Improve Your System Performance and reduce your total cost of ownership with a comprehensive compressed air system audit completed by a Professional Engineer.

Operational excellence is key to remaining competitive. Improving production rates, raising quality, and minimizing resource costs drive competitive success. Your compressed air system impacts all three and presents a great opportunity for improvement in your plant.

In the course of helping thousands of customers save millions of dollars through compressed air energy best practices we have improved conventional air audit techniques to develop our unique Kaeser Air Demand Analysis (ADA) program. No other approach to compressed air system analysis offers this combination of comprehensiveness, convenience, and affordability.

Energy cost savings

The Stakes are High

Compressed air is likely your biggest energy user. Most compressed air systems operate inefficiently. Improper adjustments, leaks, artificial demand, and poor system design all contribute to unnecessarily high energy costs. Many of these same systems can't deliver the desired air volume at the needed pressure. This results in lower production rates and quality, as well as higher life cycle costs. Many facilities can achieve savings up to 50% by studying and optimizing their compressed air systems.

There are other important incentives to reduce energy consumption. From the consumers' perspective, the industrial "carbon footprint" is a growing concern, so environmental stewardship is also a strategic issue. According to the latest estimates, optimizing existing industrial motor-driven systems (including compressors) could reduce energy consumption by as much as 7 percent. If this is one of your strategic goals, examining your compressed air system will yield significant improvements.

Kaeser is a leader in making the most reliable and energy-efficient compressed air products you can buy. Still, having energy-efficient components is only part of the efficiency picture and that the greatest efficiency gains are often achieved through system design. For many years, Kaeser has been helping customers do just that: design better compressed air systems that are dependable and energy-efficient.  They've led the way in promoting proper piping, storage, and controls, while others continue to focus merely on the initial capital cost of the equipment.

Benefits of an ADA

Significantly reduce energy costs by identifying and eliminating inefficiencies in your system.

  • Reduce production scrap/waste by providing consistent pressure to production equipment.
  • Cut air compressor maintenance costs by optimizing run time and reducing excess cycling.
  • Reduce production equipment maintenance costs through improved air quality.
  • Minimize downtime by reducing compressor maintenance intervals.
  • Reduce your carbon footprint with lower energy consumption.
  • Help qualify for utility rebate programs to pay for system upgrades.

The ADA Process

Suitable for analyzing large or small systems, Kaeser's ADA is an exceptional tool. With the data we gather, our compressed air specialists identify areas for improvement in energy savings, air delivery, and pressure stability throughout your plant.

Our field service experts have the knowledge, experience, and tools to study true life cycle costs. They can evaluate your air system and make solid recommendations that will greatly reduce your energy costs and even increase productivity. More efficient systems idle less, run less, and as a result, last longer.


Site Survey

The first step in an Air Demand Analysis is to become familiar with your air system. Discussing your goals for the assessment, areas of concern, production needs, and air quality issues help lay the groundwork for a successful optimization project.

From there, we review all the component of your air system, including:

  • Compressor controls
  • Overall system controls
  • Intermediate storage and distribution piping
  • Air treatment equipment

We also investigate cycles and trends in plant processes to see how they relate to system dynamics and identify possible correlations with system performance issues. Using this information, we can baseline system performance more accurately and build a better system demand profile that takes into account dynamic production needs.



Your Air Solutions Canada field representative will visit your site to:

  • Collect detailed information on your system components, environmental conditions, and physical layout.
  • Collect appropriate supporting graphical data such as plant blueprints, schematic drawings, sketches, and photographs.
  • Gather input on specific problems your plant is currently facing and discuss desired outcomes.


Data Logging

To obtain a detailed, accurate picture of your compressed air demand and system dynamics, we install a variety of instruments and sensors customized to your unique system. Since you pay for kWh, we measure kilowatts—not amps—to give the most cost-effective calculation. This approach creates a complete picture of system activity - including leaks, which are often most apparent during off-peak production periods.


Comprehensive Analysis

Using proprietary KAESER ADA software, we identify waste and poor practices, such as leaks or artificial demand caused by operating at unnecessarily high pressures. It also shows energy loss due to pressure drops in distribution piping.

We create detailed time-stamped charts from the recorded data. These are used to analyze your system from several perspectives and offer insight into your operating activities and corresponding air requirements.

This step also helps to identify deficiencies in the air supply, storage, or piping along with any control issues.


Kaeser Energy Savings System (KESS)

We use powerful Kaeser Energy Savings System (KESS) software to simulate power requirements of different system scenarios. This helps identify solutions that will achieve the greatest efficiency without compromising pressure/flow requirements or system reliability.


Analysis & Reccommendations

Your Air Demand Analysis isn't complete until we issue a final analysis and recommendations. This includes a side-by-side comparison of multiple scenarios showing their purchase price, energy costs, and savings.

Recommendations often focus on making adjustments to controls, storage, or piping rather than buying new equipment. Armed with these ideas, you'll be able to determine the most cost-effective system changes.

Measurable Results

Here are some examples of recent Kaeser ADAs that delivered significant and immediate benefits to customers:

  • A precision metal fabricator was using two 40-hp modulating compressors to supply their flow, but struggling with pressure fluctuations. An ADA revealed the system was oversized and a single 20 hp dual control compressor could handle the demand. This has reduced their energy costs by 40%—even though their average demand has increased by 28%.
  • A music studio equipment manufacturer struggled with pressure, flow, and air quality problems. The ADA recommended a system that would deliver steady pressure and flow and an energy-efficient dryer to address the moisture problems for $36,110 in annual energy savings.
  • A plant manufacturing turbines for hydroelectric power plants reduced their system-specific power from 62.0 kW/100 cfm down to 16.7 kW/100 cfm by switching from multiple modulating control compressors to energy-efficient rotary screw compressors with a system master controller.
  • A furniture manufacturer struggled with vacuum hold-down. The ADA identified flow—not vacuum—was the problem and designed a new system with vacuum blowers. This solution reduced the horsepower by 200 hp and is saving them $99,000 in energy and maintenance costs every year.
  • At a metal products plant, an ADA identified $51,000 in savings for fixing system leaks in $17,000 in savings for adding proper system controls.
  • Thanks to recommendations from an ADA, a Tier I automotive parts supplier was able to reduce their power consumption by 865,440 kWh—the equivalent of removing 100 homes from the power grid for a year. The energy and maintenance savings totalled $133,720. On top of that, they received a utility rebate of $71,579.
  • An automotive parts manufacturer with multiple, uncontrolled centrifugals was spending $699,799 in energy costs and approximately $109,000 on annual maintenance. The ADA identified $129,046 in energy savings—along with drastically reduced maintenance costs—for a 17-month simple payback period.
  • A cement manufacturer conducted ADA's at five of their plants. Implementing the recommendations resulted in a 12,658-ton reduction in CO² and average monthly savings amongst the plants as high as 64%.

Whether your motivations are financial or environmental, an efficient air system will deliver the right amount of air at the lowest life cycle cost.
