According to the flexible packaging association, the Flexible Packaging industry is the second largest packaging segment in the USA, with $31.1 billion in sales in the United States in 2014, while directly employing approximately 79 thousand people.

Flexible packaging converters range from small manufacturing companies operating a single facility, to large integrated corporations with up to 34 individual plant locations.

We are excited to introduce the CalorVal BTU Analyzer Brochure to our library.

The CalorVal is our micro-combustion calorimeter. Because of its unique construction and operating technology, it is the optimum analyzer for directly measuring the total heating value of varying waste gas streams of industrial processes.

Fire codes and safety laws limit the maximum solvent concentration allowable to 25% of the LFL under worst case operation. Large volumes of ventilation air must be heated and circulated to keep the solvent vapors in the ovens at safe operating levels.

However, if a flammable vapor analyzer is installed as a safety control, the maximum allowable concentration is 50% of the LFL, which means not as much air has to be heated to dilute the vapors. 

For the past few weeks we've talked about the problems that plague the coil coating application, including: maintenance, sensor accuracy, and response time. However, there is a solution to all three.

Coil coating line managers report that they experience three basic problems in solvent vapor monitoring, we've discussed the maintenance and accuracy issues, now let's look at response time:

Coil coating line managers report that they experience three basic problems in solvent vapor monitoring, last week we looked at maintenance issues, this week the focus is on accuracy: 

Sensor accuracy is a problem. Because most analyzers have a wide solvent response factor, they must be checked and adjusted whenever there is a change in the solvents or coatings being run. 

Coil coating line managers report that they experience three basic problems in solvent vapor monitoring, this week let’s address the first one: 

1. Maintenance is burdensome. Sample lines clog, pumps break down, and analyzer elements become fouled - all resulting in excessive labor and costly downtime. 

Coil coating ovens typically operate at high temperatures, with some zones at over 800°F. This temperature range is needed to cure organic polymer coatings to their substrate materials.

Coil coating line managers report that they experience three basic problems in solvent vapor monitoring: 

The Flame Temperature Analyzer has some important reliability features not found in other types:

The direct mounting of the analyzer to a process duct has two main benefits: 

1. eliminates the time delay associated with a long sample line 
2. makes it easier to keep the sample heated sufficiently to prevent condensation 

Even a very short section of relatively cold sample line can have a very serious effect on the analyzer accuracy and reliability.
