Catalytic Oxidizers (CATOX™)

Catalytic Oxidizers (CATOX™) use a catalyst to promote the oxidation reaction to occur.  Catalytic oxidation requires less than half the heat (500-600°F) needed for thermal oxidation (1,400-1,600°F) and creates an opportunity to substantially reduce fuel expenses and material costs. The addition of a Recuperative (heat exchanger) further reduces the need for supplemental fuel. In many cases, the system requires no supplemental fuel in an operating condition known as “autocatalytic”.

 The Air Clear Advantage in Catalytic Oxidation

  • Proven Conversion of hydrocarbons or VOCs
    to have negligible photo chemical re activity. can be as high as 99.9% efficiency with 50% less energy use
  • Lower operating temperatures result in lower NOX
    emissions, without significant formation of CO.
  • Air Clear’s CATOX™ CATALYTIC OXIDIZER Systems are smaller and lighter than their thermal counterparts, requiring a smaller footprint.
  • Our flameless catalytic electric heat systems do not generate NOX emissions.
  • A variety of catalyst types are available to optimize performance for each particular application. Even halogenated organic compounds can be controlled with the proper catalyst.
  • Requirements for MACT, BACT, LAER and RACT making it the preferred oxidation technology for many applications.
  • Air Clear Catalytic Oxidizers Meet Federal, State and Local EPA Emissions Requirements Catalytic Oxidizers are recognized as the Best Available Control Technology (BACT) and Maximum Control Technology (MACT) for many industrial applications.
  • Combination catalytic/thermal systems are available for specialized requirements such as remediation projects such as soil vapor extraction.
  • The Air Clear Catalytic Recuperative Oxidizer is designed to provide reliable stable operation over a wide range of process conditions – flows and VOC loadings – wide variety of processes. The Air-Clear Catalytic Oxidizer is also an excellent choice for intermittent ‘ON-OFF’ use.
  • Air Clear’s Custom design meets your specific environmental and project objectives in the most cost effective way.
  • Best Value Featuring primary and secondary heat recovery the Air-Clear Catalytic Oxidizer can often MAKE YOU MONEY!
  • Factory Acceptance Test (FAT) – reduces commissioning and start up time by running a thorough diagnostic system check PRIOR to shipment. In house fabrication provides AC with the ability to maintain quality and delivery control at the lowest cost by eliminating Second tier fabricators.
