Our high-pressure storage systems for compressor units: For high operational reliability and cost-effective production
Modular system structure: The ideal way to expand your compressor system
Storage systems for a wide range of pressure stages: dimensioned for 330, 365 and 420 bar
Modular high-pressure storage systems by BAUER KOMPRESSOREN are the ideal way to expand a compressor system.
These high-performance storage systems support the short-term storage of large quantities of air and gas and a constant volume flow.
At the same time, a carefully selected storage module optimises compressor distribution during runtime and also serves as a pulsation damper.
The storage systems are available in pressure stages of 330, 365 and 420 bar. They can be expanded as required by adding 50 or 80 l storage bottles.
All the information you need at your fingertips!
The storage bottles conform to the European Pressure Equipment Directive (PED) 97/32/EC and are designed for stationary applications.
Condensate can accumulate even in high-pressure storage systems as a consequence of application conditions or due to inadequate air or gas treatment. Therefore, all standard storage vessels by BAUER KOMPRESSOREN have a manual condensate drain.
How do I select the size of the storage system correctly to limit the number of start/stop cycles and load cycles?
The following information answers this important question and will help you to find the right storage system for your requirements.
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.
For your safety, cycle counters are installed in BAUER industrial compressors as standard to record the number of cycles actually completed.
The size of the storage system is determined by:
- 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:
Vk × 4
|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 up to max. 60 bar. Up to this difference, stationary HP storage bottles are generally permitted for use in continuous operation.
Above this level, the vessels are limited with regard to the number of filling cycles.
The standard module comprises 1 or 2 storage bottles which are supplied with pipes assembled and ready for connection on a console for mounting either on the floor or on the wall. Safety valve and pressure gauge are included in the standard scope of supply. This is essential if no other means of preventing the maximum permissible storage pressure from being exceeded is in place, e.g. approved safety valves on the compressor or in the supply line.
The add-on module comprises 1 or 2 storage bottles which are supplied with pipes assembled and ready for connection on a console for mounting either on the floor or on the wall. Should the overall storage volume need to be increased, these addon modules can be easily connected to a standard module.
Unlike the standard module, the add-on modules do not have a safety valve or pressure gauge.
