Operating instructions in accordance with the 2014/68/EU Pressure Equipment Directive Operating instructions in accordance with the 2014/68/EU Pressure Equipment Directive The DRYPOINT® RS 15-550 HP50 NA high pressure compressed-air refrigeration dryer contains pressure equipment in the sense of the 2014/68/EU Pressure Equipment Directive. Therefore, the entire plant needs to be registered with the supervisory authority if required in accordance with the local regulations.
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 Air compressor Aftercooler Condensate separator Prefilter Bypass group Dryer Compressed-air tank 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.
Start-up 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 Initial start-up Note! The dryer must not be started up more than six times an hour. Wait at least five minutes prior to every restart. The user is responsible for the compliance with these provisions. Irreparable damage can be caused by starting up the device too often.
Start-up Shut down and restart RS 180-550 3phase - during short-term inactivity (max. two to three days), it is advisable to leave the dryer and the control panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the dryer to wait two hours, until the crankcase heater of the compressor has heated up the oil in the compressor.

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 11.15 Refrigerant pressure switches LPS – HPS 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 11.19.5 How is controlled the condenser fan A pressure probe BP2 is located on the discharge side of the compressor. The condenser fan is activated (ON) when the BP2 pressure is higher than FANon setting (R134a approx. 11 barg/160 psig – R407C approx. 18 barg/260 psig) and is ON.
11.20 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.
