Equalizer 4.0 and Optimizer 4.0 Controllers

Advanced Central Compressor Control Systems

A centralised compressor control system is one of the most effective ways to improve the performance, reliability, and efficiency of your compressed air installation. Reducing energy consumption, lowering CO2 emissions, and maintaining a stable air supply are essential for modern industrial facilities. The Atlas Copco Equalizer EQ4.0 and Optimizer 4.0 are designed specifically to meet these demands, helping you achieve a smarter, more cost-effective air system.

Key System Benefits

Improved Overall Efficiency

Reduce the total lifecycle cost of your compressed air system by ensuring every compressor operates in its most efficient range.

Lower Energy Consumption

Achieve up to 10% energy savings on installations with mixed compressor sizes and technologies.

Smarter Pressure Control

Keep air pressure within a tight, predefined band to minimise energy waste and deliver a consistent, reliable air supply.

Intelligent Machine Selection

Automatically prioritise the most economical and modern compressors while limiting reliance on older or less efficient units.

Optimised Use of VSD Technology

Ensure continuous use of Variable Speed Drive compressors - the most efficient option for fluctuating air demand.

Coordinated Multi-Compressor Operation

Allow multiple VSD and Turbo compressors to work together, each within its peak performance zone.

Scheduled Shutdowns

Programme automatic shutdowns during nights, weekends, and holidays to eliminate unnecessary running hours and reduce costs.

Reliability & Uptime Built In

A stable, well-balanced air system prevents downtime and reduces the strain on individual machines. The controller’s load-balancing logic ensures run hours are evenly distributed across all connected compressors, preventing overuse of any single unit. This results in:

  • Increased system stability
  • Fewer breakdowns
  • Lower maintenance costs
  • Longer equipment lifespan

Group Control Made Simple

The ES-based control technology allows compressors and dryers to work as coordinated groups. With equalised running hours, servicing can be carried out simultaneously, reducing disruption and avoiding repeated call-outs.

The system also supports automatic shutdown during non-production periods, further lowering operating costs.

The Result? A Smarter, More Efficient Compressed Air System

The Equalizer 4.0 and Optimizer 4.0 deliver complete visibility and control over your compressed air network — helping you reduce energy usage, stabilise system pressure, and maintain consistent performance across all connected machines.
