Peak load optimization at the Herborner Pumpenfabrik

The company had in the year 2007 a peak load of 600 kW. They had been charged with the three peak loads of the three highest month measurements.

The maximum load could be reduced by 180 kW down to 420 kW. This reduction has been achieved by means of a PDMS, i.e. through short term disconnection and speed reduction of pre-defined loads.

Typical loads were VFD driven ventilators, which could be reduced in speed, as well as large scale compressors. As a first step a AMR (automatic meter reading) system for the various media, such as Gas, Water, Oil, Electricity had been installed. These data are used for some tax benefit reasons.

On top a level monitoring system for oxygen and glass sand has been implemented. In case of undercutting the minimum level an Email is triggered informing the purchasing department ordering new materials.
