The highest achievable air mass under the following operating conditions is: − − − − Air inlet pressure = 120 psig (8 barg) Ambient temperature = 115°F (45°C) Air inlet temperature = 122°F (50°C) Pressure dew point = 50°F (10°C) Factor (F1) = 1.07 Factor (F2) = 0.78 Factor (F3) = 0.68 Factor (F4) = 1.36 Every function parameter corresponds to a numerical factor which, multiplied by the planned nominal capacity, determines the following: Actual air throughput = 75 x 1.07 x 0.78 x 0.68 x 1.36 = 58 scfm (99 m³/h) 58 scfm is the maximum flow rate of the dryer under the aforementioned operating conditions. Selection of the best suitable model in accordance with the operating conditions: Requ. air throughput Air throughput acc. to planning = Factor (F1) x Factor (F2) x Factor (F3) x Factor (F4) Example: The following operating parameters are known: 3 − Required air mass = 100 scfm (170 m /h) − Air inlet pressure = 120 psig (8 barg) − Ambient temperature = 115°F (45°C) − Air inlet temperature = 122°F (50°C) − Pressure dew point = 50°F (10°C) Factor (F1) = 1.07 Factor (F2) = 0.78 Factor (F3) = 0.68 Factor (F4) = 1.36 To find out the correct dryer version, the required air mass must be divided by the correction factors of the parameters indicated above: 100 Air throughput acc. to planning = 1.07 x 0.78 x 0.68 x 1.36 = 130 scfm (221 m³/h) The suitable model for these requirements is DRYPOINT RAX 150 (with a spec. nominal capacity 150 scfm [255 m³/h]). 16 DRYPOINT® RAX 20-500 NA Installation 8.4 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 name 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 name 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. 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. ===== Ende der Stüc kli ste ===== Note!

CAUTION! During the piping of the dryer, the inlet and outlet connections need to be supported as is shown in the illustration. Non-observance will cause damage. 18 DRYPOINT® RAX 20-500 NA Installation 8.7 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 name plate to avoid exceeding the indicated values. The voltage tolerance is +/- 10%. DRYPOINT RAX 20-500 NA dryers are supplied with a power cord and safety plug (two-pole and earth connection) or with a junction box on the back plate. Make sure that suitable fuses or circuit breakers in accordance with the indications on the name 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 name 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. 8.8 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 pressurised 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.

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 36°F (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 46°F (8°C) below the inlet temper ature 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. 26 DRYPOINT® RAX 20-500 NA Technical description 11.3 Flow chart (air-cooled) 2 3 4 5 P< TS P> PV 9 M 6 1a 25 7 8 1 1b 12 T1 11 10 DGF0073 1c 21 13 11.4 Flow chart (water-cooled) 2 3 4 5 P< TS P> PV 6 1a 25 18 7 1 1b 19 12 DGF0074 T1 11 1c 21 13 1 20 10 Aluminium heat exchanger module 9 Condenser fan (air cooled) a – Air/air heat exchanger 10 Filter dryer b – Air/refrigerant heat exchanger 11 Capillary tube 12 T1 temperature sensor (dew point) 13 Condensate drain shut-off valve 18 Condenser (water-cooled) 19 Cooling-water regulating valve (water-cooled) 5 c – Condensate separator Refrigerant pressure switch LPS (P<) (RAX 300-500 and RAX 200-500 3~) Safety temperature switch TS (RAX 125-500) Refrigerant pressure switch HPS (P>) (RAX 300-500 and RAX 200-500 3~) Refrigerant fan pressure switch PV 20 Liquid collector (water-cooled) 6 Refrigerating compressor 21 BEKOMAT condensate drain 7 Hot-gas bypass valve 25 Compressor crankcase heater (RAX 200-500 3~) 8 Condenser (air-cooled) 2 3 4 Compressed-air flow direction DRYPOINT® RAX 20-500 NA Refrigerant gas flow direction 27 Technical description 11.5 Refrigerating compressor The employed refrigerating compressors are constructed by leading manufacturers. The hermetically sealed construction is absolutely gastight. The integrated safeguard protects the compressor against overheating and excess current. The protection is automatically reset as soon as the nominal conditions are reached again. 