Atlas Copco’s ES central controllers allow you to monitor and control multiple vacuum pumps simultaneously. Four ES controller models are available; two integrated system and two of which even enable competitive vacuum pump brands to be controlled. The operating principle is simple: one GHS VSD+ in your multi-pump installation regulates, while the other units are in base load, running at a certain percentage of the maximum speed.
