CAUTION!
Polluted inlet air!
In case of heavily polluted inlet air (ISO 8573.1 class 3.-.3 or worse quality), we recommend the additional
installation of a pre-filter (f.e. CLEARPOINT F040) to prevent a clogging of the heat exchanger
Type A installation is suggested when the compressor operates at reduced intermittence and the total consumption
equals the compressor flow rate.
Type B installation is suggested when the air consumption can consistently change with peak values highly exceeding
the flow rate of the compressor. The capacity of the tank must be sized in order to compensate eventual instantaneous
demand conditions (peak air consumption).

How to find the air flow capacity:
Air flow capacity = Nominal duty x Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)
Example:
An DRYPOINT RS 100 HP50 NA has a nominal duty of 100 scfm (170 m³/h). What is the maximum allowable flow
through the dryer under the following operating conditions:
–
–
–
–
Inlet air pressure = 650 psig (45 barg)
Ambient temperature = 105°F (40°C)
Inlet air temperature = 130°F (55°C)
Pressure DewPoint = 38°F (3°C)
Factor (F1) = 1.03
Factor (F2) = 0.94
Factor (F3) = 0.63
Factor (F4) = 1.00
Each item of data has a corresponding numerical factor as follows:
Air flow capacity = 100 x 1.03 x 0.94 x 0.63 x1.00 = 61 scfm (104 m³/h)
61 scfm (104 m³/h) is the maximum flow rate that the dryer can accept under these operating conditions.
How to select a suitable dryer for a given duty:
Minimum std. air flow rate =
Design air flow
Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4)
Example:
– Design air flow = 90 (153 m³/h)
– Inlet air pressure = 650 psig (45 barg) Factor (F1) = 1.03
– Ambient temperature = 105°F (40°C) Factor (F2) = 0.94
Factor (F3) = 0.63
– Inlet air temperature = 130°F (55°C)
Factor (F4) = 1.00
– Pressure DewPoint = 38°F (3°C)
Each item of data has a corresponding numerical factor as follows:
90
Minimum std. air flow rate =
= 148 scfm (251 m³/h)
1.03 x 0.94 x 0.63 x 1.00
Therefore the model suitable for the conditions above is DRYPOINT RS 180 HP50 NA 180 scfm or 306 m³/h nominal duty).

Installation
2.6.
Connection to the Compressed Air System
DANGER!
Compressed air!
Operations to be performed by qualified personnel only.
Never work on compressed air system under pressure.
The user is responsible to ensure that the dryer will never be operated with pressure exceeding the maximum
pressure rating on the unit data tag.
Over-pressurizing the dryer could be dangerous for both the operator and the unit.
The air temperature and the flow entering the dryer must comply within the limits stated on the data nameplate. The
system connecting piping must be kept free from dust, rust, chips and other impurities, and must be consistent with the
flow-rate of the dryer. In case of treatment of air at particularly high temperature, the installation of a final refrigerator
could result necessary. In order to perform maintenance operations, it recommended that a dryer by-pass system be
installed as shown in the following illustration.
In realising the dryer, particular measures have been taken in order to limit the vibration which could occur during the
operation. Therefore we recommend to use connecting pipes able to insulate the dryer from possible vibrations
originating from the line (flexible hoses, vibration damping fittings, etc.).
CAUTION:
Piping the dryer, inlet/outlet connections must be supported as show in the diagram.
Failing will result in damage.
2.7.
Connection to the Cooling Water Network (Water-Cooled)
DANGER!
Compressed air and unqualified personnel!
Operations to be performed by qualified personnel.
Never operate with plants under pressure.
The user is responsible to ensure that the dryer will never be operated with pressure exceeding the nominal
values.
Eventual over-pressure could be dangerous both for the operator and the machine.
The temperature and the amount of cooling water must comply with the limits indicated on the technical characteristics
chart. The cross section of the connection pipes, preferably flexible, must be free from rust, chips and other impurities.
We recommend to use connecting pipes able to insulate the dryer from possible vibrations originating from the line
(flexible hoses, vibration damping fittings, etc.).

