A correctly dimensioned (storage) vessel is one of the most important components of the entire system.

It will reduce pressure fluctuations when large amounts of air are consumed and minimise the number of compressor on/off cycles by providing the correct storage capacity.

For high-pressure compressors, remember that the final separator in the compressor and the storage vessel are only dimensioned for a certain number of load cycles, i.e.: the fewer compressor switching cycles, the longer the service life of these components.

To optimise the performance of the unit and maximise the service life of the final separator based on the number of permissible load cycles, the operation of the compressor should be regulated so that there are no more than 4 ON cycles every hour.

Limiting start/stop cycles and load cycles

How do I select the size of the storage system correctly to limit the number of start/stop cycles and load cycles?

The size of the storage system is determined by the following factors:

  • Free air delivery (l/min) of the compressor
  • Air consumption of the application concerned
  • Pressure difference between start and stop (hysteresis)

Simplified formula for the configuration of a high-pressure storage system based on 4 load cycles/hour:

V(l)

=

Vk × 4
---------
Δp

Vk (l/min) = Delivery rate of the compressor in litres per minute
V(l) = Storage volume in litres (water volume)
Δ p (bar) = Start/stop pressure difference (hysteresis) in bar

We recommend a pressure difference (Δ p) of max. 60 bar. TÜV approval is not compromised in any way up to this setting.

Setting the pressure difference is higher than this will limit the number of cylinder filling operations. You can also optimise the filling of composite cylinders!

Our pressure vessels conform to the European Pressure Equipment Directive (PED) 97/32/EC and are designed for stationary applications.

If you experience problems selecting the ideal storage system for your filling requirements, please contact BAUER KOMPRESSOREN GmbH or one of our partners/distributors.
