Customer: PS Systec, Germany, Augsburg.
Universal software block to control a group of compressor units: flexible sequence numbers, equalization of running hours, energy consumption optimization (serial and parallel control logic) for continuous (screw) compressors with variable capacity slide position, for compressors with frequency inverters, and for compressors with discrete capacity steps (piston etc). Mixed sequence with continuous-step compressors, swapping of sequence numbers according to regulation priority number.
Flexible master sequence of up to 8 groups with 4 compressors each (32 compressors).
