Increasing energy and raw material costs, as well as a growing sensitivity toward emission controls, are pushing all?major converting and flexible?packaging companies to explore new technologies designed to drastically reduce costs ?associated? with air treating? systems and?energy saving.

NIRA: Safety, energy saving and environmental respect in a single evolved solution

Infrared (IR) and Flame Ionization Detector (FID) LEL Monitoring Systems and Automatic Air Recirculation Control Systems, for flow rate in discharge optimization and energy saving in printing and converting applications.

LEL (Lower Explosion Limit) Monitoring Systems and Air treatment Systems are essential elements of daily processes for printing and converting companies.

A correct implementation of LEL Monitoring Systems, whether Infrared or Flame Ionization, not only allows full compliance with all current laws and regulations, but also guarantees respect of the environment, with a significant reduction of Volatile Organic Compounds emitted in the atmosphere, and more interestingly, offering a remarkable opportunity for thermal energy saving and investment reduction on air treating systems.

By law, in evacuation from drying stations, hot air containing a certain concentration of solvents must be treated, before being released into the atmosphere. This air can be treated through Regenerative Thermal Oxidizers (RTO) or Solvent Recovery Plants (SRP). Measuring the solvent concentration and managing that hot air flow allows companies to save large amounts of thermal energy and reduces the dimension, and consequently the required investment on air treating systems.

NIRA's LEL Monitoring and Air Recirculation Systems give you the power to optimize thermal energy saving and downsize the investment in air treating systems as much as possible, all the while guaranteeing the maximum safety and reliability during your production cycles: our Infrared (IR) and Flame Ionization Detector (FID) LEL Monitoring Systems and Automatic Air Recirculation Control Systems are the means by which you can ensure safety, obtain thermal energy savings, reduce your investments and respect the environment.

NIRA also manufacturers stationary and portable TOC Analyzers for emission control (Mercury and Aries), Fast Residual Solvent Analyzer (Neptune), and process control systems (Scorpio and Taurus) to control Regenerative Thermal Oxidizers (RTO) and Solvent Recovery Plants (SRP).

NIRA AUTOMATIC AIR RECIRCULATION SYSTEMS FOR WATER-BASED AND SOLVENT-BASED APPLICATION久久视热频国产精品

During normal solvent-based applications, the solvent concentration in evacuation from the drying stations is detected through a LEL monitoring system (Lower Explosion Level).

If the solvent concentration is lower than its permissible level, the exhaust air, in evacuation from drying stations, can be recycled and sent back at the inlet air duct. These air recirculation systems allow thermal energy saving and flow rate optimization. Usually, during water-based applications, these air recirculation systems are excluded or they are set to a low air recirculation percentages (± 30%).

To achieve an air recirculation system during water-based applications, it's?possible to use Relative Humidity sensors, but unfortunately these sensors cannot be exposed to any vapors of solvents because it may alter their readings and even lead to their breakup.

In order to avoid this issue, we have developed an external sampling system. The sample gas (vapor) is sucked, by an ejector, inside the sampling system. Inside the sampling system, the sample gas (vapor) is analyzed by a Relative Humidity sensor; if the relative humidity of the gas is lower than a certain level, the exhaust air can be recycled and sent back at the inlet air duct. Considering the high temperature inside the drying stations during water-based applications (±100°C), these innovating air recirculation systems will allow a huge energy saving, up to 50%, of your actual thermal energy consumption.

NOTE: The NIRA automatic air recirculation systems for water-based applications can be combined together with any other type of automatic air recirculation system for solvent-based applications.
