Sigma Air Utility


Sigma Air Utility (SAU) is a proven solution. Kaeser designs, builds, owns, operates, maintains, and stands behind your compressed air system. Kaeser guarantees the amount of air you need at the pressure you need, and at the quality you need. On top of that, it will be the most energy efficient air system you've ever had. 

Here's how Kaeser's Sigma Air Utility operator model works:
Your compressed air needs are analysed and an individual concept is drawn up based on what is required.
Based on the requirements Kaeser will build, install and operate the compressed air system.

Our Kaeser Teleservice, the logistics centre and our extensive global service network ensure that compressed air is available at all times.

With the Sigma Air Utility operator model, you pay a fixed basic price that covers an agreed quantity of compressed air. When larger amounts are needed, a fixed contractual price applies for the additional quantities used. All prices remain in effect for the entire duration of the contract, which means no price increases.

The advantages of Kaeser's Sigma Air Utility operator model:

No compressed air worries:

We offer everything from a single expert source: from the analysis of your compressed air needs to the machines and service. That lets you and your personnel concentrate fully on your core tasks.

From variable costs to predictable costs:

Sigma Air Utility takes the uncertainty out of operating an air system. Your employees will have time for other tasks. That means: You have more liquidity, are saved from tapping into your working capital and have greater flexibility in deploying your personnel.

A system scaled to your needs:

A competitive market brings ups and downs. Are you cutting back your output, or perhaps stepping it up? Are you relocating your operations? With Sigma Air Utility you can remain flexible. We will adjust your compressed air supply to your needs.

What is a Kaeser Compressor?

Kaeser compressors are arguably the most energy efficient, high-quality, industrial-grade air compressors available on the market today. Renowned for their inherent reliability, and durability, Kaeser compressors are “built for a lifetime”.

What types of compressors does Kaeser offer?

Kaeser manufactures a wide range of air compressors, including oil injected rotary screw compressors, reciprocating compressors, and oil free rotary screw machines. Electric and Diesel driven portable, and mobile options, are also available in different sizes and capacities and these can be rented, leased or purchased.

What are the advantages of Kaeser Compressors?

Kaesers patented Sigma profile air ends, produce up to 20% more cfm output volume than competitors equivalents. Exceptionally low noise levels, FIVE YEAR “bumper to bumper” warranty, and long service life, means that Kaeser is the right fit for all types of applications.

How do I select the right Kaeser Compressor for my application?

Selecting the right Kaeser compressor depends on various factors, such as your specific application requirements, air demand, operating conditions, available space, and budget. This is where the team at Air Solutions Canada comes in since we are Canada’s largest Kaeser authorized distributor. Our Compressed Air and Energy Solution Providers help you determine the most suitable equipment for your needs, taking into consideration factors such as required flow rate, pressure, duty cycle, site conditions and other specifications.

Are there incentives available for my compressed air project?

We have direct access to government funding, and this is available, at no cost to you, to assist you in updating, or improving your compressed air station and system. In order to benchmark your flow, pressure, and consumption demands, we recommend an Air Demand Analysis, (ADA) study. The results of this study ensure that we select, and engineer the correct equipment, and secure funding towards the project.

How do I maintain a Kaeser Compressor?

Proper maintenance is essential for ensuring the reliable and efficient operation of any compressor. Kaeser provides sensible and affordable maintenance schedules to keep your investment in good running order. Our prime objective is maximum “up time” and peace of mind. Regular maintenance tasks include checking and changing filters, inspecting connections, monitoring oil levels, greasing fittings, cleaning coolers, and performing other routine checks. It's also important to follow any recommended maintenance procedures provided by Kaeser and to use genuine Kaeser parts and lubricants.

With a multitude of operating technologies available, such as Variable Speed Drive, Load/Idle, Modulation, Quatro and Vario to control the compressor, our specific power wins out time and time again compared to others.

Heat recovery, zero compressed air loss drain traps and a master control system option, further improve efficiency, and reduce overall operating costs.
