CEMS Winterization

Posted on December 21, 2021

With the arrival of colder temperatures, there are some factors that can heavily influence the reliability of Dilution and Extractive CEMS systems.

For dilution CEMS systems, it is extremely important that the air be as clean and dry as possible, allowing for the best stability of the system. As important as it is, air supply is also often the most overlooked when it comes to winterizing a CEMS.

Carbon steel air headers typically supply the CEMS air supply lines. When in constant contact with moisture, especially in open/uninsulated lines, rust and other particulates can be introduced into the CEMS. This situation will also have a disastrous impact on successful CEMS operations.

Winterizing the CEMS air supply should include the following:

1) Inspect air lines that feed the individual CEMS and heat trace or insulate any open piping that may be in direct contact with decreasing ambient temperatures.

2) Check moisture auto-drains throughout the supply lines.

3) Develop or schedule air cleanup package maintenance

There are many other weather factors that can affect dilution CEMS operation. Unconditioned air can and will create many issues with your CEMS, lead to misdiagnosis, and create failures of multiple hardware components.
