Operating instructions in accordance with the 97/23/EC Pressure Equipment Directive Operating instructions in accordance with the 97/23/EC Pressure Equipment Directive The DRYPOINT® RA 20-960 compressed-air refrigeration dryer contains pressure equipment in the sense of the 97/23/EC Pressure Equipment Directive. Therefore, the entire plant needs to be registered with the supervisory authority if required in accordance with the local regulations.
Transport Transport Check the packaging for visible loss or damage. If no visible damage can be ascertained, place the unit in close proximity to the place of installation and unpack the device. During this procedure, the dryer must always remain in an upright position. The components may be damaged when the unit is tilted or turned upside down.
Installation Installation 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 condense 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.
Installation Installation plan - A - Air compressor Aftercooler Condensate separator Prefilter Bypass group Dryer Compressed-air tank - B - Final filter Bekomat condensate drain Installation type A is recommended 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.
Installation 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.
Installation Minimum cooling water requirements: 15 … 30°C (1) / SO >1.0 mg/l or ppm Temperature Pressure 3…10 bar(g) (2) <2 mg/l or ppm Delivery pressure > 3 bar (2) (3) 50 mg/l or ppm Total hardness 6.0…15 dH° 0.5 mg/l or ppm 7.5…9.0 <0.05 mg/l or ppm Conductivity...
Installation 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%.
Start-up Start-up Preliminary stages Note! Exceeding of the operating parameters! Ensure that the operating parameters comply with the nominal values indicated on the name plate of the dryer (voltage, frequency, air pressure, air temperature, ambient temperature etc.). Prior to delivery, this dryer was thoroughly tested, packed and checked. Please verify the soundness of the dryer during the initial start-up and check the perfect functioning during the first operating hours.
Start-up Note! A dew point between 0°C and +10°C displayed on the DMC 18 control unit is considered to be correct according to the possible operating conditions (flow rate, air inlet temperature, ambient temperature etc.). During the operation, the refrigerating compressor runs continuously. The dryer needs to be switched on during the entire compressed-air usage time, even if the compressed-air compressor works periodically.

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.
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.

Technical description 11.16.5 Operation of the potential-free failure/alarm contact The DMC 18 is equipped with a potential-free contact to indicate failures or alarm conditions. Dryer is switched on and no service warning/alarm is active. Dryer is off or a service warning/alarm is active. 11.16.6 How to change operating parameters –...
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.
