Vapor Detection Applications

  • Gas detection analyzers for coil coating industry

    Coil Coating is a high-temperature solvent vapor monitoring application in which rolls of aluminum or steel are coated with a color finish, oven cured to desired specs and sold to makers of cans, rain gutters, home appliances, building & automotive products and other fabrications. Coil coating requires the use of our PrevEx Flammability Analyzers to monitor the flammability of the solvent vapor driven off during the drying process. PrevEx analyzers accurately measure solvent mixtures and can withstand the temperatures required to prevent sample clogging in coil coating plants.

    Water Vapor Permeation Analyzers for Packaging Industry

    For packaging film barriers, the Systech Illinois range of water vapor permeation analyzers offer a wide measurement range with precision temperature, humidity and flow control. These analyzers utilise the Coulometric P2O5 sensor, which is more sensitive and stable than infra-red and does not require calibration. The P2O5 is the primary method for absolute moisture measurement.

    Gas Detection Solutions for Fertilizer Manufacturing

    Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example, water vapor) – such interferences complicate other optical techniques using IR or UV.

  • Gas detection analyzers for processing ovens & dryers

    Many industries are involved in coating products with solvent-borne materials and then employing ovens or dryers to remove the solvents from the finished product. The key hazard is an explosion from the build up of solvent vapors in the oven or dryer atmosphere. This buildup could occur by a malfunction in the production process such as: a sudden or improper amount of coating, a change in ventilation controls or excessive speed. In any of these cases, the concentration of flammable vapor has an opportunity to rise above safe levels, creating a potentially explosive mixture of vapor in air.

    Gas analysis & monitoring system for leak searching

    Many chemical compounds and gas are invisible to the naked eye. But there are many companies that make intensive use both during and after the production process. The manner and frequency with which companies are required to monitor, document, report and rectify any escape of volatile gaseous compounds are established by regulations extremely rigid. The technology most widely used is the “Imaging Camera” or “sniffer technology.” “When we look for gas leaks, check all systems in places that may or may not have been previously identified. These controls are carried out regularly and are very important after a shutdown.
