Benefits from using the actual characteristics

The original factory data can be used to calculate the operational point of the compressor.

The characterizer shows this point, marked with red colour, in a graphical presentation of the range of possible operating points.

Around the calculated operating point, four trying points, marked with blue colour, each corresponding to 5% shift at coordinate axes, are taken and estimated.

In the example case the results were:

Operational point        red      blue 1      blue 2     blue 3     blue 4
Fuel gas cost/day     20.800    21.900    19.600    20.000     21.600

The compressor characterizer automatically brings the compressors to the operational point with the lowest costs and saves in the example case 438.000 USD per year.
