ENERGY SAVING In order to save energy at compressed air consumption, these can be done; • Compressors should be selected from the right type and size • Air receiver size should be selected properly. • Air piping and pipe size should be appropriate. • Cool, clean and dry air should enter the compressor inlet. • Periodical maintenance must be done to the compressed air equipment. 2

ENERGY SAVING • Air leakages should be prevented. • Compressor should work at the

ENERGY SAVING • Air leakages should be prevented. • Compressor should work at the lowest pressure possible • Where possible, waste heat should be reused. • Equipment should be lubricated properly. • If there is fluctuating air consumption, variable speed drive should be used. • Efficient motor and fan should be used. 3

PROPORTIONAL CONTROL VALVE • When compressor is operating on loaded or unloaded condition, intake control valve operates in fully open or fully closed position, respectively. • By proportional control valve, intake control valve does not operate only in fully open or fully closed positions, but also in different positions by adjusting itself according to the amount of air required.

ENERGY SAVING – Variable speed drive controlled compressors detect the required amount of air

ENERGY SAVING – Variable speed drive controlled compressors detect the required amount of air with their pressure sensor and they change motor speed in order to fix the compressor pressure. Energy consumption Maintenance – With variable speed drive, pressure is controlled more accurately and it allows using the compressor at lower and precise pressure values.
