Fuel saving technologies can be considered by subtracting the corresponding power demand from the power demand of the baseline compressor.
The following combinations of technologies are not considered:
(a) ESS and clutches
(b) Visco clutch and mechanical clutch
In case of a two-stage compressor, the displacement of the first stage shall be used to describe the size of the air compressor system
