Is it time to replace your CEMS Analyzer?
Every Continuous Emissions Monitoring System (CEMS) user wants to get the most serviceable life possible out their analyzers. CEMS Analyzers typically last 15 years or more and often their lifespan is dictated by the manufacturer’s ability to continue support of them. Most often, parts availability eventually puts an end to a manufacturers ability to continue support.
Some manufacturers are constantly making upgrades to their analyzers and discontinue support in a subscribed amount of time after the new analyzers come to market (typically seven (7) years). Other manufacturers will continue to support analyzers as long as absolutely possible.
The bottom line is that there is a balancing act between saving money and putting off a major purchase, and unsupported/obsolete analyzers with fading reliability that affect a CEMS uptime and availability. Eventually the cost of repairs and the potential risk of downtime becomes too great, demanding action (i.e. purchase replacement analyzers).
Along these lines, the information complied below is to help users determine where they are in the lifecycle of their analyzers. Keep in mind there are always choices as most CEMS analyzers are interchangeable and replacements are typically plug-and-play. Monitoring Solutions is always available to help with analyzer upgrades; from choosing the correct one to assisting with installation and even certification testing. Don’t hesitate to contact us if we can be of assistance.