11.6 Condenser (air-cooled) The condenser is the component in which the gas coming from the compressor is cooled down, condensed and liquefied. 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. 11.7 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. 11.8 Cooling-water regulating valve The cooling-water regulating valve serves to keep the condensation pressure or the condensation temperature constant during water cooling. When the dryer is switched off, the valve automatically blocks the cooling-water flow. 11.9 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. 11.10 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. 11.11 Aluminium heat exchanger The heat exchanger module consists of an air/air heat exchanger, an air/refrigerant heat exchanger, and of a highperformance separator. The compressed air flows top-down through the heat exchanger. The large cross-sections of the flow passages cause low flow rates and low compressed-air losses. In the air/air heat exchanger, the heat exchange is effected in a reverse current. This guarantees maximum heat transfer. The heat transfer in the air/refrigerant heat exchanger also takes place in a reverse current. This allows full evaporation of the refrigerant. The high-performance separator ensures almost complete separation of the condensate. Maintenance of the highperformance separator is not required. 11.12 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 and the evaporation pressure remain constant. 28 DRYPOINT® RAX 20-500 NA Technical description 11.13 Refrigerant pressure switches LPS – HPS – PV To ensure the operational reliability and the protection of the dryer, a series of pressure switches are installed in the gas cycle. LPS : Low-pressure guard on the suction side of the compressor, which is triggered when the pressure drops below the predetermined value. The values are reset automatically as soon as the nominal conditions are reestablished. HPS : The high-pressure control unit on the discharge side of the compressor is activated when the pressure exceeds the predetermined value. It has a manual reset button on the control itself. PV : Fan control pressure switch which is installed on the discharge side of the compressor. It keeps the condensation temperature and pressure constantly in the range of the preadjusted limit values (air-cooled) 11.14 Safety temperature switch TS 2 The temperature switch is reset manually, but only when the normal operating conditions are reached again. Unscrew the cover (see pos. 1 in the illustration) and press the reset button (see position 2 in the illustration). PQS0005 1 To ensure the operational safety and the soundness of the dryer, a safety temperature switch (TS) is installed at the refrigeration cycle. In the event that the pressure gas temperature is too high, the sensor of the temperature switch will stop the refrigerating compressor to prevent the pressure gas temperature getting too high. 11.15 Compressor crankcase heater (RAX 200-500 3~) At low temperatures, the oil can more easily intermix with the refrigerant gas. When the compressor starts, oil can be drawn into the refrigeration cycle, leading to "hydraulic shocks". To prevent this, a resistance heater is installed in the suction side of the compressor. When the system is connected with the electric mains and the compressor is idle, the heater will keep the oil at the correct temperature. This heater is controlled via a temperature switch which prevents the overheating of the oil. Note: The heater must be connected to the mains at least a few hours prior to the start-up of the refrigerating compressor.

The correct settings are carried out in the factory and proper functioning is checked during the final inspection of the dryer. DRYPOINT® RAX 20-500 NA 31 Technical description 11.17 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 RAX refrigeration dryer. The installation in other compressed-air processing systems or the replacement with another drain brand can lead to malfunction. The maximum operating pressure (see name plate) must not be exceeded! Ensure that the upstream valve is open when the dryer starts operation.