Installation
2.8.
Electrical connections
DANGER!
Supply voltage!
Qualified personnel should carry out connecting unit to the main power.
Be sure to check the local codes in your area.
Before connecting the unit to the electric power, verify that the voltage and the frequency available on the mains
correspond to the data reported on the data plate of the dryer. In terms of voltage, a ±5% tolerance is allowed.
Dryer supplied at 115/1/60 voltage comes with a mains connecting cable already installed and ending with a NorthAmerican standard plug 2 poles + ground. Dryer supplied at 230/1/60 and 460/3/60 voltages comes with a box for the
connection to the mains.
The mains socket must be provided with a mains magneto-thermal differential breaker (I∆n=0.03A), adjusted on the
basis of the consumption of the dryer (see the nominal values on the data plate of the dryer).
The cross section of the power supply cables must comply with the consumption of the dryer, while keeping into
account also the ambient temperature, the conditions of the mains installation, the length of the cables, and the
requirements enforced by the local Power Provider.
DANGER!
Mains voltage and missing earthing!
Important: ensure that the plant is earthed.
Do not use any socket adapters at the mains plug.
If the mains plug needs to be replaced, this must only be done by a qualified electrician
2.9.
Condensate Drain
DANGER!
Compressed air and pressurized condensate!
The condensate is discharge at the system pressure.
Drain line should be secured.
Never point the condensate drain line towards anybody.
The dryer comes already fitted with an electronically level controlled BEKOMAT condensate drain. Connect and
properly fasten the condensate drain to a collecting plant or container.
The drain cannot be connected to pressurized systems.
Don’t dispose the condensate in the environment.
The condensate collected in the dryer contains oil particles released in the air by the compressor.
Dispose the condensate in compliance with the local rules.
We suggest to install a water-oil separator where to convey all the condensate drain coming from
compressors, dryers, tanks, filters, etc. We recommend ÖWAMAT oil-water separators for disperse
compressor condensate, BEKOSPLIT emulsion splitters for emulsified condensate.

Operation
Operating principal – The dryer models described in this manual operate all on the same principal. The hot moisture
laden air enters an air to air heat exchanger. The air then goes through the evaporator, also known as the air to
refrigerant heat exchanger. The temperature of the air is reduced to approximately 36°F (2°C), causing water vapor to
condense to liquid. The liquid is continuously coalesced and collected in the separator for removal by the condensate
drain. The cool moisture free air then passes back through the air to air heat exchanger to be reheated to within 15
degrees °F (8 degrees °C) of the incoming air temperature as it exits the dryer.
Refrigerant circuit - Refrigerant gas is cycled through the compressor and exits at high pressure to a condenser where
heat is removed causing the refrigerant to condense to a high-pressure liquid state. The liquid is forced through a
capillary tube where the resulting pressure drop allows the refrigerant to boil off at a predetermined temperature. Lowpressure liquid refrigerant enters the heat exchanger where heat from the incoming air is transferred causing the
refrigerant to boil; the resulting phase change produces a low pressure, low temperature gas. The low-pressure gas is
returned to the compressor, where it is re-compressed and begins the cycle again. During those periods when the
compressed air load is reduced the excess refrigerant is by-passed automatically back to the compressor via the Hot
Gas By-pass Valve circuit.

