    What you need to know:

    Catalytic Products International, Inc designs each QUADRANT SRS Thermal Oxidizer based on the exact needs of your application. With 43 years of thermal oxidizer design as a basis of our expertise, you can be assured that your QUADRANT SRS Thermal Oxidizer is an economical solution to applications in the tape coating, release liner, adhesive coating, and other processes that use in the manufacturing operations.

    Silicon is a necessary additive for various coated products.  It is vaporized in the drying process that forces a large percentage into the dryer exhaust. Silicone when heated above certain temperatures will form an inorganic particulate - Silicon DiOxide (SiO2) SiO2 clings to hot metallic surfaces and forms a destructive and efficiency robbing barrier layer. SiO2 will poison catalytic oxidizers. SiO2 can effect RTO valving and clog ceramic media. SiO2 will create boundary layers in typical shell and tube heat exchangers. Catalytic Products International developed the QUADRANT SRS Thermal Oxidizer to provide an economical answer to the disastrous effects of SiO2. 

    What you need to know:

    • Adhesives of all types are regulated as coatings under environmental Programs
    • Water-based adhesives usually contain some (small amount) of solvent that should be accounted for in a permit - add on controls are generally not required for water-based adhesives

    • Solvent-based adhesives will usually result in emission rates that require add-on controls

    • Pressure-sensitive tapes and labels coatings may be subject to a federal standard (NSPS Subpart RR) in additional to applicable state regulations

    • Silicone in an exhaust stream can foul heat exchangers in recuperative thermal oxidizer and media in regenerative thermal oxidizer - certain designs can minimize this effect however.
