Buying a compressed air receiver can’t be that hard, can it?<\/h2><\/div>

For experienced users, that may well be true. Even so, many of our customers are glad to receive good advice when making their decision. Better safe than sorry. Not least because T\u00dcV inspection also plays a role with compressed air receivers…<\/p>\n

What are the advantages of compressed air receivers? Does it have anything to do with the type of compressor?<\/h3>\n<\/div>
    \n
  1. Buffering compressed air: <\/span>This is particularly useful with screw compressors, as they usually produce valuable compressed air continuously, even when air demand is low at the time. If a receiver is available, the surplus compressed air can be stored there. If the consumption later exceeds the compressor’s free air delivery, a buffer tank helps to bridge this phase. For the user, the compressed air reserve means more flexibility in sizing the compressor and in the number of consumers.<\/li>\n
  2. Damping pulsations: <\/span>Piston compressors generate pulsations that can disrupt the operation of sensitive equipment. A compressed air receiver installed between the compressor and the consumer smooths the flow so that volume fluctuations no longer occur.<\/li>\n
  3. Minimising compressor cycles<\/span>: By storing compressed air, compressors have to run fewer cycles, which puts less strain on the motor.<\/li>\n
  4. Cooling and drying:<\/span> If the air first passes through a receiver, it cools down there. Part of the moisture separates out as condensate, which relieves the load on the dryer. However, this sequence is not always suitable, especially as correct compressed air treatment is a complex subject. Please seek advice from a specialist company.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

    Vertical or horizontal receiver: which version is better?<\/h3>\n<\/div>

    Neither version is better, but there are differences in footprint. A vertical receiver is more compact in this respect, which is an advantage where space is tight.<\/p>\n

    At the same time, there are compressors that are mounted on a horizontal receiver. Taking into account the floor space saved for the compressor, this version also uses the available space very efficiently.<\/p>\n<\/div><\/div><\/div>

    Do I need a compressed air receiver at all?<\/h3>\n<\/div>

    Compressed air receivers are essential components of industrial compressed air systems and should definitely be taken into account at the planning stage. Although the reasons vary, a storage unit usually makes sense, regardless of the type of compressor. With piston compressors, the air receiver is always included, because the motor receives the signal to start from the pressure drop in the receiver.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

    What is an AD2000 receiver?<\/h3>\n<\/div>
    <\/div>
    \"Piston<\/span><\/div><\/div><\/div>

    An AD 2000 receiver is not a specific type of receiver, but a pressure vessel manufactured in accordance with the AD 2000 code. This code summarises and specifies the testing requirements of the European Pressure Equipment Directive<\/a>. It is written by the Arbeitsgemeinschaft Druckbeh\u00e4lter (AD, Pressure Vessel Working Group) in cooperation with the DGUV, the VDMA and other stakeholder groups. The publisher is the T\u00dcV-Verband e.V.<\/p>\n

    The authors’ aim was to formulate the safety requirements in a practical and understandable way. However, the AD 2000 code is not a standard in the strict sense, but a conformity assessment for pressure equipment in the EU. In Germany, the AD 2000 data sheets are often regarded as a national code and effectively fulfil the function of a standard. Thanks to its clear structure and generous inspection intervals, AD 2000 is very popular with both manufacturers and operators of pressure vessels.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

    What is the difference between galvanised and powder-coated air receivers?<\/h3>\n<\/div>

    As is so often the case, it depends on the intended use and the environment of the pressure vessel. Personal preferences regarding the appearance of the receiver can also influence the decision. Ultimately, both coating options have their advantages and disadvantages:<\/p>\n
