. The air temperature is reduced to approximately 2°C, so that water vapour
condenses to liquid. The continuously accumulating condensate is collected in the separator to be discharged via the
condensate drain. Subsequently, the cold and dry air is led through the air/air heat exchanger, so that it is reheated to
up to 8°C below the inlet temperature when leaving the dryer.
Refrigeration cycle – The refrigerant is conducted through the compressor and reaches a condenser under high pressure. There, cooling-down takes place, making the refrigerant condense to a liquid state which is under high pressure.
The liquid is pressed through a capillary tube where the resulting pressure drop ensures that the refrigerant evaporates
at a defined temperature. The liquid refrigerant which is under low pressure is led into the heat exchanger, where it expands. The cold resulting from the expansion serves to cool down the compressed air in the heat exchanger. During this
process, the refrigerant evaporates. The low-pressure gas is resupplied to the compressor, where it is compressed
again. It then re-enters the cycle. In phases of a reduced compressed-air load, the excess refrigerant is resupplied
automatically to the compressor via the hot gas bypass valve.

Technical description
12.5 Refrigerating compressor
The gas from the evaporator (low-pressure side) is compressed to condensation pressure (high-pressure side). The
employed refrigerating compressors are constructed by leading manufacturers and are designed for applications in
which high compression rates are required and where strong temperature fluctuations exist.
The hermetically closed construction is absolutely gastight and guarantees a high energy yield and a long service life.
Acoustical emissions and vibrations are reduced by damping springs. The induced refrigerant gas cools the electric
motor. The integrated safeguard protects the compressor against overheating and excess current. The protection is
automatically set back as soon as the nominal conditions are reached again.
12.6 Condenser (air-cooled)
The condenser is the component in which the gas coming from the compressor is cooled down, condensed and liquefied. From the mechanical point of view, the condenser consists of a zigzag copper pipe (through which gas flows)
which is sheathed by an aluminium lamellae package.
Cooling-down takes place in the lamellae package through the air flow which is generated by a high-performance fan.
Under no circumstances must the temperature of the ambient air exceed the nominal values. It is also important that
the condenser unit is kept free from dust and other impurities.
12.7 Condenser (water-cooled)
The condenser is the component in which the gas coming from the compressor is cooled-down, condensed and liquefied.
The water inlet temperature must not exceed the nominal values. Likewise, a correct flow must be ensured. The water
entering the condenser must be free from impurities.
12.8 Cooling-water controller
The cooling-water controller serves to keep the condensation pressure or the condensation temperature constant during water cooling. Via a capillary tube, the valve registers the pressure in the condenser and adjusts the water flow
correspondingly. When the dryer is switched off, the valve automatically blocks the cooling-water flow.
Note!
The cooling-water controller is a control element.
Blocking of the water cycle through the cooling-water controller cannot serve as a safety shut-off measure
during maintenance measures at the system.
Setting
The cooling-water controller is preset to a value during the test phase at the manufacturer, with which at
least 90% of the applications can be covered. However, it is possible that extreme employment conditions
of the dryer require a more precise calibration.
During the start-up, certified skilled personnel should verify the condensation pressure and temperature
and adjust the valve accordingly, where required.
To increase the condensation temperature, turn the adjusting screw anticlockwise; to reduce it, turn it
clockwise. Adjust the valve in such a manner that a condensation temperature of 42 to 45 °C is ensured.

