Who We Are

CMS’s primary focus is the inspection and repair of tubular air pre-heaters, heat exchangers, and clinker coolers. Over our thirty year history, we have gained international renown for our expertise and experience.

An often neglected system, the air pre-heater serves an essential role in the efficiency of the boiler system and in the pollution control process. At CMS, we have significantly advanced the technology, understanding, and approach for the inspection and repair of this system. Regardless of the industry, CMS provides long term operational solutions that protect the air pre-heater from erosion, corrosion, and fly ash fouling. Our inspection and repair solutions have helped hundreds of utilities optimize their operational efficiency, regain capacity, and improve the performance of their pollution control systems.

Corrosion Monitoring Services, Inc. has been helping customers assess, monitor, and repair air heaters since 1982. In fact, CMS has repaired or rebuilt thousands of tubular air pre-heaters (APH) in North America and overseas. In the process, the company has established a reputation for delivering quality products and services on-time and on-budget.

CMS has significantly advanced APH technology by developing patented and proprietary solutions that significantly improve equipment performance and service life. Analysis data proves that under-performing air heaters can negatively affect other important parts of your operation. This equipment includes gas and air fans, bag houses, precipitators and scrubbers that depend on the APH units to deliver preheated air within a specific pressure, volume and temperature range.

Today, CMS is the only company in the world that offers complete, performance assessment, integrated corrosion assessment and repair services for tubular air pre-heaters. Our inspection and assessment programs provide an accurate and comprehensive picture of the entire air heater system, pinpointing all areas of tube damage and potential financial impacts.
