DEC.LEL™ - LEL control systems

LEL (Lower Explosive Limit) automatic recirculation systems are mandatory when you are planning to install a VOC abatement system (solvent recovery - activated carbon, or oxidizer). Furthermore, increasing energy costs, are requesting our customers (flexible packaging and converting industries, using rotogravures, flexo and lamination machines) to explore and evaluate energy saving technologies, in order to increase their competitiveness in the global market.

Thanks to DEC.LEL™ recirculation system, we can reach:

  • increased safety, due to LEL monitoring;
  • reduction of the exhausted air flow (SLA), thanks to the increase of solvent concentration (g/m3);
  • electrical energy saving;
  • thermal energy saving (up to ~40÷50%, depending on ambient temperature);
  • reduction of the investment for the activated carbon solvent recovery or the thermal oxidizer system;
  • reduction of the operating costs (i.e. specific consumptions, recovery cost).

    Three different LEL control and recirculation processes are applied:

  • DEC.SER™: single element recirculation;
  • DEC.SMR™: single machine recirculation;
  • DEC.GMR™: more machines, common recirculation.

    • LEL Monitoring Technologies

    The following LEL monitoring technologies are part of our portfolio:

  • FID (flame ionization detector);
  • IR (infra-red sensor);
  • CAT (catalytic sensor);
  • FTA (flame temperature analyzer).