Technical description
12.9 Filter dryer
Despite controlled vacuuming, traces of moisture can accumulate in the refrigeration cycle. The filter dryer serves to
absorb this moisture and to bond it.
12.10 Capillary tube
The capillary tube is a copper tube with a reduced diameter which is located between the condenser and the evaporator, serving as a restrictor to reduce the pressure of the refrigerant. The pressure reduction serves to reach an optimum temperature inside of the evaporator. The lower the outlet pressure at the capillary tube, the lower the evaporation temperature.
The length and the inner diameter of the capillary tube are exactly dimensioned to ensure the performance of the
dryer. Settings or maintenance works are not required.
12.11 Aluminium heat exchanger
In the heat exchanger module, the air/air heat exchanger, the air/refrigerant heat exchanger, and the demister in the
form of a condensate separator are accommodated. The compressed-air reverse current in the air/air heat exchanger
guarantees maximum heat transfer. The large cross-section of the flow passage in the heat exchanger module causes
low flow rates. Together with the gas flow in a reverse current, the generous dimensions of the air/refrigerant heat
exchanger allow full evaporation of the refrigerant. This prevents moisture from entering the refrigerating compressor.
The high-performance condensate separator is inside of the heat exchanger module. Maintenance is not necessary
and the coalescence effect aims to achieve a high degree of moisture separation.
12.12 Hot gas bypass valve
At partial load, the valve directly returns a part of the hot gas to the suction line of the refrigerating compressor. The
evaporation temperature/pressure remain constant at approximately +2 °C. This injection prevents an ice formation in
the evaporator of the dryer under every load situation.
SETTING
The hot gas bypass valve is adjusted in the course of the production test
phase. Normally, no setting is required. Should an adjustment nevertheless be necessary, it should be carried out by certified skilled personnel.

Via a digital thermometer with an alphanumeric display, the DMC14 electronics indicate the dew point which is measured by the sensor in the evaporator.
The
LED indicates possible alarm situations, for example:
if the dew point is too high;
if the dew point is too low;
if the sensor is defective.
In the event that the sensor is defective, the message "PF" (Probe Failure) is also indicated and the alarm is immediately activated. In the event of a "Dew point too low" alarm message (fixed ASL parameter, corresponding to -2°C), the
alarm signal is delayed (ADL parameter) by a fixed period of time of 30 seconds. For the "Dew point too high" message, the value (ASH parameter) is fixed by the user and the signal is activated with an ADH delay time which can
also be set by the user (the control unit was already preset during the acceptance test of the dryer in the factory: see
the following values). As soon as the dew point lies again in the adjusted operating temperature range, the alarm is
deactivated.
The DMC 14 control unit also allows remote signalling of alarm situations of the dryer via a potential-free contact on
terminals 8 and 9 – see enclosed circuit diagrams (max. 250V 1A, min. 5V DC 10mA):
the contact is open when the dryer is switched off or in an alarm condition, and closed when the dryer is switched on
and when the dew point is in accordance with the provisions.
OPERATING PRINCIPLE - When the dryer has been switched on, the electronic control unit indicates the current dew
point: the measured temperature is expressed in °C (● °C) with a resolution of 0,5°C, or in Fahrenheit (● °F) with a
resolution of 1°F.

12.16 Electronically level-controlled BEKOMAT condensate drain
The electronically level-controlled BEKOMAT condensate drain boasts a special condensate management which ensures that condensate is discharged safely and without an unnecessary loss of compressed air. This drain has a condensate collection container in which a capacitive sensor continuously monitors the liquid level. As soon as the switching level is reached, the capacitive sensor transmits a signal to the electronic control and a membrane solenoid valve
opens to discharge the condensate. The BEKOMAT closes before compressed air emerges.
Note:
These BEKOMAT condensate drains were designed in particular for the operation in a DRYPOINT RA
refrigeration dryer. The installation in other compressed-air processing systems or the replacement with
another drain marque can lead to disturbances. The maximum operating pressure (see type plate) must
not be exceeded.
Ensure that the upstream valve is open when the dryer starts operation.
To obtain detailed information regarding drain functions, troubleshooting, maintenance and
spare parts, please read the installation and operating instructions of the BEKOMAT condensate
drain.

13.4 Maintenance works at the refrigeration cycle
Caution!
Refrigerant!
Maintenance and repair works at refrigeration system must only be carried out by BEKO service technicians in accordance with the local provisions.
The total amount of refrigerant in the system must be collected for recycling purposes, resource recovery
or disposal.
The refrigerant must not be discharged into the environment.
When delivered, the dryer is ready to operate and filled with a refrigerant of the R134a or R404A type.
Should you detect a refrigerant leak, please contact a BEKO service technician. Prior to any intervention,
the room needs to be ventilated.
When the refrigeration cycle needs to be refilled, please also contact a BEKO service technician.
You will find the refrigerant type and amount on the type plate of the dryer.
Properties of the refrigerants:
Refrigerant
R134a – H-FKW
R404A – H-FKW
