What is the maximum allowable flow through the dryer under the following operating conditions: Inlet air pressure = 50 barg Factor (F1) = 1.06 Ambient temperature = 45 C Inlet air temperature = 50 C Factor (F2) = 0.88 Factor (F) = 0.70 Pressure DewPoint = 10 C Factor (F4) = 1.7 Each item of data has a corresponding numerical factor which multiplied by the design air flow is as follows: Air flow capacity = 240 x 1.06 x 0.88 x 0.70 x 1.7 = 215 m³/h 215 m³/h This 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 = Example: With the following operating parameters: Design air flow = 165 m³/h Inlet air pressure = 50 barg Ambient temperature = 45 C Inlet air temperature = 50 C Pressure DewPoint = 10 C Design air flow Factor (F1) x Factor (F2) x Factor (F) x Factor (F4) Factor (F1) = 1.06 Factor (F2) = 0.88 Factor (F) = 0.70 Factor (F4) = 1.7 In order to select the correct dryer model the required flow rate is to be divided by the correction factors relating to above mentioned parameters: 165 Minimum std. air flow rate = = 185 m³/h 1.06 x 0.88 x 0.70 x 1.7 Therefore the model suitable for the conditions above is DRYPOINT RS HP50 40 (240 m³/h nominal duty). 10 DRYPOINT RS 4C 500 HP50
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.). DRYPOINT RS 4C 500 HP50 11
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. The dryers DRYPOINT RS 4C-100 HP50 come with a mains connecting cable already installed and ending with a VDE 16A - Shucko plug; while the dryers DRYPOINT RS 10-500 HP50 come with an electric box for the connection to the mains. The mains socket must be provided with a mains magneto-thermal differential breaker (I n=0.0a), 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. 12 DRYPOINT RS 4C 500 HP50

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 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 8 degrees 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. 24 DRYPOINT RS 4C 500 HP50

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 Water- Cooled 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 42-45 C. 26 DRYPOINT RS 4C 500 HP50
Technical description 5.9. Filter Dryer 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. 5.1. 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 P A 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. DRYPOINT RS 4C 500 HP50 27
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. 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 (position A on the drawing) until the following value is reached: Hot gas setting (R14.a) : temperature 0.5 C (+0.5 / -0 K) pressure 2.0 barg (+0.1 / -0 bar) Hot gas setting (R404A) : temperature 0.5 C (+0. 5 / -0 K) pressure 5.2 barg (+0.1 / -0 bar) DRYPOINT RS 4C-0 HP50 VLY0001 - + A 4 mm 5/2 in.

Safety thermo-switch T s 2 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. 1 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). PQS0005 TS setting : temperature 100 C (+2 / -2 K) 5.18. Compressor crankcase heater (DRYPOINT RS 200-500 HP50) 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. DRYPOINT RS 4C 500 HP50 29

Technical description 5.22. 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. 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. 8 DRYPOINT RS 4C 500 HP50