Technical description
5.5.
Refrigerating compressor
The refrigerating compressor is the pump in the system, gas coming from the evaporator (low pressure side) is
compressed up to the condensation pressure (high pressure side). The compressors utilized are manufactured by
leading manufacturers and are designed for applications where high compression ratios and wide temperature changes
are present.
The hermetically sealed construction is perfectly gas tight, ensuring high-energy efficiency and long, useful life.
Dumping springs support the pumping unit in order to reduce the acoustic emission and the vibration diffusion. The
aspirated refrigerating gas, flowing through the coils before reaching the compression cylinders cools the electric
motor. The thermal protection protects the compressor from over heating and over currents. The protection is
automatically restored as soon as the nominal temperature conditions are reached.
5.6.
Condenser (Air-Cooled)
The condenser is the component in which the gas coming from the compressor is cooled down and condensed
becoming a liquid. Mechanically, a serpentine copper tubing circuit (with the gas flowing inside) is encapsulated in an
aluminum fin package.
The cooling operation occurs via a high efficiency fan, creating airflow within the dryer, moving air through the fin
package. It’s mandatory that the ambient air temperature does not exceed the nominal values. It is also important to
keep the condenser unit free from dust and other impurities.
5.7.
Condenser (Water-Cooled)
The condenser is the component in which the gas coming from the compressor is cooled down and condensed
becoming a liquid. Basically it is a water/refrigerating gas exchanger where the cooling water lowers the temperature of
the refrigerating gas.
The temperature of the inlet water must not exceed the nominal values. It must also guarantee an adequate flow and
that the water entering the exchanger is free from dust and other impurities.
5.8.
Condenser water regulating valve (Water-Cooled)
The condenser water regulating valve is used to keep the condensing pressure/temperature constant when the WaterCooled is being used. Thanks to the capillary tube, the valve detects the pressure in the condenser and consequently
adjusts the water flow. When the dryer stops the valve automatically closes the cooling water flow.
CAUTION!
The condenser water regulating valve is an operating control device.
The closure of the water circuit from the pressure condenser water regulating valve cannot be used as a
safety closure during service operations on the system.
ADJUSTMENT
The condenser water regulating valve is adjusted during the testing phase to a pre-set value that covers 90%
of the applications. However, sometimes the extreme operating conditions of the dryer may require a more
accurate calibration.
During start-up, a qualified technician should check the condensing pressure/temperature and if necessary
adjust the valve by using the screws on the valve itself.
To increase the condensing temperature, turn the adjusting screws counter-clockwise; to lower it turn the
screws clock-wise. Adjust the valve in order to guarantee a condensing temperature of 108-113 °F (42-45 °C).

DRYPOINT® RS 15 – 1700 HP50 NA
Technical description
5.9.
Filter Drier
Traces of humidity and slag can accumulate inside the refrigerating circuit. Long periods of use can also produce
sludge. This can limit the lubrication efficiency of the compressor and clog the expansion valve or capillary tube. The
function of the Filter Drier, located before the capillary tubing, is to eliminate any impurities from circulating through the
system.
5.10. Capillary Tube
It consists of a piece of reduced cross section copper tubing located between the condenser and the evaporator, acting
as a metering device to reduce the pressure of the refrigerant. Reduction of pressure is a design function to achieve
optimum temperature reached within the evaporator: the smaller the capillary tube outlet pressure, the lower the
evaporation temperature.
The length and interior diameter of the capillary tubing is accurately sized to establish the performance of the dryer; no
maintenance or adjustment is necessary.
5.11. Air-to-air heat exchanger
The purpose of this exchanger is to drop the heat of the incoming compressed air onto the outgoing cold air. The
benefits of this solution are essentially two: the incoming air is already partially cooled so the refrigerating circuit can be
sized as to assure a limited thermal head, with a 40÷50% energy saving. Secondly no cold air is allowed into the
compressed air line, thus preventing the formation of condensate on the external surface of the system’s tubes.
5.12. Evaporator
Also called an air-refrigerant exchanger. The liquid formed in the condenser is evaporated in this part of the circuit. In
the evaporation phase the refrigerator tends to absorb the heat from the compressed air present in the other side of the
exchanger.
Refrigerant and air are in counter flow, thus contributing to limit pressure drop and to provide efficient thermal
exchange.
5.13. Condensate separator
The cold air exiting the evaporator goes through the hi-efficiency condensate separator featuring a stainless steel mesh.
As the condensate transported by the air gets in contact with the mesh net it is separated and expelled by means of the
draining device. The resulting cold and dry air is then conveyed into the dryer outlet.
The mesh type mist separator offers the benefit to be highly efficient even with variable flow rates.
5.14. Refrigerant relief valve
When, due to any kind of fault or malfunctioning, the pressure of the refrigerating gas circuit is higher than the nominal
conditions, the PA pressure switch will stop the refrigerating compressor.
A safety valve that requires no adjustment, has been installed as a further safety device, also to prevent the problems
caused by over-pressures of the refrigerating gas. The purpose of this valve is to release the over-pressures inside the
circuit. After this gas leak, the dryer is no longer capable of operating correctly. An extraordinary maintenance
intervention is needed to check and especially eliminate the cause that generated the over-pressure, in addition to
reloading the refrigerating gas.

