Mapping of compressed air users revealed that to assemble machines, that are far away from the compressor room demand high compressed air flow. Installing a dedicated air tank for each machine, reduce the sudden pressure drop within the network, and allow for reducing the compressors set point, saving on electricity consumption.

Compressed air is used for water bubbling within galvanizing water. As the pressure setting of the compressed air is high, oil mixes with the air bubbles, and causes qulity problems. Shifting the bubbling to utilize vacuum pumps rather than compressed air improved on the quality, and reduced the energy consumption.
