Atlas Copco ES controllers for multiple compressor installations

Click2Contact

Atlas Copco’s ES controllers increase the efficiency of multiple-machine installations. Offering a range of control and monitoring functions, the controllers can help reduce the pressure band of the compressed air or vacuum installation, equalise the running hours and minimise the unloaded running of the machines.

With a multiple compressor installation, the ES system will select the machine(s) to run based on demand and when air is needed in the air net, which ensures efficient use of energy. In an installation with multiple VSD air compressors, one compressor will regulate the demand and the other compressors will run at optimal speed.

The core function of the system is to equalise the running hours of a multiple air compressor or vacuum pump installations, which will enable effective and equal use of all machines within the installation. This will ensure most effective use of the installation as well as enable all machines to be serviced during a single visit.

The controllers will eliminate the need for operators to manually change settings on a continuous basis. Higher-end versions have the ability to be programmed to change the installation’s sequences automatically.
