PROJECT/REQUIREMENTS

• The existing system did not meet the requirements regarding the costs of use and the quality of compressed air. The measured demand for compressed air was 20m3/min, and the required network pressure was 6.5bar. Required pressure dew point +3˚C, solid particles <0.01 micron, oil content <0.01mg/m3.

SOLUTION

• After conducting numerous measurements and analyses of compressed air consumption,the decision was made to replace the existing system with new RSF 127 D compressors. Additionally, a new air treatment system was installed: cyclone separators, pre- and fine filters, refrigerant dryer and pressure maintaining system.
  
  

IMPROVEMENT

• After comparing the operating costs of the old and new compressed air systems, 49.4% of energy was saved. This was possible by eliminating the operation of compressors on idle speed, reducing the network pressure and eliminating the operation of compressors on leaks during the plant's overnight standstill by using a pressure maintaining system and appropriately setting the compressor operating time schedule.