Refrigerant! Maintenance and repair works at refrigeration systems 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 R407C 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 name plate of the dryer. Properties of the refrigerants used: Refrigerant Chemical formula MIK GWP R134a - HFC CH2FCF3 1000 ppm 1300 R407C - HFC R32/125/134a (23/25/52) CHF2CF3/CH2F2/CH2FCF3 1000 ppm 1653 12.5 Dismantling the dryer When the dryer is dismantled, all parts and operating materials related to the plant need to be disposed of separately. Component Material Refrigerant R404A, R134a, oil Roof and supports Structural steel, epoxy paint coat Refrigerating compressor Steel, copper, aluminium, oil Aluminium heat exchanger Aluminium Condenser unit Aluminium, copper, structural steel Pipe Copper Fan Aluminium, copper, steel Valve Brass, steel BEKOMAT condensate drain PVC, aluminium, steel Insulant Synthetic rubber without CFCs, polysterene, polyurethane Electric cable Copper, PVC Electric parts PVC, copper, brass We recommend observing the safety provisions in force for the disposal of each material type. The refrigerant contains lubricating-oil droplets which are released by the compressor. The refrigerant must not be discharged into the environment. It must to be sucked off from the dryer using a suitable device, and then needs to be supplied to a collection point. 40 DRYPOINT® RAX 20-500 NA Appendices 13 Appendices 13.1 Dryer dimensions 13.1.1 Dryer dimensions DRYPOINT RAX 20-50 NA DRYPOINT® RAX 20-500 NA 41 Appendices 13.1.2 Dryer dimensions DRYPOINT RAX 75 NA 42 DRYPOINT® RAX 20-500 NA Appendices 13.1.3 Dryer dimensions DRYPOINT RAX 100-150 NA DRYPOINT® RAX 20-500 NA 43 Appendices 13.1.4 Dryer dimensions DRYPOINT RAX 200-250 NA 44 DRYPOINT® RAX 20-500 NA Appendices 13.1.5 Dryer dimensions DRYPOINT RAX 300-350 NA DRYPOINT® RAX 20-500 NA 45 Appendices 13.1.6 Dryer dimensions DRYPOINT RAX 400-500 NA 46 DRYPOINT® RAX 20-500 NA Appendices 13.1.7 Dryer dimensions DRYPOINT RAX 200-250 NA 3~ DRYPOINT® RAX 20-500 NA 47 Appendices 13.1.8 Dryer dimensions DRYPOINT RAX 300-350 NA 3~ 48 DRYPOINT® RAX 20-500 NA Appendices 13.1.9 Dryer dimensions DRYPOINT RAX 400-500 NA 3~ DRYPOINT® RAX 20-500 NA 49 Appendices 13.2 Exploded diagrams 13.2.1 Components of the exploded diagrams 1 2 3 4 5 6 7 8 9 10 11 12 13 17 18 19 50 Alu drying module 1.1 Insulation material Refrigerant pressure switch LPS Safety temperature switch TS Refrigerant pressure switch HPS Refrigerant fan pressure switch PV Compressor Hot-gas bypass valve Condenser (air-cooled) Condenser fan 9.1 Motor 9.2 Blade 9.3 Grid Filter dryer Capillary tube T1 temperature probe (dew point) Condensate drain service valve Air dryer control Condenser (water-cooled) Condenser water-regulating valve (water-cooled) 20 21 22 … 51 52 53 54 55 56 57 58 59 60 61 62 65 66 81 100 Refrigerant reservoir (water-cooled) Bekomat drain Main switch Front panel Back plate Right sidewall Left sidewall Cover Base plate Upper plate Carrier support Support bracket Control panel Electric connecting plug Electric cabinet Condenser filter