Rotogravure printing is a competitive marketplace. According to the GAA, “gravure has strengthened its position of dominance in both the publishing & packaging segments”. They are a part of an evolving industry, trying to keep up with consumer, geographical & environmental trends, which often comes down to whoever can print the fastest, at the lowest cost, wins. But how can you safely expand your plant to keep up with these demands? Automating Damper Control.
Most of you already know that you must have LFL analyzers in place for safety, but did you know that once you’ve done that, the NFPA-86 Standard for Ovens and Furnaces allows for additional solvent vapor analyzers to be installed onto the process to specifically control damper positions?
By adding the additional analyzers to safely automate the dampers, you can minimize the amount of ventilation air needed to maintain a safe LEL level in your ovens, thus saving money on heated air costs. As the solvent vapor concentrations varied from one production run to another, you can control the ventilation rate accordingly.
Since the gravure process has a wide variation of solvent loads (often from 5% LFL to 40% LF!), by automating damper control you can reduce your product costs and be as competitive as possible. Read how one of our package printing customers did just that.
