CalorVal BTU Analyzer Brochure

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.

Added Cost Savings Benefit in Coil Coating

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. 

5 key reasons to choose PrevEx in Coil Coating

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 Problems: Response Time

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 Problems: Sensor Accuracy

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 Problems: Maintenance is burdensome

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.

Top 3 Problems in Coil Coating Atmospheres

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

Back to the Basics: Reliability

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

Back to the Basics: Duct Mounting and Sample Probes

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.

Back to the Basics: Response Factors

The most notable feature of the Flame Temperature analyzer is the uniformity of response factors for a wide variety of combustible gases.

Response factors show how a sensor that is calibrated for one particular gas, usually a "reference" gas, will read when exposed to other gases. If two gases both have the same response factor, they respond equally, unless the sensor is non-linear (infrared), in which case linearization of the signal can introduce more error, or less, depending on the individual characteristics of the sensor for each gas.