QE door Adhesive label flow chart Autotransformer (supply 3/380/60 only) DRYPOINT® RAX 20-500 NA Appendices 13.2.2 Exploded diagram DRYPOINT RAX 20-30 NA / AC DRYPOINT® RAX 20-500 NA 51 Appendices 13.2.3 Exploded diagram DRYPOINT RAX 50 NA / AC 52 DRYPOINT® RAX 20-500 NA Appendices 13.2.4 Exploded diagram DRYPOINT RAX 75 NA / AC DRYPOINT® RAX 20-500 NA 53 Appendices 13.2.5 Exploded diagram DRYPOINT RAX 100 NA / AC 54 DRYPOINT® RAX 20-500 NA Appendices 13.2.6 Exploded diagram DRYPOINT RAX 125-150 NA / AC DRYPOINT® RAX 20-500 NA 55 Appendices 13.2.7 Exploded diagram DRYPOINT RAX 200-250 NA / AC 56 DRYPOINT® RAX 20-500 NA Appendices 13.2.8 Exploded diagram DRYPOINT RAX 300-350 NA / AC DRYPOINT® RAX 20-500 NA 57 Appendices 13.2.9 Exploded diagram DRYPOINT RAX 400-500 / AC 58 DRYPOINT® RAX 20-500 NA Appendices 13.2.10 Exploded diagram DRYPOINT RAX 200-250 NA / WC DRYPOINT® RAX 20-500 NA 59 Appendices 13.2.11 Exploded diagram DRYPOINT RAX 300-350 NA / WC 60 DRYPOINT® RAX 20-500 NA Appendices 13.2.12 Exploded diagram DRYPOINT RAX 400-500 NA / WC DRYPOINT® RAX 20-500 NA 61 Appendices 13.2.13 Exploded diagram DRYPOINT RAX 200-250 NA 3~ / AC 62 DRYPOINT® RAX 20-500 NA Appendices 13.2.14 Exploded diagram DRYPOINT RAX 300-350 NA 3~ / AC DRYPOINT® RAX 20-500 NA 63 Appendices 13.2.15 Exploded diagram DRYPOINT RAX 400-500 NA 3~ / AC 64 DRYPOINT® RAX 20-500 NA Appendices 13.2.16 Exploded diagram DRYPOINT RAX 200-250 3~ / WC DRYPOINT® RAX 20-500 NA 65 Appendices 13.2.17 Exploded diagram DRYPOINT RAX 300-350 NA 3~ / WC 66 DRYPOINT® RAX 20-500 NA Appendices 13.2.18 Exploded diagram DRYPOINT RAX 400-500 3~ / WC DRYPOINT® RAX 20-500 NA 67 Appendices 13.3 Electric diagrams 13.3.1 Electric diagrams – list of components MC : MV : DMC18 : HPS LPS PV TS ELD S1 QS RC TR BOX : : : : : : : : : : Compressor KT : Compressor thermal protection KR : Compressor starting relay (if installed) CS : Compressor starting capacitor (if installed) CR : Compressor operating capacitor (if installed) Condenser fan CV : Fan starting capacitor (if installed) DMC18 electronic instrument – air dryer control BT1 : T1 Temperature probe – dew point Pressure switch – compressor discharge side (HIGH PRESSURE) Pressure switch – compressor suction side (LOW PRESSURE) Pressure switch – fan control Safety temperature switch BEKOMAT drain ON/OFF switch Main switch with locking device Compressor crankcase heater Autotransformer ( supply 3/380/60 only) Electrical connection NT1 NT2 NT3 NT4 NT5 NT6 NT7 : : : : : : : Only air-cooled Check the transformer connections with regard to the supply voltage Jump, if not installed Provided and cabled by the customer Internal control Time-controlled drain outlet (not used) Only water-cooled BN BU BK YG 68 = = = = BROWN BLUE BLACK YELLOW/GREEN OR RD WH WH/BK = = = = ORANGE RED WHITE WHITE/BLACK DRYPOINT® RAX 20-500 NA PE 5 BU-2 4 PE N 2 http:// www.beko.de 4 2 C CS M S 1~ KT MC1 3 KR R CV MV1 1 2 4 M 1~ PV 4 5 7 3 2 3 2 5 ELD 8 S 9 10 G +24V Drn Sen Gnd 7 +24V D 8 °C °F NTC 2k BT1 11 T1 BM 31-IF ELD DRAIN MODEL SELECT. 9 Sheet 01 of 01 00 Note : Rev.
