Due to the nature of high temperature processes, those operating above 200°C, some older model LFL Systems have a life expectancy of 10-15 years. In critical applications like these, it is essential to ensure that the LFL System is up to date and fully operational, if not, it might be time for an upgrade.
There are 2 common areas of the LFL System that are often affected by the inherent demands of running a process at high temperatures:
- Accuracy - High temperatures can present problems with sensor accuracy. Because most analyzers become contaminated, they must be checked and adjusted whenever there is a change in the solvents or coatings being run — leading to inconsistent and unreliable readings.
- Maintenance - In these types of demanding process conditions maintenance can often be a burden. Sample lines can clog, pumps can break down, and analyzer elements can become fouled — all resulting in excessive labor and costly downtime.
When considering the option of upgrading your LFL System it is important to take these two areas into consideration because in no way should the high temperatures of the application impede an analyzer’s operation. Look for an analyzer that:
- Has a corrosion resistant, heated sample delivery train - The heat eliminates condensation and withstands corrosive elements, leaving you with an accurate representation of your process
- Collects the sample using an aspirator, driven by compressed air - There is no pump or blower, eliminating the unpredictability of moving parts, assuring you of the highest level of accuracy
- Mounts directly on the oven wall or exhaust duct without external sample lines - This shortens the sample path significantly, reducing sample delivery time & accelerating response time
By upgrading to an LFL System with these features, you can eliminate the common challenges associated with higher temperature applications, so service can be reduced to routine maintenance.
