Operator models

Smart, safe, secure.

You can choose between two different operator models: With the SIGMA AIR UTILITY contracting model, we assume full responsibility for the compressed air system, whereas with the SIGMA FLEX contracting model, you retain operator responsibility. We take care of the rest under a usage agreement.


Smart, safe, secure

Kaeser customers who choose our SIGMA AIR UTILITY contracting model save on the costs of investing in their own compressed air station and instead purchase the compressed air at a pre-agreed price per cubic metre.

By having Kaeser operate and manage their compressed air supply, customers also benefit from maximum energy efficiency and system reliability over the long term. Our service centre constantly monitors the system and ensures that it is kept up to date both from technological and energy efficiency perspectives.

Your advantages

  • Carefree compressed air: 
    You focus on your core business – we take care of the rest.
  • From fixed costs to variable costs: 
    Your business assets remain liquid and untouched.
  • A compressed air system as large as your needs: 
    We can easily adjust capacity for you – upwards or downwards.


Predictable and flexible

The SIGMA FLEX operator model allows you to use a new compressed air system without the need for investment costs. This provides you with maximum costing security and allows you to benefit from all of the advantages that an advanced compressed air system has to offer, e.g. outstanding energy efficiency. Needless to say, we take care of all service and maintenance tasks. The model uses a demand-based billing plan.

Your advantages

  • Great flexibility:
    The system can always be adapted to your (growing) needs – even during the contract period.
  • Inclusion of existing machines:
    Existing machines can also be included in the compressed air station.
  • Integrated service:
    You not only get a compressed air system, but also a full service package covering servicing and maintenance.
  • Maximum cost transparency:
    Thanks to the fixed basic rate, you can enjoy maximum planning security with no unexpected service costs.
