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. Explore a complete line of compressed air treatment equipment that Kaeser offers.
