System controller for compressed air systems
Compressed air is one of your biggest utility costs. Too often, compressors in multi-unit systems operate on their individual control signals and are not well integrated. Much energy is wasted by running more machines than necessary and at higher pressures than needed. Other problems include fluctuating pressure, as well as increased maintenance and repair costs due to excess valve cycling and motor starts. Kaeser’s Sigma Air Manager 4.0 offers complete  compressed air system management for chemical plants and facilities by tying your compressors, blowers, or vacuum units together into a secure Sigma Network. SAM 4.0 can also balance load hours for more effective maintenance scheduling.

What is an ADA?
Kaeser's Air Demand Analysis (ADA) is our unique approach to comprehensive air system audits. Without interrupting daily plant operations, our proprietary ADA program provides a complete and accurate air demand and consumption profile. We can tailor this audit to any size system.

Kaeser's SmartPipe is a modular aluminum pipe for compressed air installations, offering both lower installation costs and lower long-term operating costs. From small shops to large industrial systems, SmartPipe is great for all facilities and is available in sizes up to 8" pipe diameter.

Compressed air applications range from general purpose shop air to breathing air - with a wide range of applications in between.  Because the application determines the type of air treatment required, the first step in meeting your air treatment needs is to look closely and specifically at your air quality requirements.

  • To accurately evaluate a blower system’s performance, an Air Demand Analysis (ADA) measures the actual flow, pressure, and power consumption over a set period. This provides a baseline that shows which units are running, when they are running, and how efficient the entire system is in terms of specific performance (kW/100 cfm).

  • Compressed air quality is mission critical in manufacturing. When determining the right air treatment components for a compressed air system, there is a great deal to keep in mind. In this paper, we discuss compressed air quality and how it impacts operating costs and production. 

  • With over ten thousand air systems audits under our belt, we've seen it all and learned a few things. One of the most common problems we see is that most systems have far more capacity than needed. On average, users operate at 44% of peak capacity. It's so common, we'd say it is an epidemic, and even our own customers are not immune despite our efforts to inoculate with education. This article takes a look at some actual examples of over-sized systems and the costs that resulted. Learn how to properly plan for a compressed air system and what your options are with an existing system.

  • Kaeser has expanded its product range with the introduction of magnetic bearing turbo blowers.

    Turbo blowers are used wherever pressures as high as 20 psi are needed, e.g. wastewater treatment, aerobic fermentation and flue gas desulphurization.

    For flow rates up to 4700 cfm there is the 200 hp series, and the 400 hp series for flow rates up to 10,500 cfm. Both of these model ranges include three PillAerator designs. Each impeller design delivers different pressures and flow rates.

  • For many years, Kaeser has been building custom engineered solutions for our industrial compressor customers, and these are a natural fit for wastewater application.

Al Moreno, Kaeser's District Manager, then highlights the company's screw blower technology, followed by Global Product Manager Peter Werhahn, who provides the business case for investing in turbo blowers.

  • Kaeser Compressors' rotary screw blowers offer superior performance, fast installation, low noise operation, and lowest life cycle costs to help wastewater treatment plant operators and designers revolutionize their plant's aeration system. 

  • Precision management of dissolved oxygen (DO) allows wastewater treatment plant operators to maintain optimal biological conditions in their activated sludge basins. However, older blowers and a lack of advanced aeration oversight can sabotage that effort while substantially wasting money.

  • Upgrading the aeration system in a wastewater operation is typically burdensome because of the design work, permits, construction, and commissioning required for a structure before a new blower system can be installed. An affordable, purpose-built blower system delivered in its own secure, weatherproof enclosure may be a viable alternative that can be commissioned sooner and at lower cost than one that requires renovations or new construction.

  • Wastewater plants could significantly benefit from air system performance audits for aeration blower systems. 

  • It’s common for wastewater treatment plant operators and design engineers to get comfortable with one type of blower for aeration. However, multiple blower technologies are available to consider when designing a new system. Understanding the difference between them, as well as the pros and cons of each based on the specific application, is critical to the decision-making process.

  • This article gives an inside look at factors that impact pressure stability and operating efficiency, how to identify potential drawbacks in an air system, and what to specify for greater efficiency.

  • Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

  • The next big thing is here and it’s the Industrial Internet of Things (IIoT). With pundits waxing philosophical on this big breakthrough, it’s hard to cut through the noise and understand what the IIoT actually is and how it applies to individual plants. I offer the following as a definition. The IIoT means collecting, interpreting, and applying data to actively improve processes or operations. To understand how the IIoT applies to a wastewater treatment plant, look no further than your front yard.

  • System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.

  • As part of her tour marking the opening of this year’s Hannover Messe, German Chancellor Angela Merkel and Polish Prime Minister Beata Szydlo paid a visit to Kaeser Kompressoren’s trade show booth.
