The most reliable monitoring systems

LEL Monitoring

A LEL Monitoring System is an analytical system able to check the flammable solvent concentrations.
The flammable proprierties of the solvents and the high temperatures, can create dangerous risks of explosion. In order to avoid these dangerous conditions, the concentration must be checked by a LEL monitoring system and kept below the limit of explosion.

Infrared (IR) LEL Monitoring Systems. The sample gas passes through a measurement cell (optical path).The infrared light emitted is absorbed by the sample gas and then it gets caught by a receiver. The intensity, between the Infrared light emitted by the source and the Infrared light caught by the receiver, is directly proportional to the solvent concentration inside the sample gas analyzed. Our Infrared sensors are the only sensors on the market, factory calibrated. They are completely calibration free and they don’t require any further in-field recalibration during their entire life cycle (15 years).

Flame Ionization Detector (FID) LEL Monitoring Systems. Through the combustion of the flame between clean air, hydrogen and sample gas, the FID is able to create hydrocarbon’s ions. These ions are captured by a small metallic web, located around the flame, and they induce a current. This current is directly proportioned to the solvent concentration inside the sample gas analyzed. The Flame Ionization Detector (FID) is considered the fastest, more precise and more reliable sensor on the market, in the pharmaceutical, tobacco, food packaging and especially converting.

Automatic Air Recirculation Control Systems. Through our LEL monitoring systems and our the Automatic Air Recirculation Control Systems, we are able to recycle up to 90% of the hot air in discharge; as a result, the recycling of this hot air, allows profitable energy savings and the air flow reduction allows downsizing on air treatment plants.

Air Treatment Plants VOC Monitoring

Flame Ionization Detector (FID) Emission Monitoring Systems. In case of Solvent Recovery  Plant (SRP) the flow rate, coming from the production lines, determines the numbers of the activated carbon adsorbers and the solvent concentration determines the energy consumption required to recover each kg of solvent.In case of Regenerative Thermal Oxidizers (RTO), the flow rate of the air, coming from the production lines, determines the dimension of the systems and the solvent concentration determines the natural gas consumption required for the burner; if the concentration of the solvent, contained in the air exceeds a certain threshold (± 5gr/m3), the system becomes self-sustainable.

Residual Solvent in Flexible Packaging

Fast Residual Solvent Analyzer. Finished printed products of all types must be analyzed to determine residual solvent levels, to detect and avoid potential waste. A specialized Gas Chromatograph can be implemented at this point of the process in order to check all printed materials and quickly provide an analysis or residual solvent levels.