Technical description
5.15. Hot Gas By-pass Valve
This valve injects part of the hot gas (taken from the discharge side of the compressor) in the pipe between the
evaporator and the suction side of the compressor, keeping the evaporation temperature/pressure constant at approx.
+2 °C. This injection prevents the formation of ice inside the dryer evaporator at every load condition.
Hot gas setting (R404A) :

ADJUSTMENT
The Hot Gas By-pass Valve is adjusted during the manufacturing testing
phase. As a rule no adjustment is required; anyway if it is necessary the
operation must be carried out by an experienced refrigerating engineer.
WARNING!
the use of ¼” Schrader service valves must be justified by a real
malfunction of the refrigerating system. Each time a pressure gauge is
connected, a part of refrigerant is exhausted.
Without compressed air flow through the dryer, rotate the adjusting screw

To protect the operating safety and the integrity of the dryer, a thermo-switch (TS)
is installed on the refrigerant gas circuit. The thermo-switch sensor, in case of
unusual discharge temperatures, stops the refrigerating compressor before it is
permanently damaged.
Manually reset the thermo-switch only after the nominal operating conditions have
been restored. Unscrew the relative cap (see pos.1 in the figure) and press the
reset button (see pos.2 in the figure).

5.18. Compressor crankcase heater (DRYPOINT RS 700-1700 HP50 NA)
At low temperatures oil can more easily be mixed with the refrigerant gas. So, when the compressor starts, oil can be
drawn into the refrigeration circuit and liquid hammering could occur.
To prevent this, an electrical resistance heater is installed in the suction side of the compressor. When the system is
powered and the compressor is not running, this heater keeps the oil at the correct temperature.
This heater is controlled by a thermo-switch which prevents overheating the oil.
NOTE : The heater must be powered at least a couple of hours before the start up of the refrigeration compressor.

DISPLAY
The DMC15 electronic controller performs the following functions : it shows the current operating DewPoint through the
digital led display which is detected from the (T1) probe located at the end of the evaporator, while a second (T2) probe,
located on the discharge side of the condenser, activates the relevant fan.
OPERATION - During the dryer operation, the LED
is on.
Thermometer - The 10 LED display indicates the current operating DewPoint, shown by means of a two colours (green
- red) bar over the display itself.
• Green section - operating conditions ensuring an optimal DewPoint;
• Red section - DewPoint of the dryer too high, the dryer is working with elevated thermal load (high inlet air
temperature, high ambient temperature, etc.). The treatment of the compressed air may be improper.
Too high DewPoint temperature, value exceeding the upper limit of the instrument range, is indicated by the intermittent
flashing of the last LED; whereas the intermittent flashing of the first LED shows too low DewPoint temperature.
A possible (T1) probe failure is indicated by the intermittent flashing of the first and last LED of the display, whereas the
dryer keeps on working correctly.
Thermostat - The fan condenser is activated when the condensate temperature reaches or exceeds 95°F (35°C)

Electronic level controlled condensate drain BEKOMAT
The electronic level controlled drain BEKOMAT has a special condensate management that makes sure that
condensate is drained safely without any unnecessary air-loss. This drain consists of a condensate accumulator where
a capacitive sensor continuously checking liquid level is placed: as soon as the accumulator is filled, the sensor passes
a signal to the electronic control and a diaphragm solenoid valve will open to discharge the condensate. Right in time
the discharge line will be closed again without wasting compressed air.
ATTENTION!
These BEKOMAT condensate drains have been specially designed for the use in a refrigerant dryer DRYPOINT RS
HP50 NA. Any Installation in other compressed air treatment units or the exchange against a different drain brand may
lead to malfunction. Do not exceed the max. operating pressure (see type plate)!
Make sure when the dryer starts the upstream valve is open.
NOTE:
For detailed information on drainer functions, troubleshooting, service and replacement parts, please refer to
the BEKOMAT drainer manual.
